SAN FRANCISCO—A new study has shown that hydroxyurea (HU) can improve lung function in young patients with sickle cell disease (SCD).
“Persons with sickle cell disease experience an annual decline in lung function that starts in childhood,” said study investigator Anya McLaren, MD, of The Hospital for Sick Children in Toronto, Ontario, Canada.
“This study is the first of its kind to look at the effect of hydroxyurea on lung function. We found that hydroxyurea improves annual pulmonary function decline in children with sickle cell disease by more than one-third.”
The study was presented at the ATS 2016 International Conference as abstract 7225.
For this study, Dr McLaren and her colleagues evaluated the effects of HU in 94 SCD patients. The patients’ average age at baseline was 11 (range, 6 to 20), 96% of patients had HbSS genotype, and 47% were male.
The patients were followed for 4 years after HU initiation. The investigators assessed lung function before and after HU initiation in a few ways.
They used the forced expiratory volume (FEV) test, which measures how much air a person can exhale during a forced breath. The amount of air can be measured during the first second of the forced breath (FEV1) and at later time points.
Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test. If the FEV1/FVC ratio is less than 80%, it indicates that an obstructive defect is present.
The investigators also assessed FEF25-75, or the forced expiratory flow at 25%–75% of FVC. This measurement helps determine if there is an obstruction in the airway.
In addition, the team measured total lung capacity.
Results
The investigators found no significant change in total lung capacity, FVC, or FEV1/FVC predicted measurements after patients began receiving HU.
However, there were significant improvements in both FEV1 and FEF25-75 after treatment.
The annual rate of decline in predicted FEV1 and FEF25-75 before patients started HU was -1.98%/year (95% CI -2.57 to -1.39) and -3.59%/year (95% CI -4.43 to -2.75), respectively.
After HU treatment began, there was a significant (P<0.05) improvement in the annual decline, to -1.28%/year (95% CI -1.79 to -0.76) and -2.88%/year (95% CI -3.49 to -2.28), respectively.
The investigators noted that changes in FEV1 and FEF25-75 were independent of a patient’s age at baseline and the time from HU therapy initiation.
Dr McLaren pointed out that HU is underused in SCD patients, likely because clinicians are concerned about patient non-compliance and afraid of potential side effects, particularly carcinogenesis. But some of those fears may be unfounded, she said.
“Long-term observational studies suggest beneficial effects [of HU] without excessive damage to bone marrow, deleterious effects on growth and development, altered fertility, accumulation of mutations, or increased carcinogenicity,” Dr McLaren said.
“Evidence that lung function may be better preserved while on hydroxyurea may encourage compliance and adherence to this medication for patients with sickle cell disease. In combination with the established safety data, it hopefully will promote physician recommendations for hydroxyurea initiation and encouragement of compliance.”

Creating ‘real’ HSCs in the lab
in the bone marrow
Scientists believe they have come one step closer to creating hematopoietic stem cells (HSCs) that are just like the real thing.
“Our work focuses on finding a way to generate a supply of these life-saving hematopoietic stem cells in the lab so that they are a perfect match to the patient in need of a transplant,” said Hanna Mikkola, MD, PhD, of the University of California, Los Angeles.
“One big challenge is that when we try to create hematopoietic stem cells from pluripotent stem cells in the lab, they don’t acquire the same abilities of the real hematopoietic stem cells found in the body.”
Dr Mikkola and her colleagues described their attempts to overcome this challenge in Nature Cell Biology.
The researchers tried to create HSCs from pluripotent stem cells, but when they compared the lab-created cells to HSCs found in the body, they found that HOXA genes weren’t activated in the lab-created cells.
The team also discovered that HOXA genes help HSCs maintain their stem-cell attributes, such as the ability to self-renew.
“Without the ability to self-renew, hematopoietic stem cells cannot be used for transplantation therapies,” said Vincenzo Calvanese, PhD, an assistant project scientist in Dr Mikkola’s lab.
“Our findings show that the activation of HOXA genes can be used as a marker for hematopoietic stem cells that have acquired the capacity to renew themselves.”
The researchers’ next challenge was to pinpoint the naturally occurring process that activates HOXA genes so they could try to replicate the process in the lab.
They found that mimicking the effects of retinoic acid acts like a switch that turns on the HOXA genes during HSC development.
“Inducing retinoic acid activity at a very specific time in cell development makes our lab-created cells more similar to the real hematopoietic stem cells found in the body,” said Diana Dou, a graduate student in Dr Mikkola’s lab.
“This is an important step forward as we work to develop hematopoietic stem cells for transplantation therapies for life-threatening blood diseases.”
The researchers’ next step will be to refine the process they’ve developed in order to produce lab-created HSCs that have—and maintain—all the functions of human HSCs.

FDA alert: Canagliflozin use may be associated with toe, foot amputations
Interim safety results from an ongoing clinical trial found an increase in leg and foot amputations, mostly affecting the toes, in patients treated with the diabetes medicine canagliflozin, according to an FDA Drug Safety Communication on May 18, 2016.
The agency currently is investigating the safety issue but has yet to determine if taking canagliflozin is associated with an increased risk of leg and foot amputations. A sodium-glucose cotransporter 2 inhibitor, canagliflozin is marketed as Invokana and Invokamet by Janssen Pharmaceuticals, and was approved by the FDA in March 2013.
“Patients should not stop or change their diabetes medicines without first talking to their health care professional,” the communication states. “Doing so can lead to uncontrolled blood sugar levels that can be harmful. Over time, this can cause serious problems, including blindness, nerve and kidney damage, and heart disease. Patients taking canagliflozin should notify their health care professionals right away if they notice any new pain or tenderness, sores or ulcers, or infections in their legs or feet.”
The agency advises health care professionals to follow the recommendations in the canagliflozin drug labels and to monitor patients for the signs and symptoms described above.
Upon its approval, the FDA required five postmarketing studies for canagliflozin: a cardiovascular outcomes trial; an enhanced pharmacovigilance program to monitor for malignancies, serious cases of pancreatitis, severe hypersensitivity reactions, photosensitivity reactions, liver abnormalities, and adverse pregnancy outcomes; a bone safety study; and two pediatric studies under the Pediatric Research Equity Act (PREA), including a pharmacokinetic and pharmacodynamic study and a safety and efficacy study. In late 2015, investigators determined that the risk of bone fracture is increased with canagliflozin treatment.
Individuals who experience side effects while taking canagliflozin should submit a report through the FDA’s MedWatch program, or contact 1-800-332-1088 for more information.

Early palliative care for cancer patients benefits caregivers
Introducing palliative care in combination with standard oncology care immediately following a cancer diagnosis results in improved quality of life and lower incidence of depression for caregivers of cancer patients.
“The integration of palliative care can improve patient care but the evidence is lacking about whether or not there are benefits [for] caregivers,” Dr. Areej El-Jawahri of Massachusetts General Hospital, Boston, said in a presscast leading up to the annual meeting of the American Society of Clinical Oncology.
“This study suggests that early palliative care creates a powerful positive feedback loop in families facing cancer. While patients receive a direct benefit from early palliative care, their caregivers experience a positive downstream effect, which may make it easier for them to care for their loved ones,” she said.
Investigators enrolled 275 family caregivers of patients newly diagnosed with incurable lung or gastrointestinal cancers. Patients were randomly assigned to receive early palliative care in addition to standard oncology care or to receive standard oncology care alone.
Palliative care involved a multifaceted team including nurses, social workers, and psychologists. The palliative care intervention was patient focused, and caregivers, who were defined as a relative or friend identified by the patient as the primary caregiver, were not required to attend palliative care appointments. However, about 50% of caregivers did attend, according to Dr. El-Jawahri.
At time of enrollment and then at time points 12 and 14 weeks post enrollment, caregivers completed standard questionnaires, the 36-Item Short Form Health Survey and the Hospital Anxiety and Depression Scale, that assessed quality of life and mood.
Twelve weeks after the cancer diagnosis, caregivers who received early palliative care reported significantly lower depression symptoms while vitality and social functioning improved. For patients who did not receive early palliative care, their caregivers’ vitality and social functioning decreased.
“This is the first study showing a positive impact of a patient-focused palliative care intervention on family caregivers,” said Dr. El-Jawahri.
“This study really points out that we have so many ways to help our patients and their families,” Dr. Julie Vose, president of ASCO, said during the presscast.

Angiosome revascularization improves limb salvage
YES: The importance of the concept is established.
An angiosome is a three-dimensional anatomic unit of tissue fed by a single-source artery. The angiosome theory was first investigated in the plastic surgical literature by Taylor in the British Journal of Plastic Surgery in 1987,1 describing 40 angiosomes throughout the body. In the lower extremity, six distinct angiosomes have been defined; one arising from the anterior tibial artery (dorsalis pedis), two from the peroneal artery (the lateral calcaneal branch and the anterior perforating branch), and three from the posterior tibial artery (the calcaneal branch, the medial plantar branch, and the lateral plantar branch).2 Indirect connections known as choke vessels exist to enhance perfusion between angiosomes.
The question arises as to whether angiosome-specific revascularization enhances the healing of ischemic tissue loss of the lower extremity. Is direct revascularization of the appropriate angiosome an important part of the planning process for such revascularization efforts? Personal experience with 60 consecutive bypasses for ischemic lower extremity wounds left little doubt that angiosome-specific revascularization enhanced healing. Direct revascularization obtained 91% healing, compared with 62% when revascularization was performed to an artery which indirectly perfused the angiosome where the wound was located.3 There was also a trend for faster healing with direct angiosome revascularization. Other investigators have reported similar findings. Kret and colleagues found similar results for bypass, reporting complete healing in 78% of 106 limbs with direct revascularization with only 46% healing after bypass resulting in indirect angiosome revascularization. These authors noted that a “significant predictor for wound healing and reduced healing time was angiosome revascularization.”4
Consideration of the appropriate angiosome may be even more important for endovascular techniques in determining the target artery for revascularization. Iida et al investigated 200 ischemic ulcers, showing that healing was greatly enhanced by direct revascularization of the angiosome in which the wound was located.5 Kabra examined a mixed cohort of bypass and endovascular procedures and documented increased healing with angiosome revascularization for both modalities in treating critical limb ischemia, therefore, advising that angiosomes should be considered whenever possible.6 This is also an important concept for those diabetic ulcers in need of robust perfusion for healing. Alexandrescu demonstrated improved healing for diabetic ischemic ulcers after endovascular therapy with direct angiosome revascularization, concluding, “an angiosome model of perfusion helps the treatment of diabetic foot ulcers.”7 The group in Helsinki documented statistically significant better healing with endovascular revascularization of the appropriate angiosome in more than 250 patients with ischemic diabetic ulcers, surmising that the angiosome model is important for ulcer healing in diabetic patients.8
Given the many series, from around the world, confirming the impact of direct revascularization of the appropriate angiosome for a wound or non-healing ulcer to enhance healing, the importance of this concept in planning lower extremity revascularization has been established. There are certainly many considerations in planning revascularization such as patient presentation, arterial anatomy, and conduit or device selection. However, as revascularization of the appropriate wound angiosome results in more complete and rapid healing, it is irrefutable that the angiosome concept should be a consideration in planning revascularization for healing and limb preservation.

NO: Only a guide, not an absolute.
Despite an aggressive approach to revascularization, amputation rates of up to 20% can occur despite a patent bypass.1 This has led to enthusiasm for an angiosome-based revascularization strategy for the management of ischemic foot lesions.2-4 There is no question that clinicians would opt to revascularize a blood vessel that directly feeds an involved angiosome if the vessel is easily accessible, is of good quality, and has good run-off. The issue arises if the target vessel does not meet that criteria and the surgeon is forced to intervene on an alternative feeding vessel (indirect revascularization).
There have been several studies which compare outcomes after direct and indirect revascularization strategies and they conclude that direct revascularization has better limb salvage rates.2 However, most of the studies were retrospective and details on the status and quality of the pedal arch were not consistently evaluated. Rashid et al studied the impact of direct angiosome revascularization on the healing of the foot and reported that healing and time to healing of foot tissue loss were significantly influenced by the quality of the pedal arch rather than the angiosome revascularized.3
Because of variations in the arterial anatomy of the foot,5 inconsistencies in the extent of an angiosome and the collateral connections between angiosomes are frequent, suggesting that the angiosome that needs to be revascularized may not be perfused by the predicted artery. This helps explain why technical success may not always equate directly with clinical success, as corroborated by indocyanine green (ICG) imaging and white-light tissue spectrophotometry.6 It is also important to emphasize that in their initial publication, Taylor and Palmer emphasized that the basis of their proposed angiosome concept was on the structural anatomy of the feeder vessel territory. They did not and could not assess the perfusion levels and extent of the feeder vessel with their corresponding choke vessels.
Forefoot procedures, such as trans-metatarsal amputations, frequently interrupt this foot arch. Likewise, a large proportion of patients with renal insufficiency and/or diabetes mellitus present with extensive foot wounds with deep infection that may result in compartmentalization within the foot. In one series, only one third of patients had a single angiosome involved in the tissue loss, 45% of patients had two angiosomes involved and more than 20% of patients had three angiosomes involved.7 Patients with more than one angiosome affected by extensive tissue loss are not easily analyzed using the angiosome-oriented concept and so attempts at classifying the intervention as being direct or indirect is problematic.
Studies analyzing the utility of the angiosome concept need to be careful in analyzing the extent of the territories encompassed by the wounds. More importantly, many interventionalists equate tibial or peroneal revascularization with angiosomal revascularization. This may not be the case if the terminal branches are diseased and pedal loop interventions may still be necessary.
In summary, the angiosome model should not be used as an absolute strategy for interventions on critical limb ischemia patients but should be a guide to assist with a patient-specific strategy for revascularization. Further well-structured prospective studies are needed to assess the value of integrating the interangiosome concept, the status of the pedal arch, and the anatomic-physiologic perfusion angiosome model.

YES: The importance of the concept is established.
An angiosome is a three-dimensional anatomic unit of tissue fed by a single-source artery. The angiosome theory was first investigated in the plastic surgical literature by Taylor in the British Journal of Plastic Surgery in 1987,1 describing 40 angiosomes throughout the body. In the lower extremity, six distinct angiosomes have been defined; one arising from the anterior tibial artery (dorsalis pedis), two from the peroneal artery (the lateral calcaneal branch and the anterior perforating branch), and three from the posterior tibial artery (the calcaneal branch, the medial plantar branch, and the lateral plantar branch).2 Indirect connections known as choke vessels exist to enhance perfusion between angiosomes.
The question arises as to whether angiosome-specific revascularization enhances the healing of ischemic tissue loss of the lower extremity. Is direct revascularization of the appropriate angiosome an important part of the planning process for such revascularization efforts? Personal experience with 60 consecutive bypasses for ischemic lower extremity wounds left little doubt that angiosome-specific revascularization enhanced healing. Direct revascularization obtained 91% healing, compared with 62% when revascularization was performed to an artery which indirectly perfused the angiosome where the wound was located.3 There was also a trend for faster healing with direct angiosome revascularization. Other investigators have reported similar findings. Kret and colleagues found similar results for bypass, reporting complete healing in 78% of 106 limbs with direct revascularization with only 46% healing after bypass resulting in indirect angiosome revascularization. These authors noted that a “significant predictor for wound healing and reduced healing time was angiosome revascularization.”4
Consideration of the appropriate angiosome may be even more important for endovascular techniques in determining the target artery for revascularization. Iida et al investigated 200 ischemic ulcers, showing that healing was greatly enhanced by direct revascularization of the angiosome in which the wound was located.5 Kabra examined a mixed cohort of bypass and endovascular procedures and documented increased healing with angiosome revascularization for both modalities in treating critical limb ischemia, therefore, advising that angiosomes should be considered whenever possible.6 This is also an important concept for those diabetic ulcers in need of robust perfusion for healing. Alexandrescu demonstrated improved healing for diabetic ischemic ulcers after endovascular therapy with direct angiosome revascularization, concluding, “an angiosome model of perfusion helps the treatment of diabetic foot ulcers.”7 The group in Helsinki documented statistically significant better healing with endovascular revascularization of the appropriate angiosome in more than 250 patients with ischemic diabetic ulcers, surmising that the angiosome model is important for ulcer healing in diabetic patients.8
Given the many series, from around the world, confirming the impact of direct revascularization of the appropriate angiosome for a wound or non-healing ulcer to enhance healing, the importance of this concept in planning lower extremity revascularization has been established. There are certainly many considerations in planning revascularization such as patient presentation, arterial anatomy, and conduit or device selection. However, as revascularization of the appropriate wound angiosome results in more complete and rapid healing, it is irrefutable that the angiosome concept should be a consideration in planning revascularization for healing and limb preservation.

NO: Only a guide, not an absolute.
Despite an aggressive approach to revascularization, amputation rates of up to 20% can occur despite a patent bypass.1 This has led to enthusiasm for an angiosome-based revascularization strategy for the management of ischemic foot lesions.2-4 There is no question that clinicians would opt to revascularize a blood vessel that directly feeds an involved angiosome if the vessel is easily accessible, is of good quality, and has good run-off. The issue arises if the target vessel does not meet that criteria and the surgeon is forced to intervene on an alternative feeding vessel (indirect revascularization).
There have been several studies which compare outcomes after direct and indirect revascularization strategies and they conclude that direct revascularization has better limb salvage rates.2 However, most of the studies were retrospective and details on the status and quality of the pedal arch were not consistently evaluated. Rashid et al studied the impact of direct angiosome revascularization on the healing of the foot and reported that healing and time to healing of foot tissue loss were significantly influenced by the quality of the pedal arch rather than the angiosome revascularized.3

Initiative dramatically raises HCV screening, treatment
A hepatitis C awareness initiative dramatically raised the rate of HCV screening and treatment in a large American Indian population – the ethnic group with the highest rate of HCV infection and HCV-related mortality in the United States, according to a report published May 13 in Morbidity and Mortality Weekly Report.
Cherokee Nation Health Services undertook the effort in 2012 to improve detection and management of HCV. It included a reminder in eligible patients’ electronic health records (EHRs) to offer screening; HCV education for primary care physicians and other health care providers; establishment of an HCV registry to monitor the clinical care of patients who initiated antiviral treatment; and outreach efforts by public health nurses to HCV patients, including home visits.
In 2014, an additional initiative was implemented to expand services for the rapidly increasing number of patients diagnosed as having HCV. This allowed a transition from having a single clinic staffed by only one caregiver with expertise in HCV management to five clinics staffed by three physicians, two nurse practitioners, and two pharmacists with HCV expertise, said Dr. Jorge Mera, director of infectious diseases, Cherokee Nation Health Services, Tulsa, Okla., and his associates.
An analysis of deidentified data in the HCV registry and EHRs showed that 92,012 patients aged 20 years and older had at least one visit with Cherokee Nation Health Services after the program was implemented, between October 2012 and July 2015. The proportion of this patient population that was tested for HCV antibodies rose fivefold, from 3.6% to 18.2% during the study period. A total of 715 patients were antibody positive, and 388 of them were found to have chronic HCV infection. Approximately 60% of these patients initiated antiviral treatment, and approximately 90% of them achieved a sustained virologic response and were essentially cured, Dr. Mera and his associates said (MMWR. 2016 May 13;65[18]:461-6).
The program included a component that particularly targeted baby boomers – patients born between 1945 and 1965 – for HCV screening. Across the Indian Health Service clinics in 34 states that adopted this component of the program, such screening increased fourfold in this high-risk population during the study period (MMWR. 2016 May 13;65[18]:467-9).
These efforts, the first of their kind in the United States, may help eliminate hepatitis C as a health disparity for American Indian/Alaska Native populations and also may serve as a model for other health care settings, the investigators added.

Veteran Suicide Prevention Efforts Under Scrutiny
In a House Veterans’ Affairs Committee hearing on efforts to prevent veteran suicide, the VA confirmed that it is focused on ensuring it has enough mental health care providers. The VA currently employs 5,500 psychologists and 3,203 psychiatrists. According to Maureen F. McCarthy, MD, deputy chief, VHA Office of Patient Care Services, the VA currently has 236 psychiatrist vacancies.
Veteran service organizations, House members, and the VA all agreed that hiring and retaining qualified mental health care providers is an essential component in reducing suicides. “We are aware that access to mental health care is one significant part of preventing suicide,” McCarthy said in prepared testimony. “VA is determined to address systemic problems with access to care in general and to mental health care, including substance use disorders in particular. VA has recommitted to a culture that puts the veteran first.”
As House members, veteran service organizations, and the VA have all admitted, the frequently quoted 22 veterans suicides each day statistic is based on dated and limited data. To better understand the scope of the problem, the VA is working with the CDC to obtain a more current and accurate count of veteran suicides—a move that many veterans advocacy groups have called for.
“Vietnam Veterans of America calls for an updated veteran suicide report that includes data from all 50 states and U.S. territories, and also strongly suggests that VA mental health services develop a nationwide strategy to address the problem of suicides among our older veterans—particularly Vietnam-era veterans,” Thomas J. Berger, PhD, executive director of the Veterans Health Council of the Vietnam Veterans of America (VVA) told the committee in his prepared remarks.
According to Dr. McCarthy, the data will be available later this summer and will accessible to researchers. “We so wanted to have this information to you by this hearing. We don’t,” she said.
Challenges Remain
Ensuring access to care is one of the VA’s chief challenges. “We have to change our messaging to be more welcoming to all veterans,” Dr. McCarthy told the committee. “There are still veterans out there that do not know that they are eligible for benefits.”
Another one of the challenges is streamlining the transition from the military to the VA. “VA research has indicated that rates of suicide among those who use VA services have not shown increases similar to those observed in all veterans and the general U.S. population,” McCarthy explained. “This research suggests that an improved health care transition between DoD and VA could help mitigate suicide risk as well as other increased risks of morbidity.” According to McCarthy, the VA and DoD are working to create a seamless transition for mental health medications from the DoD to the VA, following a safety review
Following up on the Preventing Veterans Suicide – A Call to Action summit, in March, VA announced 8 steps it planned to take to improve its suicide prevention programs. They are:
1. Elevating VA’s suicide-prevention program with additional resources to help manage and strengthen current programs and initiatives;
2. Meeting urgent mental health needs by providing veterans with same-day evaluations and access by the end of calendar year 2016;
3. Establishing a new standard of care by using measures of veteran-reported symptoms to tailor mental health treatments to individual needs;
4. Launching a new study, “Coming Home from Afghanistan and Iraq,” that will look at the impact of deployment and combat as it relates to suicide, mental health, and well-being;
5. Using predictive modeling to guide early interventions for suicide prevention;
6. Using data on suicide attempts and overdoses to guide strategies to prevent suicide;
7. Increasing the availability of naloxone rescue kits throughout VA to prevent deaths from opioid overdoses;
8. Enhancing veteran mental health access by establishing 3 regional telemental health hubs; and
9. Continuing to partner with the DoD on suicide prevention and other efforts for a seamless transition from military service to civilian life.
“While these initiatives are laudable, VVA also believes strongly that they cannot fully succeed without a significant increase in the recruitment, hiring, and retention of VA mental health staff, as well as timely access to VA mental health clinical facilities and programs, especially for our rural veterans,” Berger told the committee.

9. Continuing to partner with the DoD on suicide prevention and other efforts for a seamless transition from military service to civilian life.
“While these initiatives are laudable, VVA also believes strongly that they cannot fully succeed without a significant increase in the recruitment, hiring, and retention of VA mental health staff, as well as timely access to VA mental health clinical facilities and programs, especially for our rural veterans,” Berger told the committee.
In a House Veterans’ Affairs Committee hearing on efforts to prevent veteran suicide, the VA confirmed that it is focused on ensuring it has enough mental health care providers. The VA currently employs 5,500 psychologists and 3,203 psychiatrists. According to Maureen F. McCarthy, MD, deputy chief, VHA Office of Patient Care Services, the VA currently has 236 psychiatrist vacancies.
Veteran service organizations, House members, and the VA all agreed that hiring and retaining qualified mental health care providers is an essential component in reducing suicides. “We are aware that access to mental health care is one significant part of preventing suicide,” McCarthy said in prepared testimony. “VA is determined to address systemic problems with access to care in general and to mental health care, including substance use disorders in particular. VA has recommitted to a culture that puts the veteran first.”
As House members, veteran service organizations, and the VA have all admitted, the frequently quoted 22 veterans suicides each day statistic is based on dated and limited data. To better understand the scope of the problem, the VA is working with the CDC to obtain a more current and accurate count of veteran suicides—a move that many veterans advocacy groups have called for.
“Vietnam Veterans of America calls for an updated veteran suicide report that includes data from all 50 states and U.S. territories, and also strongly suggests that VA mental health services develop a nationwide strategy to address the problem of suicides among our older veterans—particularly Vietnam-era veterans,” Thomas J. Berger, PhD, executive director of the Veterans Health Council of the Vietnam Veterans of America (VVA) told the committee in his prepared remarks.
According to Dr. McCarthy, the data will be available later this summer and will accessible to researchers. “We so wanted to have this information to you by this hearing. We don’t,” she said.
Challenges Remain
Ensuring access to care is one of the VA’s chief challenges. “We have to change our messaging to be more welcoming to all veterans,” Dr. McCarthy told the committee. “There are still veterans out there that do not know that they are eligible for benefits.”
Another one of the challenges is streamlining the transition from the military to the VA. “VA research has indicated that rates of suicide among those who use VA services have not shown increases similar to those observed in all veterans and the general U.S. population,” McCarthy explained. “This research suggests that an improved health care transition between DoD and VA could help mitigate suicide risk as well as other increased risks of morbidity.” According to McCarthy, the VA and DoD are working to create a seamless transition for mental health medications from the DoD to the VA, following a safety review
Following up on the Preventing Veterans Suicide – A Call to Action summit, in March, VA announced 8 steps it planned to take to improve its suicide prevention programs. They are:
1. Elevating VA’s suicide-prevention program with additional resources to help manage and strengthen current programs and initiatives;
2. Meeting urgent mental health needs by providing veterans with same-day evaluations and access by the end of calendar year 2016;
3. Establishing a new standard of care by using measures of veteran-reported symptoms to tailor mental health treatments to individual needs;
4. Launching a new study, “Coming Home from Afghanistan and Iraq,” that will look at the impact of deployment and combat as it relates to suicide, mental health, and well-being;
5. Using predictive modeling to guide early interventions for suicide prevention;
6. Using data on suicide attempts and overdoses to guide strategies to prevent suicide;
7. Increasing the availability of naloxone rescue kits throughout VA to prevent deaths from opioid overdoses;
8. Enhancing veteran mental health access by establishing 3 regional telemental health hubs; and
9. Continuing to partner with the DoD on suicide prevention and other efforts for a seamless transition from military service to civilian life.
“While these initiatives are laudable, VVA also believes strongly that they cannot fully succeed without a significant increase in the recruitment, hiring, and retention of VA mental health staff, as well as timely access to VA mental health clinical facilities and programs, especially for our rural veterans,” Berger told the committee.
Painful vesicles on penis
The FP diagnosed this patient with genital herpes. The patient’s herpes culture came back positive and his rapid plasma reagin (RPR) and human immunodeficiency virus (HIV) tests were negative.
Genital herpes presents with multiple transient, painful vesicles that appear on the penis, vulva, buttocks, perineum, vagina, or cervix. The vesicles break down and become ulcers that develop crusts while healing. Recurrences typically occur 2 to 3 times a year. The duration is shorter and less painful than in primary infections. The lesions often heal completely by 8 to 10 days.
The gold standard of diagnosis is viral isolation by tissue culture or polymerase chain reaction (PCR) testing. The culture sensitivity rate is only 70% to 80% and depends upon the stage at which the specimen is collected. The sensitivity is highest in the vesicular stage and declines with ulceration and crusting. The tissue culture assay can be positive within 48 hours but may take longer.
PCR is extremely sensitive (96%) and specific (99%). PCR testing is generally used for cerebrospinal fluid testing in suspected herpes simplex virus encephalitis or meningitis. The Tzanck test and antigen detection tests have lower sensitivity rates than viral culture and should not be relied on for diagnosis.
Antiviral therapy is recommended for an initial genital herpes outbreak. Although systemic antiviral drugs can partially control the signs and symptoms of herpes episodes, they do not eradicate the latent virus. Acyclovir, famciclovir, and valacyclovir are equally effective for episodic treatment of genital herpes, but famciclovir appears somewhat less effective for suppression of viral shedding. Effective episodic treatment of herpes requires initiation of therapy during the prodrome period or within one day of lesion onset. Providing the patient with instructions to initiate treatment immediately when symptoms begin improves efficacy for future outbreaks. Patients with frequent recurrences can choose to take daily antiviral medication for prevention of new outbreaks.
It was too late to initiate antiviral therapy for this patient, so treatment was confined to oral over-the-counter analgesics and topical petrolatum. The FP counseled the patient about the nature of the disease, its transmissibility, and the likelihood of recurrence.

Child with fever, cough, and rash
The FP suspected that this patient had measles, but since it has a low prevalence in the United States, he confirmed the diagnosis with a specific serum immunoglobulin M antibody test. Measles is a highly communicable, acute, viral illness that is still one of the most serious infectious diseases in human history. Until the introduction of the measles-mumps-rubella vaccine, it was responsible for millions of deaths worldwide annually. Eradication of measles is possible, but the ease of transmission and the low percentage of nonimmunized population that is required for disease survival have made eradication extremely difficult.
The classic measles rash is maculopapular and blanches under pressure. The rash begins on the face and spreads centrifugally to involve the neck, trunk, and, finally, the extremities. This cranial-to-caudal rash progression is characteristic of measles. The cough may persist for up to 2 weeks. Fever persisting beyond the third day of rash suggests a measles-associated complication.
Postinfectious encephalomyelitis can also occur. Postinfectious encephalomyelitis is a demyelinating disease that presents during the recovery phase, and is thought to be caused by a postinfectious autoimmune response.
The treatment of measles is mostly supportive and patients will need to stay away from other individuals—particularly unimmunized children and adults, pregnant women, and immunocompromised people—until at least 4 days after rash onset. Suspected cases of measles should be reported immediately to the local or state department of health.
In this case, the child showed no evidence of pneumonia, neurological symptoms, or dehydration, so hospitalization was not needed. Fortunately, the mother and father had both been vaccinated as children and this was their only child. Antipyretics and fluids were recommended. The parents were told to avoid giving the child aspirin to prevent Reye’s syndrome.
The FP maintained contact with the family over the phone and the symptoms began resolving within a few days. The FP also reported the case to the local health department.

Emergency diverticulitis: Limited role seen for proximal diversion
LOS ANGELES – There is no difference in 30-day outcomes for patients undergoing emergency surgery for acute diverticulitis with primary anastomosis with or without proximal diversion, results from an analysis of national data showed.
“Traditionally, patients undergoing emergency surgery for diverticulitis were offered a Hartmann’s procedure,” lead study author Dr. Nathan Hite said at the annual meeting of the American Society of Colon and Rectal Surgeons. “Studies have suggested that resection with primary anastomosis and proximal diversion is a safe alternative to this procedure. That’s attractive because it’s usually a quicker operation and puts less physiologic stress on the patient. It still requires a trip to the operating room, an inpatient hospital stay, and carries a complication rate of up to 20%.”
In an effort to determine if there was a difference between 30-day outcomes in patients treated with resection and primary anastomosis with or without primary diversion, the researchers queried the American College of Surgeons National Quality Improvement Program (ACS-NSQIP) database from 2005 to 2013 to identify patients with a diagnosis of diverticula, diverticulosis, or diverticulosis of colon without bleeding who underwent emergency operations. They divided patients into two groups: 1,912 who underwent resection and primary anastomosis without proximal diversion (group 1) and 123 who underwent resection and primary anastomosis with proximal diversion (group 2). Both open and laparoscopic operations were included.
Dr. Hite, of the department of colon and rectal surgery at Ochsner Medical Center, Metairie, La., reported that the mean age of patients in groups 1 and 2 was 62 and 59 years, respectively. There were no differences in gender distribution but women were significantly older in both groups (P less than .0006). No significant differences between groups 1 and 2 were observed with respect to body mass index (29.1 vs. 28.1 kg/m2, respectively; P = .11), preoperative albumin (3.3 vs. 3.5 g/dL), preoperative hematocrit (35% vs. 28%), preoperative white blood count (13.4 vs. 13.7 x 103/mcL), or functional status (P = .71). Although patients in group 2 did not appear to be sicker at the time of surgery in terms of ASA class or wound class, they did have a higher incidence of diabetes and smoking, compared with their counterparts in group 1.
As for postoperative complications, there were no significant differences between groups 1 and 2 in the incidence of superficial skin infection (141 vs. 7; P = .76), organ space infection (36 vs. 5; P = .09), septic shock (126 vs. 3; P = .18), pulmonary embolism (20 vs. 3; P = .15), cerebrovascular accident (7 vs. 0; P = .5), myocardial infarction (15 vs. 0; P = .32), or death (88 vs. 2; P = .51). Patients in group 2 did have a significantly longer operating time, compared with those in group 1 (158 vs. 133 minutes; P less than .0001).
“Ultimately, the decision to perform a proximal diversion [or not] depends on many factors,” Dr. Hite concluded. “But our study suggests that if the patient is an appropriate candidate for reanastomosis, a diverting ostomy may be safely omitted.” He reported having no financial disclosures.

AT THE ASCRS ANNUAL MEETING
Key clinical point: Whether patients underwent primary anastomosis with or without proximal diversion in emergency surgery for diverticular disease has no impact on 30-day outcomes.
Major finding: Among patients undergoing emergency surgery for acute diverticulitis with primary anastomosis, no significant differences were seen in a number of 30-day outcomes when the procedure was performed without or with proximal diversion, including superficial skin infection (141 vs. 7, respectively; P = .76), organ space infection (36 vs. 5; P = .09), septic shock (126 vs. 3; P = .18), or death (88 vs. 2; P = .51).
Data source: A review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2005 to 2013 to identify 2,035 patients with a diagnosis of diverticula, diverticulosis, or diverticulosis of colon without bleeding who underwent emergency operations.
Disclosures: Dr. Hite reported having no financial disclosures.
