In December 2019 a novel coronavirus emerged in Wuhan, China causing many cases of severe pneumonia. World Health Organization (WHO) named this disease Coronavirus Disease 2019 (COVID-19). The infection has rapidly spread across China to many other countries, and on March 12, 2020 the WHO declared pandemic outbreak of COVID-19. As of May 16, 2020, COVID-19 has been diagnosed in more than 4,490,000 patients, associated to 305,976 deaths worldwide; in Italy 224,760 COVID-19 cases have been reported with 31,763 deaths. The main routes of transmission are respiratory droplets and direct contact with infected people, so numerous prevention strategies are employed to mitigate the spread of disease, including social distancing and isolation. The aim of this narrative review is to underline gender differences in epidemiology, etiopathogenesis, risk factors, clinical presentation, diagnosis, prognosis and mortality of patients infected with SARS-CoV-2. Currently data on the sex indicators for admitted or deceased patients are only available, but there is no analysis about other gender indicators. The data considered in our study are the only currently available in the literature, but it is appropriate to implement a specific analysis with all gender indicators to identify appropriate strategies. Moreover, the evaluation of a health service efficiency is a key element to define gender outcomes. Knowing the gender differences in COVID-19 outbreak would be a fundamental tool to understand the effects of a health emergency on individuals and communities as well as to carry out effective and equitable policies, public health measures and targeted solutions.

Background: Low back pain (LBP) is an emerging disease. This review aims to investigate the role of gender-related factors in the diagnosis, clinical, and surgical management of LBP. Methods: From January 2002 to March 2023, EMBASE, SCOPUS, OVID-MEDLINE, Google Scholar, PubMed, and Web of Science were searched to identify relevant papers for further analysis. Results: Fifteen papers were included in this review. Sex- and gender-related differences were analyzed regarding the following points: (1) LBP epidemiology; (2) LBP physiopathology; (3) conservative management of LBP; (4) major vertebral surgery for LBP. The conservative treatment of LBP highlights that women claim services later in terms of poorer health status than men. In the postoperative phase, female patients show worse LBP, quality of life, and disability, but equal or greater interval change, compared with male patients complaining of lumbar degenerative disease. Conclusions: LBP epidemiology and clinical outcomes, following conservative and surgical management of patients complaining of back pain, might depend on both sex- and gender-related factors. It is mandatory to assess gender-related indicators in patients referred to LBP and address them to improve their clinical outcomes and quality of life.

Background and Objectives: Sex and gender-related differences may influence the outcome of patients undergoing total hip arthroplasty (THA). The present paper aims to depict the importance of sex and gender-related issues in the perioperative management of patients undergoing THA to improve clinical outcomes and prevent postoperative complications. Materials and Methods: From January 2002 to August 2022, OVID-MEDLINE, EMBASE, SCOPU S, Web of Science, Google Scholar, and PubMed were searched to identify relevant studies for further analysis. The search strategy included the following terms: ((“gender-related differences” [MeSH Terms] OR “sex-related differences” [All Fields]) OR (“gender indicators” [MeSH Terms] OR “sex” [All Fields])) AND (“total hip arthroplasty” [MeSH Terms] OR (total hip replacement [All Fields])). Results: Twenty-eight papers were included in this current concepts review. Sex and gender-related differences were analyzed with regard to the following points: (1) surgical approach, robotic surgery, scar cosmesis, and implant choice; (2) postoperative clinical outcome and complications; (3) sexual activity after THA; and (4) psychological status and daily functional requirements. The data analysis showed that female patients need more specific attention in the preoperative, intraoperative, and postoperative phases to improve clinical and functional outcomes, reduce complications risk, and manage patient satisfaction. Conclusions: THA outcomes may be influenced by sex and gender-related factors which should be carefully assessed and addressed in patients undergoing surgery to improve the postoperative outcomes of patients’ satisfaction and reduce postoperative complications that can differ between the two sexes.

Purpose: The exact nature of sex and gender differences in knee osteoarthritis (OA) among patient candidates for total knee arthroplasty (TKA) remains unclear and requires better elucidation to guide clinical practice. The purpose of this investigation was to survey physician practices and perceptions about the influence of sex and gender on knee OA presentation, care, and outcomes after TKA. Methods: The survey questions were elaborated by a multidisciplinary scientific board composed of 1 pain specialist, 4 orthopedic specialists, 2 physiatrists, and 1 expert in gender medicine. The survey included 5 demographic questions and 20 topic questions. Eligible physician respondents were those who treat patients during all phases of care (pain specialists, orthopedic specialists, and physiatrists). All survey responses were anonymized and handled via remote dispersed geographic participation. Results: Fifty-six physicians (71% male) accepted the invitation to complete the survey. In general, healthcare professionals expressed that women presented worse symptomology, higher pain intensity, and lower pain tolerance and necessitated a different pharmacological approach compared to men. Pain and orthopedic specialists were more likely to indicate sex and gender differences in knee OA than physiatrists. Physicians expressed that the absence of sex and gender-specific instruments and indications is an important limitation on available studies. Conclusions: Healthcare professionals perceive multiple sex and gender-related differences in patients with knee OA, especially in the pre- and perioperative phases of TKA. Sex and gender bias sensitivity training for physicians can potentially improve the objectivity of care for knee OA among TKA candidates.

Coronavirus Disease-2019 (COVID-19) is the worst worldwide pandemic with more than 12,000,000 cases and 560,000 deaths until 14^th July 2020. Men were more infected by COVID-19 than women, and male subjects with underlying conditions, including diabetes, hypertension, and cardiovascular diseases developed a severe form of the affection, with increased mortality rate. Many factors can contribute to the disparity in disease outcomes, such as hormone-specific reaction and activity of X-linked genes, which modulate the innate and adaptive immune response to virus infection. Until now, only the Remdesivir was approved by FDA (Food Drug Administration) for COVID-19 treatment, although several clinical trials are ongoing worldwide also on other drugs. In this review, we analyzed published studies on several drugs (chloroquine or hydroxychloroquine, remdesivir, favipiravir, lopinavir-ritonavir in combination, tocilizumab, plasma, and immunoglobulins) with some efficacy to COVID-19 in humans, and evaluated if there were a gender analysis of the available data. In our opinion, it is essential to report data about COVID-19 disaggregated by sex, age, and race, because the knowledge of gender differences is fundamental to identify effective and customized treatments to reduce hospitalizations, admissions to intensive care units, and mortality.

The present study aims to depict the importance of gender-related factors in the subjective perception of spine deformity in adolescents undergoing posterior instrumented fusion for scoliosis. Patients undergoing posterior spinal instrumentation and fusion (PSF) for idiopathic adolescent scoliosis (AIS) were recruited. The following data were recorded: gender, age, parents’ civil status, Tegner Activity Scale (TAS), body mass index (BMI), concomitant diseases, and history of neuropsychological disorders. Each patient underwent clinical and radiological evaluations according to the protocol used at our institution. All the patients were assessed before surgery using the following Patient-Reported Outcome Measures (PROMs): the Italian version of the revised Scoliosis Research Society—22 patient questionnaire (SRS-22R), the Quality-of-Life Profile for Spinal Deformities (QLPSDs) questionnaire, and the Spinal Appearance Questionnaire (SAQ). The present study recruited 80 patients (male: 19, female: 61). A significant correlation was observed between BMI, TAS, and subjective perception scores. A worse deformity perception was observed in female patients and patients with divorced parents. Gender-related factors impact the subjective perception of spine deformity in patients undergoing PSF for AIS. Specific assessment and correction are needed to improve postoperative outcomes in these patients.
