Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

A case report of opposite sex twin pairs in which one had female to male gender dysphoria: the role of prenatal exposure to sex hormones in the etiology of gender dysphoria

The etiology of gender dysphoria (GD) is not fully known. In recent years, there are studies suggesting that the development of GD is related to some biological mechanisms. The hypothesis conveying that there is a biological background in the development of GD emphasize the importance of exposure to sex hormones in prenatal period. According to this hypothesis, while prenatal exposure to sex hormones causes development of male identity, nonexposure results with female identity. This hypothesis is supported with determination of the relationship between prenatal exposure to testosterone and masculine behaviors, in complete androgen insensitivity syndrome mostly development of female identity, and presence of near values of 2nd and 4th finger ratio in individuals with GD and the individuals with the sex they want to pass. In this article, one of the twins is male and the other one is female-to-male GD case was discussed in terms of the roles of prenatal exposure to sex hormones in the etiology of GD

Total Tau and Phosphorylated Tau Protein Serum Levels in Patients with Schizophrenia Compared with Controls

Tau protein is located in the axons of neurons and in Alzheimer Disease, is abnormally phosphorylated and aggregates into paired helical filaments (neurofibrillary tangles) reflecting the degree of neurofibrillary pathology and neurodegeneration. Although tau and phosphorylated tau (p-Tau) pathology is a hallmark for dementia, few studies were performed in patients of schizophrenia. This preliminary serum study was designed to compare serum total tau and p-Tau levels of schizophrenia patients with healthy controls. The study was included 42 patients diagnosed with schizophrenia and 42 healthy control subjects. Sociodemographic form was applied to both groups and PANSS was applied to patient group. Serum total tau and p-Tau levels were measured by ELISA method. Total tau and p-Tau levels of patients were significantly lower than healthy controls. There was a positive correlation between amount of past electroconvulsive therapies and total tau level. However total tau and p-Tau levels were positively correlated. Our study results showed that serum total tau and p-Tau levels of patients with schizophrenia were significantly lower than healthy controls

Efficacy of accelerated vaccination against Hbv to achieve antibody formation in multiple sclerosis patients receiving anti-Cd20 therapy

Aim: Ocrelizumab is a monoclonal antibody that has been approved for use in both relapsing–remitting multiple sclerosis (RRMS) and primary progressive multiple sclerosis (PPMS). Since ocrelizumab acts on B cells, it also affects humoral immunity, thus reducing the vaccine response. In this study, we aimed to elucidate the relationship between the antibody response following rapid vaccination against hepatitis B virus (HBV) in multiple sclerosis (MS) patients receiving ocrelizumab treatment, and the time of vaccination. Materials and Methods: A total of 220 MS patients were included in this retrospective analysis. The patients' baseline HBV serostatuses (HbsAg, Anti-HbsAb, Anti-HbcAb), previous drug history for MS, whether they were vaccinated against HBV in the past, vaccination status before or after ocrelizumab treatment, and protective antibody titers according to vaccination times, occult HBV incidence and initiation of antiviral treatment were evaluated. Results: Forty-nine percent of MS patients using ocrelizumab were not vaccinated against HBV. The patients were divided into three groups according to their vaccination status as: individuals vaccinated in the past (7.3%, n = 16), vaccinated before treatment (4.5%, n = 10), and vaccinated after treatment (22.3%, n = 49). The antibody titers of the patients in the 6th month after ocrelizumab treatment were measured as 78 mIU/ml, 193 mIU/ml, and 0, respectively. The number of patients with occult HBV infection was 38. Conclusion: In patients with a suspected diagnosis of MS, HBV serostatus should be evaluated at the beginning and if necessary, patients should be vaccinated in the early period. Vaccinating patients at least 1 month before initiating multiple sclerosis treatment is more effective in terms of protective antibody formation

Alterations in Body Uneasiness, Eating Attitudes, and Psychopathology Before and After Cross-Sex Hormonal Treatment in Patients with Female-to-Male Gender Dysphoria

Body dissatisfaction plays an important role in the development of psychiatric problems such as eating disorders as well as gender dysphoria (GD). Cross-sex hormonal treatment (CHT) alleviates the dissatisfaction by making various changes in the body. We examined the alteration of body uneasiness, eating attitudes and behaviors, and psychological symptoms longitudinally in Turkish participants with female-to-male gender dysphoria (FtM GD) after CHT. Thirty-seven participants with FtM GD and 40 female controls were asked to complete the Body Uneasiness Test to explore different areas of body-related psychopathology, the Eating Attitudes Test to assess eating disturbances, and the Symptom Checklist-90 Revised to measure psychological state, both before CHT and after 6months of CHT administration. The baseline mean body weight, BMI scores, body uneasiness scores, and general psychopathological symptoms of participants with FtM GD were significantly higher than female controls, whereas baseline eating attitudes and behaviors were not significantly different. Over time, FtM GD participants' mean body weight and BMI scores increased, body uneasiness and general psychopathological symptoms decreased, and eating attitudes and behaviors had not changed at 24th weeks following CHT administration compared to baseline. CHT may have a positive impact on body uneasiness and general psychopathological symptoms in participants with FtM GD. However, CHT does not have an impact on eating attitudes and behaviors

Differences Between General Neurologists And Multiple Sclerosis Specialists In The Management Of Multiple Sclerosis Patients: A National Survey

Introduction: The management of multiple sclerosis (MS) has become more complicated after the introduction of new diagnostic and treatment options. Despite the abundance of guidelines, the experience of physicians still plays a major role in the management of patients. This study aimed to define differences in behavior patterns between general neurologists (GNs) and MS specialists (MSSs). Methods: We conducted a survey of 36 questions to 318 neurologists, including 33 MSSs. The survey covered topics including laboratory investigations, pregnancy, and treatment. Results: Our study found many differences between GNs and MSSs in terms of management, the most important being treatment initiation and switching. GNs had a tendency to initiate treatment later than MSSs however, they tended to switch treatment faster. Our study also showed that GNs ordered magnetic resonance imaging (MRI) more frequently than MSSs, even if patients were clinically stable. Moreover, although GNs more frequently relied on MRI, they did not consider brain atrophy as an important measure in the follow-up of their patients. Furthermore, GNs considered replacement therapy less often than MSSs, even in patients with vitamin D deficiency. Discussion: Our study revealed important discrepancies between the management patterns of GNs and MSSs in MS patients. These findings suggest the need for a national education program for GNs on MSSs.Wo

A 12-Month, Open Label, Multicenter Pilot Study Evaluating Fingolimod Treatment In Terms Of Patient Satisfaction In Relapsing Remitting Multiple Sclerosis Patients Fine Trial

Introduction: To assess satisfaction and quality of life in patients with relapsing-remitting multiple sclerosis (RRMS) who were receiving fingolimod (0.5 mg/day) for 12 months as a second-line treatment after switching from injectable agents. Methods: Patients aged 18-65 years with RRMS who fulfilled the eligibility criteria were enrolled from 16 centers throughout Turkey. Treatment Satisfaction Questionnaire for Medication and 36-item Short-Form Health Survey were completed at baseline and four visits to assess patient satisfaction and quality of life. Results: Forty-two patients (62% male; mean age: 35.7 +/- 9.4 years) were eligible for inclusion. Patient satisfaction scores at the end of the study 44.7 +/- 9.9) were significantly higher than those at baseline [32.0 +/- 9.9; (p<0.001)]. The only significant increase in the quality of life survey was in the emotional aspect (p=0.019). There were 124 adverse events and none of the five serious adverse events noted was considered drugrelated. Conclusion: Large-scale comparative studies performed with disease specific quality of life instruments will allow more information on this issue.Wo
