Observational Study
Effectiveness of the antiviral medications azvudine and nirmatrelvir-ritonavir in treating COVID-19 in patients with hematological malignancies.
Patients with Hematological Malignancies (HM) are at a high risk of mortality from Coronavirus disease 2019 (COVID-19). The available antivirals were different between China and other countries. In China, azvudine was obtained for emergency use to treat adult COVID-19 patients with moderate symptoms in July 2022. While nirmatrelvir-ritonavir was well-known and used in many countries. The purpose of the present study was to assess whether there was any difference in the efficacy and safety of the two drugs. ⋯ The authors found no significant differences existed in outcome measures between patients with HM and COVID-19 who were treated with nirmatrelvir-ritonavir or azvudine.

Studies regarding serum Progesterone (P4) concentration and Clinical Pregnancy Rates (CPR) in fresh Embryo Transfer (ET) after Controlled Ovarian Stimulation Cycles (COS) remain inconclusive. To find a P4 cutoff point on fresh ET day associated with higher CPR, and to identify predictive factors of CPR and P4, the authors conducted a prospective cohort of 106 patients who underwent COS at a public IVF center. The luteal phase was supported with vaginal micronized progesterone (200 mg, 8/8h), beginning on oocyte retrieval day. ⋯ Women's age ≥ 40 years (OR = 0.0956; 95 % CI 0.0156-0.5851), poor response to COS (OR = 0.0964; 95 % CI 0.0155-0.5966), and follicles ≥ 10 mm (OR = 1.465; 95 % CI 1.013-2.117) were associated with the cutoff point. As the ROC curve was unsatisfactory, P4 ≥ 28.9 ng/mL should not be used to infer gestational success. In fresh ET, P4 concentration may merely reflect a woman's age and individual response to COS rather than being a reliable CPR predictor.

To demonstrate the clinical and radiographic results of revision knee arthroplasty using a modular system manufactured in Brazil. ⋯ This implant had 93.5 % survivorship (no cases of aseptic failure) and good results in 27 out of 31 knees (87 % of the surgeries).

The maternal mortality rate in developing countries, such as Brazil, has significantly increased since 2020. Obstetric Emergencies (OE) account for 72.5% of these deaths. A national survey was conducted in Brazil to evaluate how gynecologists and obstetricians deal with OE and identify the main difficulties regarding theoretical/practical knowledge and structural resources. ⋯ A high Maternal Mortality Ratio (MMR) may be related to disorganized healthcare systems, low implementation of risk classification protocols for the care of severe maternal and fetal conditions, and lack of access to continued/specific training programs. The Brazilian MMR is multifactorial. According to obstetricians, Brazilian health services include care teams, essential medications, obstetric centers, and clinical analysis laboratories, though they lack systematized processes and permanent professional training for qualified care of OE.

This controlled study investigated metabolic changes in non-vaccinated individuals with Long-COVID-19, along with their connection to the severity of the disease. The study involved 88 patients who experienced varying levels of initial disease severity (mild, moderate, and severe), and a control group of 29 healthy individuals. Metabolic risk markers from fasting blood samples were analyzed, and data regarding disease severity indicators were collected. ⋯ HDL-C and ferritin were identified as the leading factors predicted by disease severity. In conclusion, the decline in HDL-C levels and rise in ferritin levels seen in Long-COVID-19 individuals, largely influenced by the severity of the initial infection, could potentially play a role in the persistence and progression of Long-COVID-19. Hence, these markers could be considered as possible therapeutic targets, and help shape preventive strategies to reduce the long-term impacts of the disease.
