Of 87,339 treatment admissions, 47.5% (n = 41,481) of patients had not accessed HTS in the prior 12 months. HTS was reported less frequently by patients whose primary substance of use was cannabis or those with polysubstance use (36.9% and 41.1%, respectively). None of the substance use sub-groups reported a testing rate above 70%. Compared to specific reference groups, logistic regression showed those with lower odds of HTS were 15-19 years (OR = 0.59); had primary-level education (OR = 0.51); were scholars/learners (OR = 0.27); and primarily cannabis users (OR = 0.64). Patients whose primary drug was heroin had higher odds of testing (OR = 2.45) as did those who injected drugs (OR = 2.86). Given the low coverage and decreased odds of self-reported HTS among sub-groups of patients in SSATCs, the integration of HIV services for PWUD should be a priority in South Africa and a focus of the national HIV strategy.The successful treatment of HIV infection relies on adherence to antiretroviral therapy (ART). Alcohol use remains a threat to ART adherence, including the beliefs held by people who drink alcohol that it is harmful to take ART when consuming alcohol (i.e., alcohol-ART interactive toxicity beliefs, AA-ITB). We reviewed the current research that has investigated AA-ITB and their relationship to intentional ART nonadherence. The review of 17 published studies found that AA-ITB are prevalent among people receiving ART and that AA-ITB are directly associated with ART nonadherence and incomplete HIV suppression. Family, friends and healthcare providers are common sources and reinforcers of AA-ITB. Studies suggest that AA-ITB may best be explained by the Medication Necessity and Concerns Beliefs Model, treating AA-ITB as a specific circumstance of medication concerns. Interventions are needed to communicate the realities of potential medication interactions and dispel myths that it is harmful to mix alcohol with ART, while not inadvertently suggesting that it is safe to drink with all medications, which could undermine adherence to ART by increasing alcohol use.We explored transactional sex and relationships (TSR) among South African adolescent girls and young women (AGYW) using (1) survey data from 4,399 AGYW aged 15-24 years, and (2) qualitative data from 237 AGYW and 38 male peers. Ten percent of sexually active AGYW reported having ever had transactional sex; 14% reported having stayed in a relationship for money or material items. Factors associated with higher reporting of TSR included HIV positivity, higher food insecurity, and alcohol use. Those AGYW who were between the ages of 20-24 years (OR 1.0; 95% CI 0.81-1.24), had a sexual partner older than her by 5 years or more (OR 1.89; 95% CI 1.58-2.26), and had a transactional relationship in the past (OR 61.1; 95% CI 47.37-78.76) were more likely to report having transactional sex. AGYW qualitative narratives included both assertions of agency in choosing to engage in TSR, and power inequities resulting in condomless sex. Our findings can inform interventions to addressing transactional sex and relationships, critical to South Africa's HIV response.Men who have sex with men (MSM) continue to constitute the majority of HIV incidence in Taiwan. This study examined the associations between five co-occurring psychosocial health conditions (PHCs)-childhood physical abuse (CPA), childhood sexual abuse (CSA), intimate partner violence (IPV), internalized homophobia (IH), and methamphetamine use (MU), and two outcomes (HIV infection and condomless anal sex) among a community sample of 1,000 Taiwanese MSM (mean age 28.5 years). Compared to MSM who had never experienced any PHC, MSM with one or more PHCs had greater than twofold higher odds of being HIV-positive, and those with three or more PHCs had twofold higher odds of having condomless anal sex. Interactive effects on HIV infection were identified from CPA + CSA + MU and CPA + IPV + MU. An interactive effect on condomless anal sex was detected between IH and MU. In order to control the escalating HIV epidemic among MSM in Taiwan, interventions are needed to address syndemic psychosocial health conditions.
To evaluate the impact of the Coronavirus disease of 2019 (COVID-19) pandemic on patients with migraine.

Self-reported data from a migraine tracking smartphone application, Migraine Buddy, were used. Data were collected from users who reported at least one attack in the Jan, Feb, Mar and Apr of 2018, 2019 and 2020. In addition, a survey was conducted to evaluate the impact of COVID-19 on migraine management.

On average, data from 124,717 users per month (mean age 36.3 ± 10.9years and 89% female) were collected. Overall, the mean frequency of migraine headache was higher in 2020 than in 2019 and higher in 2019 than in 2018. The four commonest headache triggers in 2018, 2019 and 2020 were stress in 39.7, 38.4 and 36.1%, lack of sleep in 25, 25 and 22.8%, neck pain, 20, 20.4 and 19.3 and anxiety in 19, 18.4 and 18.4% of participants, respectively. 1689 users participated in the survey and they reported that they preferred face-to-face (54.29%) to telehealth (11.9%) consultations.

An increase in migraine frequency from 2018 to 2020 was reported by the users of the mobile phone. This could reflect a real increase or change in reporting habits. Stress, lack of sleep, neck pain and anxiety were the commonest attack triggers. The frequency of these triggers decreased slightly in 2020 compared to 2019 and 2018. An increase in telehealth consultations with specialists was reported in the survey but migraine patients preferred face-to-face consultations.

Thus, in a tsetse-infested area, a spatial gradient of reducing tsetse habitat quality is potentially a gradient of increasing prospects for occurrence of stress in tsetse flies. This study investigated prevalence of trypanosome infection in Glossina morsitans morsitans and G. pallidipes along a transect line hypothesised to represent such a gradient, in relation to the edge of the tsetse belt and distribution of human settlements. This was undertaken in three sites located in Lundazi, Mpika and Rufunsa districts, respectively, in north-eastern Zambia. Human settlement was concentrated at the edge of the tsetse belt in the Mpika and Rufunsa sites and evenly distributed along transect line in the Lundazi site. Tsetse fly samples were collected using black-screen fly rounds and Epsilon traps. Detection of t Mpika and Rufunsa sites, increase in distance from human settlements entailed reduced likelihood of trypanosome infection, likely due to reducing tsetse habitat degradation, increasing availability of hosts, and hence increasing levels of nutrition and fat reserves, thus enhancing tsetse immunity against trypanosome infection.Adipogenesis is a multi-step process orchestrated by activation of numerous TFs, whose cooperation and regulatory network remain elusive. Activating transcription factor 4 (ATF4) is critical for adipogenesis, yet its regulatory network is unclarified. Here, we mapped genome-wide ATF4 binding landscape and its regulatory network by Chip-seq and RNA-seq and found ATF4 directly modulated transcription of genes enriching in fat cell differentiation. Motifs of TFs especially CTCF were found from ATF4 binding sites, suggesting a direct role of ATF4 in regulating adipogenesis associated with CTCF and other TFs. Deletion of CTCF attenuated adipogenesis while overexpression enhanced adipocyte differentiation, indicating CTCF is indispensable for adipogenesis. Intriguingly, combined analysis of Chip-seq data of these two TFs showed that ATF4 co-localized with CTCF in the promoters of key adipogenic genes including Cebpd and PPARg and co-regulated their transactivation. BI-3406 molecular weight Moreover, ATF4 directly regulated CTCF expression and interacted with CTCF in differentiated 3T3-L1 cells. In vivo, downregulation of ATF4 suppressed the expression of CTCF, Cebpd, and PPARg, leading to reduced adipose tissue expansion in refeeding mice. Consistently, mRNA expression of ATF4 and CTCF was positively correlated with each other in human subcutaneous adipose tissue and inversely associated with BMI, indicating a possible involvement of these two TFs in adipose development. Taken together, our data propose for the first time that ATF4 and CTCF work cooperatively to control adipogenesis and adipose development via orchestrating transcription of adipogenic genes. Our findings reveal novel therapeutic targets in obesity treatment.
Dosimetry is of high importance for optimization of patient-individual PSMA-targeted radioligand therapy (PSMA-RLT). The aim of our study was to evaluate and compare the feasibility of different approaches of image-based absorbed dose estimation in terms of accuracy and effort in clinical routine.

Whole-body planar images and SPECT/CT images were acquired from 24 patients and 65 cycles at 24h, 48h, and ≥96h after administration of a mean activity of 6.4 GBq [
Lu]Lu-PSMA-617 (range 3-10.9 GBq). Dosimetry was performed by use of the following approaches 2D planar-based dosimetry, 3D SPECT/CT-based dosimetry, and hybrid dosimetry combining 2D and 3D data. Absorbed doses were calculated according to IDAC 2.1 for the kidneys, the liver, the salivary glands, and bone metastases.

Mean absorbed doses estimated by 3D dosimetry (the reference method) were 0.54 ± 0.28 Gy/GBq for the kidneys, 0.10 ± 0.05 Gy/GBq for the liver, 0.81 ± 0.34 Gy/GBq for the parotid gland, 0.72 ± 0.39 Gy/GBq for the submandibular gland, and 1.68 ± 1.32 Gy/GBq for bone metastases. Absorbed doses of normal organs estimated by hybrid dosimetry showed small, non-significant differences (median up to 4.0%) to the results of 3D dosimetry. Using 2D dosimetry, in contrast, significant differences (median up to 10.9%) were observed. Regarding bone metastases, small, but significant differences (median up to 7.0%) of absorbed dose were found for both, 2D dosimetry and hybrid dosimetry. Bland-Altman analysis revealed high agreement between hybrid dosimetry and 3D dosimetry for normal organs and bone metastases, but substantial differences between 2D dosimetry and 3D dosimetry.

Hybrid dosimetry provides high accuracy in estimation of absorbed dose in comparison to 3D dosimetry for all important organs and is therefore feasible for use in individualized PSMA-RLT.
