Prenatal stress can lead to the programming of the neuroendocrine system in male offspring, disrupting the hypothalamic testicular axis and adversely affecting the reproductive health of male offspring. This study aimed to determine the long-term effects of prenatal stress on the KISS1 system in male offspring and the effects on reproductive function in male offspring. Sixteen pregnant females were divided into a prenatal control group (PC, n = 8) and a prenatal stress group (PS, n = 8). The PS group was modeled with chronic unpredictable mild stress (CUMS) from day 1 of gestation to full-term delivery. Differences between the two groups in various maternal parameters, including glucocorticoid secretion, litter size, and the effects of male offspring birth weight, the KISS1 system, and reproductive function, were determined. Male offspring of PS dams had lower birth weights compared to prenatal controls.KISS1 gene expression is reduced at birth and in adult PS offspring, and its receptor KISS1-R protein is similarly reduced in PS offspring at birth and adulthood. In adulthood, PS male offspring show significantly reduced sex hormone production, altered testicular morphology, reduced maturation of their supporting cells, and decreased expression of connexin 43 (CX43), leading to an altered sperm microenvironment and reduced sperm quality. In conclusion, prenatal stress leads to adverse changes in the KISS1 system in male offspring and decreased reproductive function.

Because the causes of combined pituitary hormone deficiency (CPHD) are complex, the etiology of congenital CPHD remains unknown in most cases. The aim of the study was to identify the genetic etiology of CPHD in a well-defined single-center cohort. In total, 34 children (12 girls) with congenital CPHD (growth hormone (GH) deficiency and impaired secretion of at least one other pituitary hormone) treated with GH in our center were enrolled in the study. Their median age was 11.2 years, pre-treatment height was −3.2 s.d., and maximal stimulated GH was 1.4 ug/L. Of them, 30 had central adrenal insufficiency, 27 had central hypothyroidism, ten had hypogonadotropic hypogonadism, and three had central diabetes insipidus. Twenty-six children had a midline defect on MRI. Children with clinical suspicion of a specific genetic disorder underwent genetic examination of the gene(s) of interest via Sanger sequencing or array comparative genomic hybridization. Children without a detected causal variant after the first-tier testing or with no suspicion of a specific genetic disorder were subsequently examined using next-generation sequencing growth panel. Variants were evaluated by the American College of Medical Genetics standards. Genetic etiology was confirmed in 7/34 (21%) children. Chromosomal aberrations were found in one child (14q microdeletion involving the OTX2 gene). The remaining 6 children had causative genetic variants in the GLI2, PROP1, POU1F1, TBX3, PMM2, and GNAO1 genes, respectively. We elucidated the cause of CPHD in a fifth of the patients. Moreover, our study supports the PMM2 gene as a candidate gene for CPHD and suggests pathogenic variants in the GNAO1 gene as a potential novel genetic cause of CPHD.

Background
Differences/disorders of sex development (DSD) encompass a wide range of conditions. Their clinical spectrum and etiological diagnosis have not been reported in Moroccan patients.
Aims
The study aims to highlight the clinical spectrum, etiological diagnosis, and management of patients with DSD.
Subjects and methods
This is a retrospective study of all patients diagnosed with DSD under the age of 18 years, who were referred to the Pediatric Endocrinology Department and the Medical Genetics Laboratory at HASSAN II University Hospital of Fez between June 2018 and June 2023.
Results
Out of 57 patients, 54.4% (n = 31) were diagnosed with 46,XX DSD, the most common type, while 45.6% (n = 26) had 46,XY DSD. Patients with 46,XX DSD presented earlier than those with 46,XY DSD, at a median age of 0.08 years and 0.96 years, respectively. The most commonly reported complaint was atypical genitalia. At the first presentation, the sex of rearing was already assigned to 26 males and 27 females. All patients with 46,XX DSD were diagnosed with congenital adrenal hyperplasia (CAH) at a median age of diagnosis of 0.92 years. Of these, 11 patients were raised as males. Disorders of androgen action or synthesis were more common in XY patients (69.2%). The consanguinity rate was 46.5%, and there were 19 cases with a positive family history, with 10 siblings having died.
Conclusion
DSD are not rare in Morocco. Overall, CAH remains the most frequent DSD etiology. Molecular genetic analyses are needed to determine the accurate etiological distribution of DSD, especially in XY patients.

Objective: Hyperthyroidism, a prevalent endocrine disorder, can lead to complications such as liver failure due to the liver's essential role in thyroid hormone metabolism. The study aimed to elucidate the respective contributions of 131I or/and ALSS in managing hyperthyroidism alongside liver failure.
Methods: A retrospective analysis was carried out on 74 patients diagnosed with severe liver failure in the context of Graves' disease. Patients were categorized into three groups: Group A (n=34) received 131I treatment, group B (n=17) underwent 131I and ALSS treatment, and group C (n=24) received ALSS treatment alone.
Results: Throughout the treatment period, the liver function indexes in all groups exhibited a decline trend. The thyroid function of group A and group B treated with 131I was significantly improved compared with that before treatment. There was no significant change in thyroid function in group C. After the correction of hyperthyroidism, significant improvements were observed in the liver function of individuals in group A and B, particularly with more noticeable amelioration compared to group C. After two months of treatment, the efficacy rates for the three groups were 79.41%, 82.35%, and 60.87% respectively. Mortality rates of the three groups were 5.88%,17.65% and 36% (p<0.01). Group B, receiving both 131I and ALSS treatments, exhibited a lower mortality rate than group C.
Conclusion: In cases of severe liver failure accompanied by hyperthyroidism, prompt administration of 131I is recommended to alleviate the adverse effects of hyperthyroidism on liver function and facilitate a conducive environment for the recovery of liver functionality.

Background: There is a paucity of information on health-related quality of life (HRQoL) outcomes in parents and children with conditions affecting sex development. The objective of this study was to develop short forms of HRQoL questionnaires which consist of a 63-item and 25-item parent self-report (PSR) and parent proxy-report (PPR), respectively, optimising use in routine clinic settings.
Methods: Short questionnaires were developed following exploratory factor analysis using raw data from 132 parents. Long and short PSRs were completed by 24 parents of children with conditions affecting sex development with median age of 3.6 years (range 0.1, 6.6); 21 (88%) were boys and 11 (46%) had proximal hypospadias. A subset of 19 parents completed long and short PPRs.
Results: Item selection based on factor loadings of >0.8 and expert consultation, produced short PSR and PPRs containing 16 and 7 items, respectively. There was no statistically significant difference in 11 out of 12 (92%) scales on the PSR and 4 out of 5 (80%) scales on the PPR when comparing short and long questionnaire scores. Short and long questionnaires took <1 minute and 5 minutes for completion, respectively. Eighteen parents (75%) reported that the time taken to complete short questionnaires was acceptable; 10 (42%) preferred short questionnaires. Ten (42%) versus 6 (25%) stated a preference for completing short versus long questionnaires.
Conclusion: Short versions were largely representative of the long questionnaires and are acceptable to evaluate psychosocial distress in young children and their caregivers. Further psychometric validation of short forms is warranted.

The global burden of controlling and managing diabetes mellitus (DM) is a significant challenge. Despite the advancements in conventional DM therapy, there remain hurdles to overcome, such as enhancing medication adherence and improving patient prognosis. Digital therapeutics (DTx), an innovative digital application, has been proposed to augment the traditional disease management workflow, particularly in managing chronic diseases like DM. Several studies have explored DTx, yielding promising results. However, certain concerns about this innovation persist. In this review, we aim to encapsulate the potential of DTx and its applications in DM management, thereby providing a comprehensive overview of this technique for public health policymakers.

Objective: Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHAD) is rare, and manifestations of autonomic dysregulation are diverse and may be overlooked. We aimed to evaluate the incidence of these manifestations.
Methods: Patients with ROHHAD syndrome reported before and after 2019 were divided into Groups 1 and 2. Patients who were diagnosed at three regional hospitals in China were included in Group 3. We collected the age of each specific term of the ROHHAD (neurogenic tumor, NET) acronym and the detailed manifestations of each term, and compared them among the three groups.
Results: A total of 16 patients were diagnosed within the 2-year period. Two had neurogenic tumors and cognitive and behavioral abnormalities before developing rapid obesity. At least 93.8% of the patients had ≥ 4 symptoms of autonomic dysregulation. When comparing autonomic dysregulation among Groups 1–3, the rates of cardiovascular manifestations were NA vs. 12.8% vs. 81.2%; gastrointestinal disturbances were 11.4% vs. 8.5% vs. 62.5%; strabismus was 25.7% vs. 12.8% vs. 62.5%; sleep disturbance was NA vs. 6.4% vs. 50.0%; and abnormal pain threshold was NA vs. 10.6% vs. 25.0% (all p<0.05). The rates of cognitive and behavioral abnormalities were NA vs 29.8% and 87.5% (p<0.01).
Conclusions: Rapid-onset obesity is not always the first sign of ROHHAD syndrome. Higher rates of autonomic dysregulation and cognitive and behavioral abnormalities with multiple manifestations of autonomic dysregulation coexisted in our cohort, indicating that evaluations of autonomic function and the limbic system should be strengthened when assessing this condition.

Objective
Cushing’s syndrome (CS) is associated with an 18-fold greater risk of venous thromboembolism (VTE). We aimed to identify factors which provoke VTE among patients with CS and VTE and to describe the anticoagulant regimen used in these cases.
Methods
In this retrospective observational study, patients included in the European Registry on CS (ERCUSYN) in Krakow center, Poland, were followed for the occurrence of VTE and anticoagulant treatment. We identified factors provoking VTE according to the International Society of Thrombosis and Hemostasis (ISTH), along with factors included in the Padua score and CS-VTE score.
Results
Of the 128 patients followed for a median of 4.3 years, there were nine patients who experienced ten VTE episodes (prevalence of 7.8% and incidence of 13.4 per 1000 patient-years). All VTEs were classified as provoked according to the ISTH guidance, predominantly due to the transient major and minor (50% and 20%, respectively) factors, while they were less commonly due to persistent (30%) factors. In 2/9 patients, we could not identify any risk factor for VTE according to the Padua score, while in 2/6 patients according to the CS-VTE score. Patients were mostly anticoagulated with vitamin K antagonists (4/8 patients), followed by direct oral anticoagulants (3/8) and low-molecular-weight heparin (1/8). The median duration of anticoagulation was 2.75 years and exceeded beyond the primary treatment in 28% of episodes provoked by transient factors.
Conclusion
Further, multicenter studies are required to create a validated thrombotic risk score and guidelines regarding VTE treatment in CS patients.

Purpose
This review aims to discuss the psychological aspects of Graves’ ophthalmopathy (GO), estimate the prevalence of depression and anxiety disorders in GO, examine whether these psychiatric disorders are more prevalent in GO than in Graves’ disease (GD) without eye disease, and evaluate the main contributors for depression and anxiety in GO.
Methods
A review of the literature.
Results
Both depression and anxiety are associated with GO. The prevalence of depression and anxiety disorders specifically in GO patients was estimated at 18–33% and 26–41%, respectively. The reported prevalence in GD patients ranged from 9% to 70% for depression and from 18% to 88% for anxiety disorders. Significantly higher levels of depression and anxiety were found in GD patients compared with patients with non-autoimmune hyperthyroidism. Conflicting results have been reported regarding the association of antithyroid autoantibodies with depression and anxiety disorders. Serum thyroid hormone levels do not correlate with the severity of depression and anxiety. An improvement of psychiatric symptoms is observed in hyperthyroid patients after treatment of thyrotoxicosis. Moreover, depression and anxiety are significantly related to impaired quality of life (QoL) in GO. Exophthalmos and diplopia were not associated with depression nor anxiety, but orbital decompression and strabismus surgery do seem to improve QoL in GO patients.
Conclusions
The results of this review suggest that altered thyroid hormone levels and autoimmunity are prognostic factors for depression and anxiety in GO. With regard to the visual and disfiguring aspects of GO as contributing factors for depression and anxiety, no decisive conclusions can be made.
