'Failed' contraception in a rural South African population
Objective. To investigate whether the free availability of contraception affects the need for termination of pregnancy (TOP).Design. Case-control study.Setting. South African rural hospitaLPopulation. Three thousand and ninety-five TOP seekers and 439 non-pregnant controls.Methods. Structured questionnaire followed by ultrasonography.Main outcome measures. Current use or recent discontinuation of contraception and the reason for discontinuation.Results. Less than one-third (28.6%) of TOP seekers claimed to be using contraception versus 85.0% of controls. Injectable contraception (IC)was preferred by the controls and oral contraception (OC) by TOP seekers (x2 = 48.5, p < 0.0001, OR 0.34 (95% confidence interval 0.25, 0.46)). The percentage of discontinuation of hormonal contraception was higher in controls (x2 = 6.3, p = 0.012, OR 0.51 (0.31, 0.85)). The reason for discontinuation of hormonal contraception was obtained from 31.2% of TOP seekers and 63.3% of controls; no reason for discontinuation was acknowledged by 30.1% of the former and 6.3% of the latter (x2 = 33.4, p < 0.0001, OR 6.40 (3.25, 12.56)). Side-effects of hormonal contraception prompted more discontinuation in the failed-contraception group (x2 = 120.5, p < 0.0001, OR 49.4 (21.6, 112.5)). Poor compliance and absence of an acknowledged reason for discontinuing hormonal contraception resulted in 173 unwanted pregnancies. Conclusion. In South Africa two main components of women's reproductive health and rights are freely available, namely contraception and TOP. Not using contraception is one of the main causes of unwanted pregnancy. Better education of both service providers and users is needed to improve use, compliance and perseverance with contraception

Prognostic implications of mean nuclear diameter in breast cancer.
The mean nuclear diameter of 100 breast cancers was measured on tissue sections, to evaluate its importance for early prognosis. The cases were subdivided into 3 subgroups: small (25.5% of cases), medium (63.3%) and large (11.2%) nuclei. Early recurrence and mortality rates were investigated in each of the categories. Increasing nuclear size was shown to be related to mortality from metastatic disease. However, large-nucleus tumours had an inverse relationship with lymphnode involvement and possibly with recurrence rate. Hence, in our material nuclear size as a sole criterion was not a good indicator of the early behaviour of operable breast cancer
The Future of Dancefloors: Building More Flexible, Open and Innovative Clubbing Experiences
Nightclubs across the world are in a state of crisis due to COVID-19, and neither inaction or ‘business as usual’ are viable options if the industry is to survive it.
It has never been more important to question, innovate and re-imagine the status quo
Attending school after treatment for a brain tumor: Experiences of children and key figures
Reintegration into school is a milestone for childhood brain tumor survivors, as well as for their parents, teachers, and healthcare providers. We explored their experiences following the school re-entry by conducting semi-structured interviews. Thematic analysis resulted in four main themes: "school performance," "psychosocial well-being," "support and approach," and "communication and collaboration." Children were pleased to return to school despite confrontation with adverse outcomes. Parents, teachers, and healthcare providers identified current and future concerns and challenges, as well as opportunities for academic and personal development. Their experiences highlight the importance of coordinated and systematic follow-up in close collaboration with healthcare providers

Nasopharyngeal microbiota in children is associated with severe asthma exacerbations
Background: The respiratory microbiome has been associated with the etiology and disease course of asthma. Objective: We sought to assess the nasopharyngeal microbiota in children with a severe asthma exacerbation and their associations with medication, air quality, and viral infection. Methods: A cross-sectional study was performed among children aged 2 to 18 years admitted to the medium care unit (MCU; n = 84) or intensive care unit (ICU; n = 78) with an asthma exacerbation. For case-control analyses, we matched all cases aged 2 to 6 years (n = 87) to controls in a 1:2 ratio. Controls were participants of either a prospective case-control study or a longitudinal birth cohort (n = 182). The nasopharyngeal microbiota was characterized by 16S-rRNA-gene sequencing. Results: Cases showed higher Shannon diversity index (ICU and MCU combined; P = .002) and a distinct microbial community composition when compared with controls (permutational multivariate ANOVA R2 = 1.9%; P < .001). We observed significantly higher abundance of Staphylococcus and “oral” taxa, including Neisseria, Veillonella, and Streptococcus spp. and a lower abundance of Dolosigranulum pigrum, Corynebacterium, and Moraxella spp. (MaAsLin2; q < 0.25) in cases versus controls. Furthermore, Neisseria abundance was associated with more severe disease (ICU vs MCU MaAslin2, P = .03; q = 0.30). Neisseria spp. abundance was also related with fine particulate matter exposure, whereas Haemophilus and Streptococcus abundances were related with recent inhaled corticosteroid use. We observed no correlations with viral infection. Conclusions: Our results demonstrate that children admitted with asthma exacerbations harbor a microbiome characterized by overgrowth of Staphylococcus and “oral” microbes and an underrepresentation of beneficial niche-appropriate commensals. Several of these associations may be explained by (environmental or medical) exposures, although cause-consequence relationships remain unclear and require further investigations.</p
