RESUMEN
Cancer continues to pose a significant global health challenge, with gastrointestinal (GI) cancers among the most prevalent and deadly forms. These cancers often lead to high mortality rates and demand the use of potent cytotoxic chemotherapeutics. For example, 5-fluorouracil (5-FU) forms the backbone of chemotherapy regimens for various GI cancers, including colorectal cancer. While these chemotherapeutics efficiently kill cancer cells, they frequently cause off-target effects such as chemotherapy-induced mucositis (CIM), characterized by debilitating symptoms like pain, nausea, and diarrhoea, necessitating medical intervention. In this study, we elucidated the potential of melatonin and misoprostol to reduce 5-FU-induced small intestinal mucositis. Morphological and cellular changes in the jejunum, along with colonic faecal water content were quantified in rats as markers for CIM. Additionally, the effects of melatonin were investigated in vitro on 5-FU treated murine intestinal organoids. The results showed that melatonin prevented villus atrophy in the rat jejunal mucosa and upheld cell viability in murine intestinal organoids. In contrast, misoprostol alone or in combination with melatonin did not significantly affect CIM caused by 5-FU. These in vivo and in vitro experiments provided promising insights that melatonin may be used as a preventive and/or adjuvant combination therapy to prevent and reduce CIM, holding the potential to enhance cancer treatment outcomes and improve patient quality-of-life.

INTRODUCTION: The demand for effective and safe treatments of genitourinary syndrome (GSM) in post-menopausal women (PMW) is growing. Published data on the efficacy and safety of ospemifene (OSP) prompt an updated literature review to enlighten possible improvements in the GSM treatment. AREA COVERED: We searched articles published in English from 2010 to 2023 through Medline (PubMed) and Embase databases with Boolean terms: OSP, PMW, GSM, endometrium, breast cancer, cardiometabolic syndrome, bone metabolism, adherence to treatment, and patient satisfaction. We selected randomized controlled trials (RCTs) and observational and cross-sectional studies and completed the search manually. EXPERT OPINION: Of the 157 retrieved records, 25 primary studies met the inclusion criteria (15 regarding efficacy and safety, two for additional effects, and four for adherence and satisfaction with the OSP treatment). Seven RCTs involved nearly 5,000 patients, 10 out of 18 prospective observational studies 563, and six retrospective analyses 356,439. Evidence of OSP treatment in PMW with GSM relies on RCTs and remarkable real-world data. The 25 primary studies showcased the high clinical response to symptoms, the favorable safety profile of OSP with very few adverse events, a neutral impact on the endometrium, breast, bone, and thrombosis, and the possible improvement of cardiovascular risk factors.

OBJECTIVES: This TRIPLE study was aimed to evaluate the efficacy of polycarbophil vaginal gel (PCV) in treating symptoms of vaginal atrophy (VA) of peri- and post-menopausal women. MATERIALS AND METHODS: Sexually active women in peri- (n = 29) and post-menopause (n = 54) suffering from VA, were progressively enrolled and treated for 30 days with PCV. Those wishing to continue (n = 73) were treated for additional 180 days. PCV was administered as one application twice a week. The vaginal health index (VHI; range 5 to 25) and the visual analogue score (VAS range for 0 to 100 mm for each item) for vaginal dryness, irritation, and pain at intercourse, along with the global symptoms score (GSS; range 1 to 15) and treatment safety, were evaluated at baseline and after 30 days. In those continuing the treatment an evaluation was performed after additional 180 days. RESULTS: Women in peri and post-menopause were of 48.7 ± 3.3 years and 57.5 ± 5.7 years old., respectively. At baseline all outcomes were significantly worse (p<0.002) in postmenopausal group, except the VHI (p < 0.056). After 30 days VHI increased (p < 0.001) of 4.1 ± 0.5 (mean ± SE), and 5.1 ± 0.4 in peri- and post-menopausal women respectively. VAS of vaginal dryness decreased (p < 0.001) of -24.4 ± 3.6, and -52.7 ± 2.6 (p < 0.001), VAS of irritation decreased (p<0.001) of -18.6 ± 4.4 and -47.8 ± 3.2, VAS of pain decreased (p < 0.001) of -26.2 ± 4.3 and -55.6 ± 3.1 and the GSS decreased (p < 0.001) of -3.9 ± 0.3, and -4.9 ± 0.2, in peri and post-menopausal women, respectively. All the modifications were significantly greater (p < 0.001)(p < 0.032 for GSS) in postmenopausal women, and after 30 days all outcomes were similar in the two groups of women. In comparison to baseline, after 210 days of treatment VHI increased of 7.7 ± 0.3 (p < 0.001), VAS of vaginal dryness decreased of -53.6 ± 1.9 (p < 0.001) VAS of irritation of -42.6 ± 1.4 (p < 0.001) VAS of pain of -46.7 ± 2.3 (p < 0.001) and the GSS of -6.5 ± 0.2 ± 0.2 (p < 0.001). All outcomes improved (p < 0.001) over the values observed after 30 days of treatment (p < 0.001). No side effect was reported. CONCLUSIONS: In peri- and post-menopausal women PCV administration rapidly improves VA symptoms, and its prolongation up to 6 months further increases its efficacy.

Background and Objectives: Genitourinary syndrome, previously defined as vulvovaginal atrophy, manifests with signs and symptoms deriving from estrogen diminution in the female genitourinary tract. Stable ozonides are derivatives of artemisinin found to be stable against strong basic and acidic conditions. Vitamin E is an important antioxidant diminishing the output of reactive oxygen species in the oxidation of fats and the emanation of free radicals, reducing cellular injury and aging. The primary aim of the present study was to assess the positive effects of an ozonide plus a vitamin E acetate-based compound (Ozoile) on genitourinary syndrome symptom relief after a maximum of 20 days of treatment. Materials and Methods: The inclusion criteria for patients' enrollment were women of child-bearing age or in menopause reporting genitourinary syndrome's related symptoms, such as pain, burning, a bad smell, dyspareunia, dryness, itching, bleeding, and nervousness. The exclusion criteria were Sjogren's syndrome and patients administered retinoic acid, an agent that causes mucosal dryness. Participants completed a questionnaire before and after 20 days of treatment. Results: The incidence of pain decreased from 16.7% to 11.8% (p-value < 0.0001). In addition, the mean symptom intensity decreased from 2.10 to 0.87 (p-value < 0.0001). Dryness was the most frequent pre-treatment symptom and decreased from 85.5% to 53.8% (p-value < 0.0001) (mean: 2.21 vs. 0.90; p-value < 0.0001). Conclusions: Ozoile was effective in reducing most gynecologic symptoms related to genitourinary syndrome. However, further studies are needed to compare its effect with other standards of care.

Diabetic cognitive impairment is a common complication in type 2 diabetes. Berberine (BBR) is an isoquinoline alkaloid that has been shown to have neuroprotective effects against diabetes. This study aimed to investigate the effect of BBR on the gray and white matter of the brain by using magnetic resonance imaging (MRI) and to explore the underlying mechanisms. The study used diabetic db/db mice and administered BBR (50 and 100 mg/kg) intragastrically for twelve weeks. Morris water maze was applied to examine cognitive function. T2-weighted imaging (T2WI) was performed to assess brain atrophy, and diffusion tensor imaging (DTI) combined with fiber tracking was conducted to monitor the structural integrity of the white matter, followed by histological immunostaining. Furthermore, the protein expressions of the phosphatidylinositol 3-kinase (PI3K)/ protein kinase B (AKT)/ glycogen synthase kinase-3ß (GSK-3ß) were detected. The results revealed that BBR significantly improved the spatial learning and memory of the db/db mice. T2WI exhibited ameliorated brain atrophy in the BBR-treated db/db mice, as evidenced by reduced ventricular volume accompanied by increased hippocampal volumes. DTI combined with fiber tracking revealed that BBR increased FA, fiber density and length in the corpus callosum/external capsule of the db/db mice. These imaging findings were confirmed by histological immunostaining. Notably, BBR significantly enhanced the protein levels of phosphorylated AKT at Ser473 and GSK-3ß at Ser9. Collectively, this study demonstrated that BBR significantly improved the cognitive function of the diabetic db/db mice through ameliorating brain atrophy and promoting white matter reorganization via AKT/GSK-3ß pathway.

OBJECTIVE: The aim of this study was to demonstrate whether lasofoxifene improves vaginal signs/symptoms of genitourinary syndrome of menopause. METHODS: Two identical, phase 3 trials randomized postmenopausal women with moderate to severe vaginal symptoms to oral lasofoxifene 0.25 or 0.5 mg/d, or placebo, for 12 week. Changes from baseline to week 12 in most bothersome symptom, vaginal pH, and percentages of vaginal parabasal and superficial cells were evaluated. These coprimary endpoints were analyzed using analysis of covariance, except superficial cells, which were analyzed by the nonparametric, rank-based Kruskal-Wallis test. RESULTS: The two studies enrolled 444 and 445 women (mean age, ~60 y), respectively. Coprimary endpoints at week 12 improved with lasofoxifene 0.25 and 0.5 mg/d greater than with placebo ( P < 0.0125 for all). Study 1: most bothersome symptom (least square mean difference from placebo: -0.4 and -0.5 for 0.25 and 0.5 mg/d, respectively), vaginal pH (-0.65, -0.58), and vaginal superficial (5.2%, 5.4%), and parabasal (-39.9%, -34.9%) cells; study 2: most bothersome symptom (-0.4, -0.5), vaginal pH (-0.57, -0.67), and vaginal superficial (3.5%, 2.2%) and parabasal (-34.1%, -33.5%) cells. Some improvements occurred as early as week 2. Most treatment-emergent adverse events were mild or moderate and hot flushes were most frequently reported (lasofoxifene vs placebo: 13%-23% vs 9%-11%). Serious adverse events were infrequent and no deaths occurred. CONCLUSIONS: In two phase 3 trials, oral lasofoxifene 0.25 and 0.5 mg/d provided significant and clinically meaningful improvements in vaginal signs/symptoms with a favorable safety profile, suggesting beneficial effects of lasofoxifene on genitourinary syndrome of menopause.

BACKGROUND: Despite the gold standard treatment for genitourinary syndrome of menopause (GSM) is based on the use of local or systemic estrogen-containing products, the typical long-term side effects of hormonal treatments and, most importantly, the contraindications in patients with history of breast and endometrial neoplasms do limit in some extent its use. As hyaluronic acid and some highly purified botanicals have clearly demonstrated their anti-inflammatory and mucosa-protecting properties, we have tested, in women with GSM, a class II vaginal medical device containing hyaluronate gel and a mucoadhesive active enriched with purified alkylamides from Zanthoxylum bungeanum, triterpenes from Centella asiatica and high molecular weight polysaccharides from Tamarindus indica. METHODS: Our single-center, open-label, prospective and observational study was conducted on 50 menopausal women enrolled at the Department of Maternal-Fetal Medicine at Umberto I Polyclinic Hospital in Rome, Italy. Gel administration lasted 150 days and was performed daily for the first 12 days and every 48 hours for the remaining 138 days. Clinical evaluations were performed at baseline and after 12, 57 and 150 days. Besides product safety, main outcomes of our study were: 1) vaginal health (by Vaginal Health Index score [VHI]); 2) sexual quality of life (by Female Sexual Distress Scale [FSDS]); and 3) percentage of women declaring regular sexual activity. RESULTS: The product was safe with no specific adverse events reported. It significantly improved VHI (about 5% after 57 days and 8% after 150 days), FSDS (about 7% after 57 days and 10% after 150 days), and sexual activity (about 20% after 150 days). It also reduced dryness, dyspareunia, burning, itching, and dysuria incidence, respectively by about 18%, 14%, 14%, 27% and 11% after 150 days. CONCLUSIONS: In women with GSM, the intravaginal administration of a hyaluronate-based gel enriched with purified botanical actives endowed with anti-inflammatory and mucosal-protecting properties, reduced painful sensation during sexual acts and increased regular sexual activity.

OBJECTIVE: This study aims to compare the effects of vaginal estrogen and hyaluronic acid on vulvovaginal atrophy. PATIENTS AND METHODS: This randomized controlled study included a total of 300 patients, with 150 patients in each group (Group E and Group H). The VHI score was determined based on a pre-treatment evaluation conducted by a gynecologist. After one month of receiving vaginal estrogen in Group E and vaginal hyaluronic acid in Group H, the patients were re-evaluated by their physicians. RESULTS: A statistically significant difference was found between the pre- and post-treatment VHI scores in Group E and Group H (p = 0.000; p = 0.000). No statistical difference was found between Group E and Group H in terms of treatment efficacy (p = 0.712). The pre- and post-treatment complaints of dryness, itching, dyspareunia, burning, and dysuria were found to be statistically significant in Group E and Group H (p = 0.000; p = 0.000; p = 0.000; p = 0.000; p = 0.000 in Group E, respectively) (p = 0.000; p = 0.000; p = 0.000; p = 0.000; p = 0.000 in Group H, respectively). No statistical difference was observed regarding dyspareunia, dysuria, and burning complaints (p = 0.632; p = 0.106; p = 0.128, respectively). However, hyaluronic acid was found to be significantly more effective for itching complaints (p = 0.002), while estrogen was found to be significantly more effective for dryness complaints (p = 0.012). CONCLUSIONS: Hyaluronic acid and estrogen were equally effective in vaginal treatment. Hyaluronic acid may be preferred for patients in whom hormonal therapy is contraindicated or for those who prefer non-hormonal therapy.

Background: Vulvovaginal atrophy (VVA) is a common condition and a silent epidemic affecting many postmenopausal women who suffer from it in silence. This study aimed to evaluate the effect of Citrus aurantium vaginal cream on vaginal atrophy in postmenopausal women. Methods: This single-group pretest-posttest quasi-experimental study was conducted on 30 postmenopausal women who were referred to the Gynecology Clinic of Imam Khomeini Hospital in the city of Noor, Iran, from June to November 2020. Citrus aurantium vaginal cream was administered to women diagnosed with vaginal atrophy (based on subjective symptoms of atrophy, descriptive evaluation of the vagina, vaginal pH measurement, and degree of vaginal maturation determined by vaginal smear) every night in the first two weeks and every other night for the second two weeks. Data were collected using the scale of subjective symptoms of vaginal atrophy; descriptive evaluation checklist of vaginal mucosa; laboratory results registration form (vaginal maturation index, vaginal maturation value, and vaginal pH) before the intervention and two and four weeks after the intervention. Data were analyzed using SPSS software (version 24) through the analysis of variance with repeated measurements, and LSD post-hoc test. A P value less than 0.05 (P<0.05) was considered statistically significant. Results: Citrus aurantium vaginal cream improved subjective symptoms of vaginal atrophy (P<0.001), reduced the score of descriptive evaluation of vaginal mucosa (P<0.001), decreased vaginal pH (P<0.001), and increased vaginal maturity (P<0.001). Conclusions: The results showed that citrus aurantium vaginal cream could improve the symptoms of vaginal atrophy without causing serious complications. However, further studies with a control group are suggested to confirm the findings of this study.Trial Registration Number: IRCT20200215046494N.

Objective: To analyze and summarize the clinical and pathological characteristics, management, and efficacy of patients with vulvar lichen sclerosus (VLS) through a single center large sample study, and preliminarily to explore the frequency of maintenance treatment medication for VLS. Methods: The clinical data of VLS patients in Obstetrics and Gynecology Hospital of Fudan University from 2018 to 2021 were retrospectively collected. The clinicopathological characteristics (patients' age, course of disease, complicated disease history, family history, symptoms, signs and pathology), treatment and effects were retrospectively analyzed. The patients in the maintenance treatment stage were followed up regularly to explore the minimum frequency of individual medication to maintain the stability of the disease. Results: (1) General situation: a total of 345 patients with VLS were included in this study. The average age was (50.4±14.7) years (ranged from 8 to 84 years old), prevalence was highest in the 50-59 years group (30.1%, 104/345). Immune diseases occurred in 18.6% (33/177) of patients, 24.3% (43/177) of patients had allergic skin diseases, and 5.6% (10/177) of the patients' immediate family members had chronic vulvar pruritus or vulvar hypopigmentation. (2) Clinical features: the most common symptom was vulvar pruritus (96.1%, 196/204) among 204 patients with recorded symptoms. The most common sign was hypopigmentation of the vulva (96.3%, 206/214). The most common involved sites were labia minora (70.3%, 142/202), labia majora (67.8%, 137/202), and labial sulcus (59.4%, 120/202). The cumulative number of sites involved in 62 vulvar atrophy patients (2.7±1.1) was significantly higher than that in 152 non-atrophy patients (2.2±1.0; t=3.48, P=0.001). The course of vulvar atrophy was (9.3±8.5) years, which was significantly longer than that of non-atrophy patients [(6.6±5.6) years; t=2.04, P=0.046]. (3) Pathological features: among the 286 patients with electronic pathological sections, the most common pathological feature in the epidermis was epithelial nail process passivation (71.3%, 204/286). The common pathological features in the dermis were interstitial collagenization (84.6%, 242/286), and inflammatory cell infiltration (73.8%, 211/286). (4) Treatment: 177 patients received standardized treatment after diagnosis and were followed up regularly in our hospital. In the initial treatment stage, 26.0% (46/177) of the patients were treated with 0.05% clobetasol propionate cream, and 74.0% (131/177) of the patients were treated with 0.1% mometasone furoate ointment. The complete remission rates of the two methods were respectively 80.4% (37/46) and 74.0% (97/131), and there was no statistically significant difference (χ²=0.76, P=0.385). During maintenance treatment, 27.1% (48/177) of the patients took the medication twice a week, 35.0% (62/177) took the medication once a week, and 37.9% (67/177) took the medication once every 10 days. During follow-up after 6 months of maintenance treatment, there were no patients with recurrence of pruritus or progression of vulvar signs. Conclusions: The majority of VLS patients have itching, hypopigmentation, involvement of labia minora and labia majora, progressive atrophy, and inflammatory infiltration of dermis. Local treatments of mometasone furoate and clobetasol propionate have good initial therapeutic effects. The frequency exploration of individualized maintenance treatment could minimize the occurrence of adverse reactions when ensuring the stability of the patients' condition.

INTRODUCTION: Acne vulgaris is a common skin condition that affects a significant percentage of adolescents, with scarring being one of its permanent complications. This study aims to compare the efficacy and safety of using botulinum toxin type A (BTA) in combination with cross-linked and non-cross-linked hyaluronic acid (HA) for the treatment of atrophic acne scars. METHOD: Our study is a randomized, double-blind clinical trial conducted on 16 patients with atrophic acne scars. The patients were randomly assigned to one of two groups: one group received a single session of BTA and crossed link HA combination, while the other group received two sessions of BTA and non-crossed link HA, 1 month apart. The patients were followed up at 3 and 6 months after baseline to evaluate the number and area of fine and large pores and spots, scar grading, patient satisfaction, and complications. RESULTS: The mean age of individuals in both the cross-linked HA and non-cross-linked HA groups was 32.75 ± 4.26 and 31.50 ± 8.48 years, respectively (p = 0.71). In terms of gender, three (37.5%) and seven (87.5%) individuals in the cross-linked and non-cross-linked HA groups were female, respectively (p = 0.11). There were no significant differences in the count and area of fine and large pores and spots between the two groups at baseline and the first follow-up session. However, in the second follow-up session, the non-cross-linked HA group had significantly better results than the cross-linked HA group in terms of large pores count and area (p = 0.01). In terms of changes over time, the non-cross-linked HA group showed significantly better improvements in the count and area of large pores compared to the cross-linked HA group (p = 0.03). Additionally, both groups experienced a significant decrease in the count and area of fine pores over time (p = 0.001), but the amount of changes was not statistically significant between the two groups (p = 0.06). Concerning acne grade, initially, 62.5% and 12.5% of cases in the cross-linked HA and non-cross-linked HA groups, respectively, had severe grades. However, in the last session, these percentages significantly decreased to 0% for both groups (p = 0.002 and 0.005, respectively). In terms of treatment complications, none of the patients experienced any adverse effects. CONCLUSION: The study demonstrated that both cross-linked HA and non-cross-linked HA were effective in reducing acne severity and improving the appearance of pores and spots. The treatments had similar effects on fine pores, spots, and overall acne severity. However, non-cross-linked HA appeared to have a better result on large pores compared to cross-linked HA.

OBJECTIVE: Treatment of bipolar disorder (BD) involves complexities especially when patients come with significant sensitivity to various psychotropic medications and comorbidities. The following cases aim to recapitulate and discuss some of such situations. CASES: Case 1: A 36-year-old man with intellectual development disorder and BD experienced catatonia, seizures, and hyperammonemia following valproate administration. Treatment involved electroconvulsive therapy (ECT) and a tailored medication regimen, ultimately leading to stability. Case 2: A 63-year-old man with long-standing BD exhibited resistance to lithium and valproate of late, having co-existing essential tremors and cerebellar atrophy. Multiple medication trials led to side effects, requiring ECT for symptom improvement, followed by a carefully adjusted maintenance regimen. CONCLUSION: Medication side effects can pose major challenges in treatment of BD. Comprehensive evaluation and monitoring are essential. ECT can prove valuable in such cases. There is pressing need to develop more safer treatment alternatives, especially considering the progressively ageing society.

INTRODUCTION: Vulvar lichen sclerosus (VLS) is characterized by progressive anatomical changes which become increasingly severe and irreversible. The objective of this study was to investigate if a "window of opportunity" exists in VLS, i.e., to assess if an early treatment may prevent disease progression and facilitate clearance of symptoms and/or signs. METHODS: This retrospective, cohort study included VLS patients treated for the first time with a topical corticosteroid, namely with mometasone furoate 0.1% ointment, for 12 weeks (2016-2021). Scoring of subjective symptoms (global subjective score, GSS, and dyspareunia) and clinical features (global objective score [GOS] and sclerosis-scarring-atrophy) was performed at baseline (T0) and at the control visit (T1). We assessed if the achievement of clearance in GSS, GOS, sclerosis-scarring-atrophy, or dyspareunia depended on the time elapsed between VLS onset and treatment initiation. RESULTS: Among the 168 patients (59.2 ± 13.2 years) included, the median time between VLS onset and first treatment was 14.0 months. At T1, 48.8% of patients achieved clearance of GSS, 28% of GOS and 11.9% of both GSS and GOS, 57.9% of dyspareunia, and 19.2% of sclerosis-scarring-atrophy. The logistic regression model showed that each 10-month increase in treatment initiation adversely affected the clearance of GSS while starting treatment within 6 months of disease onset was significantly associated with clearance of GOS and sclerosis-scarring-atrophy. CONCLUSION: Early treatment is crucial in determining a complete healing of VLS-related symptoms and signs, especially of tissue sclerosis-scarring-atrophy, which appear poorly responsive, or even unresponsive, after the earliest stages of the disease. Thus our findings provide evidence for a "window of opportunity" in VLS treatment.

PURPOSE: To investigate the predictors of macular chorioretinal atrophy, consisting of patchy atrophy (PA) at the macula and choroidal neovascularization (CNV)-related macular atrophy (CNV-MA), during treatment with ranibizumab or aflibercept for myopic CNV (mCNV) and its impact on visual outcomes. METHODS: This retrospective study included 82 eyes with treatment-naïve mCNV who were treated with pro re nata injections of ranibizumab or aflibercept. RESULTS: Nine eyes (11.0%) presented with macular PA at baseline (PA group), and 73 eyes (89.0%) did not (non-PA group). VA improved during the first year in the non-PA group; a similar trend was noted in the PA group until 3 months after initial treatment. This improvement was maintained until 24 months ( P < 0.001) in the non-PA group, but not in the PA group. In the PA group, macular chorioretinal atrophy progressed faster ( P < 0.0001), and CNV-MA was more frequent during the 2 years of treatments ( P = 0.04). Even non-PA group eyes sometimes developed CNV-MA (42% at Month 24) if they had a larger CNV and thinner subfoveal choroidal thickness at baseline, resulting in poorer visual prognosis ( P < 0.01). CONCLUSION: Macular PA at baseline was a risk factor for CNV-MA development and was associated with poor visual outcomes.

Acute exposure to nerve agents induces a peripheral cholinergic crisis and prolonged status epilepticus (SE), causing death or long-term brain damage. To provide preclinical data pertinent to the protection of infants and newborns, we compared the antiseizure and neuroprotective effects of treating soman-induced SE with midazolam (MDZ) versus tezampanel (LY293558) in combination with caramiphen (CRM) in 12- and 7-day-old rats. The anticonvulsants were administered 1 hour after soman exposure; neuropathology data were collected up to 6 months postexposure. In both ages, the total duration of SE within 24 hours after soman exposure was significantly shorter in the LY293558 plus CRM groups compared with the MDZ groups. Neuronal degeneration was substantial in the MDZ-treated groups but absent or minimal in the groups treated with LY293558 plus CRM. Loss of neurons and interneurons in the basolateral amygdala and CA1 hippocampal area was significant in the MDZ-treated groups but virtually absent in the LY293558 plus CRM groups. Atrophy of the amygdala and hippocampus occurred only in MDZ-treated groups. Neuronal/interneuronal loss and atrophy of the amygdala and hippocampus deteriorated over time. Reduction of inhibitory activity in the basolateral amygdala and increased anxiety were found only in MDZ groups. Spontaneous recurrent seizures developed in the MDZ groups, deteriorating over time; a small percentage of rats from the LY293558 plus CRM groups also developed seizures. These results suggest that brain damage can be long lasting or permanent if nerve agent-induced SE in infant victims is treated with midazolam at a delayed timepoint after SE onset, whereas antiglutamatergic treatment with tezampanel and caramiphen provides significant neuroprotection. SIGNIFICANCE STATEMENT: To protect the brain and the lives of infants in a mass exposure to nerve agents, an anticonvulsant treatment must be administered that will effectively stop seizures and prevent neuropathology, even if offered with a relative delay after seizure onset. The present study shows that midazolam, which was recently approved by the Food and Drug Administration for the treatment of nerve agent-induced status epilepticus, is not an effective neuroprotectant, whereas brain damage can be prevented by targeting glutamate receptors.

Depot medroxyprogesterone acetate causes a hypo-estrogenic state in over half of users although clinical vaginal atrophy causing superficial dyspareunia is thought rarely to occur. This is a case series of ten women using depot medroxyprogesterone acetate who presented with superficial dyspareunia and clinical vaginal atrophy. The women were treated with vaginal estriol cream and their contraception was discontinued or changed. All patients had either a complete resolution of symptoms or a substantial improvement at follow-up, and the clinical and laboratory findings of vaginal atrophy had resolved. This case series demonstrates that vaginal atrophy may occur more frequently than previously thought.

Genitourinary syndrome of menopause is a common, under-reported, and undertreated chronic progressive condition requiring long-term treatment. Hypoestrogenism in the urogenital tissues is associated with bothersome dyspareunia, vulvovaginal symptoms, overactive bladder, and frequent urinary tract infections. Vaginal hormone therapies, including vaginal estrogen and intravaginal dehydroepiandrostenedione, are safe and effective and improve symptoms and clinical findings. Systemic hormone therapy treats vulvovaginal atrophy less effectively than vaginal hormone therapies with increased stress and urge urinary incontinence. Oral ospemifene effectively treats vaginal dryness and dyspareunia. Clinicians need to ask about symptoms of genitourinary syndrome of menopause, confirm the diagnosis, and suggest appropriate treatment options.

Objective: To analyze and summarize the clinical and pathological characteristics, management, and efficacy of patients with vulvar lichen sclerosus (VLS) through a single center large sample study, and preliminarily to explore the frequency of maintenance treatment medication for VLS. Methods: The clinical data of VLS patients in Obstetrics and Gynecology Hospital of Fudan University from 2018 to 2021 were retrospectively collected. The clinicopathological characteristics (patients' age, course of disease, complicated disease history, family history, symptoms, signs and pathology), treatment and effects were retrospectively analyzed. The patients in the maintenance treatment stage were followed up regularly to explore the minimum frequency of individual medication to maintain the stability of the disease. Results: (1) General situation: a total of 345 patients with VLS were included in this study. The average age was (50.4±14.7) years (ranged from 8 to 84 years old), prevalence was highest in the 50-59 years group (30.1%, 104/345). Immune diseases occurred in 18.6% (33/177) of patients, 24.3% (43/177) of patients had allergic skin diseases, and 5.6% (10/177) of the patients' immediate family members had chronic vulvar pruritus or vulvar hypopigmentation. (2) Clinical features: the most common symptom was vulvar pruritus (96.1%, 196/204) among 204 patients with recorded symptoms. The most common sign was hypopigmentation of the vulva (96.3%, 206/214). The most common involved sites were labia minora (70.3%, 142/202), labia majora (67.8%, 137/202), and labial sulcus (59.4%, 120/202). The cumulative number of sites involved in 62 vulvar atrophy patients (2.7±1.1) was significantly higher than that in 152 non-atrophy patients (2.2±1.0; t=3.48, P=0.001). The course of vulvar atrophy was (9.3±8.5) years, which was significantly longer than that of non-atrophy patients [(6.6±5.6) years; t=2.04, P=0.046]. (3) Pathological features: among the 286 patients with electronic pathological sections, the most common pathological feature in the epidermis was epithelial nail process passivation (71.3%, 204/286). The common pathological features in the dermis were interstitial collagenization (84.6%, 242/286), and inflammatory cell infiltration (73.8%, 211/286). (4) Treatment: 177 patients received standardized treatment after diagnosis and were followed up regularly in our hospital. In the initial treatment stage, 26.0% (46/177) of the patients were treated with 0.05% clobetasol propionate cream, and 74.0% (131/177) of the patients were treated with 0.1% mometasone furoate ointment. The complete remission rates of the two methods were respectively 80.4% (37/46) and 74.0% (97/131), and there was no statistically significant difference (χ²=0.76, P=0.385). During maintenance treatment, 27.1% (48/177) of the patients took the medication twice a week, 35.0% (62/177) took the medication once a week, and 37.9% (67/177) took the medication once every 10 days. During follow-up after 6 months of maintenance treatment, there were no patients with recurrence of pruritus or progression of vulvar signs. Conclusions: The majority of VLS patients have itching, hypopigmentation, involvement of labia minora and labia majora, progressive atrophy, and inflammatory infiltration of dermis. Local treatments of mometasone furoate and clobetasol propionate have good initial therapeutic effects. The frequency exploration of individualized maintenance treatment could minimize the occurrence of adverse reactions when ensuring the stability of the patients' condition.

INTRODUCTION: The aim of the study was to evaluate functional and anatomical changes in type 1 and type 2 naïve macular neovascularization (MNV) patients treated with brolucizumab injections up to 1 year of treatment (week 48). METHODS: Thirty-eight eyes of 38 patients with active MNV were enrolled at the Ophthalmology Clinic of the University "G. d'Annunzio," Chieti-Pescara, Italy. All patients were scheduled for brolucizumab intravitreal injections as per label, according to the standard HAWK and HARRIER trials guidelines. Enrolled patients underwent complete ophthalmic evaluation, including optical coherence tomography (OCT) and OCT angiography. All measurements were evaluated at baseline and then monthly up to week 48. The main outcome measures were changes in best-corrected visual acuity (BCVA); central macular thickness (CMT); subfoveal choroidal thickness (SCT); pigment epithelial detachment presence and maximum height (PEDMH); intraretinal fluid (IRF) presence, subfoveal subretinal fluid (SSRF) presence and maximum height, macular atrophy area, and neovascular membrane flow area in the slab extending from the outer retina to choriocapillaris (ORCC flow). RESULTS: CMT and BCVA significantly changed in both groups over time. ORCC flow and SCT significantly reduced in both groups over time. Atrophy areas increased from 0 to 0.17 mm2 and from 0 to 0.23 mm2 in type 1 MNV and type 2 MNV patients, respectively. PEDMH reduced in type 1 MNV from 138 µm at T0 to 96 µm at T5. Changes in fluids were noted, with SSRF thickness reduction and IRF changes in both groups. CONCLUSION: Our one-year results of treatment confirm brolucizumab to be efficient and safe in both type 1 and type 2 MNV patients, proposing novel OCT parameters as possible biomarkers of treatment.

BACKGROUND: Thalamic volume loss is known to be associated with clinical and cognitive disability in progressive multiple sclerosis (PMS). OBJECTIVE: To investigate the treatment effect of ibudilast on thalamic atrophy more than 96 weeks in the phase 2 trial in progressive(MS Secondary and Primary Progressive Ibudilast NeuroNEXT Trial in Multiple Sclerosis [SPRINT-MS]). METHODS: A total of 231 participants were randomized to either ibudilast (n = 114) or placebo (n = 117). Thalamic volume change was computed using Bayesian Sequence Adaptive Multimodal Segmentation tool (SAMseg) incorporating T1, fluid-attenuated inversion recovery (FLAIR), and fractional anisotropy maps and analyzed with a mixed-effects repeated-measures model. RESULTS: There was no significant difference in thalamic volumes between treatment groups. On exploratory analysis, participants with primary progressive multiple sclerosis (PPMS) on placebo had a 0.004% greater rate of thalamic atrophy than PPMS participants on ibudilast (p = 0.058, 95% confidence interval (CI) = -0.008 to <0.001). Greater reductions in thalamic volumes at more than 96 weeks were associated with worsening multiple sclerosis functional composite (MSFC-4) scores (p = 0.002) and worsening performance on the symbol digit modality test (SDMT) (p < 0.001). CONCLUSION: In a phase 2 trial evaluating ibudilast in PMS, no treatment effect was demonstrated in preventing thalamic atrophy. Participants with PPMS exhibited a treatment effect that trended toward significance. Longitudinal changes in thalamic volume were related to worsening of physical and cognitive disability, highlighting this outcome's clinical importance.
