Clonal analysis of Staphylococcus aureus strains isolated in obstetric-gynaecological hospital

Epidemiological studies were carried out on 135 isolates of Staphylococcus aureus strains originating from medical staff, patients, and hospital environment. Restriction fragment length polymorphism (RFLP) analysis revealed genetic diversity of S. aureus isolates. Some clones were transmitted among nurses, doctors and patients. Our studies also demonstrate contamination of the hospital environment with S. aureus strains and there is a possibility that the patients acquire staphylococci from the environment. Moreover, we found that many medical staff workers were colonized with S. aureus and the transmission of these strains to patients is possible.

Re-detectable positive SARS-CoV-2 RNA tests in patients who recovered from COVID-19 with intestinal infection

Dear Editor,Severe acute respiratory syndrome coronavirus 2(SARSCoV-2),a novel coronavirus that causes Coronavirus Disease 2019(COVID-19)(Yang and Wang,2020),has spread to more than 200 countries and infected more than 9,000,000 people as of Jun 2020.Tens of thousands of patients with COVID-19 have recovered and been discharged from hospital.However,there are reports of recovered patients who subsequently tested positive for SARSCoV-2 after discharge(re-detectable positive,RP)(An et al.,2020;Lan et al.,2020),and this has led to increasing focus on the mechanism(s)underlying RP.     

A five‐step risk management process for geriatric dental practice during SARS‐CoV‐2 pandemic

Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is an RNA virus that causes coronavirus infection (COVID‐19). COVID‐19 is a highly contagious disease transmitted through respiratory droplets, saliva and other contact routes. Within 10 months of its outbreak, SARS‐CoV‐2 has infected more than 23 million people around the world. Evidence suggests that older adults are the most vulnerable to infection and have an increased risk of mortality. Reduced immunity and underlying medical conditions make them risk‐prone and vulnerable to critical care. Older adults affected with the SARS‐CoV‐2 virus present with distinct clinical manifestations necessitating specific treatment needs and management protocols. While it is crucial to prevent the spread of novel coronavirus (2019‐nCoV), the role of oral healthcare workers in addressing the specific needs of ageing adult patients by adopting specific guidelines and appropriate infection control protocols is timely. This paper aims to develop specific guidelines and protocols for the dental management of geriatric patients during the COVID‐19 pandemic.     

Hepatitis B virus infection in medical and health care personnel.

Analysis of 51 cases of hepatitis B virus infection in health care workers admitted as patients to the liver unit over seven years showed three healthy carriers of hepatitis B virus, seven cases of fulminant hepatic persistent hepatitis, 17 cases of chronic active hepatitis (of whom 11 had cirrhosis), and five cases of hepatocellular carcinoma. To date 11 of these patients have died. Only 15 of the 51 patients had a history of direct occupational exposure and only three patients could recall specific inoculation injuries. In contrast, the source of infection was apparent in 32 of 50 consecutive cases of fulminant hepatic failure or acute hepatitis B in nonmedical staff. Since specific inoculation injuries are not the usual mode of infection ion medical staff and since only a few of the patients who are hepatitis B virus carriers will be detected by selective screening of "high-risk" patients, the overall risk of infection can be reduced only by stricter precautions in the handling of any patient''s blood and by the use of hepatitis B virus vaccines for medical staff at high risk.     

Mouse-adapted SARS-CoV-2 protects animals from lethal SARS-CoV challenge

The emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has resulted in a pandemic causing significant damage to public health and the economy. Efforts to understand the mechanisms of Coronavirus Disease 2019 (COVID-19) have been hampered by the lack of robust mouse models. To overcome this barrier, we used a reverse genetic system to generate a mouse-adapted strain of SARS-CoV-2. Incorporating key mutations found in SARS-CoV-2 variants, this model recapitulates critical elements of human infection including viral replication in the lung, immune cell infiltration, and significant in vivo disease. Importantly, mouse adaptation of SARS-CoV-2 does not impair replication in human airway cells and maintains antigenicity similar to human SARS-CoV-2 strains. Coupled with the incorporation of mutations found in variants of concern, CMA3p20 offers several advantages over other mouse-adapted SARS-CoV-2 strains. Using this model, we demonstrate that SARS-CoV-2–infected mice are protected from lethal challenge with the original Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), suggesting immunity from heterologous Coronavirus (CoV) strains. Together, the results highlight the use of this mouse model for further study of SARS-CoV-2 infection and disease.

Studying cross-protection from different coronaviruses is important to inform the research for a universal vaccine. This study uses a mouse-adapted SARS-CoV-2 strain to show that it confers protection from SARS-CoV challenge, suggesting possible immunity from heterologous challenge following natural infection.     

Review of cases of nosocomial Lassa fever in Nigeria: the high price of poor medical practice.

OBJECTIVE--To investigate two hospital outbreaks of Lassa fever in southern central Nigeria. SETTING--Hospitals and clinics in urban and rural areas of Imo State, Nigeria. DESIGN--Medical records were reviewed in hospitals and clinics in both areas. Patients with presumed and laboratory confirmed Lassa fever were identified and contracts traced. Hospital staff, patients, and local residents were questioned, records were carefully reviewed, and serum samples were taken. Serum samples were assayed for antibody specific to Lassa virus, and isolates of Lassa virus were obtained. RESULTS--Among 34 patients with Lassa fever, including 20 patients, six nurses, two surgeons, one physician, and the son of a patient, there were 22 deaths (65% fatality rate). Eleven cases were laboratory confirmed, five by isolation of virus. Most patients had been exposed in hospitals (attack rate in patients in one hospital 55%). Both outbreak hospitals were inadequately equipped and staffed, with poor medical practice. Compelling, indirect evidence revealed that parenteral drug rounds with sharing of syringes, conducted by minimally educated and supervised staff, fuelled the epidemic among patients. Staff were subsequently infected during emergency surgery and while caring for nosocomially infected patients. CONCLUSION--This outbreak illustrates the high price exacted by the practice of modern medicine, particularly use of parenteral injections and surgery, without due attention to good medical practice. High priority must be given to education of medical staff in developing countries and to guidelines for safe operation of clinics and hospitals. Failure to do so will have far reaching, costly, and ultimately devastating consequences.     

Erysipeloid as an occupational disease of workers in shoe enterprises

An outbreak of erysipeloid among the workers of a shoe factory is described. The spread of infection occurred due to contact with infected raw materials, which was confirmed by the isolation of Erysipelotrix rhusiopathiae from washings made from chrome and Russia leather supplied by different tanneries, as well as from casein glue. The raw materials could be additionally infected by rodents, in particular by common voles; the above-mentioned infective agent had been repeatedly isolated from these animals on the territory of this region. Leather was also infected in the process of soaking: the infective agent was isolated from the water of soaking baths. For the first time the routes of the spread of erysipeloid infection among shoe factory workers were bacteriologically confirmed. The recommended complex of sanitary, medical and antiepidemic measures led to the liquidation of the outbreak and thus proved to be effective. The authors draw the attention of epidemiologists, sanitary inspectors, occupational pathologists and heads of medical centers at shoe factories to the necessity of preventing the spread of occupational erysipeloid infection among the workers, as well as to the necessity for dermatologists, surgeons and infectionists, most frequently dealing with erysipeloid patients, to be correctly oriented in respect to this infection.     

Genetic screening and genetic counseling: knowledge, attitudes, and practices in two groups of family planning professionals.

67 obstetrical and gynecological physicians and 102 professional staff members of family planning clinics (FPCs) in the Pittsburgh, Pennsylvania, area returned questionnaires relating to knowledge of basic genetic principles and attitudes towards genetic screening and genetic counseling. The best understood genetic risk was Down's syndrome in children born to mothers over 40 years of age. Nearly 90% of physicians and 85% of FPC staff knew this but only 12% of physicians and 30% of FPC staff knew it is caused by chromosomal aberration. Next best understood defect is sickle cell anemia. In overall knowledge the physicians had a mean score of 4.45 of 7 genetic questions, FPC staff, 3.32. However, FPC workers who had received in-service genetic training scored 4.42 (p less than .001). Knowledge of the 2 genetic clinics in the area and acceptance of the principles of genetic screening were associated with the individual's acceptance of sterilization as a method of birth control and acceptance of abortion if the fetus had significant risk of being born deformed. Both of these associations were at the significant level for both physicians and FPC workers. Both physicians and FPC workers who have themselves had genetic counseling or who have family members who have had such counseling show higher acceptance levels. An association was also found between acceptance and genetic educational background. About 92% of respondents who had read articles or textbooks pertaining to genetics during the preceding year approved of including genetic information as part of maternal and child health projects compared with 82% of those who had not (p less than .02). Among the physicians 36% felt it should be required, 34% voluntary, and 30% did not know; for FPC workers, 59, 27, and 14%, respectively. Protestants and Jews tended to favor required premarital screening while Catholics tended to oppose it (p less than .007). It is disconcerting that over 50% of the physicians did not know the recurrence risk of PKU and over 20% did not know the gene is the basic unit of inheritance. While it is true that over 1/2 completed basic professional education more than 20 years ago when genetics was not part of the medical school curriculums this basic knowledge needs to have been acquired during continuing medical education. In this study more than 1/3 of the FPC staff indicated they had been asked to provide genetic counseling or had referred clients. This points up the importance of such workers in a comprehensive genetic counseling service.     

Transmission of community- and hospital-acquired SARS-CoV-2 in hospital settings in the UK: A cohort study

BackgroundNosocomial spread of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been widely reported, but the transmission pathways among patients and healthcare workers (HCWs) are unclear. Identifying the risk factors and drivers for these nosocomial transmissions is critical for infection prevention and control interventions. The main aim of our study was to quantify the relative importance of different transmission pathways of SARS-CoV-2 in the hospital setting.Methods and findingsThis is an observational cohort study using data from 4 teaching hospitals in Oxfordshire, United Kingdom, from January to October 2020. Associations between infectious SARS-CoV-2 individuals and infection risk were quantified using logistic, generalised additive and linear mixed models. Cases were classified as community- or hospital-acquired using likely incubation periods of 3 to 7 days. Of 66,184 patients who were hospitalised during the study period, 920 had a positive SARS-CoV-2 PCR test within the same period (1.4%). The mean age was 67.9 (±20.7) years, 49.2% were females, and 68.5% were from the white ethnic group. Out of these, 571 patients had their first positive PCR tests while hospitalised (62.1%), and 97 of these occurred at least 7 days after admission (10.5%). Among the 5,596 HCWs, 615 (11.0%) tested positive during the study period using PCR or serological tests. The mean age was 39.5 (±11.1) years, 78.9% were females, and 49.8% were nurses. For susceptible patients, 1 day in the same ward with another patient with hospital-acquired SARS-CoV-2 was associated with an additional 7.5 infections per 1,000 susceptible patients (95% credible interval (CrI) 5.5 to 9.5/1,000 susceptible patients/day) per day. Exposure to an infectious patient with community-acquired Coronavirus Disease 2019 (COVID-19) or to an infectious HCW was associated with substantially lower infection risks (2.0/1,000 susceptible patients/day, 95% CrI 1.6 to 2.2). As for HCW infections, exposure to an infectious patient with hospital-acquired SARS-CoV-2 or to an infectious HCW were both associated with an additional 0.8 infection per 1,000 susceptible HCWs per day (95% CrI 0.3 to 1.6 and 0.6 to 1.0, respectively). Exposure to an infectious patient with community-acquired SARS-CoV-2 was associated with less than half this risk (0.2/1,000 susceptible HCWs/day, 95% CrI 0.2 to 0.2). These assumptions were tested in sensitivity analysis, which showed broadly similar results. The main limitations were that the symptom onset dates and HCW absence days were not available.ConclusionsIn this study, we observed that exposure to patients with hospital-acquired SARS-CoV-2 is associated with a substantial infection risk to both HCWs and other hospitalised patients. Infection control measures to limit nosocomial transmission must be optimised to protect both staff and patients from SARS-CoV-2 infection.

In a cohort study, Mo Yin and colleagues investigate transmission of community- and hospital-acquired SARS-CoV-2 in hospital settings in the UK.

Infection of SARS-CoV-2 causes severe pathological changes in mouse testis

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has affected more than 600 million people worldwide. Several organs including lung, intestine, and brain are infected by SARS-CoV-2. It has been reported that SARS-CoV-2 receptor angiotensin-converting enzyme-2 (ACE2) is expressed in human testis. However, whether testis is also affected by SARS-CoV-2 is still unclear. In this study, we generate a human ACE2 (hACE2) transgenic mouse model in which the expression of hACE2 gene is regulated by hACE2 promoter. Sertoli and Leydig cells from hACE2 transgenic mice can be infected by SARS-CoV-2 pseudovirus in vitro, and severe pathological changes are observed after injecting the SARS-CoV-2 pseudovirus into the seminiferous tubules. Further studies reveal that Sertoli and Leydig cells from hACE2 transgenic mice are also infected by authentic SARS-CoV-2 virus in vitro. After testis interstitium injection, authentic SARS-CoV-2 viruses are first disseminated to the interstitial cells, and then detected inside the seminiferous tubules which in turn cause germ cell loss and disruption of seminiferous tubules. Our study demonstrates that testis is most likely a target of SARS-CoV-2 virus. Attention should be paid to the reproductive function in SARS-CoV-2 patients.

Community Nurses' View of General Practice Attachment

An analysis of 98 health visitors and district nurses attached and non-attached to general practitioners in three local authority areas showed that most of them were aged over 40 and that many had entered domiciliary work because of the convenient hours or because of its intangible attractions. Adequate preparation for attachment was considered important, particularly a clear definition of the roles of the attached staff and their relationships to other workers in the practice.Attached staff were found to be much more satisfied with the information given by the general practitioner about their patients than were unattached staff, and the former usually had access to the patients'' medical records. The principal advantages of attachment were listed as access to family history; improved co-ordination within the practice and co-operation with the social services; favourable patient response; and increased mileage and work-load; the impossibility of crossing local authority boundaries; and having to deal with families registered with more than one doctor.     

Incidence of tuberculosis,hepatitis, brucellosis,and shigellosis in British medical laboratory workers.

A retrospective postal survey of 21 000 medical laboratory workers in England and Wales showed 18 new cases of pulmonary tuberculosis in 1971, a five-times increased risk of acquiring the disease compared with the general population. Technicians were at greatest risk, especially if they worked in morbid anatomy departments. Of the 35 cases of hepatitis, the technicians were again the occupational group most likely to acquire the disease. Microbiology staff were twice as likely to report shigellosis as those in other pathology divisions but only one case of brucellosis was reported in the whole laboratory population. A similar survey carried out in 1973 of 3000 Scottish medical laboratory workers corroborates the results from England and Wales. Medical laboratory workers continue to experience a considerable risk of developing an occupationally acquired infection. Improvements in staff safety and health care seem to be necessary.     

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2): Emergence,history, basic and clinical aspects

In late December 2019, the world woke to a reality of a pandemic of Coronavirus Disease (COVID-19), elicited by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which belongs to a group of β-coronavirus. The potential to cause life-threatening respiratory failure and rapid transmission puts COVID-19 in the list of Public Health Emergency of International Concern (PHEIC). In the last two decades, this is the 3rd deadliest Coronavirus pandemic, following SARS which lasted between 2002 and 2003 and Middle East Respiratory Syndrome (MERS) from 2012 till date. Globally and as of April 23rd 2020, COVID-19 has affected 2,544,792 individuals in over 200 countries, causing 175,694 fatalities. While the SARS-CoV-2 originated in China with 84,302 confirmed cases and 4642 deaths as at the time of writing this review, the rapid transmission of SARS-CoV-2 has resulted in exponential increase in the number of cases outside of China to about 10 times the report case and death in mainland China. SARS-CoV-2 is suspected to be zoonotic in nature as genetic studies have shown sequence similarity to viruses originating from bats. Extreme precautionary measures, such as curfew, shutting of borders and quarantining of individuals suspected to be infected have been instituted with immediate effect; however, due to individuals that are asymptomatic, uncontrolled human-to-human transmission has resulted in exponential infection rate and numerous loss of lives even with this lockdown measures. This review article summarizes the developing situation surrounding the SARS-CoV-2 pandemic with respect to its epidemiology, unique genomic structure, possible origins, transmission, pathogenesis, comparison with other deadly species of Coronaviruses (CoV) and emerging treatment strategies built on informed literature.     

Vaccines and exposed occupations

The use of safe and efficacious vaccines in occupational settings to protect workers from diseases to which they may be exposed is obvious and has been included in the employment law. Healthcare workers are particular exposed. Immunization has two purposes : protect the worker from contracting a disease, but also prevent him from disseminating the disease to weakened patients. It is important not only to take into account existing recommendations for immunization, but also to envisage their extension to teachers and staff of nurseries and primary schools. Routine vaccination against whooping cough, varicella, measles and hepatitis A is particularly warranted in these categories. Recommendations should also extend to medical students who are too often poorly protected and insufficiently warned against potential occupational exposure to pathogens and dissemination to their patients.
