RESUMO
PURPOSE OF REVIEW: Cytomegalovirus (CMV) is the most common viral cause of congenital infection, occurring in approximately 1-2% of live births worldwide. Given our increasing knowledge of risk, advances in the identification of maternal infection, and the extremely limited options for the treatment of fetal infection, the prevention is a promising direction for research efforts. Recently, there have been several exciting studies assessing different ways of preventing congenital infection in the fetus and one in particular has focused on the use of valaciclovir. RECENT FINDINGS: A recent study reported a 71% reduction in vertical transmission of CMV with the use of oral valaciclovir following maternal primary CMV infection early in pregnancy. The clinical impact of this study could be enormous and it has particular implications for considerations around maternal serological screening in the first trimester of pregnancy. Further research assessing behaviour modifications during early pregnancy could also provide evidence for an effective primary prevention technique. SUMMARY: Prevention of congenital CMV infection, whether primary, secondary or tertiary, is possible, however, there are barriers to its utilisation in a clinical setting. The main limitation is the requirement for early, effective and large-scale serological screening of mothers to detect asymptomatic primary infection.

OBJECTIVES: To map current practice regarding discussions around resuscitation across England and Scotland in patients with cancer admitted acutely to hospital and to demonstrate the value of medical students in rapidly collecting national audit data. METHODS: Collaborators from the Macmillan medical student network collected data from 251 patient encounters across eight hospitals in England and Scotland. Data were collected to identify whether discussion regarding resuscitation was documented as having taken place during inpatient admission to acute oncology. As an audit standard, it was expected that all patients should be invited to discuss resuscitation within 24 hr of admission. RESULTS: Resuscitation discussions were had in 43.1% of admissions and of these 64.0% were within 24 hr; 27.6% of all admissions. 6.5% of patients had a "do not attempt resuscitation" order prior to admission with a difference noted between patients receiving palliative and curative treatment (8.5% and 0.39%, respectively, p < .05). Discussions regarding escalation of care took place in only 29.3% of admissions. CONCLUSIONS: These data highlight deficiencies in the number of discussions regarding resuscitation that are being conducted with cancer patients that become acutely unwell. It also demonstrates the value of medical student collaboration in rapidly collecting national audit data.

OBJECTIVES: To estimate COVID-19 infections and deaths in healthcare workers (HCWs) from a global perspective during the early phases of the pandemic. DESIGN: Systematic review. METHODS: Two parallel searches of academic bibliographic databases and grey literature were undertaken until 8 May 2020. Governments were also contacted for further information where possible. There were no restrictions on language, information sources used, publication status and types of sources of evidence. The AACODS checklist or the National Institutes of Health study quality assessment tools were used to appraise each source of evidence. OUTCOME MEASURES: Publication characteristics, country-specific data points, COVID-19-specific data, demographics of affected HCWs and public health measures employed. RESULTS: A total of 152 888 infections and 1413 deaths were reported. Infections were mainly in women (71.6%, n=14 058) and nurses (38.6%, n=10 706), but deaths were mainly in men (70.8%, n=550) and doctors (51.4%, n=525). Limited data suggested that general practitioners and mental health nurses were the highest risk specialities for deaths. There were 37.2 deaths reported per 100 infections for HCWs aged over 70 years. Europe had the highest absolute numbers of reported infections (119 628) and deaths (712), but the Eastern Mediterranean region had the highest number of reported deaths per 100 infections (5.7). CONCLUSIONS: COVID-19 infections and deaths among HCWs follow that of the general population around the world. The reasons for gender and specialty differences require further exploration, as do the low rates reported in Africa and India. Although physicians working in certain specialities may be considered high risk due to exposure to oronasal secretions, the risk to other specialities must not be underestimated. Elderly HCWs may require assigning to less risky settings such as telemedicine or administrative positions. Our pragmatic approach provides general trends, and highlights the need for universal guidelines for testing and reporting of infections in HCWs.

A best evidence topic was written according to a structured protocol. The question addressed was: in patients with inoperable early-stage primary lung cancer does microwave ablation (MWA) or stereotactic ablative body radiotherapy (SBRT) achieve improved outcomes in terms of local control, recurrence, survival and complications? Altogether, more than 550 papers were found using the reported search, of which 12 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. No single study directly compared the effects of MWA with SBRT. However, the best available evidence for MWA (7 studies) was compared to that for SBRT (5 studies). The range of 3-year survival reported for MWA was 29.2-84.7%, compared with 42.7-63.5% for SBRT. The range of median survival was 35-60 months for MWA and 32.6-48 months for SBRT. This suggests similar outcomes between these two 2 techniques. Different side-effect profiles were observed between techniques with MWA associated with pneumothorax and fever and SBRT most commonly causing radiation pneumonitis and rib fractures. The evidence base for MWA is less than that for SBRT and is heterogenous in terms of participants and technical design. However, within these limitations, we conclude that MWA appears comparable with SBRT in terms of local control and survival rates.

INTRODUCTION: Abnormally invasive placenta (AIP) is a rare pregnancy complication often resulting in postpartum haemorrhage (PPH) and emergency peripartum hysterectomy (EPH). The risk of developing post traumatic stress disorder (PTSD) following unexpectedly traumatic childbirth is known however there is no evidence regarding PTSD in AIP. This pilot study assesses the risk of PTSD for women with AIP compared to women having an uncomplicated caesarean delivery (CD) or unexpected PPH or EPH. METHODS: Retrospective case-controlled questionnaire study in a UK Tertiary obstetric unit. Women with AIP (Group-1) were matched by delivery date to control groups: Group-2, women with an uncomplicated CD; Group-3 women referred to a specialist clinic for suspected AIP, but had a normal placenta and uncomplicated CD; Group-4, women who had an unexpected EPH and/or severe (>3000â¯mls) PPH. 218 women were sent a validated PTSD screening questionnaire (Impacts of Events Scale-Revised [IES-R]). RESULTS: Likelihood of PTSD was recorded for 69 women who responded, revealing significantly higher PTSD scores for women with AIP compared to uncomplicated CD (Pâ¯=â¯0.001). No significant difference was seen between AIP and EPH/PPH (Pâ¯=â¯0.89). The number of women with scores high enough to indicate probable PTSD was significantly greater with AIP than uncomplicated CD group (Pâ¯=â¯0.045). DISCUSSION: This study demonstrates that women antenatally diagnosed with AIP and anticipating a potentially traumatic delivery, are at significantly increased risk of developing PTSD. Improved awareness of the negative psychological impact of AIP may increase the number of women being identified and treated, thereby improving their quality of life.
