A Systematic Review On The Effects Of Mirror Exposure On Behaviour and Obese Individuals

[Posted 23/Aug/2022]

AUDIENCE: Nursing

KEY FINDINGS: Mirror exposure can influence behaviour modification in obese patients. Therefore, the use of mirrors should be considered as an adjunct therapy in this group of patients.

BACKGROUND: Purpose of this study was to review the literature regarding the effects of mirror exposure on behaviour and obese patients. The review explored how mirror exposure influences behaviour in obese patients in terms of activity level, psychology and eating habits.

DETAILS: Obesity is a major epidemic that affects people worldwide but is more predominant in the Western world. Many health issues are directly linked to obesity, and current therapies have failed to provide a sustainable resolution to this problem. Mirror exposure has been used in eating disorders such as anorexia nervosa, bulimia and binge eating; however, there exists a gap in the use of mirrors in obese patients. The literature review focuses on the effects of mirror exposure on behaviour and obese patients. Literature that explicitly discussed mirror exposure in obese patients was included; five research articles were reviewed.

KEY FINDINGS: Offering HPV self-sampling as an additional screening option substantially increased cervical cancer screening participation and high-risk HPV detection compared with clinician sampling alone in this Singapore primary care population. The benefit was particularly relevant to women who had never previously undergone screening, suggesting that providing greater choice and convenience may help reach populations that are otherwise difficult to engage. More than half of screened women in the intervention group selected self-sampling, indicating substantial acceptance of this approach. However, lower uptake among women with less educational attainment highlights the need for targeted education and engagement strategies when implementing self-sampling programs.

BACKGROUND: Cervical cancer screening remains suboptimal in Singapore, where clinician-collected HPV testing has been the standard approach. Concerns related to discomfort, privacy, embarrassment, or the clinical setting may discourage some women from participating in screening. This pragmatic randomized controlled trial evaluated whether offering self-sampling for HPV DNA testing alongside clinician sampling could increase cervical cancer screening uptake and detection of high-risk human papillomavirus (HPV) compared with clinician sampling alone.

DETAILS: The open-label, 2-arm randomized controlled trial used a Zelen design and was conducted across National Healthcare Group Polyclinics in Singapore. Women aged 30-69 years who were due for cervical cancer screening were randomly assigned 1:1 to an intervention group or usual care. Women in the intervention group were offered clinician sampling followed by self-sampling if they did not choose clinician sampling, whereas women receiving usual care were offered clinician sampling alone. The primary outcome was detection of high-risk HPV DNA, with screening uptake as the secondary outcome.

Between August 2024 and February 2025, 650 women were randomized, with 640 participants included in the final analysis, 320 in each group. Subgroup analyses evaluated outcomes according to previous screening history, while multivariable analyses examined factors associated with screening choices.

High-risk HPV detection was significantly greater when self-sampling was offered alongside clinician sampling than with clinician sampling alone: 3.1% versus 0.3%, respectively, representing an absolute difference of 2.8% (95% CI, 0.8-4.8; P<.001). The higher detection rate was driven by greater screening participation, with screening uptake reaching 56.6% in the intervention group compared with 42.8% with usual care, an absolute difference of 13.8% (95% CI, 6.0-21.4; P<.001).

The increase in screening uptake was particularly evident among women who had no previous screening and those with a regular screening history. Among women who underwent screening in the intervention group, 56.4% selected self-sampling. Lower educational attainment was associated with lower odds of choosing self-sampling rather than declining screening altogether.

KEY FINDINGS: In adolescent and young women with classic 21OHD, combined OC containing 0.03 mg ethinylestradiol and 0.15 mg levonorgestrel was associated with broad reductions in circulating and urinary androgen-related steroids and an increase in cortisol levels. Nearly half of the participants who completed the study required a reduction in hydrocortisone dosage during the six-OC-cycle observation period. These findings suggest that combined OCs may provide an adjunctive approach for managing persistent androgen excess in females with classic CAH when conventional glucocorticoid treatment does not provide satisfactory biochemical control. However, the study was small and observational, so the findings do not establish a causal relationship, and randomized studies are needed to determine the longer-term clinical and metabolic effects of OC therapy in this population.

BACKGROUND: Androgen excess remains a therapeutic challenge in adolescent and young women with classic 21-hydroxylase deficiency (21OHD), the most common form of congenital adrenal hyperplasia (CAH). Combined oral contraceptives (OCs) containing ethinylestradiol and a progestin can influence ovarian and adrenal steroidogenesis, but their effects on the broader steroid profile in women with classic 21OHD have not been systematically characterized. This prospective observational study evaluated changes in circulating and urinary steroid metabolites following initiation of a combined OC in adolescent and young women with classic 21OHD.

DETAILS: The multicenter study enrolled 20 young women with genetically confirmed classic 21OHD between March 2021 and March 2024. Participants were 13-25 years old at baseline sampling, although the recruited cohort had a median age of 16 years and a range of 11-24 years. The participants initiated a combined OC containing 0.03 mg ethinylestradiol and 0.15 mg levonorgestrel. The study included three assessments: before OC initiation, during the third OC cycle, and during the sixth OC cycle. Blood samples and 24-hour urine collections were obtained at each visit, with plasma steroids measured using liquid chromatography-mass spectrometry and urinary metabolites assessed using gas chromatography-mass spectrometry. Seventeen of the 20 participants completed the study, with a median age of 16.8 years (range, 11-24). The reasons for OC initiation included irregular menses, contraception, amenorrhea, dysmenorrhea, and hyperandrogenemia. Most participants were receiving hydrocortisone and fludrocortisone for CAH management. The prospective design and combined assessment of plasma and urinary steroid profiles allowed detailed characterization of biochemical changes during OC treatment.

Combined OC therapy was associated with significant reductions in several circulating androgens and androgen precursors. Compared with baseline, plasma concentrations of 17α-hydroxyprogesterone, androstenedione, dehydroepiandrosterone, and testosterone decreased significantly, with all P values <0.005. Plasma cortisol concentrations increased significantly (P<0.001), while urinary 24-hour excretion of androgen metabolites, including the 11-oxygenated androgen metabolite 11-oxo-etiocholanolone, also declined.

The broader steroid analysis showed reductions in multiple androgen-related metabolites, including androsterone, etiocholanolone, DHEA, testosterone, dihydrotestosterone, 11-oxo-etiocholanolone, and 11β-hydroxyandrosterone. Cortisol concentrations and urinary cortisol excretion increased during OC treatment. These biochemical changes had implications for glucocorticoid management: 8 of 17 participants (47%) who completed the study had at least one reduction in hydrocortisone dose during follow-up in response to laboratory changes.

KEY FINDINGS: Computational facial phenotyping using GestaltMatcher identified MWS as the leading diagnosis in a child with a suspected de novo ZEB2 variant and provided quantitative evidence that supported variant interpretation. Three of 4 facial images reached the PP4 moderate threshold, while 1 reached the supporting threshold. Integration of facial phenotype, HPO information, and molecular data through PEDIA ranked ZEB2 first and contributed to classification of the variant as likely pathogenic. The findings provide a proof of concept for incorporating NGP into rare-disease diagnostic and variant-interpretation workflows, although larger, multicenter studies are needed to establish reproducibility and generalizability.

BACKGROUND: Mowat-Wilson syndrome (MWS) is a rare neurodevelopmental disorder caused by pathogenic variants in the ZEB2 gene and characterized by developmental impairment, epilepsy, congenital anomalies, and distinctive craniofacial features. Although next-generation phenotyping (NGP) tools such as GestaltMatcher can assist in recognizing rare genetic disorders, their use as quantitative evidence for variant interpretation within the American College of Medical Genetics and Genomics (ACMG) framework remains less established. This study evaluated whether computational facial phenotyping and multimodal clinical data could support variant prioritization and the ACMG PP4 phenotype-specificity criterion in MWS.

DETAILS: The investigators applied GestaltMatcher to a 4-year-old child with an undiagnosed neurodevelopmental disorder, suspected MWS, and a de novo ZEB2 variant. Facial photographs were analyzed alongside Human Phenotype Ontology (HPO) terms and simulated exome data using the PEDIA framework. Bayesian likelihood modeling was used to establish Gestalt score thresholds corresponding to supporting, moderate, strong, and very strong PP4 evidence. Brain MRI was also analyzed for structural abnormalities associated with MWS. The GestaltMatcher model had been trained using 9,671 images from 7,294 patients representing 275 disorders. For the MWS analysis, the dataset included 11 individuals with MWS and 14 age-matched controls.

GestaltMatcher ranked MWS as the leading diagnosis, while integration through PEDIA also ranked ZEB2 as the most likely disease-causing gene. Across the 4 facial images from the proband, 3 achieved the PP4 moderate threshold and 1 achieved the PP4 supporting threshold. The established Gestalt score thresholds were 0.5111 for supporting, 0.5672 for moderate, 0.6609 for strong, and 0.7632 for very strong evidence.

Using the NGP-derived PP4 moderate evidence together with the original ACMG evidence, the ZEB2 variant was classified as likely pathogenic. Brain MRI demonstrated subtle thinning of the corpus callosum, a finding consistent with previously reported MWS-associated neuroimaging abnormalities. MRI-derived features also differentiated individuals with MWS from age-matched controls in exploratory analysis.

An additional exploratory case involving an infant with molecularly confirmed MWS showed that GestaltMatcher could prioritize MWS based solely on infant facial characteristics. The authors emphasize that NGP is intended to complement, rather than replace, expert clinical genetic assessment.

A Nationwide Analysis

[Posted 26/Aug/2026]

AUDIENCE: Hospice & Palliative Nursing, Oncologys

KEY FINDINGS: Among adults with cancer approaching death, hospice utilization was associated with less frequent and lower-intensity broad-spectrum antibiotic exposure, particularly during the final days of life. The findings are consistent with a transition toward comfort-focused care, although they do not establish that hospice care itself caused the reduction. Hospice initiation occurred relatively close to death, with a mean interval of 39.9 days and a median of 22.0 days, and some antibiotic treatment may have preceded hospice enrollment. In addition, cancer stage, treatment status, infection severity, microbiological findings, functional status, symptom burden, and treatment intent were unavailable in the claims data.

BACKGROUND: Antibiotic treatment remains common during end-of-life care for patients with cancer, despite uncertain benefits for survival and potential burdens including drug toxicity, intravenous administration, adverse effects, and antimicrobial resistance. This retrospective cohort study evaluated whether hospice involvement was associated with differences in broad-spectrum antibiotic use among adults with cancer during the final 3 months of life.

DETAILS: Investigators analyzed Korean National Health Insurance Service claims data for adults aged ≥18 years who died between January 1, 2018, and December 31, 2021, with one of the 10 leading cancer-related causes of death. Hospice users had received inpatient, home-based, or consultation-based hospice care before death. Broad-spectrum antibiotic exposure included anti-pseudomonal penicillins, anti-pseudomonal cephalosporins, carbapenems, and glycopeptides. The final 90 days of life were divided into four intervals: 1–3 months before death, 1 week to 1 month before death, the final week, and the final 3 days. Antibiotic exposure was assessed by the proportion of patients receiving antibiotics and by days of therapy (DOT) per 1,000 patient-days. Propensity score matching was performed at a 1:2 ratio.

After matching, 38,102 hospice users and 75,736 non-hospice users were analyzed. During the final 3 months of life, 74.6% of hospice users and 79.0% of non-hospice users received at least one broad-spectrum antibiotic (P0.001). Antibiotic use was initially slightly higher among hospice users during the period 1–3 months before death, at 34.0% versus 32.2% (P0.001), but became consistently lower among hospice users thereafter. From 1 week to 1 month before death, use was 31.1% versus 32.8%; during the final week, 11.3% versus 18.5%; and during the final 3 days, 4.8% versus 10.3% among hospice and non-hospice users, respectively (all P0.001).

Days of therapy per 1,000 patient-days were also consistently lower among hospice users, with the greatest differences occurring during the final week and final 3 days of life. Carbapenems and glycopeptides demonstrated particularly pronounced differences between the groups. In cancer-specific analyses, patients with hematologic malignancies had the highest overall antibiotic exposure, followed by those with pancreatobiliary and gastric cancers, while exposure was comparatively lower among patients with breast and liver cancers.

A population-based cohort study in Sweden and Norway.

[Posted 17/Aug/2026]

AUDIENCE: Neurology, Psychiatry

KEY FINDINGS: In this large Nordic population-based cohort, paternal valproate monotherapy during spermatogenesis was not significantly associated with neurodevelopmental disorders in offspring compared with paternal lamotrigine or levetiracetam monotherapy. Findings were consistent across dose-response analyses and among fathers with epilepsy. The results do not support an increased neurodevelopmental risk from paternal valproate exposure, although limitations inherent to registry-based observational research remain.

BACKGROUND: Valproate is an effective antiseizure medication, but its established teratogenic effects with maternal exposure have led to regulatory restrictions for women of reproductive potential. Concerns about possible paternal effects on offspring neurodevelopment have also prompted precautionary recommendations for men. This study evaluated whether paternal valproate use during spermatogenesis was associated with neurodevelopmental disorders (NDDs) in offspring.

DETAILS: This population-based cohort study used nationwide Swedish and Norwegian health registries. It included singleton live births at >=22 completed gestational weeks between 1 January 2007 and 31 December 2020 in Sweden and between 1 January 2010 and 31 December 2018 in Norway. After exclusions, 4681 children in Sweden and 1572 children in Norway were included for analysis.

The analysis compared children whose fathers received valproate monotherapy during spermatogenesis with children whose fathers received lamotrigine or levetiracetam monotherapy. Outcomes included NDDs, attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), intellectual disability (ID), and disorders of psychological development. Analyses were adjusted for relevant parental and child characteristics, including parental age, psychiatric diagnoses, psychotropic medication use, epilepsy diagnosis, and, in Sweden, parental education and maternal cohabitation/marital status.

The study specifically examined paternal antiseizure medication exposure during spermatogenesis, corresponding to the approximately 3 months before conception. Dose-response analyses and analyses restricted to fathers with epilepsy were also conducted.

Among the children included in the primary comparison, 2051 were born to fathers who used valproate monotherapy during spermatogenesis. No significant association was identified between paternal valproate exposure and NDDs compared with paternal lamotrigine or levetiracetam exposure. The findings remained consistent in dose-response analyses and when the analysis was restricted to fathers with epilepsy.

During follow-up in Sweden, 406 children were diagnosed with an NDD, including 287 with ADHD, 140 with ASD, 55 with ID, and 79 with disorders of psychological development. In Norway, 60 children were diagnosed with an NDD, including 35 with ADHD, 13 with ASD, 5 with ID, and 26 with disorders of psychological development.

For ASD, the pooled adjusted hazard ratio was 1.29 (95% CI 0.89 to 1.85). The study authors noted that point estimates were slightly above 1.0 in some analyses but did not reach statistical significance.
