Acute leukemia during reproductive life: its course, complications and sequelae for fertility.
Acute leukemia is less common during the reproductive years than in children or in post-menopausal women. Effective chemotherapy exists for adult lymphocytic leukemia, and the median survival is 18 to 20 months. Acute myelogenous leukemia still has a less favorable prognosis, with a medial survival of 12 months despite effective chemotherapeutic agents. The occurrence of acute leukemia in pregnancy does not change the overall prognosis, which depends primarily on the cytopathologic types. If leukemia occurs during the first trimester, therapeutic abortion is advised since the rate of spontaneous abortion after chemotherapy is high in the first trimester and fetal malformations are common. Acute leukemia can be treated in the second and third trimesters with little effect on the pregnancy or fetus. In patients cured of acute leukemia, the potential for subsequent pregnancies exists with little likelihood of increases in fetal malformations.

Career set: a resource through transitions and crises.
Following Foote the life histories of twenty-seven white, middle-aged, middle class, American mothers were analyzed for career-like components [4]. Motherhood dominates the lives of these women but is only one of several careers which ebb and flow throughout their lives. Treating careers as developmental subdivisions in the life course, we understand how women can progress through life transitions and crises. Properties of careers, such as the emergent symbols of success, the clockwork which sets the time limits for career objectives, and the bargaining which these women undertake to work out career conflicts, all contribute to the understanding of how career is placed beside career to create each woman's career set. The career set acts as a social and personal resource, providing consistent and continuous meaning throughout major periods of time even in the face of major career stress or loss.

Association of Socioeconomic Factors With Oral Health in Older Adults: A Systematic Review and Meta-Analysis.
BACKGROUND: Oral diseases remain disproportionately prevalent among older adults. However, evidence on oral health inequalities among older adults remains dispersed across studies that have used different socioeconomic indicators and oral health measures and has not been synthesised. OBJECTIVE: To synthesise the evidence on the association between socioeconomic factors and oral health among older adults aged 75 years and older. METHODS: A systematic review and meta-analysis was conducted following PRISMA guidelines. The Medline, Embase, and CENTRAL databases were searched. Studies reporting socioeconomic factors (education, income, occupation, area-level deprivation, and multi-aspect socioeconomic position) and oral health (dentition status, dental caries, periodontal disease, dry mouth, oral function, oral health behaviours, and oral health-related quality of life (OHRQoL)) among older adults were included. Risk of bias was assessed using the Newcastle-Ottawa Scale. RESULTS: Sixty-eight studies were included. Meta-analyses showed that socioeconomic disadvantage in older adults was associated with: (1) poor dentition status: fewer natural teeth, higher prevalence of edentulism, and lacking a functional dentition; (2) more teeth with decay; (3) irregular dental attendance; and (4) poorer OHRQoL. Similar patterns were generally observed for periodontal disease, dry mouth, and oral function, although no meta-analysis could be performed due to limited evidence and heterogeneous oral health measures. CONCLUSION: Socioeconomic disadvantage was consistently associated with poor oral health in older adults. Associations were more pronounced for dentition status, reflecting the cumulative socioeconomic disadvantage over the life course. Socioeconomic factors should be considered to inform prevention, clinical decision-making and oral healthcare planning for the ageing population.

Parental son preference in childhood and sex differences in the risk of cardiovascular disease in middle-aged and older adults.
INTRODUCTION: Sex differences in cardiovascular disease (CVD) risk are examined through biological and clinical factors, with less attention to early-life social exposures. This study examined associations of childhood parental son preference with CVD risk, sex differences, and mediation by modifiable risk factors. METHODS: This cohort analysis included China Health and Retirement Longitudinal Study participants aged ≥45 years without baseline CVD. Parental son preference was assessed retrospectively in 2014; incident CVD was self-reported physician-diagnosed heart disease or stroke through 2020. Sampling-weighted, community-clustered Cox models estimated adjusted hazard ratios (aHRs) and 95% CIs. Sex was prespecified as an effect modifier; mediation by 13 risk factors used inverse-odds-ratio weighting. Data were collected from 2011 to 2020 and analyzed from 2025 to 2026. RESULTS: Among 8,079 participants (mean age, 57.5 years; 4,216 women [52.2%]), 1,820 (22.5%) reported parental son preference. Son preference was associated with higher CVD risk overall (aHR 1.23 [95% CI 1.04, 1.46]) and among women (aHR 1.25 [95% CI 1.03, 1.53]); among men, the estimate was 1.16 (95% CI 0.87, 1.56), with limited heterogeneity by sex (ratio of aHRs 1.06 [95% CI 0.72, 1.58]). Among women, risk was concentrated in the highest paternal (aHR 1.47 [95% CI 1.14, 1.90]) and maternal (aHR 1.50 [95% CI 1.12, 1.99]) preference categories. Modifiable risk factors mediated 5.8% (95% CI 1.9%, 9.7%) of the association among women, mainly through socioeconomic and psychosocial factors. CVD risk was highest with both son preference and high risk-factor burden overall (aHR 1.97 [95% CI 1.43, 2.73]) and among women (aHR 2.23 [95% CI 1.61, 3.10]). CONCLUSIONS: Parental son preference was associated with higher incident CVD risk, with the largest estimates in the highest paternal or maternal categories among women. Modifiable risk factors explained a modest proportion, supporting life-course cardiovascular prevention that considers sex-differentiated childhood environments alongside risk-factor modification.

Adverse pregnancy outcomes and long-term cardiovascular disease risk.
Pregnancy provides a unique physiological stress test for the cardiovascular system, during which, adverse pregnancy outcomes (APOs) can unmask latent susceptibility to future disease. Common complications, including hypertensive disorders of pregnancy (HDP), gestational diabetes, and preterm birth (delivery before 37 weeks' gestation), identify women at substantially higher long-term risk of cardiovascular morbidity and mortality compared with women without a history of APOs. These excess risks likely reflect the combined effects of pre-existing cardiometabolic and genetic susceptibility, as well as the haemodynamic and metabolic stressors of pregnancy, heralding accelerated risk factor trajectories, relative impairment in endothelial and microvascular function, and early disease onset. This final Review in the Series extends the focus from cardiovascular disease during pregnancy and HDP to the long-term cardiovascular implications of APOs after delivery. We synthesise epidemiological data quantifying cardiovascular risk across major APO phenotypes and emerging evidence linking maternal APO history with cardiometabolic risk trajectories in offspring. We also delineate putative mechanistic pathways and summarise guidelines and consensus-informed recommendations for short-term and long-term follow-up after APOs. Finally, we propose practical approaches for integrating APO history into cardiovascular disease risk assessment and guideline-directed prevention across the female life course. We highlight key knowledge gaps, including uncertainty about optimal follow-up models, the limitations of current risk-stratification tools, and the absence of APO-specific prevention trials. We also outline priorities for mechanistic and implementation research. Positioning APOs as early, sex-specific indicators of cardiovascular risk offers a key window of opportunity to shift prevention upstream and improve cardiovascular health outcomes for women.

Modelling time-varying genetic effects on binary disease risk via functional Mendelian randomization.
MOTIVATION: Genome-wide association studies have identified thousands of genetic variants associated with complex traits, establishing Mendelian randomization (MR) as a powerful framework for causal inference using variants as natural experiments. However, existing MR methods treat causal effects as static, relying on cross-sectional exposure measurements and ignoring how genetic predispositions to disease operate dynamically across the life course. Recovering age-specific causal effect functions from longitudinal data requires combining functional data representations of exposure trajectories with instrumental variable estimation strategies suitable for binary disease endpoints, a methodological gap that has remained unaddressed. RESULTS: We develop a functional MR framework for binary outcomes that integrates functional principal component analysis with two-stage residual inclusion (2SRI), ensuring consistent estimation under the nonlinear logistic link function that renders standard instrumental variable estimators inconsistent. Simulations across different causal effect trajectory shapes, varying measurement densities, and varying instrument strengths demonstrate accurate recovery of time-varying genetically predicted effects with minimal bias. Applied to UK Biobank data, the framework identifies an age-specific causal effect of genetically predicted body mass index on type 2 diabetes risk concentrated in early mid-adulthood and progressively attenuating thereafter. Concordance between the proposed 2SRI estimator applied to type 2 diabetes and the established continuous-outcome functional MR estimator applied to the paired glycated haemoglobin marker in the same cohort provides indirect empirical support for the validity of the proposed approach. AVAILABILITY AND IMPLEMENTATION: The method is implemented in the R package mvfmr, with a full tutorial vignette.

The problems of generations: and generational analysis.
The focus of this paper is two fold: 1. conceptual and methodological problems underlying the life-span sociology literature that heretofore have not been discussed; and 2. application of the generational analysis model to the question of life cycle change in personal values. Specifically, we address the issues of whether (1) value change over the life course is a result of period shifts or individual maturation and (2) differences in values among age strata are a function of cohort experience or individual maturation (aging). Utilizing data from the Detroit Area Studies, four measures of values were constructed. The analyses shows that on only one of the four dependent measures was aging directly implicated in the findings. However, cohort differences and period effects were found to have a significant effect on the distribution of several of the value indices. The data are consistent with Mannheim's observation that older cohorts are affected by social change although the relative degree of observed change is much greater among the young.

Autism care: reimagining the spectrum.
Autism care policy is at a critical inflection point. Applied behavior analysis (ABA), long established as the "gold standard" through state insurance mandates in the US, has functioned as the default reimbursable intervention for autistic children. However, advances in genomics, neuroscience, developmental psychology, and scholarship on autistic lived experience have expanded understanding of autism as a heterogeneous neurotype characterized by meaningful differences in neural organization rather than a unitary disorder. Contemporary models emphasize neurodiversity, strengths-based perspectives, and the interaction between developmental processes and environmental contexts in shaping functional outcomes. Many autistic children also meet criteria for complex care needs, requiring coordinated, interdisciplinary services across health, educational, and community systems. This manuscript proposes reframing the "autism spectrum" from a hierarchy of symptom severity to a prevention-oriented "spectrum of care." Adapting a public health taxonomy, interventions are organized into universal, selective, and indicated levels, targeting the prevention of avoidable disability, distress, and participation barriers. This model aligns autism services with whole-child, neurodiversity-affirming, and developmentally informed care, emphasizing relational health, autonomy, and life-course participation.

Understanding Suicide through Coroners' Narratives: implications for primary care from a mixed‑methods study of 157 Coroners' reports.
Suicide is a major public health concern, and general practice is often a recent point of contact before death. While mental illness is well recognised, the broader social and contextual factors influencing suicide risk remain under-reported in primary care and epidemiological research Aim To describe the demographic, clinical, and psychosocial characteristics of individuals who died by suicide, integrating coronial quantitative data with qualitative narrative accounts to identify implications for primary/ secondary care and public health. Design and setting Explanatory sequential mixed‑methods study of 157 consecutive deaths by suicide recorded by coroners (2018-19) across five English local authorities. Method Demographic, clinical, and social data were extracted from coroners' records and summarised descriptively. Narrative case summaries were coded and analysed thematically to identify contextual, relational, and service factors preceding death. Results Of 157 individuals: 79% were male; 65% lived in the most deprived IMD quintile; 85% had a diagnosed mental health condition; 62% had a long‑term physical illness; 41% had a previous suicide attempt. About half consulted a GP in the preceding three months; mental health featured in about half of those consultations. Common stressors were relationship breakdown (37.2%), housing instability (22.1%), and work pressures (18.2%). Seven interlinked themes were identified: Mental health; Alcohol/Substance use, Physical health; Social connectedness; Life course trauma, Socioeconomic and Structural Vulnerability; Healthcare access. Service transitions were key vulnerability points Conclusion Coroners' records offer important insights into the complex circumstances preceding suicide and highlight opportunities for GPs to recognise intersectional complexity and support integrated, cross-sector suicide prevention approaches.

[Strategy of persistence (facts, hypotheses)].
The universal phenomenon of virus persistence is considered to be a regular phenomenon primarily meeting the interests of the host. Examinations of 1112 patients with various diseases of the nervous system revealed a certain dependence of macroglobulin measles antibody upon the character of the disease and the intensity of demyelinization process. These data do not suggest the etiological role of the persisting measles virus in the genesis of multiple sclerosis and a large group of other nervous system diseases (SSPE). Similar results were obtained in analogous examinations of patients for macroglobulin mumps antibody. The results indicate the role of persisting viruses in the formation of solid specific immunity as well as their importance for nonspecific protection against other immunologically similar diseases. Virus persistence is considered to be a certain antiviral strategy of the body based on accumulation in the life course of a considerable number of persisting viruses on which both specific and nonspecific antiviral protection is founded. Congenital or acquired defects of immunity cause the development of the persisting infection and appearance of some chronic diseases of the nervous system.

Narcolepsy: a family study.
We obtained medical and psychological assessments and 48-hr polysomnographic recordings on five sisters, three of whom had narcolepsy. Of the three, two were identical twins. All three narcoleptic sisters cited emotional stress and environmental demands for sustained performance as the major factors which aggravated their symptoms, and corresponding to this, the illness followed a different life course in each of the three. Most striking were the differences between the twin sisters in clinical symptoms and polysomnographic signs. One sister suffered from all the symptoms of narcolepsy and her sleep recording showed the typical sleep onset REM periods of the disease. Her twin suffered only from excessive daytime drowsiness and her sleep recording was normal--at least by the usual criteria. The sleep of all three narcoleptic sisters, however, was significantly more fragmented than that of their normal siblings. Our data suggested that excessive sleep fragmentation was a basic feature of narcolepsy and that it betrayed a constitutional predisposition for sleep to dissociate into its components and to become distributed around the nycthemeron. This process could be aggravated by emotional stress and by environmental demands for sustained vigilance, and this in turn, created the differences in symptoms and signs between individuals with identical genetic predispositions.

Encopresis in adolescence: two case studies.
Encopresis is an underreported psychopathological symptom of adolescence, not necessarily defining a specific diagnostic entity. The two cases presented offer an opportunity to evaluate encopresis occurring in markedly different adolescent pathological entities and developmental backgrounds. The first patient presented a longitudinal life course wherein toilet training and fecal considerations were prominent throughout his development. Indeed, this young man had such areas of cohesive functioning, as to be appropriately considered within the range of characterological pathology, severe, though it may be. In marked contrast, the second patient's encopresis represented but a small part of a totally encompassing psychotic disintegration.

Serum alpha-fetoprotein in a mouse strain (C3H-Avy fB) with spontaneous hepatocellular carcinomas.
In a study of the association between circulating alpha-fetoprotein concentrations and spontaneous hepatocellular carcinomas, we examined C3H-Avy fB mice, which with age consistently demonstrate a rapidly increasing incidence of hepatic cancer. Although elevated alpha-fetoprotein levels are observed in association with the majority of these tumors, no elevation of alpha-fetoprotein was observed during the life course of non-tumor-bearing mice despite their age-dependent risk for hepatic cancer. Therefore, whatever the evolutionary or age-related biological changes may be that lead to tumor formation in this mouse, they are not linked to the synthesis of significant amounts of this oncofetal protein.

Morphological and histochemical changes of ultimobranchial follicles of the rat thyroid in the course of postnatal life.
Morphological and histochemical changes of ultimobranchial follicles of thyroid have been investigated in rats from newborn to 18 months of age. The first well-delimited ultimobranchial follicles, though with no lumen, were detected in the thyroid gland of 10-day-old rats. At 30 days of age, follicles possessing regular lumina were present in the thyroid. With age, the follicles gradually increased in volume assuming extreme dimensions in adult age. The follicles displayed varying shapes from simple cysts to bizarre forms. From the age of 50 days the cells of the follicular wall are separated from the cell debris contained in the lumen. The latter gave a PAS positive reaction. The cells of the ultimobranchial follicles did not exhibit argyrophilia and metachromasia showing that they differ considerably from the C-cells likewise of ultimobranchial origin, which are known to give marked argyrophilic and metachromatic reactions.
