Higher-Level Steatosis Is Associated with a Greater Decrease in Metabolic Dysfunction-Associated Steatoic Liver Disease after Eight Weeks of a Very Low-Calorie Ketogenic Diet (VLCKD) in Subjects Affected by Overweight and Obesity.

The most common form of chronic liver disease, recently defined as MASLD, is strongly linked to obesity and metabolic syndrome. Lifestyle changes are part of MASLD prevention. The very low-calorie ketogenic diet (VLCKD) is a useful option for treating MASLD and reducing liver steatosis in patients with obesity. We assessed whether a greater degree of steatosis could have a positive or negative impact on how well 8 weeks of using the VLCKD improve steatosis and fibrosis in a patient population of overweight and obese individuals. Anthropometric parameters, along with changes in hormone and metabolic biomarkers, were also assessed both before and after the dietary change. The study population included 111 overweight (14.41%) or obese subjects (85.59%) aged between 18 and 64 years; the 75 women and 36 men involved were not taking any medicine. In both the raw (0.37 95% CI 0.21; 0.52) and the multivariate models (model a: 0.439 95% CI 0.26; 0.62; model b: 0.437 95% CI 0.25; 0.63), there was a positive and statistically significant correlation between the CAP delta value and the CAP before using the VLCKD. Additionally, the liver stiffness delta was found to be positively and statistically significantly correlated with liver stiffness before the use of the VLCKD in both models: the multivariate model (model a: 0.560 95% CI 0.40; 0.71; model b: 0.498 95% CI 0.34; 0.65) and the raw model (0.52 95% CI 0.39; 0.65). Systolic and diastolic blood pressure, insulin resistance (measured by HOMA-IR), insulin, HbA1c, fasting blood glucose, total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides, BMI, waist circumference, and fat mass, were all decreased (p < 0.001) following the use of the VLCKD. However, following the use of the VLCKD, there was an increase in vitamin D levels. (p < 0.001). We found that using the VLCKD for 8 weeks has a greater effect on improving steatosis and fibrosis in subjects who initially have more severe forms of these conditions.

Female Sexual Dysfunction in Diabetes: Mechanisms, Diagnosis and Treatment.

Female sexual dysfunction (FSD) is an underinvestigated comorbidity of diabetes mellitus, often not evaluated in diabetes clinics. Diabetic women should be encouraged to talk about this topic by their diabetologist, because these problems could be comorbid to cardio-metabolic alterations, as it happens in the male counterpart. This review summarizes evidence on sexual dysfunction characteristics in diabetic women, exploring possible underlying pathogenic mechanisms. The role of hypoglycemic drugs in this context was also evaluated. To date, no specific questionnaire has been designed for the assessment of sexual dysfunctions in diabetic female patients but the use of colour-doppler ultrasound of clitoral arteries has been highlighted as a useful tool for the assessment of cardiovascular risk in these women. Similarly, no specific guidelines are available for the treatment of FSD in the diabetic population but patients should be supported to have a healthy lifestyle and, in the absence of contraindications, can benefit from already approved treatments for FSD.

Physical Activity and Female Sexual Dysfunction: A Lot Helps, But Not Too Much.

BACKGROUND: Research on the relationship between physical activity (PA) and female sexual dysfunction (FSD) is lacking. AIM: To investigate the clinical, psychological, and sexual correlates of PA in women with FSD. METHODS: A non-selected series of n = 322 pre- and post-menopausal patients consulting for FSD was retrospectively studied. Regular involvement in PA and its frequency (<1 hour/week: sedentary, 1-3 hours/week: active, 4-6 hours/week: very active, >6 hours/week: extremely active) were investigated with a specific question. OUTCOMES: FSDs, including HSDD (Hypoactive sexual desire disorder) and FGAD (Female genital arousal disorder), were diagnosed according to a structured and clinical interview. Participants underwent a physical examination and a clitoral Doppler ultrasound, and were asked to complete the Female Sexual Function Index, Female Sexual Distress Scale-Revised, Body Uneasiness Test, and Middlesex Hospital Questionnaire. RESULTS: At multivariate analysis, women engaging in PA (67.4%, n = 217) scored significantly higher in several Female Sexual Function Index domains - including desire, arousal and lubrication - and showed lower sexual distress and lower resistance of clitoral arteries, as compared to sedentary women. A significant, inverse association between PA and HSDD was observed. Mediation analysis demonstrated that the negative association between PA and HSDD was partly mediated by body image concerns (Body Uneasiness Test Global severity index), psychopathological symptoms (Middlesex Hospital Questionnaire total score) and sexual distress (Female Sexual Distress Scale-Revised score). These latter 2 factors also partly mediated the association between PA and a reduced risk of FGAD, whilst a lower BMI was a full mediator in the relationship between PA and FGAD. Finally, extreme PA was associated with significantly worse scores in several psychosexual parameters (i,e, sexual satisfaction and histrionic/hysterical symptoms), even compared to a sedentary lifestyle. CLINICAL IMPLICATIONS: Women consulting for FSD may gain benefits on desire, arousal, lubrication and sex-related distress from regular PA; however, physicians should remain alert to the downsides of excessive exercise. STRENGTHS & LIMITATIONS: The main strength lies in the novelty of the findings. The main limitations are the cross-sectional nature, the clinical setting, the small sample size of the different PA groups, and the use of self-reported instruments for the evaluation of PA. CONCLUSION: In women with FSD, PA was associated with better sexual function and clitoral vascularization, lower sexual distress and reduced odds of HSDD and FGAD; the benefits of PA on sexuality were mediated by both psychological and organic determinants; excessive PA was related with a poor overall sexual function and with a low sexual satisfaction.

SHBG as a Marker of NAFLD and Metabolic Impairments in Women Referred for Oligomenorrhea and/or Hirsutism and in Women With Sexual Dysfunction.

PCOS is one of the most common endocrine disorders and NAFLD is one of its most dangerous metabolic consequences. The diagnosis of NAFLD is not a practical task and the condition is at risk of being overlooked. The use of simpler but still reliable surrogate markers is necessary to identify women with a high likelihood of NAFLD. The aim of this study was to evaluate the clinical correlates of NAFLD Liver Fat Score (NAFLD-LFS) in women with oligomenorrhea and/or hirsutism. Furthermore, the study aimed to evaluate whether, among the hormonal parameters evaluated in such women, possible hallmarks of NAFLD may be identified. To this purpose, 66 women who attended our Outpatient Clinic for oligomenorrhea and/or hyperandrogenism were included in the study. In order to validate the results obtained in the first cohort, a second independent sample of 233 women evaluated for female sexual dysfunction (FSD) was analyzed. In cohort 1, NAFLD-LFS positively correlated with metabolic and inflammatory parameters. Among the hormone parameters, NAFLD-LFS showed no significant relationships with androgens but a significant negative correlation with SHBG (p<0.0001) that therefore appeared as a candidate hallmark for pathologic NAFLD-LFS. The ROC analysis showed a significant accuracy (81.1%, C.I.69.1-93.0, p <0.0001) for SHBG in identifying women with a pathological NAFLD-LFS. In particular, a SHBG 33.4 nmol/l was recognized as the best threshold, with a sensitivity of 73.3% and a specificity of 70.7%. In order to validate this SHBG as a marker of metabolic impairment possible related with the presence of NAFLD, we tested this threshold in cohort 2. FSD women with SHBG <33.4 nmol/l had worse metabolic parameters than women with SHBG ≥33.4 nmol/l and a significantly higher NAFLD-LFS even after adjusting for confounders (B=4.18 [2.05; 6.31], p=0.001). In conclusion, this study provides a new evidence in the diagnostic process of NAFLD, showing that the measurement of SHBG, which is routinely assessed in the workup of women referred for possible PCOS, could identify women at higher metabolic risk, thus detecting those who may deserve further targeted diagnostic assessment.

Safety and Efficacy of Convalescent Plasma in Elderly COVID-19 Patients: The RESCUE Trial.

OBJECTIVE: To assess the safety and efficacy of convalescent plasma (CP) transfusion in elderly people with moderate to severe coronavirus disease 2019 (COVID-19) living in a long-term care facility (LTCF). PATIENTS AND METHODS: Twenty-two consecutive elderly patients with COVID-19 infection living in an LTCF in Lombardy, Italy, who were given CP during May 15 to July 31, 2020, were enrolled in a prospective cohort study. Their clinical, instrumental, and laboratory parameters were assessed following the CP treatment. The overall mortality rate in this group was compared with that recorded in other LTCFs in Lombardy during the 3-month period from March to May 2020. RESULTS: Of the 22 patients enrolled, 68.2% (n=15) received 1 CP unit, 27.3% (n=6) received 2 units, and 4.5% (n=1) received 3 units. Of the CP units transfused, 76.7% (23/30) had a neutralizing antibody titer of 1:160 or greater. No adverse reactions were recorded during or after CP administration. Improvements in clinical, functional, radiologic, and laboratory parameters during the 14 days after CP transfusion were observed in all 19 patients who survived. Viral clearance was achieved in all patients by the end of follow-up (median, 66 days; interquartile range, 48-80 days). The overall mortality rate was 13.6% (3/22), which compared favorably with that in the control group (38.3% [281/733]; P=.02) and corresponded to a 65% reduction in mortality risk. CONCLUSION: Early administration of CP with an adequate anti-severe acute respiratory syndrome coronavirus 2 antibody titer to elderly symptomatic patients with COVID-19 infection in an LTCF was safe and effective in eliminating the virus, restoring patients' immunity, and blocking the progression of COVID-19 infection, thereby improving patients' survival. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04569188.

Low testosterone levels predict clinical adverse outcomes in SARS-CoV-2 pneumonia patients.

BACKGROUND: The pandemic of new severe acute respiratory syndrome (SARS) due to coronavirus (CoV) 2 (SARS-CoV-2) has stressed the importance of effective diagnostic and prognostic biomarkers of clinical worsening and mortality. Epidemiological data showing a differential impact of SARS-CoV-2 infection on women and men have suggested a potential role for testosterone (T) in determining gender disparity in the SARS-CoV-2 clinical outcomes. OBJECTIVES: To estimate the association between T level and SARS-CoV-2 clinical outcomes (defined as conditions requiring transfer to higher or lower intensity of care or death) in a cohort of patients admitted in the respiratory intensive care unit (RICU). MATERIALS AND METHODS: A consecutive series of 31 male patients affected by SARS-CoV-2 pneumonia and recovered in the respiratory intensive care unit (RICU) of the "Carlo Poma" Hospital in Mantua were analyzed. Several biochemical risk factors (ie, blood count and leukocyte formula, C-reactive protein (CRP), procalcitonin (PCT), lactate dehydrogenase (LDH), ferritin, D-dimer, fibrinogen, interleukin 6 (IL-6)) as well as total testosterone (TT), calculated free T (cFT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were determined. RESULTS: Lower TT and cFT were found in the transferred to ICU/deceased in RICU group vs groups of patients transferred to IM or maintained in the RICU in stable condition. Both TT and cFT showed a negative significant correlation with biochemical risk factors (ie, the neutrophil count, LDH, and PCT) but a positive association with the lymphocyte count. Likewise, TT was also negatively associated with CRP and ferritin levels. A steep increase in both ICU transfer and mortality risk was observed in men with TT < 5 nmol/L or cFT < 100 pmol/L. DISCUSSION AND CONCLUSION: Our study demonstrates for the first time that lower baseline levels of TT and cFT levels predict poor prognosis and mortality in SARS-CoV-2-infected men admitted to RICU.

Insight on the Intracrinology of Menopause: Androgen Production within the Human Vagina.

In this study, we investigated steroidogenic gene mRNA expression in human vaginas and verified the ability of human vagina smooth muscle cells (hvSMCs) to synthesize androgens from upstream precursor dehydroepiandrosterone (DHEA). As a readout for androgen receptor (AR) activation, we evaluated the mRNA expression of various androgen-dependent markers. hvSMCs were isolated from vagina tissues of women undergoing surgery for benign gynecological diseases. In these cells, we evaluated mRNA expression of several steroidogenic enzymes and sex steroid receptors using real time reverse transcription-polymerase chain reaction. Androgen production was quantified with liquid chromatography tandem-mass spectrometry (LC-MS/MS). In vaginal tissues, AR mRNA was significantly less expressed than estrogen receptor α, whereas in hvSMCs, its mRNA expression was higher than progestin and both estrogen receptors. In hvSMCs and in vaginal tissue, when compared to ovaries, the mRNA expression of proandrogenic steroidogenic enzymes (HSD3ß1/ß2, HSD17ß3/ß5), along with 5α-reductase isoforms and sulfotransferase, resulted as being more abundant. In addition, enzymes involved in androgen inactivation were less expressed than in the ovaries. The LC-MS/MS analysis revealed that, in hvSMCs, short-term DHEA supplementation increased Δ4-androstenedione levels in spent medium, while increasing testosterone and DHT secretion after longer incubation. Finally, androgenic signaling activation was evaluated through AR-dependent marker mRNA expression, after DHEA and T stimulation. This study confirmed that the human vagina is an androgen-target organ with the ability to synthesize androgens, thus providing support for the use of androgens for local symptoms of genitourinary syndrome in menopause.

Nomegestrol acetate/17beta-estradiol does not negatively alter the vascular resistance of clitoral arteries: a prospective, exploratory study.

The effect of nomegestrol acetate/estradiol (NOMAC/E2) on clitoral and uterine vascularization has never been evaluated. We aimed to investigate, in women consulting for contraceptive needs, the possible changes in clitoral and uterine arteries hemodynamic parameters after 6 months treatment with NOMAC/E2 as compared with other hormonal contraceptives (HCs). In this observational, prospective pilot study, ten women were enrolled. Color Doppler ultrasound was performed on the clitoral and uterine arteries at baseline and after 6 months treatment with NOMAC/E2 (n = 5) or other HCs (n = 5). NOMAC/E2 did not exert any significant effect on clitoral vascular resistance expressed by the pulsatility index (PI); conversely, treatment with other HCs significantly increased this parameter (p = 0.04). The change in clitoral PI between the two groups retained a statistically significant difference even after adjusting for age. In the NOMAC/E2 group, at follow-up, uterine artery PI and acceleration were significantly reduced (p = 0.04), whereas no significant differences were observed in the HCs group; however, the change in uterine artery parameters did not differ significantly between the two groups. NOMAC/E2, differently from other COCs, does not negatively alter the vascular resistance of clitoral arteries and appears as a good contraceptive choice to protect both cardiovascular and sexual health.

Obesity and hormonal contraception: an overview and a clinician's practical guide.

BACKGROUND: The growing prevalence of obesity among the fertile female population poses a considerable problem to contraceptive providers. Obese women, who are more at risk for venous thromboembolism and cardiovascular events due to their condition, might be at an even higher risk of developing thromboembolic events when on medical contraception. Combined hormonal contraceptives might be less effective in obese women and may lead to unacceptable metabolic side effects for this population. In addition, the lack of safety data for weight loss drugs and the higher risk for complications during and after pregnancy require a close surveillance of the fertility status of obese patients. OBJECTIVE: The aim of this narrative review is to summarize the available medical contraceptive options and to give the readers a practical guidance for a wise contraceptive choice with regards to obesity. METHODS: A general literature review of peer-reviewed publications on the topic "obesity and contraception" was performed using the PubMed database. RESULTS: Nowadays, there are many useful tools that help clinicians in choosing among the wide range of therapeutic possibilities, such as the World Health Organization (WHO) Medical Eligibility Criteria for contraceptive use. Furthermore, the great diversity of hormonal contraceptive formulations (combined hormonal formulations; progestin-only methods) and active substances (different estrogens and progestins) allow physicians to tailor therapies to patients' clinical peculiarities. CONCLUSION: Long-acting reversible contraceptives [progestin-only implants, levonorgestrel-intra-uterine devices (IUDs) and copper IUDs] and progestin-only methods in general are excellent options for many categories of patients, including obese ones. LEVEL OF EVIDENCE: V, narrative review.

Sexual Health in Menopause.

Sexual function worsens with advancing menopause status. The most frequently reported symptoms include low sexual desire (40-55%), poor lubrication (25-30%) and dyspareunia (12-45%), one of the complications of genitourinary syndrome of menopause (GSM). Declining levels of sex steroids (estrogens and androgens) play a major role in the impairment of sexual response; however, psychological and relational changes related with aging and an increase in metabolic and cardiovascular comorbidities should also be taken into account. Although first-line therapeutic strategies for menopause-related sexual dysfunction aim at addressing modifiable factors, many hormonal and non-hormonal, local and systemic treatment options are currently available. Treatment should be individualized, taking into account the severity of symptoms, potential adverse effects and personal preferences.

Psychosexual Correlates of Unwanted Sexual Experiences in Women Consulting for Female Sexual Dysfunction According to Their Timing Across the Life Span.

BACKGROUND: Comparative data on the psychopathologic and sexual correlates of unwanted sexual experiences (USEs) occurring during childhood, adolescence, or adult life are lacking. AIM: To investigate the prevalence of USEs in a setting of female sexual dysfunction (FSD) and to examine whether they are associated with different psychosexual parameters depending on the timing of occurrence. METHODS: A consecutive series of 200 heterosexual women attending our clinic for FSD was consecutively recruited. MAIN OUTCOME MEASURE: Patients underwent a structured interview and completed the Female Sexual Function Index, the Middlesex Hospital Questionnaire, the Female Sexual Distress Scale-Revised, the Body Uneasiness Test, and the Childhood Experience of Care and Abuse questionnaire. USEs were classified as occurring in adult life (≥17), adolescence (<17 and ≥14), or childhood (<14 years). RESULTS: 47 women (23.5%) reported USEs, occurring in childhood, adolescence, and adult life in 38.3% (n = 18), 31.9% (n = 15), and 29.8% (n = 14) of cases, respectively. We observed an association between history of lifetime USEs and indexes of psychopathology, specifically diagnosis of psychiatric diseases, use of psychiatric medications, and anxiety symptoms (Middlesex Hospital Questionnaire free-floating anxiety score). USEs were associated with lower orgasm ability (Female Sexual Function Index orgasm domain), higher sexually related distress levels (Female Sexual Distress Scale-Revised total score), and higher body image concerns (Body Uneasiness Test) including depersonalization symptoms. Notably, women exposed to USEs in adolescence reported a stronger impairment of arousal, orgasm, and satisfaction domains and higher sexual distress when compared to women without a history of USEs or reporting USEs in childhood. Women exposed to USEs in childhood exhibited higher body image concerns and depersonalization symptoms when compared to those not reporting USEs. CLINICAL IMPLICATIONS: USEs should be investigated in women consulting for FSD because patients who had USEs may require unique strategies to optimize the diagnostic and therapeutic work-up of their sexual symptoms. STRENGTH & LIMITATIONS: Our main contribution is that we addressed the different impacts of USEs depending on their timing across the life span. However, the cross-sectional nature of the study does not allow determination of the cause-and-effect nature of the associations, and the selectivity of the sample (women consulting for FSD) limits the generalizability of the results. CONCLUSION: The negative outcomes of USEs vary according to their timing of occurrence: adolescence appears as the most sensitive temporal window for USEs to exert their deleterious effects on female sexuality, whereas childhood USEs are more tightly related to a severe body uneasiness in adult life.

BRAF(V600E) assessment by pyrosequencing in fine needle aspirates of thyroid nodules with concurrent Hashimoto's thyroiditis is a reliable assay.

Detection of BRAF mutation in cytology specimens has been proposed as a diagnostic adjunctive tool in evaluation of thyroid nodules with indeterminate cytology findings. Concurrent papillary thyroid carcinoma and Hashimoto's thyroiditis (HT), a disease characterized by thyroid lymphocytic infiltration, is a frequent occurrence. A large lymphocytic infiltrate might reduce the sensitivity of methods employed to detect BRAF mutation in thyroid cytology specimens. To determine whether testing for BRAF mutational status in fine needle aspirates (FNA) is reliable also in the presence of HT lymphocytic infiltration, we assessed the BRAF status by direct sequencing and pyrosequencing in a series of FNAs with and without concomitant HT lymphocytic infiltration. We also performed the same assessment by pyrosequencing in the corresponding tissue samples. Pyrosequencing demonstrated to be more sensitive than direct sequencing. The percentage of mutant BRAF(V600E) alleles was higher in FNAs than in the corresponding tissues, probably because of the lower stromal contamination in FNA than in the sections. In the presence of lymphocytic infiltration, the percentage of mutant BRAF(V600E) alleles determined by pyrosequencing was higher in FNAs than in the corresponding tissue samples (P < 0.0001), indicating a minor lymphocytic contamination in FNA. The diagnostic value of BRAF(V600E) in inconclusive FNAs was not hampered by thyroid lymphocytic infiltration. These results indicate that BRAF(V600E) assessment by pyrosequencing is a reliable assay useful to refine inconclusive cytology of thyroid nodules also in the presence of concurrent HT.

BRAF mutation positive papillary thyroid carcinoma is less advanced when Hashimoto's thyroiditis lymphocytic infiltration is present.

BACKGROUND: Concomitant papillary thyroid cancer (PTC) and Hashimoto's thyroiditis (HT) is a frequent occurrence. Whether these two conditions are linked and whether PTC with concurrent HT has distinct clinicopathological characteristics are still debated issues. Lymphocytic infiltration is abundant in HT and might be relevant in the pathogenesis and progression of PTC. BRAF(V600E) mutation is associated with a more advanced PTC at diagnosis; however, its role in the clinicopathological characteristics of PTC with concurrent HT is unknown. DESIGN AND PATIENTS: We enrolled 146 patients with histological diagnosis of PTC. Microscopic assessment of histology samples was performed to identify the presence of lymphocytic infiltration. Detection of BRAF(V600E) was performed on cytology samples by both direct sequencing and pyrosequencing, and results were correlated with clinical parameters. RESULTS: Concurrent HT lymphocytic infiltration was associated with the female gender, smaller tumour size, a less frequent extracapsular extension and a lower grade of TNM staging. BRAF(V600E) was more frequent in PTC with concomitant lymphocytic infiltration. In PTC harbouring BRAF(V600E) , concurrent lymphocytic infiltration was still associated with the female gender, a less frequent extracapsular extension and a lower TNM staging. CONCLUSIONS: These results suggest that lymphocytic infiltration of HT is a protective factor against PTC progression, and it is independent of BRAF mutational status.

Metastatic renal cell carcinoma to the thyroid gland 24 years after the primary tumour.

Among the metastases to thyroid gland, metastases from renal cell carcinoma (RCC) are not rare and their frequent macroscopic looks are similar to primary thyroid tumours. We report an unusual case of thyroid metastases from renal carcinoma in a 72 -year-old man presented with a 1-year history of choking spells, stridor and dyspnoea. Patient underwent right nephrectomy for RCC, 24 years ago. In the present case, a right hemithyroidectomy was performed for a suspected anaplastic thyroid carcinoma. Histological examination showed a metastases of a clear cell renal carcinoma. Although the RCC showed an indolent biological behaviour, the late thyroid metastases have concurred with a poor prognosis and the patient died 5 months after surgery. The interest of this case lies in the long progression-free survival of the RCC preceded by the diagnosis of the thyroid nodule and the discrepancy between the clinical-radiological and the histological assessment.
