COVID-19 Gender Disparities and Mitigation Recommendations: A Narrative Review

The coronavirus disease 2019 (COVID-19) pandemic has rapidly created widespread impacts on global health and the economy. Data suggest that women are less susceptible to severe illness. However, sex-disaggregated data are incomplete, leaving room for misinterpretation, and focusing only on biologic sex underestimates the gendered impact of the pandemic on women. This narrative review summarizes what is known about gender disparities during the COVID-19 pandemic and the economic, domestic, and health burdens along with overlapping vulnerabilities related to the pandemic. In addition, this review outlines recommended strategies that advocacy groups, community leaders, and policymakers should implement to mitigate the widening gender disparities related to COVID-19.     

Dengue vaccine: WHO position paper,September 2018 – Recommendations

This article presents the World Health Organization’s (WHO) recommendations on the use of dengue vaccine excerpted from the WHO position paper on dengue vaccine – September 2018, published in the Weekly Epidemiological Record [1]. This position paper replaces the July 2016 WHO position paper concerning the first licensed dengue vaccine, CYD-TDV [2]. The position paper presents new evidence that became available in November 2017. A retrospective analysis of data from clinical trials, using a new serological assay classified trial participants according to their dengue serostatus prior to receipt of the first vaccine dose. The analysis revealed an excess risk of severe dengue in seronegative vaccine recipients compared to seronegative non-vaccinated individuals, while confirming long-term protection in seropositive individuals [3]. The paper provides revised guidance on dengue vaccination strategies from a population health perspective.Footnotes to this paper provide a number of core references including references to grading tables that assess the quality of the scientific evidence, and to the evidence-to-recommendation table. In accordance with its mandate to provide guidance to Member States on health policy matters, WHO issues a series of regularly updated position papers on vaccines and combinations of vaccines against diseases that have an international public health impact. These papers are concerned primarily with the use of vaccines in large-scale immunization programmes; they summarize essential background information on diseases and vaccines, and conclude with WHO's current position on the use of vaccines in the global context. Recommendations on the use of dengue vaccine CYD-TDV were discussed by SAGE in April 2018; evidence presented at the meeting can be accessed at: http://www.who.int/immunization/sage/meetings/2018/april/presentations_background_docs/en/     

浅谈口腔医学硕士研究生科研作图能力的培养

科研作图是展示研究数据的主要形式,也是科研素养的重要体现。口腔医学硕士研究生是接触科学研究的第一站,然而目前的研究生教育环节对科研作图能力缺乏系统性培养,许多研究生在科研作图中存在许多不规范的问题,本文针对这一问题进行初步探讨。本文分析比较了常用作图工具Microsoft Excel、Origin和Graphpad Prism的特点;以学校口腔医学硕士的培养过程为参考,分析目前硕士研究生科研作图方面存在的主要问题及应对策略。发现不同作图软件具有不同的风格特点,当前硕士研究生作图存在风格不统一、拼图不规范、图注不规范等问题,应当根据自身需求合理选择作图工具,提升作图能力。科研作图是科研能力的重要方面,应当加强口腔医学硕士研究生作图能力的培养。     

对一宗入境二级放射货包的监测结果分析

汕头卫生检疫局空港处对汕头航空口岸—宗入境二级货包的监测过程及对有关运输工作人员作了放射知识问卷调查。从中发现。运输单位货物存放设施落后。有关工作人员放射卫生知识欠缺，对放射污染可能造成的危害缺乏正确的认识。为此，笔者提出了自己的看法，以期对放射监测工作的进一步完善提供参考。

Mivacurium in infants and children

Mivacurium is the only available short-acting nondepolarizing muscle relaxant in clinical use. It is a bis-quaternary benzylisoquinolinium ester hydrolysed by plasma-cholinesterase into inactive compounds. The ED₅₀ and ED₉₅ in children are about 50 μg·kg^?1 and 90 μg·kg^?1 respectively. In infants, they have a tendency to be lower. A standard intubating dose of 0.25 mg·kg^?1 causes complete neuromuscular depression in 1.5–2 min, recovery to 5% in 6–10 min, and complete recovery in 15–20 min. The recent tendency is to use 0.3 mg·kg^?1 to obtain better intubating conditions with slight prolongation of effect. Since the recovery profile of mivacurium is independent of the dose and duration, it is most suitable for administration by continuous infusion. The infusion requirement in children is 10–16 μg·kg^?1 min^?1, which is about twice that of adults. Cutaneous flushes from histamine release are commonly seen with the larger doses of mivacurium; however, the associated hypotensive effects are minimal and counteracted by the tracheal intubation. The duration of action of mivacurium is prolonged in patients with cholinesterase deficiency. Mivacurium's neuromuscular effects can be satisfactorily antagonized by edrophonium or neostigmine.     

Passive euthanasia in response to attempted suicide: one form of aggressiveness by relatives

A total of 88 interviews were conducted with 40 people attempting suicide who were receiving care in an intensive-care unit, and 129 interviews were carried out with their relatives and friends. The subjects were divided into 3 diagnostic groups: neurosis (n = 14), abuse (n = 19) and psychosis (n = 7). The incidence of relatives' failure to provide care after the suicide attempt--turning-away reactions as well as do not resuscitate orders, a form of passive euthanasia--was investigated. In 8 cases, partners of patients in the abuse and neurosis groups showed turning-away reactions. In 2 cases, relatives of elderly patients in the neurosis group said to the doctor that life-preserving measures should not be taken. Relatives explained their behaviour by saying that they had the best interests of the suicidal individual at heart. In-depth interviews, however, revealed that these reactions were a manifestation of the relatives own psychic conflicts, brought forth by the confrontation with the depressed and suicidal patient. Turning-away reactions and do not resuscitate orders might be interpreted as expressing the relatives' aggressiveness towards the suicidal individual and attempts to escape from a difficult situation. It is important that doctors stand up for the interests of suicidal people, which at times may conflict with relatives' interests, and help the relatives to sort out their problems and wishes with respect to the problem areas of passive euthanasia.

Do discrepancies in interpersonal perception predict relapse?: A comparison of remitted depressed patients and collaterals

In an effort to examine whether disturbed interpersonal relationships are associated with relapse in depression, discrepancies in self-ratings provided by formerly depressed patients and their collateral informants were compared. Thirty-eight remitted depressed patients and their collateral informants were asked to monitor moods, life events, and stress levels on a bimonthly basis for a 1-year period. It was hypothesized that patient/collateral dyads displaying a greater discrepancy in interpersonal perception would have a higher risk of relapse than dyads who showed more agreement in their ratings. Results indicated that while discrepancies in the perceptions of patients' life events were associated with the duration of a relapse once it occurred, discrepancies were generally not related to the emergence of new episodes of depressive disorder. The implications of these findings for models seeking to integrate cognitive and interpersonal models of depression, through the study of environmentally determined and personally appraised adversity, is discussed.This research was supported by grants to the first and third authors from the Canadian Psychiatric Research Foundation and the Laidlaw Foundation.
