Observational Study
OBJECTIVE
To investigate safety and effectiveness of NOMAC-E2 and levonorgestrel-containing COCs (COC) in users over 40.
METHODS
In this large, observational study, new users of NOMAC-E2 and COC were recruited in Europe, Australia, and Latin America and followed-up questionnaires. Incidence of venous thromboembolism (VTE) was expressed as incidence rate (IR; events/10 women-years [WY]). Unintended pregnancy was expressed by the Pearl Index (PI; contraceptive failures/100 WY). Mood and weight changes were defined as mean changes in mood score and percentage of body weight.
RESULTS
Overall, 7,762 NOMAC-E2 and 6,059 COC users over 40 were followed-up. NOMAC-E2 showed no increased VTE risk compared to COC; confirmed events: 5 NOMAC-E2 (IR 5.9; 95% CI, 1.9-13.7) vs 4 COC (IR 5.9; 95% CI, 1.6-15.1). Unintended pregnancy did not differ substantially between cohorts; confirmed events: 4 NOMAC-E2 (PI 0.05; 95% CI, 0.01-0.13) vs 5 COC (PI 0.08; 95% CI, 0.03-0.18). No differential effect on mood and weight was observed between cohorts.
CONCLUSIONS
NOMAC-E2 can be considered a valid alternative to COC in perimenopausal women.

Observational Study
To investigate unintended pregnancy and changes in mood, acne, and weight in NOMAC-E2 vs levonorgestrel-containing COC (COC) users under 25 years. In this large, observational study, new users (first-ever users of an eligible COC or restarting with the same or a new eligible COC after a break of at least 2 months) of NOMAC-E2 and COC were recruited in 12 countries in Europe, Australia, and Latin America and followed up questionnaires for up to 2 years. Unintended pregnancy was expressed by the Pearl Index (PI; contraceptive failures/100 women-years). Crude (HR) and adjusted hazard ratios (HR) were calculated. Mood and acne changes were defined as change of score from baseline. Weight change was defined as percent change of body weight. Overall, 12,829 NOMAC-E2 users and 17,095 COC users under 25 were followed-up. The risk of unintended pregnancy was statistically significantly lower in the NOMAC-E2 cohort; confirmed events: 30 NOMAC-E2 (PI 0.24; 95% CI, 0.16-0.35) vs 94 COC (PI 0.51; 95% CI, 0.41-0.62). The HR for unintended pregnancy comparing NOMAC-E2 to COC was 0.47 (95% CI, 0.31-0.71) and the HR was 0.52 (95% CI, 0.34-0.78). No differential effect on acne, mood, and weight was observed between cohorts. NOMAC-E2 shows a significantly better contraceptive effectiveness in young women and has no differential effect on acne, mood, and weight compared to COC.

Review
Purpose: In this study we aimed to estimate the effectiveness of pharmacological, nutraceutical, and phytopharmaceutical treatments on CRF. Methods: Ovid MEDLINE, Ovid Embase, Ovid Psych info, CINHAHL and Cochrane Library databases were searched up to 30 September 2021. Randomized controlled trials of pharmacological, nutraceutical and phytopharmaceutical interventions for treatment of CRF for at least one week duration and have used valid tool to assess severity of CRF as a primary or secondary outcome were considered. Results: 32 eligible studies (4896 patients) were reviewed. For the overall meta-analysis, the random effect models yielded the treatment effect (95% CI) of −0.29 (−0.48,−0.09), p < 0.001. The meta-analysis did not show significant reduction of CRF with treatment with ginseng (n = 6), guarana (n = 3), megestrol (n = 2), mistletoe (n = 3), psychostimulants (n = 14), SSRI/antidepressants (n = 2). Corticosteroids (n = 2) showed significant reduction in CRF with treatment effects of 0.94 (−1.21, −0.67), p <0.0001, respectively. Conclusions: In this study, overall meta-analysis of all studies demonstrates significant reduction of CRF using Pharmacological, Nutraceutical and Phytopharmaceutical interventions with a pooled standardized treatment effect of −0.29. Metanalysis of Corticosteroids studies showed significant reduction in CRF. Further studies are needed.

Randomized Controlled Trial
Comparison of the effect of oral megestrol acetate with or without levonorgestrel-intrauterine system on fertility-preserving treatment in patients with early-stage endometrial cancer: a prospective, open-label, randomized controlled phase II trial (ClinicalTrials.gov NCT03241914).
OBJECTIVE
To evaluate the effect of levonorgestrel-releasing intrauterine system (LNG-IUS) plus oral megestrol acetate (MA) as fertility-preserving treatment in patients with early-stage endometrial cancer (EEC).
METHODS
In this single-center, phase II study with open-label, randomized and controlled design, young patients (18-45 years) diagnosed with primary EEC were screened, who strongly required fertility-preserving treatment. Patients were randomly assigned (1:1) into MA group (160 mg oral daily) or MA (160 mg oral daily) plus LNG-IUS group. Pathologic evaluation on endometrium retrieved by hysteroscopy was performed every 3 months. The primary endpoint was complete response (CR) rate within 16 weeks of treatment. The secondary endpoints were CR rate within 32 weeks of treatment, adverse events, recurrent and pregnancy rate.
RESULTS
Between July 2017 and June 2020, 63 patients were enrolled and randomly assigned. Totally 56 patients (26 in MA group; 28 in MA + LNG-IUS group) were included into primary-endpoint analyses. The median follow-up was 31.6 months (range, 3.1-94.0). No significant difference in 16-week CR rate were found between MA and MA + LNG-IUS groups (19.2% vs. 25.0%, p=0.610; odds ratio=1.40; 95% confidence interval=0.38-5.12), while the 32-week CR rates were also similar (57.1% and 61.5%, p=0.743), accordingly. More women in MA + LNG-IUS group experienced vaginal hemorrhage (46.4% vs. 16.1%; p=0.012) compared with MA group. No intergroup difference was found regarding recurrence or pregnancy rate.
CONCLUSION
Compared with MA alone, the addition of LNG-IUS may not improve the early CR rate for EEC, and may produce more adverse events instead.

Cachexia, a complex disorder that results in depletion of adipose tissue and skeletal muscle, is driven by anorexia, metabolic abnormalities and inflammation. There are limited therapeutic options for this syndrome. Previous evidence has demonstrated that increasing adipose tissue may improve quality of life and survival outcomes in cachexia. Cisplatin, as a chemotherapy drug, also causes cachexia during antitumor therapy due to its adverse effects. To establish a rat model of cachexia, the animals were intraperitoneally treated with cisplatin at doses of 1, 2 and 3 mg/kg, and the rats that responded to cisplatin at the optimal dose were used to test the effect of nomegestrol acetate (NOMAc). Rats that were assessed to be sensitive to cisplatin were randomly grouped and intragastrically administered vehicle, 5 or 10 mg/kg megestrol acetate (MA) or 2.5, 5 or 10 mg/kg NOMAc. The body weights and food consumption of the rats were assessed. Serum IL-6 and TNF-α levels were assessed using ELISA. The protein expression levels of adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), peroxisome proliferator activated receptor γ (PPARγ), fatty acid synthase (FASN) and sterol regulatory element-binding protein-1 (SREBP-1) from inguinal white adipose tissue (iWAT) and epididymal white adipose tissue (eWAT) were evaluated using western blotting. The optimal way to establish a chemotherapy-induced rat model of cachexia demonstrated in the present study was to intraperitoneally administer the rats with 2 mg/kg cisplatin for 3 consecutive days. NOMAc (2.5, 5 mg/kg) and MA (10 mg/kg) were able to significantly ameliorate the loss of body weight in the cisplatin-induced cachectic rats. NOMAc significantly reduced the serum levels of TNF-α at 10 mg/kg. Morphologically, iWAT atrophy, with a remarkable reduction in adipocyte volume, was observed in the cisplatin-induced cachectic rats, but the effects were reversed by administering 5, 10 mg/kg NOMAc or 10 mg/kg MA. Furthermore, 2.5 mg/kg NOMAc markedly reduced the protein expression levels of the lipolysis genes HSL and ATGL, and 5 mg/kg NOMAc markedly enhanced the protein expression levels of adipogenesis genes, including FASN, SREBP-1 and PPARγ in iWAT but not in eWAT. NOMAc was demonstrated to improve cachexia at lower doses compared with MA. Overall, NOMAc is likely to be a promising candidate drug for ameliorating cancer cachexia induced by cisplatin.

Review
Currently, whole uterus and bilateral tubal resection and oophorectomy is the main treatment of cervical mullerian adenosarcoma. However, young patients generally wish to retain reproductive function. The clinical data of a patient with cervical mullerian adenosarcoma, who underwent fertility preservation surgery were collected. A 13-year-old girl with abnormal vaginal bleeding and a 1.0 cm flocculent echogenicity in the lower part of the uterine cavity to the cervical canal and a cervical mass of about 61 mm×37 mm was found in the pelvic MRI. After initial diagnosis of dysfunctional uterine bleeding in adolescence and cervical blood clot, the patient was treated with artificial cycle treatment, but her symptoms did not improve. Then she was transferred to the Third Xiangya Hospital of Central South University for uninjured virgin membrane hysteroscopy and cervical mass electrotomy, but a few pedicles remained after the operation, and the pathology suggested a cervical mullerian adenosarcoma. Because the patient was young and had not yet given birth, she was treated with primary IAP regimen of chemotherapy and subcutaneously injected with gonadotropin-releasing hormone analogue (GNRH-A) once every 28 days (6 times in total) to protect the ovarian function. After the chemotherapy, she was treated with uninjured virgin membrane hysteroscopy and pedicle electrotomy of cervical mullerian adenosarcoma. After the operation, she received chemotherapy with IAP regimen for 5 times. After discharge, she was treated with megestrol 200 mg per day for 3 years. During 5 years of regular follow-up, no abnormality was seen. Cervical mullerian adenosarcoma in non-sexual women is easily misdiagnosed as ovulation dysfunction abnormal uterine bleeding. The necessity of hysteroscopy should be emphasized, and for patients with low-grade early-stage lesions who wish to retain fertility, local resection could be chosen, but attention is paid to lifelong follow-up to exclude long-term recurrence.

Megestrol acetate dispersible tablets with a 5-HT3 receptor antagonist and dexamethasone 5-HT3 receptor antagonist plus dexamethasone, can better control chemotherapy-induced nausea and vomiting: a randomized controlled study.
BACKGROUND
A reasonable and effective control of chemotherapy-induced nausea and vomiting (CINV) plays an important role in the comprehensive treatment of cancer. Megestrol belongs to the 17α-hydroxyprogesterone derivative and is a highly effective synthetic progesterone. Recorded in the instructions may improve appetite and cachexia in patients with advanced tumors. In recent years, clinical practice and small sample studies have shown that megestrol combined with chemotherapy can improve CINV. This randomized controlled trial aimed to evaluate the clinical efficacy and safety of megestrol acetate combined with a 5-Hydroxytryptamine (5-HT3) receptor antagonist and dexamethasone in patients with CINV.
METHODS
Patients with malignant tumors who were treated with cisplatin-containing chemotherapy in our hospital from September 2018 to December 2019 were enrolled. A total of 120 patients were selected and randomly assigned to receive either megestrol acetate dispersible tablets with a 5-HT3 receptor antagonist and dexamethasone (megestrol group) or a 5-HT3 receptor antagonist plus dexamethasone (control group). Megestrol acetate dispersible tablets: 160 mg orally every morning from the day of chemotherapy until it lasts for ten days. Abstract IV of the quality-of-life scale for cancer patients in China was used to assess the quality of life (QOL) of the participants. All adverse reactions during chemotherapy were assessed according to the CTCAE 4.03 evaluation standard issued by the National Cancer Institute and divided into five grades according to severity.
RESULTS
For the control of nausea, the rates of complete prevention were significantly higher in the megestrol group than in the control patients during the delayed [53.3% (31/60) 30.0% (18/60), P=0.012] and overall [40.0% (24/60) 15.0% (9/60), P=0.002] observation periods. Moreover, the megestrol combination treatment group also achieved markedly higher rates of complete remission of vomiting than the control group during the delayed observation period [76.7% (46/60) 51.7% (31/60), P=0.001], achieving an overall higher proportion of remission during the study period [68.3% (41/60) 46.6% (28/60), P=0.0016].
CONCLUSIONS
The triple antiemetic protocol using megestrol acetate with a 5-HT3 receptor antagonist plus dexamethasone can improve CINV symptoms caused by highly emetogenic chemotherapy (HEC) with cisplatin, with an excellent control effect and few adverse reactions, especially for delayed CINV.

Levonorgestrel-releasing intrauterine device plus metformin, or megestrol acetate plus metformin for fertility-sparing treatment of atypical endometrial hyperplasia and early endometrial carcinoma: a prospective, randomized, blind-endpoint design trial protocol.
BACKGROUND
Endometrial adenocarcinoma (EC) is the fifth most common cancer in women worldwide, standard treatment for EC includes hysterectomy, but it results in the loss of reproductive function. Thus, conservative treatment for these patients is strongly demanded, progestin therapy is widely accepted as the main fertility-sparing treatment for young women with endometrial hyperplasia with atypia (EHA) and well-differentiated endometrioid endometrial cancer. This trial will investigate the effectiveness of conservative treatment for obese women with early-stage EC.
METHOD AND DESIGN
This will be an open-label, 2-armed, randomized, phase-II single-center trial of LNG-IUD plus metformin or megestrol acetate (MA) plus metformin. A total of 88 participants will be randomly assigned into 2 treatment arms in a 1:1 ratio. Clinical, laboratory, ultrasound and radiology data, will be collected at baseline, and then at 3, 6, 9, 12, 18, and 24 months. EC biomarkers will be collected at baseline. The primary aim is to determine the efficacy of a levonorgestrel-releasing intrauterine device (LNG-IUD) plus metformin, or megestrol acetate (MA) plus metformin in achieving pathological complete response (pCR) at 12 months, as well as post-treatment pregnancy outcomes and recurrence rate. The secondary aims are to predict the response to an LNG-IUD plus metformin and MA plus metformin via clinical, blood, and tissue predictive biomarkers.
CONCLUSIONS
Prospective evidence for conservative treatment of EC is limited. New methods to achieve better CR rates with fewer side effects are needed. This trial will investigate the effectiveness of LNG-IUD plus metformin, and MA plus metformin, in obese women with early-stage EC, providing a non-surgical treatment option for these patients.

Meta-Analysis Review
BACKGROUND
Fifteen percent of patients with endometrial cancer (EC) have advanced stage disease or develop a recurrence. Progestins have been applied as systemic treatment for decades, but there is limited evidence on response prediction with biomarkers and toxicity.
OBJECTIVES
To review the response and toxicity of progestin therapy and stratify response to progesterone receptor (PR) expression and tumour grade.
SEARCH STRATEGY
We used the search terms 'Endometrial cancer', 'Progestins', 'Disease progression', 'Recurrence' and related terms in Pubmed, Embase and Cochrane databases.
SELECTION CRITERIA
Studies on patients with advanced stage or recurrent EC treated with progestin monotherapy were included. Studies on adjuvant therapy, with fewer than ten cases and with sarcoma histology were excluded.
DATA COLLECTION AND ANALYSIS
Evaluation for bias was performed with the Revised Cochrane RoB2 tool for randomised studies and the ROBINS-I tool for non-randomised studies. A random effects meta-analysis was performed with the overall response rate (ORR), clinical benefit rate and toxicity as primary outcome measures.
MAIN RESULTS
Twenty-six studies (1639 patients) were included. The ORR of progestin therapy was 30% (95% CI 25-36), the clinical benefit rate was 52% (95% CI 42-61). In PR-positive EC, the ORR was 55%, compared with 12% in PR-negative disease (risk difference 43%, 95% CI 15-71). Severe toxicity occurred in 6.5%.
CONCLUSIONS
Progestin therapy is a viable treatment option in patients with advanced stage and recurrent EC with low toxicity and high ORR in PR-positive disease. The role of PR expression in relation to progression-free survival and overall survival is unclear.

Baicalein modulates mitochondrial function by upregulating mitochondrial uncoupling protein-1 (UCP1) expression in brown adipocytes, cytotoxicity, and computational studies.
BACKGROUND
Obesity, fatty liver, type 2 diabetes, and Non-alcoholic fatty liver disease (NAFLD) are all metabolic diseases caused by excess food consumption. Existing drug molecules had negative side effects and caused other diseases to develop (Orlistat causes angioedema, and menstrual irregularities; megestrol acetate causes hypertension, and insomnia). By enhancing lipid consumption and increasing nonshivering thermogenesis, targeting mitochondrial uncoupling protein-1 (UCP1) expression in adipocytes could be an auspicious treatment strategy against obesity or metabolic disorders associated with obesity.
METHODS
We used previously produced UCP1-A-GFP reporter cell lines in this investigation to find new pharmacological compounds against obesity or metabolic syndrome, which we then tested in cellular analysis, cytotoxicity, mitochondrial function, mitochondrial DNA quantification, mitochondrial ATP production, and in-silico models.
RESULTS
Baicalein was discovered to play a critical role in obesity prevention via altering mitochondrial function. Baicalein lowers ATP generation while increasing considerable UCP1 gene expression in brown adipocytes. As a result, cellular thermogenesis is boosted. The HEK293T cell line is harmless by baicalein. The investigation by the in-silico study revealed drug-protein interaction and UCP1 binding. Thus, our research clarifies baicalein's therapeutic role in metabolic and obesity-related illnesses via modulating mitochondrial activity (Supplementary Fig. 2).
CONCLUSIONS
Further studies are required in both murine and human models to understand the full mechanism of action by mitochondrial modulation. Drug development investigation also requires to development of a precise formulation.
