Are countries using global fund support to implement HIV drug resistance surveillance? A review of funded HIV grants

The Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund) is the largest funder of human immunodeficiency virus (HIV) prevention and treatment programs worldwide. Since 2002, the Global Fund has encouraged grant recipients to implement drug resistance surveillance (DRS) as part of treatment programs. We reviewed documentation of 147 grants funded in 2004-2008 (funding rounds 4-8) to assess grantees' use of funds to support HIV DRS. Overall, 94 grants (64%) described HIV DRS as part of the national treatment program. However, only 32 grants (22%) specifically documented DRS as a grant-funded activity. This review provides baseline information suggesting limited use by countries of Global Fund financing to support HIV DRS. Additional assessment is required to evaluate barriers to using Global Fund grants to support DRS.     

Mental Health Literacy of University Students in Vietnam and Cambodia

Mental health literacy (MHL) refers to knowledge and attitudes that shape the recognition, management, and prevention of mental disorders. While the topic has been exhaustively researched in Western countries, research from Southeast Asia still is limited. Previous studies in this field showed a moderate recognition of mental disorders, a high prevalence of stigmatizing attitudes and a low willingness to seek professional help among Southeastern-Asian populations. This study explored the level of MHL among university students from different parts of Vietnam and Cambodia. Correlations with influencing factors (gender, age, study year, educational attainment of the parents, urban/rural origin, ethnicity, personal experiences with mental disorders) were also explored. An online survey, using a 30-item Vietnamese version of the Mental Health Literacy Scale (MHLS), was conducted at six university sites in Vietnam and Cambodia. Data of 1032 students from different study branches were included. The MHL of Vietnamese and Cambodian university students was lower, compared to samples from Australia or the UK. Females and students with a personal experience of mental disorders (self or family) showed a significantly higher MHL. No differences in MHL were found between students from different socioeconomic backgrounds (professional attainment of parents, urban/rural origin). Findings on the influence of ethnicity were inconclusive. MHL needs to be improved among the university students of Vietnam and Cambodia. Mental health promotion should specifically target male students, students from STEM branches, and international students.     

Disparities in women’s cancer-related quality of life by Southern Appalachian residence

Purpose

The purpose was to determine whether Appalachian residence alone or in combination with violence was linked to poorer quality of life (QOL).

Methods

Women recently diagnosed and included in either the Kentucky or North Carolina Cancer Registries were interviewed by phone between 2009 and 2015 (n?=?3320; mean age?=?56.74). Response rates were similar by state (40.1 in Kentucky and 40.9% in North Carolina). Appalachian (N?=?990) versus non-Appalachian residents (N?=?2330) were hypothesized to have poorer QOL defined as (a) lower Functional Assessment of Cancer Therapy—General (FACT-G) scores and (b) more symptoms of depression, stress, or comorbid physical conditions. Lifetime intimate partner or sexual violence was first investigated as a moderator then mediator of regional differences. Multiple analyses of covariance (MANCOVA) models were used.

Results

Violence modified the effect of Appalachian residence on poorer QOL outcomes; FACT-G total scores (p?=?.02) were lowest for women living in Appalachia who had additionally experienced violence. Socioeconomic indicators appeared to mediate or explain differences in QOL outcomes by Appalachian residence such that when adjusting for income, education and insurance, Appalachian residence remained associated only with poorer physical QOL outcomes (p?<?.05).

Conclusions

While violence rates did not differ by residence, the combined effect of living in Appalachia and experiencing violence resulted in significantly greater impact on poorer QOL among women recently diagnosed with cancer. Clinical consideration of patients’ residence, socioeconomic status and violence experienced may help identify and mitigate the longer-term impact of these identifiable factors associated with poorer QOL.

     

Hospital clinical pharmacy services in Vietnam

Background Clinical pharmacy is key to the quality use of medicines. While there are different approaches in different countries, international perspectives may inform health service development. The Vietnamese Ministry of Health introduced a legal regulation of clinical pharmacy services in December 2012. Objective To describe the services, and to explore reported barriers and facilitators in implementing clinical pharmacy activities in Vietnamese hospitals after the introduction of Vietnamese Ministry of Health legal regulation. Setting Thirty-nine hospitals in Hanoi, Vietnam, including 22 provincial and 17 district hospitals. Method A mixed methods study was utilized. An online questionnaire was sent to the hospitals. In-depth interviews were conducted with pairs of nominated pharmacists at ten of these hospitals. The questionnaire focused on four areas: facilities, workforce, policies and clinical pharmacy activities. Main outcome measure Proportion of clinical pharmacy activities in hospitals. Themes in clinical pharmacy practice. Results 34/39 (87%) hospitals had established clinical pharmacy teams. Most activities were non-patient-specific (87%) while the preliminary patient-specific clinical pharmacy services were available in only 8/39 hospitals (21%). The most common non-patient-specific activities were providing medicines information (97%), reporting adverse drug reactions (97%), monitoring medication usage (97%). The patient specific activities varied widely between hospitals and were ad hoc. The main challenges reported were: lack of workforce and qualified clinical pharmacists. Conclusion While most hospitals had hospital-based pharmacy activities, the direct patient care was limited. Training, education and an expanded work forces are needed to improve clinical pharmacy services.

     

Arterial manifestations of Beh?et's disease. 12 cases

Out of 196 patients with Beh?et's disease, 12 (10 men and 2 women, mean age 34 +/- 7 years) had non-coronary arterial lesions. Beh?et's disease was complete in 4 patients. The arterial lesions had appeared 8.6 +/- 8 years on average (20 years at most) after the first sign of the disease. Three patients showed evidence of stenosis or occlusion involving one or several arteries. Eight patients had both stenotic and aneurysmal lesions. One patient had an arteriovenous fistula. Another developed a false aneurysm at the site of introduction of a femoral catheter. Yet another patient developed an anastomotic aneurysm one year after implantation of an abdominal aortic graft. In 2 cases histology showed fragmentation of the media associated with vasculitis of the vasa vasorum. Two patients with pulmonary aneurysm died of massive haemoptysis. In 2 patients combined corticosteroid and cyclophosphamide therapy failed to prevent the development of aneurysmal lesions. Phlebitis was associated with arterial involvement in 7 patients. Comparison between patients with or without arterial lesions showed no significant difference in time of onset of Beh?et's disease, sex, main clinical features and presence of HLA B5. Aneurysmal lesions respond poorly to medical treatment, and surgery is mandatory. Since recurrence at the site of anastomosis is possible, prolonged monitoring is required.     

Platelet adhesion and thrombus formation on subendothelium in platelets deficient in glycoproteins IIb-IIIa, Ib, and storage granules

Patients whose platelets are deficient in glycoprotein (GP) Ib, IIb- IIIa (thrombasthenia), or granule substances (storage pool deficiency, SPD) were studied to define further the properties of platelets that mediate platelet adhesion and thrombus formation on subendothelium. Both nonanticoagulated and citrated blood were exposed to everted, de- endothelialized rabbit vessel segments under controlled flow conditions and shear rates varying from 650 to 3,300 sec-1. Morphometry was used to measure platelet thrombus dimensions and the percentage of the subendothelial surface covered with contact (C) or spread (S) platelets. Adhesion was defined as C + S. The results in SPD demonstrated (1) reduced thrombus dimensions in delta-SPD (pure dense granule deficiency) in proportion to the magnitude of the dense granule defect; (2) an even greater reduction in thrombus dimensions in patients with combined deficiencies of alpha and dense granules (alpha delta-SPD); and (3) impaired platelet adhesion at several conditions in alpha delta-SPD and, in delta-SPD, a hematocrit-dependent impairment of adhesion in citrated blood at 2,600 sec-1. In thrombasthenia, platelets were present as a monolayer on the subendothelial surface in both nonanticoagulated and citrated blood, indicating an absolute requirement for GPIIb-IIIa in promoting platelet-platelet interaction at all shear rates and perfusion times. Two types of abnormalities in platelet-vessel wall interactions were observed. In nonanticoagulated blood, the percentage of platelets in the C phase was consistently increased at all shear rates, but C + S values were normal. These observations indicate that platelets deficient in GPIIb-IIIa do not spread normally on the subendothelial surface exposed to nonanticoagulated blood. With citrated blood, the C + S value in thrombasthenia was reduced at both 800 and 2,600 sec-1, as in von Willebrand's disease, and a similar degree of reduction (about 50%) was observed in normal blood treated with a monoclonal antibody to GPIIb- IIIa. The findings, together with theoretical considerations, are consistent with an hypothesis that GPIIb-IIIa mediates the spreading of platelets on subendothelium following the initial attachment through GPIb and that GPIIb-IIIa may be considered an adhesion site on the platelet membrane. Abnormalities of GPIIb-IIIa may, depending on the conditions of study, result in either increased values of C platelets or decreased values of C + S. The results of the study further suggest that a complex interaction of platelet granule factors and membrane GP mediate platelet adhesion and thrombus formation.     

Severe Malaria Not Responsive to Artemisinin Derivatives in Man Returning from Angola to Vietnam

Resistance to artemisinin derivatives, the most potent antimalarial drugs currently used, has emerged in Southeast Asia and threatens to spread to Africa. We report a case of malaria in a man who returned to Vietnam after 3 years in Angola that did not respond to intravenous artesunate and clindamycin or an oral artemisinin-based combination.
