A decade of PrEP: the evolution of HIV pre-exposure prophylaxis content and sentiments in South African print news media, 2012-2021.

After nearly a decade of HIV pre-exposure prophylaxis (PrEP) rollout in sub-Saharan Africa, there has been limited study of PrEP messaging in news media. We selected twenty South African newspapers with the highest circulation volumes to retrieve articles published in 2012-2021 mentioning PrEP (N = 249). Using inductive content analysis, we developed a structured codebook to characterise PrEP-related content and sentiments, as well as their evolution over time, in the South African press. Many articles espoused favourable attitudes towards PrEP (52%), but a sizeable fraction espoused unfavourable attitudes (11%). Relative to PrEP-favourable articles, PrEP-unfavourable articles were significantly more likely to emphasise the drawbacks/consequences of PrEP use, including adherence/persistence requirements (52% vs. 24%, p = .007), cost (48% vs. 11%, p < .001), and risk compensation (52% vs. 5%, p < .001). Nevertheless, the presence of these drawbacks/consequences in print media largely declined over time. Key populations (e.g. adolescents, female sex workers) were frequently mentioned potential PrEP candidates. Despite message variations over time, prevention effectiveness and adherence/persistence requirements were the most widely cited PrEP benefits and drawbacks, respectively. Study findings demonstrate the dynamic nature of PrEP coverage in the South African press, likely in response to PrEP scale-up and real-world PrEP implementation during the study period.

Comparison of USG-Guided Supraclavicular Brachial Plexus Block by Single-Point Versus Multiple-Point Injection Technique: A Prospective Randomized Trial.

Background This study investigated the success rate of ultrasonography (USG)-guided supraclavicular block using a single-point injection technique comparing it with multiple-point injection technique, in terms of nerve sparing, time taken to perform the procedure, time taken to onset of sensory and motor block. Materials and methods A total of 204 patients of American Society of Anesthesiologists (ASA) Status I and II, aged 18-60 years, with body mass index (BMI) ≤30 kg/m2, posted for upper limb surgeries were given USG-guided supraclavicular brachial plexus block with 15 mL of 0.5% Ropivacaine. The patients were randomly divided into group A (single-point injection) and group B (multiple-point injection), using an out-of-plane technique. Sensory and motor block was assessed for onset and maximum grade achieved, by using pinprick, cold, touch, and movement respectively. The efficacy of the block was tested by assessment in the territories of musculocutaneous, ulnar, radial, median, axillary, and intercostobrachial nerves. Procedural time was calculated from the insertion of the needle till the complete injection of the drug. Results Patients in both groups were comparable in terms of demography and ASA status. The success rate for group A was 60.8%, compared to 98% in group B. In group B, the intercostobrachial nerve was most commonly spared (7.84%), followed by ulnar (1.96%), and radial (0.98%). On the other hand, in group A, the most frequently spared nerves were ulnar and intercostobrachial (23.5% each), followed by radial (12.7%), axillary (10.8%), musculocutaneous (7.8%), and median nerves (6.9%). The onset of sensory and motor block was similar in both groups. The procedure time was longer in the multiple-point group. Conclusion Our observations suggest that nerve sparing is much lesser in the multiple-point injection technique used for USG-guided supraclavicular block. In a good number of patients using this technique, the intercostobrachial nerve gets blocked.

Psychiatric morbidity and substance use in migrant workers: A population based study.

BACKGROUND: The prevalence of mental health problems and substance abuse in the migrant population is higher than the general population. AIMS AND OBJECTIVES: To assess the prevalence and pattern of mental health issues and substance use in the migrant population and highlight the association with the reverse migration of migrant workers. METHODOLOGY: The field staff visited the shelter homes for migrant population in four cities of Northern India (Chandigarh (UT), Bhatinda (Punjab), Panchkula (Haryana) and Jaipur (Rajasthan). After maintaining the social distance and wearing masks by the staff and migrants, written informed consent was taken for participation in the study. The socio-demographic details of reverse migrants were noted down and Hindi version of Patient Health Questionnaire (PHQ-9) for mental health problems and screening tool for pattern of substance abuse was administered. Geographically matched undisplaced were also administered these tools. RESULTS: A total of 275 reverse migrants and 276 undisplaced were included in the study. The prevalence of ever use for all the substances among reverse migrants was 44.4% (122/275) and among undisplaced, it was 45.3%. The prevalence of alcohol, tobacco and cannabis was higher than the general population. The prevalence of at least one diagnosis on PHQ-9 is 13.45% (reverse migrants 19.3% and undisplaced 7.6) and the prevalence of other depressive disorder is significantly higher in reverse migrants (17.1%) than undisplaced (4.0%). CONCLUSION: The study concludes that prevalence of mental health issues and substance abuse in migrant population is significantly higher than the general population and the prevalence of at least one diagnosis and other depressive disorder is significantly higher in reverse migrants than undisplaced.

Factors Leading to Reverse Migration Among Migrant Workers During the COVID-19 Pandemic: A Multicenter Study From Northwest India.

OBJECTIVE: To examine the various psychosocial factors associated with reverse migration among migrant workers during the coronavirus disease 2019 (COVID-19) lockdown in India. METHODS: A cross-sectional multicenter study was conducted at 4 sites in Northwest India. The migrant workers were recruited from various shelter homes, and information was gathered from reverse migrant workers and controls using various tools including a sociodemographic profile; knowledge, attitudes, and practices questionnaire; and reasons for migration and reverse migration questionnaires. A total of 275 reverse migrant workers and 276 controls participated in the study. RESULTS: There was a considerable difference between reverse migrant workers and controls regarding the question of whether it was safe to travel during lockdown (76.0% vs 26.4%, respectively). The most common route of spread of COVID-19 infection was through touching and sneezing, and symptoms were fever, dry cough, and sore throat in both groups. Reverse migrant workers had low self-esteem and were reluctant to participate in customs of their migration city. A large number of reverse migrant workers reported that they had no money to survive, worried about family back home at their village, felt pressured by family members to come back to the village, and had been terminated from their job. CONCLUSIONS: Reverse migrant workers had the attitude that it was safe to travel during the lockdown. About one-fifth of the reverse migrant workers reported no place to live and fear of getting an infection. The reverse migrant workers also reported feeling low and gloomy, restless, and uncertain about the future and fear of death. Lack of jobs was a major factor driving migrant workers from their native homes.

Social Context of Adherence in an Open-Label 1 % Tenofovir Gel Trial: Gender Dynamics and Disclosure in KwaZulu-Natal, South Africa.

CAPRISA 008, an open-label extension study of tenofovir gel with coitally-related dosing, provided an opportunity to explore the relationship between product adherence and gender dynamics in a context where women knew they were receiving an active product with evidence of HIV prevention effectiveness. Interviews with 63 CAPRISA 008 participants and 13 male partners in KwaZulu-Natal, South Africa, highlighted that the process of negotiating gel use was determined in part by relationship dynamics including the duration of the relationship, the living situation, an evaluation of the relationship (e.g., partner intimacy and relationship expectations) and culturally-defined steps for formalizing the relationship. While disclosure facilitated adherence for many, others reported using the gel effectively with no disclosure, and in some situations disclosure was a barrier to adherence. Women should be supported in their choice about what to disclose and have opportunity to use this and similar products without their partners' knowledge or acquiescence.

A randomized controlled trial of motivational interviewing to prevent risk for an alcohol-exposed pregnancy in the Western Cape, South Africa.

AIM: To test the effectiveness of motivational interviewing (MI) to reduce the risk of an alcohol exposed pregnancy (AEP) in a high-risk population. DESIGN: Randomized controlled trial. SETTING: Rural population in the Western Cape, South Africa. PARTICIPANTS: A total of 165 women aged 18-44 years at risk of AEP. INTERVENTION: Five-session MI intervention. MEASUREMENTS: Structured questionnaires were administered pre-intervention and at 3 and 12 months follow-up. The primary outcome measure was AEP at 12 months. Secondary outcomes were AEP at 3 months, and alcohol use and effective contraception at 3 and 12 months. FINDINGS: There was a significant difference in the decline in the proportion of women at risk for an AEP in the MI group at 3 months (50 versus 24.59%; P = 0.004), maintained at 12 months (50.82 versus 28.12%; P = 0.009). In an intention-to-treat analysis these differences were also significant (32.93 versus 18.07%; P = 0.029; and 37.80 versus 21.69%; P = 0.024, respectively). The odds ratio for no longer being at risk of an AEP (MI versus control) at 12 months was 2.64 [95% confidence interval (CI): 1.18-5.94]. In the intention-to-treat analysis this ratio was 2.19 (95% CI: 1.05-4.65). CONCLUSIONS: A five-session motivational interviewing intervention was found to be effective with women at risk of an alcohol-exposed pregnancy, and could be implemented as part of routine primary care clinic services in similar populations. The message of 'no alcohol in pregnancy' should be adapted to include better family planning and early recognition of pregnancy.

Thalidomide: chemistry, therapeutic potential and oxidative stress induced teratogenicity.

Thalidomide and its one analogue, lenalidomide (CC5103 or revlimid) are recently approved for the treatment of multiple myeloma. Multiple myeloma is characterized by an overproduction of malignant plasma cells in the bone marrow. The journey of thalidomide was started in 1956 when it was marketed as a non-barbiturate sedative agent. It was considered as a "wonder drug" that provided safe and sound sleep and hence, used to cure morning sickness in pregnant women. Later, in 1961, it was withdrawn from the world market due to its serious side effects, i.e., teratogenic activity. However, the recent decade has witnessed a true renaissance in interest in its broad biological activity. In particular, thalidomide was reevaluated and attracted significant attention due to its selective inhibitory activity of tumor necrosis factor-α (TNF-α), which is a clinically important activity against serious diseases such as rheumatoid arthritis, Crohn's disease, leprosy, AIDS, and various cancers. The comeback of thalidomide to the legitimate status of a marketed drug came in 1998 when it received FDA approval for the treatment of erythema nodosum leprosum (ENL). Recently, the drug has got FDA approval for the treatment of multiple myeloma. In the last few years, number of thalidomide analogues have been synthesized and are in clinical development as a class of immunomodulatory drugs. Among these, lenalidomide is more potent than thalidomide, and is also non-neurotoxic. It was shown in vitro studies to induce apoptosis or arrest growth even in resistant multiple myeloma cell lines, decrease binding of the cells to bone marrow stromal cells, and stimulate host natural killer cell immunity. It also inhibits tumour growth and decreases angiogenesis. Earlier reviews have described the pharmacological aspects of thalidomide and a review has focused only on synthetic aspect of thalidomide. However, review focusing on chemistry and metabolism and mechanism of biological activity is still lacking. In this review, we will concisely describe the therapeutic aspects, metabolism and synthesis of thalidomide.
