HIV Self-Testing Can Be Liberating to HIV-Positive Women and Their Sexual Partners: A Qualitative Study in Kisumu, Western Kenya
Authors: Agot Kawango , Wango Gift-Noelle , Obonyo Beatrice , Thirumurthy Harsha 
Published: April 2020

Background: Nearly half of Kenyan men with HIV-positive partners do not know their partner’s status. We carried out a qualitative substudy to explore the experiences of a sample of HIV-positive women when distributing HIV self-tests (HIVST) to their sexual partners. Methods: HIV-positive women were invited for in-depth interviews to share their experiences in offering HIVST to their partners and how self-testing impacted their relationships. Results: Two hundred ninety-seven women were randomized to HIVST, 12 of whom self-reported being HIV positive and 11 participated in the interview. Self-testing procedures and interpretation of results were well understood. Participants were strategic in approaching their partners, thus avoided partner violence. Couple testing was high, which strengthened relationships, improved condom use, and empowered women to make joint decisions concerning their health. Conclusions: Giving HIV-positive women HIVST kits to distribute to their male partners is feasible and safe. Providers who have challenges reaching male partners with testing should consider HIVST.

Published: April 2020

Background: Family caregivers of older adults frequently navigate the health system for their loved ones. As older adults experience more medical issues, the interactions between caregivers and the health system can be fraught with conflicts. Objective: To characterize the conflicts that caregivers of older adults experience with the health-care system. Methods: A cross-sectional national online survey with open-ended questions was conducted among family caregivers ascertaining experiences with the health-care system. Qualitative thematic analysis was completed using constant comparative analysis and review by a third author. Results: Over a 2-month period, 97 caregivers completed the survey. Common themes where caregivers experienced conflicts were Difficulty With Accessing/Communicating With Providers, Delivery of Emergency Care, Disjointed Transitional Care, Unaddressed Clinical Concerns, and Financial. Caregivers reported needing to act as patient advocates in the conflicts with the health-care system. Conclusion: Understanding the conflicts that family caregivers encounter with the health system provides potential targets for future interventions to combat the challenges faced by caregivers of older adults and ultimately improve delivery of geriatric care.

AbstractBowlesite is a new mineral discovered in the Merensky Reef of the Rustenburg Platinum Mine, Bushveld complex, South Africa. Bowlesite forms tiny grains (maximum dimension 20 μm). It is associated with sulfides including chalcopyrite, pyrrhotite and pentlandite, in contact with silicates including plagioclase, pyroxene- and minor serpentine-subgroup and amphibole-supergroup minerals. Bowlesite is brittle and has a metallic lustre. In plane-polarised light, bowlesite has a light bluish grey colour. It shows weak bireflectance, no pleochroism and has weak anisotropism. Internal reflections were not observed. Reflectance values of bowlesite in air (R1, R2 in %) are: 50.3–51.4 at 470 nm, 48.5–48.9 at 546 nm, 47.9–48.6 at 589 nm and 47.8–48.7 at 650 nm. Ten spot analyses of bowlesite give the average composition: Pt 56.85, Pd 0.02, Sn 34.03 and S 9.15, total 100.05 wt.%, corresponding to the empirical formula (Pt1.001Pd0.001)Σ1.002Sn0.997S1.001, based on 3 atoms per formula unit. The simplified formula is PtSnS. Due to the small size of bowlesite, the crystal structure was solved and refined from the powder X-ray-diffraction data of synthetic PtSnS. The calculated density is 10.06 g⋅cm–3. The mineral is orthorhombic, space group: Pca21 (#29) with a = 6.11511(10), b = 6.12383(10), c = 6.09667(11) Å, V = 228.31(1) Å3 and Z = 4. Bowlesite is isotypic with cobaltite, CoAsS. The origin of bowlesite is probably related to low-T exsolution of Pt–Sn phases from high-T sulfides crystallised from the sulfide melt. The mineral honours Dr. John Bowles (Manchester University, UK) for his contributions to ore mineralogy and mineral deposits related to mafic–ultramafic rocks.

ObjectiveTo evaluate the effect of aerobic exercise training on asthma control, lung function and airway inflammation in adults with asthma.DesignSystematic review and meta-analysis.MethodsRandomised controlled trials investigating the effect of ≥8 weeks of aerobic exercise training on outcomes for asthma control, lung function and airway inflammation in adults with asthma were eligible for study. MEDLINE, Embase, CINAHL, PEDro and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched up to April 3, 2019. Risk of bias was assessed using the Cochrane Risk of Bias Tool.ResultsWe included 11 studies with a total of 543 adults with asthma. Participants' mean (range) age was 36.5 (22–54) years; 74.8% of participants were female and the mean (range) body mass index was 27.6 (23.2–38.1) kg·m−2. Interventions had a median (range) duration of 12 (8–12) weeks and included walking, jogging, spinning, treadmill running and other unspecified exercise training programmes. Exercise training improved asthma control with a standard mean difference (SMD) of −0.48 (−0.81–−0.16). Lung function slightly increased with an SMD of −0.36 (−0.72–0.00) in favour of exercise training. Exercise training had no apparent effect on markers of airway inflammation (SMD −0.03 (−0.41–0.36)).ConclusionsIn adults with asthma, aerobic exercise training has potential to improve asthma control and lung function, but not airway inflammation.

BackgroundPeople with pulmonary fibrosis often experience a protracted time to diagnosis, high symptom burden and limited disease information. This review aimed to identify the supportive care needs reported by people with pulmonary fibrosis and their caregivers.MethodsA systematic review was conducted according to PRISMA guidelines. Studies that investigated the supportive care needs of people with pulmonary fibrosis or their caregivers were included. Supportive care needs were extracted and mapped to eight pre-specified domains using a framework synthesis method.ResultsA total of 35 studies were included. The most frequently reported needs were in the domain of information/education, including information on supplemental oxygen, disease progression and prognosis, pharmacological treatments and end-of-life planning. Psychosocial/emotional needs were also frequently reported, including management of anxiety, anger, sadness and fear. An additional domain of “access to care” was identified that had not been specifieda priori; this included access to peer support, psychological support, specialist centres and support for families of people with pulmonary fibrosis.ConclusionPeople with pulmonary fibrosis report many unmet needs for supportive care, particularly related to insufficient information and lack of psychosocial support. These data can inform the development of comprehensive care models for people with pulmonary fibrosis and their loved ones.
Screening of organic micropollutants in raw and drinking water in the Yangtze River Delta, China
Authors: Ren Hanwei , Tröger Rikard , Ahrens Lutz , Wiberg Karin , Yin Daqiang 
Published: April 2020

Abstract
Background
The vast occurrence of organic micropollutants in surface waters has raised concerns about drinking water safety and public health. The Tai Hu Basin region in China, a typical developing and populous area, is facing the challenge of water pollution. To ensure drinking water safety, the knowledge on how treatment techniques and raw water quality affect the quality of finished water must be improved. The aim of the current study was to evaluate drinking water quality with respect to organic micropollutants and how the purity of the finished water depends on source water contamination and drinking water treatment strategies. Five drinking water treatment plants (DWTPs), using three different source waters in the Tai Hu River Basin, (i) Yangtze River, (ii) Wetland River Network, and (iii) Lake Tai Hu, were studied by analyzing 291 micropollutants in raw and finished water.

Results
Major differences in concentrations and composition profiles of organic micropollutants were observed between the source waters. Among the studied micropollutants, the dominating group was pesticides in the Wetland River Network and flame retardants in Yangtze. The total concentration of poly- and perfluoroalkyl substances (PFASs) in Tai Hu water was far higher than in the other samples. In total, 51 compounds were detected in the finished water, with an overall average total concentration of 730 ± 160 ng L−1. The removal efficiency of the detected compounds in the DWTPs averaged 24 ± 150%, which highlights the major challenge for the DWTPs in removing the emerging organic micropollutants through current treatment processes.

Conclusions
Our study showed that if the source water contains high levels of PFASs and organophosphorus flame retardants, even advanced treatment procedures are inefficient in removing the micropollutants, and the finished drinking water may contain cumulative levels of organic micropollutants in the ​µg L−1 range. On the other hand, if pesticides and pharmaceuticals dominate, a high overall treatment efficiencies may be obtained if advanced treatment techniques are used. The DWTPs are advised to use advanced treatment techniques or alternative water sources to guarantee the safety of drinking water. As surface water systems are highly impacted by upstream activities, efforts should also be made in the water sector for improving the surface water quality.
Food insecurity and food pantry use among transgender and gender non-conforming people in the Southeast United States
Authors: Russomanno Jennifer , Jabson Tree Jennifer M. 
Published: April 2020

Abstract
Background
Transgender and gender non-conforming (TGNC) people face high rates of poverty, joblessness, and homelessness, rendering this population vulnerable to experiencing food insecurity. Yet, there is almost no empirical evidence concerning food insecurity and the use of local and federal food assistance resources in the TGNC community. Food insecurity, the use of local and Federal food assistance resources, and associations with gender-related minority stressors and resilience using the Gender Minority Stress and Resilience (GMSR) scale among TGNC individuals living in the Southeast United States (U.S.) were documented in this study.

Methods
A cross-sectional online survey was conducted with TGNC people living in the Southeast U.S. Participants were recruited via targeted Facebook advertisements.

Results
In total, 105 TGNC people completed the survey; 79% of survey participants experienced food insecurity, 19% utilized Federal, and 22% utilized local food assistance resources. High levels of minority stress and community resilience were reported. The GMSR resilience scale Pride (aOR = 1.09, 95% CI 1.00–1.19, p = .04) was significantly associated with the use of local food pantries, but minority stressors were not. No significant associations were found between GMSR and food security.

Conclusion
TGNC people living in the Southeast U.S. experienced food insecurity, unstable housing, low wages, and social stigma that were a barrier to using emergency food resources. Multi-level public health solutions that address discriminatory legislative policies and create linkages between TGNC people and local and federal food assistance are required to address issues of food insecurity in the TGNC population.
Development of a clinical decision tool to reduce diagnostic testing for primary aldosteronism in patients with difficult-to-control hypertension

Published: April 2020

Abstract
Background
Satisfactory tools to preclude low-risk patients from intensive diagnostic testing for primary aldosteronism (PA) are lacking. Therefore, we aimed to develop a decision tool to determine which patients with difficult-to-control hypertension have a low probability of PA, thereby limiting the exposure to invasive testing while at the same time increasing the efficiency of testing in the remaining patients.

Methods
Data from consecutive patients with difficult-to-control hypertension, analysed through a standardized diagnostic protocol between January 2010 and October 2017 (n = 824), were included in this cross-sectional study. PA was diagnosed by a combined approach: 1) elevated aldosterone-to-renin ratio (> 5.0 pmol/fmol/s), confirmed with 2) non-suppressible aldosterone after standardized saline infusion (≥280 pmol/L). Multivariable logistic regression analyses including seven pre-specified clinical variables (age, systolic blood pressure, serum potassium, potassium supplementation, serum sodium, eGFR and HbA1c) was performed. After correction for optimism, test reliability, discriminative performance and test characteristics were determined.

Results
PA was diagnosed in 40 (4.9%) of 824 patients. Predicted probabilities of PA agreed well with observed frequencies and the c-statistic was 0.77 (95% confidence interval (95%CI) 0.70–0.83). Predicted probability cut-off values of 1.0–2.5% prevented unnecessary testing in 8–32% of the patients with difficult-to-control hypertension, carrying sensitivities of 0.98 (95%CI 0.96–0.99) and 0.92 (0.83–0.97), and negative predictive values of 0.99 (0.98–1.00) and 0.99 (0.97–0.99).

Conclusions
With a decision tool, based on seven easy-to-measure clinical variables, patients with a low probability of PA can be reliably selected and a considerable proportion of patients with difficult-to-control hypertension can be spared intensive diagnostic testing.
Inhibitory effect of novel Eugenol Tosylate Congeners on pathogenicity of Candida albicans
Authors: Lone Shabir Ahmad , Ahmad Aijaz 
Published: April 2020

Abstract
Background
The global prevalence of fungal diseases is increasing rapidly, which affects more than a billion people every year with significant mortality rate. On the other hand, the development of new drugs to treat these fungal infections is slow, while the current antifungal therapy is insufficient and associated with adverse side effects and emerging multidrug resistance. Therefore, development of novel antifungal drugs with least or no toxicity and multi-target mechanisms of action is an immediate priority. Natural products have long been known to possess antimicrobial activities and are source of new drugs. Currently, modifying natural products to synthesize derivatives/analogues are of great scientific focus for discovering novel drugs with improved potency and safety. Modifications in eugenol to synthesize eugenol derivatives with enhanced antifungal activity have already been reported.

Methods
In this study, three most active novel eugenol tosylate congeners (ETC-5, ETC-6 and ETC-7) were selected from our previous study to investigate their effect on major virulence factors of Candida albicans which include adherence, morphogenesis, hydrolytic enzymes secretion, biofilm formation and on expression of genes related to these virulence factors. Adherence and biofilm formation were studied by alamarBlue dye and XTT reduction assays respectively, hydrolytic enzyme secretion was evaluated by plate assays. Further, morphological transition was monitored microscopically and RT-qPCR was used to assess the gene expression levels.

Results
ETCs significantly inhibited adherence in C. albicans with an inhibition range of 16–66%, and completely inhibited the morphogenesis at MIC values. Inhibition of proteinase and phospholipase activity was in the range of 2–48% and 8–34% respectively. Test compounds also significantly inhibit biofilm formation in C. albicans in the range of 7–77%. Furthermore, RT-qPCR results indicated a significant down regulation in expression levels of genes (ALS1, ALS2, ALS3, ALS9, CPH1, HWP1, SAP1, SAP2, SAP3 and PLB1) in C. albicans cells after treated with ETCs.

Conclusion
The results indicated that these novel ETCs target major virulence factors of C. albicans and avert this commensal microbe to turn into pathogenic. However, further in-depth studies may facilitate the mechanisms involved by ETCs in targeting these virulence factors.
Mapping the Minnesota living with heart failure questionnaire (MLHFQ) to EQ-5D-5L in patients with heart failure
Authors: Kularatna Sanjeewa , Senanayake Sameera , Chen Gang , Parsonage William 
Published: April 2020

Abstract
Background
Mapping algorithms can be used to convert scores from a non-preference based instrument to health state utilities. The objective of this study was to develop mapping algorithms which will enable the Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores to be converted into EQ-5D-5L utility scores that can be used in heart failure related cost utility studies.

Method
Patients diagnosed with heart failure were recruited from Australia. Mapping algorithms were developed using both direct and indirect response mapping approach. Three model specifications were considered to predict the EQ-5D-5 L utility score using MLHFQ total score (Model 1), MLHFQ domain scores (Model 2), or MLHFQ item scores (Model 3). Six regression techniques, each of which has the capability to cope with either skewness, heteroscedasticity, ceiling effects and/or the potential presence of outliers in the data set were used to identify the optimal mapping functions for each of the three models. Goodness-of-fit of the models were assessed using six indicators. In the absence of an external validation dataset, predictive performance of was assessed using three-fold cross validation method. In the indirect response mapping, EQ. 5D 5 L responses were predicted separately using the MLHFQ item scores using ordered logit model.

Results
A total of 141 patients participated in the study. The lowest mean absolute error (MAE) was recorded from the multivariable fractional polynomials (MFP) model in all three-model specifications. Regarding the indirect response mapping, results showed that the performance was comparable with the direct mapping approach based on root mean squared error (RMSE) but was worse based on MAE.

Conclusion
The MLHFQ can be mapped onto EQ-5D-5 L utilities with good predictive accuracy using both direct and indirect response mapping techniques. The reported mapping algorithms would facilitate calculation of health utility for economic evaluations related to heart failure.
Translating insights from neuropsychiatric genetics and genomics for precision psychiatry
Authors: Rees Elliott , Owen Michael J. 
Published: April 2020

AbstractThe primary aim of precision medicine is to tailor healthcare more closely to the needs of individual patients. This requires progress in two areas: the development of more precise treatments and the ability to identify patients or groups of patients in the clinic for whom such treatments are likely to be the most effective. There is widespread optimism that advances in genomics will facilitate both of these endeavors. It can be argued that of all medical specialties psychiatry has most to gain in these respects, given its current reliance on syndromic diagnoses, the minimal foundation of existing mechanistic knowledge, and the substantial heritability of psychiatric phenotypes. Here, we review recent advances in psychiatric genomics and assess the likely impact of these findings on attempts to develop precision psychiatry. Emerging findings indicate a high degree of polygenicity and that genetic risk maps poorly onto the diagnostic categories used in the clinic. The highly polygenic and pleiotropic nature of psychiatric genetics will impact attempts to use genomic data for prediction and risk stratification, and also poses substantial challenges for conventional approaches to gaining biological insights from genetic findings. While there are many challenges to overcome, genomics is building an empirical platform upon which psychiatry can now progress towards better understanding of disease mechanisms, better treatments, and better ways of targeting treatments to the patients most likely to benefit, thus paving the way for precision psychiatry.
