The levonorgestrel-releasing intrauterine system: an updated review of the contraceptive and noncontraceptive uses

The levonorgestrel containing intrauterine system is an effective and safe form of long-term yet reversible birth control. Intrauterine contraception use in the United States fell dramatically after early studies reported an association between intrauterine contraception use and later tubal infertility. Subsequent evaluation suggests that these early studies were biased. Users often experience menstrual disturbances. Informing patients of these common side effects is important to improve compliance. In addition to its contraceptive effect, the levonorgestrel intrauterine system offers potential therapeutic benefits in other clinical contexts, including menorrhagia, symptomatic fibroids, endometriosis, and endometrial suppression.     

A standardised ultrasonic diagnosis and an accurate prevalence for the retroverted uterus in general gynaecology patients

Transvaginal ultrasound with an empty bladder is recommended as a standardised ultrasonic technique for the accurate diagnosis of the retroverted uterus. Using this method, the prevalence of the retroverted uterus in 480 general gynaecological patients attending for subspecialist gynaecological ultrasound was 18%. The anteverting effect of the full bladder required for transabdominal ultrasound reduces the prevalence of the retroverted uterus to 13% (P < 0.001).     

Adolescents' views of and preferences for sexual and reproductive health services in Burkina Faso, Ghana, Malawi and Uganda

Adolescents' views of and preferences for sexual and reproductive health services highlight promising directions and persistent challenges in preventing pregnancy and HIV and treating sexually-transmitted infections (STIs) in this population. Results from nationally-representative surveys of 12-19 year-olds in Burkina Faso, Ghana, Malawi and Uganda in 2004 show that contraceptive and STI services and HIV testing are still under-utilized. A substantial proportion of sexually-active adolescents do not know of any source to obtain contraception or get STI treatment, and social-psychological reasons (e.g., embarrassment or fear) and financial cost remain common barriers to getting services. Adolescents' preferences are overwhelmingly for public clinics, with strongly positive perceptions of confidentiality, accessibility and cost. Some gender and country differences exist, yet overall females and males' views are similar. Results highlight the need to inform youth about sources, increase availability of government health facilities and improve youth's access to them, especially by reducing social barriers.     

Gut Microbiota Markers and Dietary Habits Associated with Extreme Longevity in Healthy Sardinian Centenarians

This study was aimed at characterizing the gut microbiota (GM) and its functional profile in two groups of Sardinian subjects with a long healthy life expectancy, overall named Long-Lived Subjects (LLS) [17 centenarians (CENT) and 29 nonagenarians (NON)] by comparing them to 46 healthy younger controls (CTLs). In addition, the contribution of genetics and environmental factors to the GM phenotype was assessed by comparing a subgroup of seven centenarian parents (CPAR) with a paired cohort of centenarians’ offspring (COFF). The analysis was performed through Next Generation Sequencing (NGS) of the V3 and V4 hypervariable region of the 16S rRNA gene on the MiSeq Illumina platform. The Verrucomicrobia phylum was identified as the main biomarker in CENT, together with its members Verrucomicrobiaceae, Akkermansia and Akkermansia muciniphila. In NON, the strongest associations concern Actinobacteria phylum, Bifidobacteriaceae and Bifidobacterium, while in CTLs were related to the Bacteroidetes phylum, Bacteroidaceae, Bacteroides and Bacteroides spp. Intestinal microbiota of CPAR and COFF did not differ significantly from each other. Significant correlations between bacterial taxa and clinical and lifestyle data, especially with Mediterranean diet adherence, were observed. We observed a harmonically balanced intestinal community structure in which the increase in taxa associated with intestinal health would limit and counteract the action of potentially pathogenic bacterial species in centenarians. The GM of long-lived individuals showed an intrinsic ability to adapt to changing environmental conditions, as confirmed by functional analysis. The GM analysis of centenarians’ offspring suggest that genetics and environmental factors act synergistically as a multifactorial cause in the modulation of GM towards a phenotype similar to that of centenarians, although these findings need to be confirmed by larger study cohorts and by prospective studies.     

Association between malocclusion and articulation of phonemes in early childhood

ObjectivesTo evaluate the relationship between dental malocclusion and speech to understand the etiology of speech sound disorders (SSD) in schoolchildren and to make a correct diagnosis and treatment plan.Materials and MethodsArticulation and dental occlusion, oromyofunctional evaluation with orofacial praxis and musculature, resting tongue position, and swallowing pattern were analyzed in 290 schoolchildren between the ages of 4 and 7 years. Statistical tests were considered significant for P < .05.ResultsA significant association between dental malocclusions (Angle Class II and III, anterior open bite, edge-to-edge bite, overjet and anterior crossbite) and phonetic alterations (P = .008) was observed. Sigmatisms and rhotacisms were the most frequent disorders. Malocclusions also showed a significant association with oral habits and with orofacial praxis and muscle activity.ConclusionsThe presence of malocclusion can cause imbalances in the functions involved in the stomatognathic system. Awareness of this relationship in young children would help professionals to implement preventive measures for the optimum development of children''s oral health.     

Positioning the six‐month review in the recovery process post‐stroke: The ideology of personal responsibility

Stroke is the UK's fourth highest cause of death and an estimated 300,000 people in England are living with related disability. This paper explores the six‐month review (6MR), a policy initiative that aimed to ameliorate unmet need. A multiple case study approach underpinned by critical realism was used to elicit the views of patients, carers, providers and commissioners across three sites using interviews, observations and documentation. Forty‐six patients (age range 28–91 years), 30 carers and 28 professionals were interviewed between December 2015 and October 2016. Twenty‐nine reviews were observed. Data was analysed thematically across sites. 6MRs carried out by stroke nurse specialists (SNSs) were found to be more medically orientated than those completed by a Stroke Association (SA) co‐ordinator who focused on social issues. Reviewers regarded reviews primarily as an opportunity to address unmet need and signpost to further services. Patients responded in three different ways: proactive and engaged, reflected an active orientation to recovery and self‐management; proactive and self‐managing on their own terms, encompassed patients who were striving for independence but took their own approach sometimes at odds with that of clinicians; and passive orientation, whereby patients did not engage in rehabilitation or self‐management. Patients identified different priorities to those of reviewers, particularly those with other long‐term conditions and this appeared to contribute to the dissatisfaction that some expressed. In conclusion, there was little evidence that the 6MR played a key role in recovery. Locally defined outcomes for the 6MR reflecting national policy were not substantiated by the findings. Our findings suggest that the 6MR should review therapy goals and facilitate patient‐led goals. Reviewers should be allowed the freedom to individualise the process rather than adhering to a rigid framework dictated by national policy and local protocols.     

Determinants of Acceptance of Weight Management Applications in Overweight and Obese Individuals: Using an Extended Unified Theory of Acceptance and Use of Technology Model

Overweight and obesity carry a tremendous burden in terms of physiological and psychological comorbidities. There is a great variety of weight management applications to support weight reduction, but a systematical analysis of individuals’ needs and requirements to adopt sustaining lifestyle changes is missing so far. This study aimed to assess the acceptance of such applications and its underlying predictors in individuals with overweight/obesity. A cross-sectional study was conducted, including 439 overweight/obese individuals. Health-related internet use and acceptance of weight management applications were examined using a modified questionnaire based on the Unified Theory of Acceptance and Use of Technology (UTAUT). The general acceptance of weight management applications was high, with significant age differences. Compared to older individuals, younger ones showed a higher acceptance. BMI was not significantly associated with acceptance. Besides psychometric data and eHealth-related data, performance expectancy, effort expectancy, and social influence proved to be significant predictors for acceptance. The total variance explanation provided by the extended UTAUT model was 61.2%. The knowledge of the influencing factors on acceptance might be useful in developing, optimizing, and establishing weight management applications. For determining acceptance and its predictors of weight management applications, the UTAUT model is a valid approach.     

Evidence-Based Nutrition Interventions Improved Adolescents’ Knowledge and Behaviors in Indonesia

Adolescence is a nutritionally vulnerable and critical life stage. However, few programs and policies focus on improving adolescent nutrition in Indonesia. To address this gap, we implemented a gender-responsive package of interventions: (1) breakfast and weekly iron-folic acid supplementation (WIFS), (2) a school-based nutrition education program, and (3) a social behavior change communication strategy. We surveyed 514 adolescents at baseline (2019) and endline (2020) in Klaten and Lombok Barat districts in Indonesia. The survey included a knowledge assessment on nutrition, as well as indicators of attitudes and behaviors on diet, physical activity, and WIFS. We employed multivariable linear and logistic regression to test for pre–post intervention differences. Overall knowledge was significantly higher post-intervention (β: 3.3; 95% confidence interval [CI]: 2.6, 3.9). Diet diversity was high at both timepoints, however, at post-intervention there was significantly higher odds of consuming vitamin A-rich fruits and vegetables (Odds Ratio [OR]: 1.5; 95% CI: 1.1, 2.0) and lower odds of consuming sugar-sweetened beverages (OR: 0.4; 95% CI: 0.3, 0.5). Post-intervention, there was higher odds of reporting 60 min of daily physical activity (OR: 2.3; 95% CI: 1.7, 3.2) and WIFS among girls (OR: 6.7; 95% CI: 1.5, 30.9). The package of interventions may be a promising first step to improving adolescent nutrition in Indonesia.     

The Pre-Analytical CEN/TS Standard for Microbiome Diagnostics—How Can Research and Development Benefit?

Recently, CEN/TS 17626:2021, the European pre-analytical standard for human specimens intended for microbiome DNA analysis, was published. Although this standard relates to diagnostic procedures for microbiome analysis and is relevant for in vitro diagnostic (IVD) manufacturers and diagnostic laboratories, it also has implications for research and development (R&D). We present here why standards are needed in biomedical research, what pre-analytical standards can accomplish, and which elements of the pre-analytical workflow they cover. The benefits of standardization for the generation of FAIR (findable, accessible, interoperable, reusable) data and to support innovation are briefly discussed.
