Minipuberty is a term describing transient postnatal activation of the hypothalamic-pituitary-gonadal axis, likely playing an important role in the postnatal growth of female genital organs and breasts. Unlike infant boys, there are no data concerning the impact of gestational hypothyroidism on the course of minipuberty in infant girls. Therefore, the aim of the current study was to investigate the reproductive axis and genital organs in daughters of women with thyroid hypofunction during pregnancy. The study population included three matched groups of infant girls: offspring of women with thyroid hypofunction non-substituted or inadequately treated during gestation (group 1), descendants of women adequately substituted throughout pregnancy (group 2), and daughters of healthy women (group 3). Salivary concentrations of estradiol, progesterone, 17-hydroxyprogesterone, and androgens (testosterone, androstenedione, and dehydroepiandrosterone sulfate) and urine levels of gonadotropins were measured monthly from month 1 to month 6, once every two months between postnatal months 6 and 12, and once every three months between postnatal months 12 and 18. During each visit, we also determined ovarian volume, uterine length, and breast diameter. Concentrations of FSH, LH, and estradiol were lowest in group 1, and this group was also characterized by the shortest detection period for gonadotropins and estradiol. These differences were paralleled by differences in ovarian volume, uterine length, and breast diameter. There were no differences between groups 2 and 3 in levels of both hormones and in the size of the measured structures. The obtained results seem to indicate that non-substituted or inadequately substituted hypothyroidism during pregnancy may impair the course of minipuberty in the female offspring.

A woman in her 70s with well-controlled HIV on antiretroviral therapy presented with a several-month history of an asymptomatic perianal lesion. Skin examination showed a 0.5-1 cm red-pink, shiny, exophytic papule with visible telangiectasias near the anal verge.

Background: As Generation Z two-spirit, lesbian, gay, bisexual, transgender/trans, queer, intersex, asexual and others who identify as part of sexual and gender diverse communities (2SLGBTQIA +) enter adulthood, contemplation of family creation may be challenged by biological and/or social infertility. Despite some advances in societal acceptance of gender and sexual minorities, family planning and reproductive healthcare remain heteronormative. To explore reproductive decision-making and how future families are conceptualized across genders, we evaluated perceptions of Ontario, Canada non-parenting, 2SLGBTQIA + emerging adults.

An 88-year-old woman presented with a longstanding history of dizziness, tremors, and progressive mental and physical decline, significantly impairing her mobility and autonomy. Recently discharged from an ICU, the patient required extensive support for daily activities. Diagnostic evaluations, including EEG and analysis, revealed irregular frequency peaks and altered cortical activity, particularly in the frontal and prefrontal regions.

Background: Adverse events in childhood are linked to cancer risk across the life course, but evidence is lacking regarding parental death during childhood and breast cancer (BrCa) characteristics. We investigated whether parental loss in childhood defines women at higher risk of BrCa incidence and aggressive disease.
Methods: The Child Health and Development Studies (CHDS) comprises over 15,000 families who enrolled during mothers' pregnancies between 1959-1967; family members were followed for cancer incidence and cause-specific mortality.

Background: Pediatric respiratory syncytial virus (RSV)-related acute lower respiratory tract infection (LRTI) commonly requires hospitalization. The Clinical Progression Scale Pediatrics (CPS-Ped) measures level of respiratory support and degree of hypoxia across a range of disease severity, but it has not been applied in infants hospitalized with severe RSV-LRTI.
Methods: We analyzed data from a prospective surveillance registry of infants hospitalized for RSV-related complications across 39 U.
