Acute Flaccid Paralyses Surveillance (AFPS) monitors the emergence of polioviruses and can track Non-Polio Enteroviruses (NPEVs). We report AFPS activity in the Lombardy region (Northern Italy) from 2016 to 2018.

Fecal and respiratory samples were collected from children <15 years who met the WHO definition of an AFP case, analyzed by virus isolation in cell cultures (RD/L20B) and by a one-step real-time RT-PCR assay specific for the 5'-noncoding-region of NPEV. Fisogatinib clinical trial NPEV-positive specimens were further analyzed by sequencing a fragment of the VP1 gene.

36 AFP cases (89 stool and 32 respiratory samples) were reported with an incidence of 1.1/100'000, 0.9/100'000, 0.6/100'000 children <15 years in 2016, 2017, 2018, respectively. Poliovirus was not identified, whereas NPEVs were detected in 19.4% (7/36) of AFP cases. The presence of one Echovirus-25 (2016), two EV- and D68 (2016 and 2018), one EV-A71 (2016), and one Echovirus-30 (2016) sharing high nucleotide identity with NPEVs detected in Europe was identified.

The absence of polio was confirmed. The unpredicted detection of emerging EV-D68, EV-A71, and E-30 sharing high sequence nucleotide similarity with viruses involved in the latest outbreaks, provided valuable and up-to-date information, emphasizing the importance of monitoring NPEVs through AFPS.

The COVID-19 pandemic in Malawi emerged amidst widespread anti-government demonstrations and subsequent mass gatherings. This paper describes the incidence and factors associated with the spread of the COVID-19 pandemic in Malawi.

This was a retrospective study of public data analysing geopolitical and immigration activities that occurred between 02 April and 08 September 2020. The Chi-square test of independence was used to tabulate sex and age-related fatality ratios among deaths due to COVID-19-related complications.

The drivers for COVID-19 spread were mass gatherings secondary to the country's political landscape and repatriation of citizens from high-risk areas coupled with minimum use of public health interventions. The prevalence was higher in people aged 50-59 years, males and in urban areas. Men had an increased risk of COVID-19-related deaths (Case Fatality Ratio 1.58 (95% CI 1.11-2.22) compared with women. Furthermore, men and women aged ≥40 years were 16.1 times and 7.1 times more likely tod urban areas should be prioritised for COVID-19 prevention strategies.

Addressing the needs of ethnic minorities will be key to finding undiagnosed individuals living with hepatitis B (HBV), hepatitis C (HCV), or human immunodeficiency virus (HIV). To inform screening initiatives in British Columbia (BC), Canada, the factors associated with HBV and/or HCV and/or HIV infection among different ethnic groups within a large population-based cohort were assessed.

Persons diagnosed with HBV, HCV, or HIV in BC between 1990 and 2015 were grouped as East Asian, South Asian, Other Visible Minority (African, Central Asian, Latin American, Pacific Islander, West Asian, unknown ethnicity), and Not a Visible Minority, using a validated name-recognition software. Factors associated with infection within each ethnic group were assessed with multivariable multinomial logistic regression models.

Participants included 202 521 East Asians, 126 070 South Asians, 65 210 Other Visible Minorities, and 1 291 561 people who were Not a Visible Minority, 14.4%, 3.3%, 4.5%, and 6.3% of whom had HBV anion screening among different ethnic groups.

Observational and experimental studies suggest that the use of antibiotics close to administration of immune checkpoint inhibitors (ICI) can have a negative effect on tumour response and patient survival, due to microbiome dysbiosis and the resultant suppression of host immune response against neoplastic cells.

A systematic search of PUBMED and EMBASE was undertaken for studies published between 1 January 2017 and 1 June 2020, evaluating the association between the use of antibiotics and clinical outcomes in patients with cancer treated with ICIs. A meta-analysis of the association between the use of antibiotics and clinical outcomes was also performed.

Forty-eight studies met the inclusion criteria (12,794 patients). Use of antibiotics was associated with shorter overall survival [hazard ratio (HR) 1.88, 95% confidence interval (CI) 1.59-2.22; adjusted HR 1.87, 95% CI 1.55-2.25] and progression-free survival (HR 1.52, 95% CI 1.36-1.70; adjusted HR 1.93, 95% CI 1.59-2.36), decreased response rate [odds ratio (OR) 0.54, 95% CI 0.34-0.86] and more disease progression (OR 2.00, 95% CI 1.27-3.14). The negative association between the use of antibiotics and progression-free survival was stronger in patients with renal cell carcinoma or melanoma compared with lung cancer. Only antibiotic administration >1 month prior to ICI initiation was associated with increased disease progression. Heterogeneity was substantial for all outcomes.

Recent use of antibiotics in patients with cancer treated with ICIs was associated with worse clinical outcomes. Such patients may benefit from dedicated antimicrobial stewardship programmes.

To describe the clinical characteristics and outcomes of hospitalized coronavirus disease 2019 (COVID-19) patients in a middle east respiratory syndrome coronavirus (MERS-CoV) referral hospital during the peak months of the pandemic.

A single-center case series of hospitalized individuals with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in King Saud University Medical City (KSUMC), an academic tertiary care hospital in Riyadh, Saudi Arabia. link2 Clinical and biochemical markers were documented. Risks for ventilatory support, intensive care unit (ICU) admission and death are presented.

Out of 12,688 individuals tested for SARS-CoV-2 by real time reverse transcriptase polymerase reaction (RT-PCR) from June 1 to August 31, 2020, 2,683 (21%) were positive for COVID-19. Of the latter, 605 (22%) patients required hospitalization with a median age of 55, 368 (61%) were male. The most common comorbidities were hypertension (43%) and diabetes (42%). Most patients presented with fever (66%), dyspnea (65%), cough (61%), elevated IL-6 (93.5%), D-dimer (90.1%), CRP (86.1%), and lymphopenia (41.7%). No MERS-CoV co-infection was detected. Overall, 91 patients (15%) died; risk factors associated with mortality were an age of 65 years or older OR 2.29 [95%CI 1.43-3.67], presence of two or more comorbidities OR 3.17 [95%CI 2.00-5.02], symptoms duration of seven days or less OR 3.189 [95%CI (1.64 - 6.19]) lymphopenia OR 3.388 [95%CI 2.10-5.44], high CRP OR 2.85 [95%CI 1.1-7.32], high AST OR 2.95 [95%CI 1.77-4.90], high creatinine OR 3.71 [95%CI 2.30-5.99], and high troponin-I OR 2.84 [95%CI 1.33-6.05].

There is a significant increase in severe cases of COVID-19. Mortality was associated with older age, shorter symptom duration, high CRP, low lymphocyte count, and end-organ damage.

Ready-to-eat (RTE) food sold in Quetta, Pakistan was assessed for microbial contamination.

Equal numbers of samples were collected from four categories of RTE food - burgers, shawarma, pizza and sandwiches - from January 2018 to December 2018. Microbial contamination of individual food samples was assessed by quantifying the total aerobic count obtained from plating samples on bacterial growth medium. Salmonella spp. serovars were identified using polymerase chain reaction.

Approximately 38% (121/320) of RTE food samples were not fit for human consumption. The most contaminated type of RTE food was shawarma (49%). Microbial contamination of food samples was higher in summer compared with the other seasons. Approximately 40% (49/121) of food samples that were not fit for human consumption were contamined with Salmonella spp. Salmonella enteritidis (69%) and Salmonella typhimurium (31%) were the only serovars among the samples testing positive for Salmonella spp. Of the 49 samples with high microbial counreduce the healthcare burden.

A colistin loading dose is required to achieve adequate drug exposure for the treatment of multidrug-resistant Gram-negative bacteria. However, data on acute kidney injury (AKI) rates associated with this approach in children have been unavailable. The aim of this study was to examine AKI rates in children who were prescribed a colistin loading dose.

A retrospective study was conducted in patients aged 1 month to 18 years who had received intravenous colistin for ≥48 h. Loading dose (LD) was defined as colistin methanesulfonate at 4-5 mg of colistin base activity/kg/dose. AKI was defined according to KDIGO serum creatinine (SCr) criteria - SCr ≥ 1.5 times the baseline, measured 3-7 days after colistin initiation. Augmented renal clearance (ARC) was defined as an estimated glomerular filtration rate (eGFR) >150 mL/min/1.73 m

. The rates of AKI were compared between children receiving or not receiving an LD, and between different eGFR groups.

In total, 181 children were enrolled. The mean age was 4.3 years (95% confidence interval [CI], 3.6-4.9 years). Ninety-five of the subjects (52.5%) were male. There were 157 children with a baseline eGFR of ≥ 80 mL/min/1.73 m

. The overall AKI rate within the first week in this group was 20.4% (95% CI, 14.4-27.6%) LD, 16.1% vs no LD, 23.2% (p = 0.29). Subgroup analysis, excluding patients with ARC, showed a lower AKI rate of 12.8% (95% CI, 6.8-21.3%) LD, 9.7% vs no LD, 14.3% (p = 0.53).

AKI rate was not different among children who received an intravenous colistin loading dose. This approach should be implemented to ensure the necessary drug exposure required for good treatment outcomes.

To determine patterns of mask wearing and other infection prevention behaviours, over two time periods of the COVID-19 pandemic, in cities where mask wearing was not a cultural norm.

A cross-sectional survey of masks and other preventive behaviours in adults aged ≥18 years was conducted in five cities Sydney and Melbourne, Australia; London, UK; and Phoenix and New York, USA. link3 Data were analysed according to the epidemiology of COVID-19, mask mandates and a range of predictors of mask wearing.

The most common measures used were avoiding public areas (80.4%), hand hygiene (76.4%), wearing masks (71.8%) and distancing (67.6%). Over 40% of people avoided medical facilities. These measures decreased from March-July 2020. Pandemic fatigue was associated with younger age, low perceived severity of COVID-19 and declining COVID-19 prevalence. Predictors of mask wearing were location (US, UK), mandates, age <50 years, education, having symptoms and knowing someone with COVID-19. Negative experiences with mask wearing and low perceived severity of COVID-19 reduced mask wearing.
