Associations Between Age at Menopause, Vascular Risk, and 3-Year Cognitive Change in the Canadian Longitudinal Study on Aging.

Mounting evidence supports sex differences in Alzheimer disease (AD) risk. Vascular and hormonal factors may together contribute to AD risk in female adults. We investigated whether age at menopause, vascular risk, and history of hormone therapy (HT) containing estrogens together influence cognition over a 3-year follow-up period. We hypothesized that earlier menopause and elevated vascular risk would have a synergistic association with lower cognitive scores at follow-up and that HT containing estrogens would attenuate this synergistic association to preserve cognition. We used data from postmenopausal female participants and age-matched male participants in the Canadian Longitudinal Study on Aging. Vascular risk was calculated using a summary score of elevated blood pressure, antihypertensive medications, elevated low-density lipoprotein cholesterol, diabetes, smoking, and obesity. Cognition was measured with a global cognitive composite at baseline and 3-year follow-up. Linear models tested independent and interactive associations of age at menopause, vascular risk, and HT history with cognition at 3-year follow-up, adjusting for baseline cognition, baseline age, years of education, and test language (English/French). We included 8,360 postmenopausal female participants (mean age at baseline = 65.0 ± 8.53 years, mean age at menopause = 50.1 ± 4.62 years) and 8,360 age-matched male participants for comparison. There was an interaction between age at menopause and vascular risk, such that earlier menopause and higher vascular risk were synergistically associated with lower cognitive scores at follow-up (β = 0.013, 95% CI 0.001-0.025, p = 0.03). In stratified analyses, vascular risk was associated with lower cognitive scores in female participants with earlier menopause (menopausal ages 35-48 years; β = -0.044, 95% CI -0.066 to -0.022, p < 0.001), but not average (ages 49-52 years; β = -0.007, 95% CI -0.027 to 0.012, p = 0.46) or later menopause (ages 53-65 years; β = 0.003, 95% CI -0.020 to 0.025, p = 0.82). The negative association of vascular risk with cognition in female participants with earlier menopause was stronger than the equivalent association in age-matched male participants. HT history did not further modify the synergistic association of age at menopause and vascular risk with follow-up cognition (β = -0.005, 95% CI -0.032 to 0.021, p = 0.69). Endocrine and vascular processes may synergistically contribute to increased risk of cognitive decline in female adults. These findings have implications for the development of sex-specific dementia prevention strategies.

A Prospective Randomized Trial of Neoadjuvant Chemohormonal Therapy vs Hormonal Therapy in Locally Advanced Prostate Cancer Treated by Radical Prostatectomy.

Benefits of docetaxel-based neoadjuvant chemohormonal therapy (NCHT) before radical prostatectomy (RP) remain largely unknown. We explored whether docetaxel-based NCHT would bring pathological benefits and improve biochemical progression-free survival (bPFS) over neoadjuvant hormonal therapy (NHT) in locally advanced prostate cancer. A randomized trial was designed recruiting 141 locally advanced, high-risk prostate cancer patients who were randomly assigned at the ratio of 2:1 to the NCHT group (75 mg/m2 body surface area every 3 weeks plus androgen deprivation therapy for 6 cycles) and the NHT group (androgen deprivation therapy for 24 weeks). The primary end point was 3-year bPFS. Secondary end points were pathological response including pathological downstaging and minimal residual disease rates. The NCHT group showed significant benefits in 3-year bPFS compared to the NHT group (29% vs 9.5%, P = .002). At a median follow-up of 53 months, the NCHT group achieved a significantly longer median bPFS time than the NHT group (17 months vs 14 months). No significant differences were found between the 2 groups in pathological downstaging and minimal residual disease rates. NCHT plus RP achieved significant bPFS benefits when compared with NHT plus RP in high-risk, locally advanced prostate cancer. A larger cohort with longer follow-up duration is essential in further investigation.

A fNIRS investigation of menopausal-related symptoms and brain cortical activity in menopause.

This study aimed to delineate the association between menopausal-related symptoms and brain cortical hemodynamics in peri-postmenopause women. Cross-sectional data from a total of 358 Han-Chinese women who visited the Menopause Clinic in the Shanghai Sixth People's Hospital from August 2019 to August 2022. Menopausal-related symptoms were analyzed through Kupperman index (KMI) scale and PSQI scale, while cerebral blood flow was measured using a functional near-infrared spectroscopy (fNIRS). Multiple linear regression model was used to assess the risk factors for subregions of brain hemodynamic response. After adjusting for confounding factors, we identified that menopausal symptom (B=-1.575, 95% CI (-2.661, -0.488), p=0.005) and duration of menopause (B=-14.583, 95% CI (-26.753, -4.192), p=0.007) were independently associated with the lower brain hemodynamic response in the prefrontal lobe, while in the temporal lobe, overweight (BMI≥24kg/m2) was negatively associated with the lower brain cortical activity (B=-36.882, 95% CI (-72.708, -1.056), p=0.044) after adjusting for other confounding variables. Our findings proposed that menopausal symptom and overweight should be attached great importance to the postmenopausal women, which provides clinical evidence for the feasible early detection and effective prevention such as menopausal hormone therapy (MHT) of brain health in postmenopausal women.

Thoracic Endometriosis Detected During Medical Thoracoscopy in a Tertiary Care Setting - A Retrospective Observational Study

Background: Thoracic endometriosis is a very rare clinical situation mostly presenting with pleural diseases, that is often misdiagnosed or missed due to the lack of specific clinical features. This report aims to explore the clinical characteristics, thoracoscopic findings, histopathology, treatment, and prognosis of women with thoracic endometriosis, providing a reference for the diagnosis and management of thoracic endometriosis. Design/Methods: Clinical data of 3 patients diagnosed with pleural endometriosis from among 50 consecutive thoracoscopic procedures conducted in a tertiary care hospital in North Kerala were analysed from electronic hospital records. The clinical features, thoracoscopic findings, histopathological features, treatment process, and prognosis were summarized. Results: Among the 3 female patients with pleural endometriosis, there were 2 cases of catamenial pneumothorax and one case of catamenial haemothorax. The age ranged from 43 years to 44 years. All the 3 cases were diagnosed by thoracoscopic pleural biopsy. Conclusions: Thoracic endometriosis syndrome is extremely rare, and clinical diagnosis is always missed or delayed due to nonspecific symptoms. Diagnosis mainly relies on pathological findings and immunohistochemical detection. Most cases were managed conservatively with hormonal therapy or by inducing surgical menopause.

Abstract P24: Elucidating the Mechanism of Action of Lenvatinib in Estrogen Receptor-Positive (ER+) Breast Cancer

Abstract Background: ER+ breast cancer is the most common subtype of breast cancer. Although most patients respond initially to endocrine therapy (ET), endocrine resistance inevitably develops, leading to disease progression. Lenvatinib, a multi-kinase inhibitor, demonstrated clinical benefit in the treatment of patients with advanced ER+ breast cancer who have progressed on ET in a phase Ib/II clinical trial from our group. Our study aims to elucidate the molecular mechanism of action of lenvatinib in ER+ breast cancer. Methods: A cell viability assay was performed to assess the sensitivity of four ER+ cell lines to lenvatinib. Western blot was used to elucidate its effect on downstream pathway signalling, and cell cycle arrest investigated through flow cytometry. A series of functional assays, including BrdU, colony formation and wound-healing assays assessed proliferative, clonogenic and migratory activity respectively. The effect of lenvatinib on epithelial-mesenchymal transition (EMT) was analysed using RT-qPCR, and compared with siRNA knockdown (KD) of Fgfr1 and Fgfr2. Results: ER+ cell lines demonstrated sensitivity to lenvatinib in the micromolar range. Western blot showed downregulation of FGFR1, FGFR2, pERK and pAKT expression post-treatment. Lenvatinib was found to induce a G1 phase arrest, suppressed cell proliferation in a dose-dependent manner, and diminished both the clonogenic ability and migratory activity of ER+ cells. Lenvatinib treatment reduced expression of Fgfr1, Fgfr2 and the mesenchymal markers N-cad and Fibronectin, while increasing the expression of the epithelial markers E-cad and Claudin-1, indicating potential inhibition of EMT. A similar change in EMT marker expression was observed in Fgfr1 KD but not Fgfr2 KD cells. Conclusion: Lenvatinib demonstrated potent anti-cancer activity and induction of G1 phase arrest, leading to decreased cell proliferation, reduction of clonogenic ability and cell migration. EMT inhibition was also observed, possibly through the FGFR1 signalling pathway. Citation Format: Natasha Gandasasmita, Gauri Vaidya, Arpita Datta, Charlie Marvalim, Joline Si Jing Lim, Soo Chin Lee.

Evaluating first-line therapeutic strategies for metastatic castration-resistant prostate cancer: a comprehensive network meta-analysis and systematic review

ObjectiveThis study aimed to evaluate the relative efficacy and safety of first-line treatment options for metastatic castration-resistant prostate cancer (mCRPC).MethodsWe systematically searched electronic databases, including PubMed and Web of Science, for studies published from their inception to April 3rd, 2023. Inclusion criteria were: 1) Completed Phase III or IV randomized controlled trials (RCTs) registered on ClinicalTrials.gov; 2) Patients with a confirmed diagnosis of mCRPC who had not previously received chemotherapy or novel endocrine therapies. We conducted a network meta-analysis using R software (version 3.4.0). Network graphs and risk of bias graphs were generated using Stata 14.0 and RevMan 5.4, respectively. The primary outcome was overall survival (OS), and the secondary outcome was the incidence of severe adverse events (SAEs).ResultsSeven RCTs encompassing 6,641 patients were included. The network meta-analysis revealed that both docetaxel+prednisone (DP) and cabazitaxel+prednisone (CP) significantly improved OS compared to abiraterone. Compared to placebo, DP showed comparable results to both cabazitaxel 20 mg/m^2+prednisone (C20P) and cabazitaxel 25 mg/m^2+prednisone (C25P) in terms of OS. For SAEs, both DP and C20P were superior to C25P, with no statistical difference between C20P and DP. The probability ranking plots indicated that C25P ranked highest for OS, while DP ranked highest for SAEs.ConclusionsBased on our network meta-analysis, we recommend cabazitaxel 20 mg/m^2+prednisone (C20P) as the primary choice for first-line management of mCRPC, followed by DP. Enzalutamide and abiraterone are suggested as subsequent options. Radium-223 may be considered for patients presenting with bone metastases.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42023443943.

Clinical Manifestation, Risk Factors, and Immune Checkpoint Inhibitor Rechallenge of Checkpoint Inhibitor-Associated Pneumonitis in Patients With Lung Cancer.

Immune-related adverse effects can lead to damage to various systems of the body, checkpoint inhibitor-associated pneumonitis (CIP) is one of the potentially lethal immune-related adverse effects. However, evidence regarding the risk factors associated with CIP is limited. To timely and accurate identification and prompt treatment of CIP, understanding the risk factors for multimorbidity among diverse study populations becomes crucial. We retrospectively analyzed the clinical data of 1131 patients with lung cancer receiving immunotherapy to identify 110 patients with CIP, the clinical characteristics and radiographic features of patients with CIP were analyzed. A case-control study was subsequently performed to identify the risk factors of CIP. The median treatment cycle was 5 cycles and the median time to onset of CIP was 4.2 months. CIP was mainly grade I or II. Most cases improved after discontinuation of immune checkpoint inhibitors (ICIs) or hormone therapy. Severe CIP tended to occur earlier in comparison to mild to moderate cases. The recurrence rate was 20.6% in ICI-rechallenged patients, and patients with relapsed CIP were usually accompanied by higher-grade adverse events than at first onset. Among the 7 patients with relapse, ICI-associated deaths occurred in 2 patients (28.6%). For rechallenging with ICIs after recovery from CIP, caution should be practiced. Male [odds ratio (OR): 2.067; 95% CI: 1.194-3.579; P= 0.009], history of chest radiation (OR: 1.642; 95% CI: 1.002-2.689; P= 0.049) and underlying lung disease (OR: 2.347; 95% CI: 1.008-5.464; P=0.048) was associated with a higher risk of CIP.

Risks of Oral and Maxillofacial Surgery in Patients with Thyroid Dysfunction: Proper Management Strategies

Oral and maxillofacial surgery encompasses procedures for correcting mouth, jaw, and facial issues, posing challenges in patients with thyroid dysfunction due to its impact on the coagulation system. Many authors noted a rise in thyroid disease among younger adults, affecting surgeries traditionally performed in this demographic. Thyroid dysfunction alters hemostasis, with hyperthyroidism increasing thromboembolic risks and hypothyroidism impairing wound healing and causing bleeding tendencies. In OMF surgery, hyperthyroid patients face thromboembolic risks, requiring preoperative assessment, thyroid normalization, and anticoagulant prophylaxis. Hypothyroid patients need optimized hormone therapy, careful hemostasis, and postoperative monitoring. Multidisciplinary collaboration among endocrinologists, surgeons, and hematologists is crucial for tailored management strategies. In conclusion, understanding thyroid dysfunction's hemostatic impact is vital for safe OMF surgery, necessitating personalized perioperative care strategies.

The cost-effectiveness of osteoporosis medications for preventing periprosthetic fractures following femoral neck fracture indicated hip arthroplasty: a break-even analysis.

Osteoporosis treatment following arthroplasty for femoral neck fracture (FNF) is associated with lower rates of periprosthetic fracture (PPF). Although cost-effective in reducing the rate of secondary fragility fracture, the economic viability of osteoporosis treatment in preventing PPF has not been evaluated. Therefore, the purpose of this study is to use a break-even analysis to determine whether and which current osteoporosis medications are cost-effective in preventing PPF following arthroplasty for FNFs. Three-year average cost of osteoporosis medication (oral bisphosphonates, estrogen hormonal therapy, intravenous (IV) bisphosphonates, denosumab, teriparatide, and abaloparatide), costs of PPF care, and PPF rates in patients who underwent hip arthroplasty for FNFs without osteoporosis treatment were used to perform a break-even analysis. The absolute risk reduction (ARR) related to osteoporosis treatment and sensitivity analyses were used to evaluate the cost-effectiveness of this intervention and break-even PPF rates. Oral bisphosphonate therapy following arthroplasty for hip fractures would be economically justified if it prevents one out of 56 PPFs (ARR, 1.8%). Given the current cost and incidence of PPF, overall treatment can only be economically viable for PPF prophylaxis if the 3-year costs of these agents are less than $1500. The utilization of lower cost osteoporosis medications such as oral bisphosphonates and estrogen hormonal therapy as PPF prophylaxis in this patient population would be economically viable if they reduce the PPF rate by 1.8% and 1.5%, respectively. For IV bisphosphonates and newer agents to be economically viable as PPF prophylaxis in the USA, their costs need to be significantly reduced.

Chronotype changes after sex hormone use: A prospective cohort study in transgender users of gender-affirming hormones

ABSTRACT Chronotype, an individual’s preferred sleep-wake timing, is influenced by sex and age. Men sometimes report a later chronotype than women and older age is associated with earlier chronotype. The sex-related changes in chronotype coincide with puberty and menopause. However, the effects of sex hormones on human chronotype remain unclear. To examine the impact of 3 months of gender-affirming hormone therapy (GAHT) on chronotype in transgender persons, this study used data from 93 participants from the prospective RESTED cohort, including 49 transmasculine (TM) participants starting testosterone and 44 transfeminine (TF) participants starting estrogens and antiandrogens. Midpoint of sleep and sleep duration were measured using the ultra-short Munich ChronoType Questionnaire (µMCTQ). After 3 months of GAHT, TM participants’ midpoint of sleep increased by 24 minutes (95% CI: 3 to 45), whereas TF participants’ midpoint of sleep decreased by 21 minutes (95% CI: −38 to −4). Total sleep duration did not change significantly in either group. This study provides the first prospective assessment of sex hormone use and chronotype in transgender persons, showing that GAHT can change chronotype in line with cisgender sex differences. These findings provide a basis for future studies on biological mechanisms and clinical consequences of chronotype changes.

Gonadal hormone deprivation regulates response to tibolone in neurodegenerative pathways

Gonadal hormone deprivation (GHD) and decline such as menopause and bilateral oophorectomy are associated with an increased risk of neurodegeneration. Yet, hormone therapies (HTs) show varying efficacy, influenced by factors such as sex, drug type, and timing of treatment relative to hormone decline. We hypothesize that the molecular environment of the brain undergoes a transition following GHD, impacting the effectiveness of HTs. Using a GHD model in mice treated with Tibolone, we conducted proteomic analysis and identified a reprogrammed response to Tibolone, a compound that stimulates estrogenic, progestogenic, and androgenic pathways. Through a comprehensive network pharmacological workflow, we identified a reprogrammed response to Tibolone, particularly within "Pathways of Neurodegeneration", as well as interconnected pathways including "cellular respiration", "carbon metabolism", and "cellular homeostasis". Analysis revealed 23 proteins whose Tibolone response depended on GHD and/or sex, implicating critical processes like oxidative phosphorylation and calcium signalling. Our findings suggest the therapeutic efficacy of HTs may depend on these variables, suggesting a need for greater precision medicine considerations whilst highlighting the need to uncover underlying mechanisms.

Review of Breast Imaging in Transgender and Gender-Diverse Patients: Gender-Affirming Care, Histopathologic Findings, Breast Cancer Risk, and Screening Recommendations.

Gender diversity, especially pertaining to transgender and gender-diverse (TGD) populations, is often stigmatized. A small but not insignificant number of adults in the United States identify as TGD, including transgender, nonbinary, and other gender identities than cisgender. Accessing health care remains a significant challenge for TGD individuals because many health care systems adhere to a gender binary model and many TGD individuals experience negative interactions when interfacing with health care. There is also a scarcity of literature addressing their unique health care needs, limiting our current understanding of breast cancer risks and screening recommendations for TGD patients. This article reviews important considerations when providing care to TGD patients. It covers background information on gender identity and sexuality, explores gender-affirming care, discusses histopathologic findings of breast biopsy specimens, examines breast cancer risks, and presents current breast cancer screening recommendations for TGD patients. Education on TGD breast cancer risks and screening and creating a standardized screening protocol for TGD patients who may receive gender-affirming care through hormonal and surgical therapies could help improve their health care equity and access.

Racial/ethnic differences in 21-gene recurrence score and survival among patients with estrogen receptor-positive breast cancer

BackgroundDespite numerous studies on racial/ethnic disparities among patients with breast cancer, there is a paucity of literature evaluating racial/ethnic differences in 21-gene recurrence score (RS) and survival differences stratified by RS risk categories. We thus performed an observational cohort study to examine racial/ethnic disparities in the context of RS.MethodsThe National Cancer Database (NCDB) was queried for female patients diagnosed between 2006 and 2018 with estrogen receptor (ER)-positive, pT1-3N0-1aM0 breast cancer who received surgery followed by adjuvant endocrine therapy and had RS data available. Logistic multivariable analysis (MVA) was built to evaluate variables associated with RS ≥ 26. Cox MVA was used to evaluate OS. Subgroup analyses were performed to compare the magnitude of racial/ethnic differences stratified by RS. P values less than 0.017 were considered statistically significant based on Bonferroni correction.ResultsA total of 140,133 women were included for analysis. Of these, 115,651 (82.5%), 8,213 (5.9%), 10,814 (7.7%), and 5,455 (3.9%) were NHW, Hispanic, Black, and API women, respectively. Median (IQR) follow up was 66.2 months (48.0–89.8). Logistic MVA showed that, compared with NHW women, Black women were associated with higher RS (≥ 26 vs < 26: adjusted odds ratio [aOR] 1.19, 95% confidence interval [CI] 1.12–1.26, p < 0.001), while HW (aOR 0.93, 95% CI 0.86–1.00, p = 0.04) and API women (aOR 1.03, 95% CI 0.95–1.13, p = 0.45) were not. Cox MVA showed that, compared with NHW women, Black women had worse OS (adjusted hazards ratio [aHR] 1.10, 95% CI 1.02–1.19, p = 0.012), while HW (aHR 0.85, 95% CI 0.77–0.94, p = 0.001) and API (aHR 0.66, 95% CI 0.56–0.77, p < 0.001) women had better OS. In subgroup analysis, similar findings were noted among those with RS < 26, while only API women were associated with improved OS among others with RS ≥ 26.ConclusionTo our knowledge, this is the largest study using nationwide oncology database to suggest that Black women were associated with higher RS, while HW and API women were not. It also suggested that Black women were associated with worse OS among those with RS < 26, while API women were associated with improved OS regardless of RS when compared to NHW women.

Impact of Distinct Anti-Androgen Exposures on the Plasma Metabolome in Feminizing Gender-Affirming Hormone Therapy.

The plasma metabolome is a functional readout of metabolic activity and is associated with phenotypes exhibiting sexual dimorphism, such as cardiovascular disease. Sex hormones are thought to play a key role in driving sexual dimorphism. Gender-affirming hormone therapy (GAHT) is a cornerstone of transgender care, but longitudinal changes in the plasma metabolome with feminizing GAHT have not been described. Blood samples were collected at baseline and after three and six months of GAHT from transgender women (n = 53). Participants were randomized to different anti-androgens, cyproterone acetate or spironolactone. NMR-based metabolomics was used to measure 249 metabolic biomarkers in plasma. Additionally, we used metabolic biomarker data from an unrelated cohort of children and their parents (n = 3,748) to identify sex- and age-related metabolite patterns. We identified 43 metabolic biomarkers altered after six months in both anti-androgen groups, most belonging to the very low- or low-density lipoprotein subclasses, with all but one showing a decrease. We observed a cyproterone acetate-specific decrease in glutamine, glycine, and alanine levels. Notably, of the metabolic biomarkers exhibiting the most abundant 'sex- and age-related' pattern (higher in assigned female children and lower in assigned female adults, relative to assigned males), 80% were significantly lowered after GAHT, reflecting a shift toward the adult female profile. Our results suggest an anti-atherogenic signature in the plasma metabolome after the first six months of feminizing GAHT, with cyproterone acetate also reducing specific plasma amino acids. This study provides novel insight into the metabolic changes occurring across feminizing GAHT.

CAR-based immunotherapy for breast cancer: peculiarities, ongoing investigations, and future strategies

Surgery, chemotherapy, and endocrine therapy have improved the overall survival and postoperative recurrence rates of Luminal A, Luminal B, and HER2-positive breast cancers but treatment modalities for triple-negative breast cancer (TNBC) with poor prognosis remain limited. The effective application of the rapidly developing chimeric antigen receptor (CAR)-T cell therapy in hematological tumors provides new ideas for the treatment of breast cancer. Choosing suitable and specific targets is crucial for applying CAR-T therapy for breast cancer treatment. In this paper, we summarize CAR-T therapy’s effective targets and potential targets in different subtypes based on the existing research progress, especially for TNBC. CAR-based immunotherapy has resulted in advancements in the treatment of breast cancer. CAR-macrophages, CAR-NK cells, and CAR-mesenchymal stem cells (MSCs) may be more effective and safer for treating solid tumors, such as breast cancer. However, the tumor microenvironment (TME) of breast tumors and the side effects of CAR-T therapy pose challenges to CAR-based immunotherapy. CAR-T cells and CAR-NK cells-derived exosomes are advantageous in tumor therapy. Exosomes carrying CAR for breast cancer immunotherapy are of immense research value and may provide a treatment modality with good treatment effects. In this review, we provide an overview of the development and challenges of CAR-based immunotherapy in treating different subtypes of breast cancer and discuss the progress of CAR-expressing exosomes for breast cancer treatment. We elaborate on the development of CAR-T cells in TNBC therapy and the prospects of using CAR-macrophages, CAR-NK cells, and CAR-MSCs for treating breast cancer.

IgM kappa proliferative glomerulonephritis with monoclonal immunoglobulin deposition complicated with nocardiosis dermatitis: a case report and review of literature

RationaleMonoclonal gammopathy of renal significance (MGRS) represents a group of disorders caused by monoclonal immunoglobulin (M protein) secreted by B cells or plasma cells. Proliferative glomerulonephritis with monoclonal immunoglobulin deposition (PGNMID) is a glomerular disease and a form of MGRS. Here, we presented a rare case of a patient with IgM kappa PGNMID complicated with nocardiosis dermatitis.Patient concerns and diagnosesA 56-year-old man was admitted to the hospital because of cutaneous purpura and proteinuria. His initial pathological diagnosis indicated membranous proliferative glomerulonephritis, IgM(++), and subacute interstitial nephritis. Based on further examination, he was finally diagnosed to have IgM kappa PGNMID and subacute interstitial nephritis. After the initial diagnosis, the patient received hormonal therapy. During the treatment, nocardiosis dermatitis emerged as a complication, and the hormonal therapy was gradually reduced. The patient refused further treatment with rituximab, and his health is currently stable.OutcomesIgM kappa PGNMID complicated with nocardiosis dermatitis is an extremely rare occurrence. Laboratory examination and pathological analysis are required to confirm the diagnosis of this disorder. Timely and accurate diagnosis is essential for the appropriate treatment of PGNMID.

Growth hormone in pediatric chronic kidney disease: more than just height.

Recombinant human growth hormone therapy, which was introduced in the 1980s, is now routine for children with advanced chronic kidney disease (CKD) who are exhibiting growth impairment. Growth hormone usage remains variable across different centers, with some showing low uptake. Much of the focus on growth hormone supplementation has been on increasing height because of social and psychological effects of short stature. There are, however, numerous other changes that occur in CKD that have not received as much attention but are biologically important for pediatric growth and development. This article reviews the current knowledge about the multisystem effects of growth hormone therapy in pediatric patients with CKD and highlights areas where additional clinical research is needed. We also included clinical data on children and adults who had received growth hormone for other indications apart from CKD. Ultimately, having robust clinical studies which examine these effects will allow children and their families to make more informed decisions about this therapy.

Horizons in Endometriosis: Proceedings of the Montreux Reproductive Summit, 14-15 July 2023.

Endometriosis is a complex and chronic gynaecological disorder that affects millions of women worldwide, leading to significant morbidity and impacting reproductive health. This condition affects up to 10% of women of reproductive age and is characterised by the presence of endometrial-like tissue outside the uterus, potentially leading to symptoms such as chronic pelvic pain, dysmenorrhoea, dyspareunia, and infertility. The Montreux summit brought a number of experts in this field together to provide a platform for discussion and exchange of ideas. These proceedings summarise the six main topics that were discussed at this summit to shed light on future directions of endometriosis classification, diagnosis, and therapeutical management. The first question addressed the possibility of preventing endometriosis in the future by identifying risk factors, genetic predispositions, and further understanding of the pathophysiology of the condition to develop targeted interventions. The clinical presentation of endometriosis is varied, and the correlation between symptoms severity and disease extent is unclear. While there is currently no universally accepted optimal classification system for endometriosis, several attempts striving towards its optimisation - each with its own advantages and limitations - were discussed. The ideal classification should be able to reconcile disease status based on the various diagnostic tools, and prognosis to guide proper patient tailored management. Regarding diagnosis, we focused on future tools and critically discussed emerging approaches aimed at reducing diagnostic delay. Preserving fertility in endometriosis patients was another debatable aspect of management that was reviewed. Moreover, besides current treatment modalities, potential novel medical therapies that can target underlying mechanisms, provide effective symptom relief, and minimise side effects in endometriotic patients were considered, including hormonal therapies, immunomodulation, and regenerative medicine. Finally, the question of hormonal substitution therapy after radical treatment for endometriosis was debated, weighing the benefits of hormone replacement.

Nipple-Sparing Mastectomy and Adequate Margins for Patients With Ductal Carcinoma In Situ.

For patients with ductal carcinoma in situ (DCIS) undergoing breast conservation surgery (BCS), guidelines advise a margin width of at least 2mm, with studies demonstrating decreased recurrence risk compared to narrower margins. However, limited data exist establishing if this margin is appropriate in mastectomies, and specifically for nipple-sparing mastectomy (NSM). Consequently, we evaluated the margins of DCIS patients undergoing NSM and resulting oncologic outcomes. A single-institution retrospective review was performed in patients with DCIS or DCIS with microinvasion (DCIS + MI) undergoing NSM from April 2010 to December 2021. Patient and tumor characteristics, margin status, treatment, and outcomes information were collected. The association between margins and local-regional (LRR) and distant recurrence (DR) were examined. 161 patients were included, comprising 284 NSM (164 therapeutic, 120 prophylactic). 153 patients had DCIS and 8 had DCIS + MI. Most patients had hormone sensitive, 123 (76.4%), and nuclear grade 2, 72 (44.7%), disease. In total, 35 (21.7%) patients had positive or <2mm margins. Of these, 21 (60%) involved the anterior margin. At a median follow-up of 45 months (range 0-151), 2.5% (n = 4) had a LRR and .6% (n = 1) had a DR. Of patients with a recurrence, only 2 had positive or <2mm margins, 1 had received endocrine therapy, and none received adjuvant radiation. No specific margin status was found to correlate with recurrence for patients with DCIS or DCIS + MI undergoing NSM, with an altogether low recurrence risk. Overall, this suggests that recommended DCIS margins in BCS doesn't necessarily apply in NSM, where margins of <2mm may be acceptable.

Impact of government-issued financial incentive to medical facilities on management of secondary dysmenorrhea.

In April 2020, the Japanese government introduced a Specific Medical Fee for managing secondary dysmenorrhea (SD). This initiative provided financial incentives to medical facilities that provide appropriate management of SD with hormonal therapies. We aimed to assess how this policy affects the management processes and outcomes of patients with SD. Using a large Japanese administrative claims database, we identified outpatient visits of patients diagnosed with SD from April 2018 to March 2022. We used an interrupted time-series analysis and defined before April 2020 as the pre-introduction period and after April 2020 as the post-introduction period. Outcomes were the monthly proportions of outpatient visits due to SD and hormonal therapy among women in the database and the proportions of outpatient visits for hormonal therapy and continuous outpatient visits among patients with SD. We identified 815 477 outpatient visits of patients diagnosed with SD during the pre-introduction period and 920 183 outpatient visits during the post-introduction period. There were significant upward slope changes after the introduction of financial incentives in the outpatient visits due to SD (+0.29% yearly; 95% confidence interval, +0.20% to +0.38%) and hormonal therapies (+0.038% yearly; 95% confidence interval, +0.030% to +0.045%) among the women in the database. Similarly, a significant level change was observed after the introduction of continuous outpatient visits among patients with SD (+2.68% monthly; 95% confidence interval, +0.87% to +4.49%). Government-issued financial incentives were associated with an increase in the number of patients diagnosed with SD, hormonal therapies, and continuous outpatient visits.
