In this paper, we report general pharmacological profile and major biological activities of natural progesterone (P) and progestins. The aim of this article consists of synthesizing the principal aspects of pharmacology and metabolism of P and progestins related to the clinical consequences of their use.

We review scientific literature on the topic "Progestins", evaluating the most relevant data from original articles, reviews and meta-analyses.

Progestins represent a specific class of synthetic analogues of P clinically employed (alone or associated with estrogens) to manage several gynaecological conditions, for instance multiple abortions, luteal phase defect, premenstrual syndrome, abnormal uterine bleeding, endometriosis and menopause (for hormone replacement therapy). Besides their use in the field of contraception, many non-contraceptive benefits of estroprogestins are mostly due to the activities of progestins. Pharmacological characteristics, dosage and individual metabolism could be listed among the principal aspects influencing their clinical effects.

The choice of each progestin according to its pharmacological profile is crucial for the appropriate management of any gynaecological condition. An aware knowledge of these compounds is fundamental to hone medical practice.

Evaluate obstetric, epidemiological and social factors related to Postpartum Depression (PPD) and investigate possible risk factors related to this disorder, in puerperal women who had their childbirth and were referred to the hospital's High-Risk Outpatient Clinic.

A cross-sectional study from August-December/2019 was carried out. 171 puerperal women were analysed by filling out an epidemiological questionnaire and Edinburgh Postpartum Depression Scale (EPDS) form. Scores ≥10 were considered positive. Research on risk factors for postpartum depression was carried out.

29.8% of mothers had a score related with PPD. Breastfeeding without complication is protective against PPD ((p=0.002 and χ2=12.533). In contrast, not having a planned pregnancy (p=0.0175, χ2=5.717), having depression at any stage of life (p=0.013, χ2=6.237), depression during pregnancy (p≤0,0001, χ2=46,201) or having a family history of depression (p=0.001, χ2=10.527), are factors associated with the development of PPD. Moreover, just having depression during pregnancy was found to be a significant risk factor for the occurrence of PPD, increasing the risk of developing this pathology by 12 times (OR12.891).

Depression during pregnancy is an important risk factor for the development of PPD. This can easily be detected using the Edinburgh Postpartum Depression Scale and treated in a timely manner.

CIN2 is considered a biologically equivocal lesion falling between low and high grade cervical dysplasia, but it is often managed with cervical conization as a high-grade lesion. However, since cervical conization can lead to an increased risk of adverse obstetric events, it might be interesting to identify, by colposcopy, a subgroup of women with a low risk of "occult" CIN3 who could be managed with a "wait and see" approach.

All the women with CIN2 cervical biopsy from 1999 to 2019 were retrospectively identified. Their colposcopic patterns at the time of biopsy and the histopathological findings on the final cone specimen were compared.

Among the 354 women with CIN2 biopsy included, the overall CIN3+ lesion rate on final cone specimen was 21.4%. The rate of CIN3 on final specimen was higher in women with G2 colposcopy compared to G1 (27,2% vs 15.9%, p= 0.01). Among women with G1 colposcopy, the rate of CIN3+ lesions was significantly higher in women with fine punctation (p=0.02) while no differences in women with thin acetowhite epithelium or fine mosaic emerged.

In women with CIN2 biopsy, when a G2 pattern or G1 with fine punctation on colposcopy is detected, there is an increased risk of CIN3+ on final histology, therefore an excisional treatment should be preferred. Otherwise, in women with CIN2 biopsy and other G1 patterns on colposcopy, a "wait and see" approach could be considered.

Determine the optimal follicle size at trigger in clomiphene citrate-based IVF protocols.

This is a retrospective cohort study performed in at a single academic institution that included first IVF cycles with clomiphene citrate-based protocols at our center between 01/01/2013-03/31/2019. Patients were dichotomized by whether they had ≥2 follicles >20 mm on trigger day. Group A consisted of patients with <2 follicles >20 mm on trigger day and Group B consisted of patients with ≥2 follicles >20 mm on trigger day. The primary outcome was the number of mature oocytes retrieved. Secondary outcomes included pregnancy and live birth rates.

A total of 635 patients were included (Group A = 399 patients and Group B = 236 patients). The median (IQR) diameter of the largest follicle was 20.0 mm (19.0-21.0) in Group A and 22.7 mm (21.8-24.0) in Group B (p < 0.001). Among the entire cohort, mean number of oocytes retrieved was significantly higher in Group B (9.9 ± 6.5; RR 1.08 (95% CI 1.03-1.14)) compall ages combined.

There is an unmet clinical need to identify biomarkers to predict which non-small cell lung cancer (NSCLC) patients will benefit from immune checkpoint inhibitor (ICPI) treatment.

The purpose of this study was to draw a detailed time-to-treatment failure (TTF) curve with information on peripheral eosinophils during ICPI treatment for NSCLC, and to clarify whether eosinophil information can predict prolonged TTF.

In 259 patients with NSCLC treated with ICPI therapy, peripheral eosinophil counts and percentages at the time of each ICPI administration were evaluated in each patient from the beginning of ICPI treatment up to TTF. Univariable and multivariable analyses were performed to identify clinical factors that were associated with TTF.

When 180 patients receiving ICPI monotherapy were divided into three groups - "TTF≤6 weeks", "6 weeks<TTF≤24 weeks", and "24 weeks<TTF"- the rate of "5% or more within 6 weeks" was significantly different among the three groups. By univariable and multivariable analyses, "PS 0-1" and "immune-related adverse event excluding ICPI discontinuation", as well as "≥5% eosinophils within 6 weeks" and"≥330/μL eosinophils within 6 weeks", were significant favorable factors for TTF. In 79 patients treated with combination therapy of ICPI and chemotherapy, the rate of "5% or more within 12 weeks" was significantly different between"TTF≤12 weeks", and "12 weeks<TTF". However, the only significant favorable factor for TTF was "female gender".

In NSCLC patients treated with ICPI therapy, especially ICPI monotherapy, eosinophil measurements during treatment might provide information useful in predicting prolonged TTF.

Preliminary retrospective reports showed that zinc supplementation may decrease mortality in COVID-19 patients, postulating the potential therapeutic efficacy of zinc in the management of the disease.

We sought to summarize the studies published to date regarding the antiviral activity of zinc in COVID-19 patients.

A meta-analysis was performed to compare the outcomes of hospitalized patients receiving zinc supplementation and those treated with standard care. The primary outcome was survival to hospital discharge. Secondary outcomes were in-hospital mortality and length of stay in hospital or intensive care unit (ICU).

Data relating to 1474 patients included in four studies were analyzed. Survival to hospital discharge was 56.8% in the zinc group, compared to 75.9% in the non-zinc group (P=0.88). In-hospital mortality was 22.3% in the zinc group, compared to 13.6% for the standard care group (P=0.16). Length of hospital stay was 7.7(3.7) days in the zinc group and 7.2(3.9) days in the standard treatment group (P<0.001). Length of ICU stay was 4.9(1.7) days in the zinc group and 5.8(1.9) days in the standard care group (P=0.009).

Zinc supplementation did not have any beneficial impact on the course of COVID-19 evaluated as survival to hospital discharge and in-hospital mortality. The zinc-supplemented group had longer hospital and ICU lengths of stay. There is at present no evidence-based data to support routine zinc supplementation in COVID-19 patients.

Pre-gelatinization is one of the most common physical methods of starch modification, which involves heating to bring about significant changes in the nature of starch, such as high swelling, loss of crystallinity, solubility in cold water, and improved pasting.

The objective of this study is to evaluate the structural and physicochemical properties of starch from Neorautanenia mitis tubers, and determine the effect of pre-gelatinization on the functional properties of this starch.

Properties of the pre-gelatinized starch (NMPS), such as flow, swelling power, hydration capacity, pH, morphology, Fourier-infrared spectroscopy (FTIR), differential scanning calorimetry, and pasting characteristics, were compared with those of the native starch (NMNS).

Pre-gelatinized starch had good flow with the angle of repose at 33.69°. Carr's index was 10.90% and 7.50%, and the Hausner ratio was 1.12 and 1.05 for NMNS and NMPS, respectively. Both starches had neutral to near-neutral pH (7.00 and 6.04, respectively). T bond strength.

The results showed that pre-gelatinized starch from N. mitis tubers possesses high swelling and hydration abilities and significant pasting properties, and may be used as a disintegrant in solid dosage formulations and in products requiring low viscosities and bond strength.Vaccines are considered one of the most significant medical advancements in human history, as they have prevented hundreds of millions of deaths since their discovery; however, modern travel permits disease spread at unprecedented rates, and vaccine shortcomings like thermal sensitivity and required booster shots have been made evident by the COVID-19 pandemic. AS1842856 mouse Approaches to overcoming these issues appear promising via the integration of vaccine technology with biomaterials, which offer sustained-release properties and preserve proteins, prevent conformational changes, and enable storage at room temperature. Sustained release and thermal stabilization of therapeutic biomacromolecules is an emerging area that integrates material science, chemistry, immunology, nanotechnology, and pathology to investigate different biocompatible materials. Biomaterials, including natural sugar polymers, synthetic polyesters produced from biologically derived monomers, hydrogel blends, protein-polymer blends, and metal-organic frameworks, have emerged as early players in the field.
