Background Various observations have suggested that the course of COVID-19 might be less favourable in patients with inflammatory rheumatic and musculoskeletal diseases receiving rituximab compared with those not receiving rituximab. We aimed to investigate whether treatment with rituximab is associated with severe COVID-19 outcomes in patients with inflammatory rheumatic and musculoskeletal diseases.Methods In this cohort study, we analysed data from the French RMD COVID-19 cohort, which included patients aged 18 years or older with inflammatory rheumatic and musculoskeletal diseases and highly suspected or confirmed COVID-19. The primary endpoint was the severity of COVID-19 in patients treated with rituximab (rituximab group) compared with patients who did not receive rituximab (no rituximab group). Severe disease was defined as that requiring admission to an intensive care unit or leading to death. Secondary objectives were to analyse deaths and duration of hospital stay. The inverse probability of treatment weighting propensity score method was used to adjust for potential confounding factors (age, sex, arterial hypertension, diabetes, smoking status, body-mass index, interstitial lung disease, cardiovascular diseases, cancer, corticosteroid use, chronic renal failure, and the underlying disease [rheumatoid arthritis vs others]). Odds ratios and hazard ratios and their 95% CIs were calculated as effect size, by dividing the two population mean differences by their SD. This study is registered with ClinicalTrials.gov, NCT04353609.

Background Kinshasa is Africa's third largest city and one of the continent's most rapidly growing urban areas. PMA2020 data showed that Kinshasa has a modern contraceptive prevalence of 26.5% among married women in 2018. In Kinshasa's method mix, the contraceptive implant recently became the dominant method among contraceptive users married and in union. This study provides insight into patterns of implant use in a high-fertility setting by evaluating the 24-month continuation rate for Implanon NXT and identifying the characteristics associated with discontinuation. Methodology This community-based, prospective cohort study followed 531 Implanon users aged 18-49 years at 6, 12 and 24 months. The following information was collected: socio-demographic characteristics, Method Information Index (MII) and contraceptive history. The main outcome variable for this study was implant discontinuation. The incidence rate of discontinuation is presented as events per 1000 person/months (p-m), from the date of enrolment. The Cox proportional hazards modelling was used to measure predictors of discontinuation. Results A total of 9158.13 p-m were available for analysis, with an overall incidence rate of 9.06 (95% CI: 9.04-9.08) removals per 1000 p-m. Of nine possible co-variates tested, the likelihood of discontinuation was higher among women who lived in military camps, had less than three children, never used injectables or implants in the past, had experienced heavy/ prolonged bleeding, and whose MII score was less than 3.

Emergency contraceptive pills have the potential to address gaps in the family planning method mix in the DRC. Assessing whether women have incomplete or erroneous information about family planning methods can provide better understanding of women's contraceptive choices in low-income countries.

ObjectivesGiven the promise of DMPA-SC to increase community-level access to modern contraception in developing countries, we conducted an observational study to assess the acceptability and feasibility of DMPA-SC self-injection among women in Kinshasa, Democratic Republic of the Congo, and of medical/nursing (M/N) students as instructors for self-injection.Study designWomen who selected DMPA-SC at a community outreach event adjacent to a health center were interviewed upon acceptance (baseline) and then 3, 6 and 12 months later.ResultsOf 850 clients selecting DMPA-SC at baseline, 640 (75.3%) opted for self-injection over being injected by the M/N students for reasons of convenience and personal agency. Among these 640 self-injectors, 47.5% were anxious at baseline (for fear of needles or injecting incorrectly). Over 80% reported feeling very ready after training, confident that they knew how to self-inject and confident that they would remember the next injection date. By 3 months, 97% described it as easy. Half (54%) experienced side effects, mainly menstrual irregularities, the main reason for discontinuation. At 6-month follow-up, self-injectors cited effectiveness and ease of use as positive elements, though one quarter reported side effects. Their impressions of M/N students as instructors were highly positive.ConclusionsWhere DMPA-SC was free and easily accessible, the majority of women interested in DMPA-SC opted to learn self-injection. The M/N students performed well in instructing women to self-inject. Clients were highly satisfied with the services received, yet many did not recognize their student status, possibly because outreach occurred near a health facility. Once told, clients remained very favorable, suggesting strong motivation to receive their preferred contraceptive free, whoever the provider.Implication statementThis study provides additional evidence on the acceptability and the feasibility of the self-injection of DMPA-SC by users from a resource-limited setting.

Background Non-communicable disease (NCD) multimorbidity is associated with impaired functioning, lower quality of life and higher mortality. Susceptibility to accumulation of multiple NCDs is rooted in social, economic and cultural contexts, with important differences in the burden, patterns, and determinants of multimorbidity across settings. Despite high prevalence of individual NCDs within the Caribbean region, exploration of the social epidemiology of multimorbidity remains sparse. This study aimed to examine the social determinants of NCD multimorbidity in Jamaica, to better inform prevention and intervention strategies. Methods Latent class analysis (LCA) was used to examine social determinants of identified multimorbidity patterns in a sample of 2551 respondents aged 15–74 years, from the nationally representative Jamaica Health and Lifestyle Survey 2007/2008. Multimorbidity measurement was based on self-reported presence/absence of 11 chronic conditions. Selection of social determinants of health (SDH) was informed by the World Health Organization’s Commission on SDH framework. Multinomial logistic regression models were used to estimate the association between individual-level SDH and class membership. Results Approximately one-quarter of the sample (24.05%) were multimorbid. LCA revealed four distinct profiles: a Relatively Healthy class (52.70%), with a single or no morbidity; and three additional classes, characterized by varying degrees and patterns of multimorbidity, labelled Metabolic (30.88%), Vascular-Inflammatory (12.21%), and Respiratory (4.20%). Upon controlling for all SDH (Model 3), advancing age and recent healthcare visits remained significant predictors of all three multimorbidity patterns (p < 0.001). Private insurance coverage (relative risk ratio, RRR = 0.63; p < 0.01) and higher educational attainment (RRR = 0.73; p < 0.05) were associated with lower relative risk of belonging to the Metabolic class while being female was a significant independent predictor of Vascular-Inflammatory class membership (RRR = 2.54; p < 0.001). Material circumstances, namely housing conditions and features of the physical and neighbourhood environment, were not significant predictors of any multimorbidity class. Conclusion This study provides a nuanced understanding of the social patterning of multimorbidity in Jamaica, identifying biological, health system, and structural determinants as key factors associated with specific multimorbidity profiles. Future research using longitudinal designs would aid understanding of disease trajectories and clarify the role of SDH in mitigating risk of accumulation of diseases.

Honeybee colonies are increasingly exposed to environmental stress factors, which can lead to their decline or failure. However, there are major gaps in stressor risk assessment due to the difficulty of assessing the honeybee colony state and detecting abnormal events. Since stress factors usually induce a demographic disturbance in the colony (e.g. loss of foragers, early transition from nurse to forager state), we suggest that disturbances could be revealed indirectly by measuring the age- and task-related physiological state of bees, which can be referred to as biological age (an indicator of the changes in physiological state that occur throughout an individual lifespan). We therefore estimated the biological age of bees from the relationship between age and biomarkers of task specialization (vitellogenin and the adipokinetic hormone receptor). This relationship was determined from a calibrated sample set of known-age bees and mathematically modelled for biological age prediction. Then, we determined throughout the foraging season the evolution of the biological age of bees from colonies with low (conventional apiary) or high Varroa destructor infestation rates (organic apiary). We found that the biological age of bees from the conventional apiary progressively decreased from the spring (17 days) to the fall (6 days). However, in colonies from the organic apiary, the population aged from spring (13 days) to summer (18.5 days) and then rejuvenated in the fall (13 days) after Varroa treatment. Biological age was positively correlated with the amount of brood (open and closed cells) in the apiary with low Varroa pressure, and negatively correlated with Varroa infestation level in the apiary with high Varroa pressure. Altogether, these results show that the estimation of biological age is a useful and effective method for assessing colony demographic state and likely detrimental effects of stress factors.

ObjectivesThe objectives were to assess acceptors' attitudes toward Sayana® Press as a method and toward the mechanism of community-based distribution by medical and nursing (M/N) students, known locally as “DBCs,” in Kinshasa, Democratic Republic of the Congo, and to evaluate the experience of these DBCs.Study designIn 2015, surveys were conducted among (1) acceptors of Sayana® Press on the day of the initial injection, (2) these same acceptors 3 months later and (3) the DBCs providing community-based services. The analysis was descriptive and involved no significance testing.ResultsAcceptors of Sayana® Press expressed high levels of satisfaction with the method, despite some pain experienced at injection and subsequent side effects. Although most were satisfied with the counseling and services received from the DBCs, less than one third realized that the providers were M/N students. The DBCs expressed satisfaction in serving as community-based distributors; more than 95% would recommend it to others. Their primary complaints were lack of remuneration, stockouts and need for greater supervision.ConclusionsConsistent with results from previous pilot introductions of Sayana® Press in three African countries, clients were highly satisfied with Sayana® Press as a method. The reported preference for resupply at health centers may reflect a lack of client awareness that the DBCs administering methods near the health center were not in fact staff from the health center. The pilot served to gain acceptance for the use of M/N students in community-based distribution, paving the way for additional task-shifting pilots in Kinshasa.ImplicationsSayana® Press represents a promising new method for increasing access to modern contraception in low-income countries. The Kinshasa experience is the first to test the use of medical and nursing students as providers at the community level. The study reports high levels of satisfaction on three counts: acceptors of the contraceptive method, acceptors of the mode of service delivery, and DBCs in their role as providers of contraception at the community level. However, many clients were not aware that the DBCs were students. The study represents an important contribution to the literature on task-shifting, especially in a country with chronic shortages of healthcare personnel.

Midterm process evaluation results indicated that design and implementation failures hindered the program's success, notably: (1) the short-acting methods provided by community-based distributors (CBDs) offered limited choice; (2) the nominal revenue retained from selling the methods provided limited motivation for the volunteer CBDs; and (3) the model was poorly coordinated with the existing clinical service system, partly because of challenging systems issues. In the revised model, the CBDs will also provide subcutaneous injectables and emergency contraceptive pills, retain more revenue from contraceptive sales, and have better interaction with the existing system including conducting monthly mini-campaigns to increase visibility and attract more clients.
