Effects of COVID-19 or vaccines for SARS-COV-2 on sperm parameters: A systematic review and meta-analysis.

This systematic review and meta-analysis assessed the effects of SARS-Cov-2 and mRNA vaccines on male reproduction.

Correspondence: semen parameters in men who recovered from covid-19 - a systematic review and meta-analysis.

A recent systematic review with meta-analysis performed by Tiwari et al. (Middle East Fertil Soc J 26:44, 2021) suggested that coronavirus disease 2019 (COVID-19) affects both semen parameters and sexual hormones. However, we have observed a few inconsistencies in their systematic review methods and their synthesis of results (meta-analysis), which would have impacted their results.

Adjuvant platinum-based chemotherapy for early stage cervical cancer.

Background: This is the second updated version of the original Cochrane review published in the Cochrane Library 2009, Issue 3. Most women with early cervical cancer (stages I to IIA) are cured with surgery or radiotherapy, or both. We performed this review originally because it was unclear whether cisplatin-based chemotherapy after surgery, radiotherapy or both, in women with early stage disease with risk factors for recurrence, was associated with additional survival benefits or risks.

Laparoscopy versus laparotomy for FIGO stage I ovarian cancer.

Background: This is an updated version of the original review that was first published in the Cochrane Database of Systematic Reviews 2008, Issue 4. Laparoscopy has become an increasingly common approach to surgical staging of apparent early-stage ovarian tumours. This review was undertaken to assess the available evidence on the benefits and risks of laparoscopy compared with laparotomy for the management of International Federation of Gynaecology and Obstetrics (FIGO) stage I ovarian cancer.

[Meta analysis of the use of Bayesian networks in breast cancer diagnosis].

The aim of this study was to determine the accuracy of Bayesian networks in supporting breast cancer diagnoses.

Meta-analysis identifies tumor necrosis factor-alpha and interleukin-1 beta as diagnostic biomarkers for bacterial and aseptic meningitis.

Background: Meningitis is a complex and severe acute infectious disease of the central nervous system and is caused mainly by bacteria and viruses. However, the distinction between aseptic and bacterial meningitis can be difficult for clinicians because the symptoms and the results of laboratory assays are often similar and overlapping, particularly when the use of antibiotics is administered prior to examining the cerebrospinal fluid.

Methods: We determined the accuracy of tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) for the differential diagnosis between bacterial and aseptic meningitis.

Accuracy of serum human epididymis protein 4 in ovarian cancer diagnosis: a systematic review and meta-analysis.

Objective: A systematic review was performed to estimate the accuracy of human epididymis protein 4 (HE4) assay in the diagnosis of ovarian tumors.

Methods: A comprehensive search of the MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, IBECS, BIOSIS, Web of Science, SCOPUS, congress abstracts, and Grey literature (Google scholar; British Library) from January 1990 to April 2013 was conducted. Studies that evaluated HE4 levels for the diagnosis of ovarian tumors and compared them with paraffin-embedded sections as the diagnostic standard were included.

Accuracy of cerebrospinal fluid Aβ(1-42) for Alzheimer's disease diagnosis: a systematic review and meta-analysis.

Background: Alzheimer's disease (AD) is the most common cause of dementia, accounting for 65-70% of all dementia cases.

Objective: We performed a systematic review and meta-analysis to estimate the accuracy of cerebrospinal fluid Aβ1-42 for the diagnosis of AD. A comprehensive search of the Cochrane Library, MEDLINE, LILACS, Grey literature, and EMBASE was performed for papers published from January 1990 to August 2013.

A randomized clinical trial on the effects of remote intercessory prayer in the adverse outcomes of pregnancies.

The scope of this article was to investigate whether intercessory prayer (IP) influences the adverse outcomes of pregnancies. A double-blind, randomized clinical trial was conducted with 564 pregnant women attending a prenatal public health care service. The women were randomly assigned to an IP group or to a control group (n = 289 per group).
