Making waves: toward systems-level interpretation of hormonal and endogenous biomarkers in wastewater-based epidemiology.

Wastewater-based epidemiology (WBE) has proven invaluable for population health monitoring, most notably during the COVID-19 pandemic. Yet current WBE largely relies on exogenous markers such as drugs, pathogens, and their metabolites, limiting surveillance to what communities are exposed to. We argue for expanding WBE towards endogenous biomarkers, particularly hormones, which provide insights into physiological stress, metabolic function, and endocrine activity. Hormone-based WBE offers new opportunities to capture population-level biological responses to societal and environmental stressors, disasters, and chronic disease burdens at the community scale. This perspective outlines a systems-level framework for integrating hormonal signals in wastewater with clinical data, behavioral indicators, environmental factors, and digital markers to support more robust and context-aware public health surveillance. We highlight key technical considerations, interpretive challenges, and opportunities for translational pilot studies. By moving beyond exposure tracking toward more integrated interpretation of biological responses, hormone-informed WBE may contribute to more resilient, inclusive, and actionable public health infrastructure.

Understanding septo-optic dysplasia: Endocrine implications and ophthalmic consequences.

Septo-optic dysplasia (SOD) is a heterogeneous neurodevelopmental disorder classically defined by optic nerve hypoplasia, hypothalamo-pituitary dysfunction, and midline brain abnormalities, although the full triad is not consistently present. This review synthesises current evidence on the developmental, endocrine, ophthalmic, and neuroradiological dimensions of the SOD/optic nerve hypoplasia spectrum. Shared embryological origins of the optic pathways, hypothalamus, and pituitary, together with disruption of inductive signalling pathways and pathogenic variants in developmental regulators including SOX2, HESX1, SOX3, and OTX2, provide a mechanistic basis for combined ocular and pituitary phenotypes. Clinically, affected children may present with nystagmus, strabismus, visual impairment, neonatal hypoglycaemia, or evolving pituitary hormone deficiencies, and remain at risk of neurodevelopmental morbidity. Neuroradiological studies have expanded the phenotype beyond classical midline defects to include malformations of cortical development and SOD-plus presentations. Current evidence supports longitudinal endocrine surveillance, detailed ophthalmic assessment, and multidisciplinary care, including timely hormone replacement and developmental support where indicated.

Thyrotoxicosis and pregnancy. An analysis of 43 pregnancies in 42 thyrotoxic mothers.

During the period 1965-1976, 43 pregnancies in 42 thyrotoxic mothers were seen. Thirty-nine pregnancies in 38 patients were analyzed further. Twenty-six patients (27 pregnancies) were treated with antithyroid agents with (9) or without (17) supplemental thyroid hormone therapy and 5 were subjected to subtotal thyroidectomy. In these groups spontaneous abortion occurred in 4 patients (12.5%), prematurity in 3 (9.4%) and perinatal death in one whereas 25 pregnancies ended at term (78%). Two pairs of twins were born and the number of live children in these 32 pregnancies was 29. Hypothyroidism developed in one patient after operation. Thyroid crisis occurred at delivery in one patient in whom the antithyroid therapy was interrupted before labour. Seven patients were not treated with specific antithyroid therapy. In this group there was one twinbirth, one premature birth, one stillbirth and one child died shortly after birth. Thyroid crises developed at delivery in two mothers. The authors use subtotal thyroidectomy if usual indications for operation are present and antithyroid therapy when the thyroid gland is small and diffuse. Beta-receptor blocking agents are recommended only as adjuncts to the antithyroid therapy. A close surveillance of the patients and the free thyroid hormone level during therapy is important and after thyroidectomy treatment with thyroid hormone is recommended until after delivery.

[Lithium and thyroid function. Significance of the TRH test in the diagnosis of lithium-induced thyroid dysfunction].

The treatment by lithium is known to involve certain endocrine complications. Those concerning the thyroid function, with risk of a frank hypothyroidy, are the most important. Aiming to appreciate the frequence and the intensivity of the endocrine effects of lithium, the thyroid parameters and the steady state of the hypothalamo-pituitary-thyroid axis were tested using the TRH test in 52 patients with maniaco-depressive psychosis with special attention to TSH, prolactin and growth hormone: 24 out of them were treated for 1 month to 6 years by lithium; the 28 others were considered as controls. The lithium treatment involves a decrease in the free thyroxine index (1.78 +/- 0.09 vs 2.16 +/- 0.09; p less than 0.01), an increase in the mean baseline TSH level (5.80 +/- 1.49 vs 2.70 +/- 0.24 microU/ml; p less than 0.05) and a noteworthy increase in the TSH responsiveness to TRH (22.7 +/- 2.14 vs 9.75 +/- 1.63 microU/ml; p less than 0.005). The TSH supranormal responses were neither correlated with the length of the treatment nor with the age of the patients. They appear as the consequence of a decrease in the thyroidal hormone secretion. The basal and stimulated prolactinemias remain comparable in the two groups of patients and no response of growth hormone occured after TRH. The TRH test must be considered as a useful complement for the surveillance of the patients treated with lithium because it permits to diagnose early the lithio-induced thyroid dysfunction.

Interactions between age and the neuroendocrine and immune systems.

Three conclusions are suggested by some of the recent work on aging, immunology and the neuroendocrine system. 1) There appears to be sufficient data to implicate the neuroendocrine system in both the maturation and the senescence of at least some components of the immune system. 2) The thymus by its presence or its absence appears to influence certain functions of the pituitary; thus, there appears to be a possible reciprocal relationship between the pituitary and the thymus. 3) Changes in the levels of pituitary hormones or hormones that are controlled by the pituitary can restore in older rats and mice certain functions that are generally considered as part of the immune surveillance and defense system. Consequently, it can be hoped that further studies of neuroendocrine-immune relationships might lead to an understanding of some of the causes for the decline in immune competence with age in mammals.

[Monitoring of side effects in patients treated with corticosteroids of cytotoxic drugs (author's transl)].

Side effects have to be monitored carefully in all patients receiving drugs profoundly affecting their metabolism. Corticosteroids produce the well-known Cushing's syndrome. Children rarely develop gastric ulcers or disturbances of haemostasis. If steroids are administered for more than one year, the eyes have to be examined for signs of cataract. Rarely, the pseudotumor cerebri syndrome (increased intracranial pressure) may be observed. A monitoring schedule adapted from adult medicine for paediatric purposes is proposed in the text. Nowadays, mostly combinations of cytotoxic drugs are used. Often, doses are as high as the patient can tolerate them. Effects of these drugs are especially marked upon rapidly proliferating tissues such as the haematopoietic system and gastrointestinal mucosa. Immunosuppression may have very serious consequences. Infections caused by organisms usually considered as little pathogenic (e.g., pneumocystis carinii) may become deleterious; some infections may remain concealed or produce fever as the only symptom. Particular side effects of certain cytotoxic drugs are described in the text. Many therapeutic regimens are now standardized, as are monitoring schedules. Frequency and nature of the necessary controls depend upon the disease treated and the kind of therapy applied, as well as on its intensity. Both hospital and family doctors are indispensable for this surveillance; they must remain in close contact with each other.

Aspiration curettage for asymptomatic patients receiving estrogen.

Recent epidemiologic data suggest that patients treated with exogenous estrogens have an increased risk of developing endometrial carcinoma and support the concept that patients taking estrogens must be monitored with special vigor. The hypothesis that endometrial aspiration curettage might be an appropriate modality to accomplish adequate surveillance was tested from January 1, 1976, to January 1, 1977, on a group of 208 consecutive patients undergoing hormonal replacement therapy. Although no patient in the test group experienced abnormal or unusual bleeding, focal adenomatous hyperplasia or a more severe lesion was found in 16.0% of the specimens. Among these were 4 cases of endometrial adenocarcinoma and 2 of atypical adenomatous hyperplasia. This study demonstrated that routine endometrial aspiration curettage of patients receiving exogenous hormone replacement therapy can not only help diagnose very early lesions which are amenable to definitive and completely corrective treatment, but also can uncover significant endometrial pathology before it becomes symptomatic. It further suggests the possibility that the incidence of such pathology among this category of patients might be higher than previously suspected.

Pituitary adenomas and dyspituitarism.

Recent studies of the structure and function of pituitary adenomas reveal that the majority are functional and that the commonest type is a prolactin secreting adenoma. Studies of hypothalamic-pituitary function provide evidence to suggest that the adenoma develops following prolonged hypothalamic stimulation of the pituitary gland, and that the clinical dyspituitarism is due to the hypothalamic-pituitary dysfunction and not to pituitary destruction by the adenoma. Pituitary adenomas may be classified into those due to a basic neuroendocrine dysfunction (prolactin secreting, acromegaly, Cushing's disease) and those arising secondary to end-organ failure (TSH and FSH secreting). The former group have APUD characteristics and may form part of a pluriglandular syndrome of apudomas. The persistence of a basic neuroendocrine dysfunction following the surgical removal of an adenoma explains the frequent recurrence of symptoms in patients and indicates a need for continued surveillance and long-term therapy.

Management of toxic megacolon: the significance of early recognition in medical management.

Twenty-seven patients with acute toxic dilatation of the colon (TM) as a complication of inflammatory disease of the colon are reported. To emphasize the importance of early recognition and therapy, we separated the patients into two groups: 19 were receiving care by the authors (series A) before the development of TM, and eight were seen in consultation after its onset (series B), TM subsided with medical therapy in 13 episodes among 19 patients in series A and two of eight B. The others underwent surgical therapy. There were no deaths in either group. The differences in management and mortality from other reports suggest a program of surveillance and therapy for this life-threatening situation.

Time-varying hazard rates reveal patterns of progression in HR+/HER2- metastatic breast cancer: Towards risk-adapted monitoring.

BACKGROUND: optimal imaging intervals for patients with hormone receptor-positive/HER2-negative metastatic breast cancer (MBC) remains undefined. Aim of this study was to analyze the temporal patterns of disease progression to identify high risk subgroups that may benefit from intensified monitoring. METHODS: we analyzed 149 hormone receptor-positive/HER2-negative MBC patients prospectively enrolled in the MAGNETIC.1 trial (NCT05814224) and treated with first line endocrine therapy. Hazard rates (HR) for disease progression were determined according to clinico-pathological and liquid biopsy features. RESULTS: in the overall population, two distinct progression-risk peaks emerged at 2-3 months (32.9/1000 person-months) and at 24 months (28.0/1000). Higher risk of progression was observed in lobular carcinoma (61.1) [HR 61.12 per 1000 person month (pm)], progesterone receptor-negative status (HR 39.07), fulvestrant-based treatment (HR 46.88), liver metastases (HR 59.00), and presence of ≥ 3 metastatic sites (HR 40.10). CONCLUSIONS: Hazard distribution in hormone receptor-positive/HER2-negative MBC is biphasic and modulated by readily available clinical variables. High-risk subgroups may benefit from intensified radiologic and liquid-biopsy surveillance during the first three months and around two years after treatment start.

SUMO: a regulator of gene expression and genome integrity.

Post-translational modification with the ubiquitin-like SUMO protein is involved in the regulation of many cellular key processes. The SUMO system modulates signal transduction pathways, including cytokine, Wnt, growth factor and steroid hormone signalling. SUMO frequently restrains the activity of downstream transcription factors in these pathways presumably by facilitating the recruitment of corepressors or mediating the assembly of repressor complexes. Additionally, evidence is accumulating that SUMO controls pathways important for the surveillance of genome integrity. SUMO regulates the PML/p53 tumour suppressor network, a key determinant in the cellular response to DNA damage. Moreover, proteins that maintain genomic stability by functioning at the interface between DNA replication, recombination and repair processes undergo SUMOylation. We will discuss some key findings that exemplify the role of SUMO in transcriptional regulation and genome surveillance.
