Ceftazidime/avibactam (CAZ-AVI), approved in 2015, is an important first-line option for Klebsiella pneumoniae carbapenemase-producing Enterobacterales (KPC-E). Although still uncommon, resistance to CAZ-AVI has emerged and may represent a serious cause of concern.

We performed a systematic literature review of clinical and microbiological features of infections and colonisations by CAZ-AVI-resistant KPC-E, focused on the in vivo emergence of CAZ-AVI resistance in different clinical scenarios.

Twenty-three papers were retrieved accounting for 42 patients and 57 isolates, mostly belonging to K. pneumoniae ST258 harbouring D179Y substitution in the KPC enzyme. The USA, Greece and Italy accounted for 80% of cases. In one-third of isolates resistance was not associated with previous CAZ-AVI exposure. Moreover, 20% of the strains were colistin-resistant and 80% were extended-spectrum β-lactamase (ESBL)-producers. The majority of infected patients had severe underlying diseases (39% cancer, 22% solid-organ tre management of patients with infections caused by CAZ-AVI-resistant strains.
The National Tuberculosis Control Program (NTP) in Pakistan developed, with the Pakistan Paediatric Association, a pediatric scoring chart to aid diagnosis of childhood tuberculosis (TB). Our study compared the diagnostic practice of private healthcare providers in Pakistan with the NTP guidelines.

A cross-sectional study comparing diagnosis of TB in children <15 years by Non-NTP private providers with the NTP's pediatric scoring chart. A generalized linear model was used to determine the difference in adherence by Non-NTP private providers to the NTP guidelines for childhood TB diagnosis by associated factors.

A total of 5193 (79.7% of presumptive childhood TB cases identified in the selected districts during the study) children were diagnosed with TB by Non-NTP private providers. A strong clinical suspicion of TB was present in 17.3%, and chest x-ray was suggestive of TB in 34.3%. The Kappa score between Non-NTP private providers and the NTP guidelines for diagnosing TB was 0.152. Only 47.8% of cases were diagnosed in line with the NTP guidelines. Children <5 years old with a history of TB contact had a higher chance of being diagnosed according to the NTP guidelines.

This study indicates a low adherence of NTP guidelines for diagnosing childhood TB by private providers in Pakistan.

Since 2012, outbreaks of African swine fever (ASF) in domestic pigs have increased outside of South Africa's ASF control zone. This study describes the epidemiological investigation and findings of an ASF outbreak in a small-scale pig unit in Gauteng Province and makes recommendations to prevent future outbreaks.

PCR testing and molecular analysis were performed on pig tissue samples. Veterinary services conducted epidemiological investigations, forward and backward tracing, and surveillance. Farm management and biosecurity practices were assessed. Quarantine, culling, carcass disposal, and disinfection were implemented.

ASF virus genotype I was detected. A concurrent ASF outbreak in neighbouring Mpumalanga Province was identified as a possible source. Inadequate biosecurity measures probably facilitated viral transmission. Potential mechanisms for the introduction of the ASF virus include swill feeding practices, free roaming of pigs, scavenging, illegal slaughter, and trade of pig products within the community.

Molecular typing of the ASF virus linked the outbreak to an ongoing ASF outbreak in Mpumalanga Province. Pig enterprises with poor biosecurity practices may face greater risk of ASF introduction. Small-scale pig keepers should be targeted for ASF awareness and education campaigns. Innovative and cost-effective biosecurity solutions are needed in this resource-poor setting.

The aim of this study was to evaluate the efficacy and safety of sofosbuvir/ledipasvir ± ribavirin in Malagasy patients with hepatitis C virus genotypes 1 and 2, in real conditions.

This was a retrospective monocentric clinical study, carried out over a period of 3 years from March 1, 2017 to February 28, 2020, in a hospital hepato-gastroenterology department.

In total, 26 patients (M/F 11/15) with hepatitis C virus genotype 1 (n = 13) or genotype 2 (n = 13), were treated with sofosbuvir/ledipasvir without (n = 21) or with (n = 5) ribavirin for 12 weeks. The mean age was 61.38 ± 7.09 years. Seventeen patients (65.4%) had cirrhosis. The overall sustained virological response was 96.2% (95% CI = 80.4-99.9%). click here There was no significant difference between the sustained virological responses of genotypes 1 and 2 (92.3% vs 100%; p = 0.31) or those of cirrhotic or non-cirrhotic patients (94.1% vs 100%; p = 0.46). A relapse was observed in one patient (5.9%) - cirrhotic and genotype 1b - under sofosbuvir/ledipasvir with ribavirin. Seven patients (26.9%) experienced mild adverse reactions, including asthenia (57.1%) and insomnia (42.9%).

Treatment with sofosbuvir/ledipasvir ± ribavirin for infection with hepatitis C virus genotype 1 has been shown to be safe and effective, even in the presence of cirrhosis. The sofosbuvir/ledipasvir combination is a good option for genotype 2 non-cirrhotic patients.

In August 2020, an outbreak of Shiga toxin-producing Escherichia coli (STEC) O157H7 occurred in the United Kingdom. Whole genome sequencing revealed that these cases formed a genetically distinct cluster.

Hypotheses generated from case interviews were tested in analytical studies, and results informed environmental sampling and food chain analysis. A case-case study used non-outbreak 'comparison' STEC cases; a case-control study used a market research panel to recruit controls.

A total of 36 cases were identified; all cases reported symptom onset between August 3 and August 16, 2020. The majority of cases (83%) resided in the Midlands region of England and in Wales. A high proportion of cases reported eating out, with one fast-food restaurant chain mentioned by 64% (n = 23) of cases. Both the case-case study (adjusted odds ratio (aOR) 31.8, 95% confidence interval (CI) 1.6-624.9) and the case-control study (aOR 9.19, 95% CI 1.0-82.8) revealed statistically significant results, showing that the consumption of a specific fast-food product was independently associated with infection.

Consumption of a specific fast-food product was a likely cause of this outbreak. The only ingredient specific to the product was cucumbers. The supply of cucumbers was immediately halted, and no further cases have been identified.

Confirm existence of COVID-19 outbreak, conduct contact tracing, and recommend control measures.

Two COVID-19 cases in Sana'a Capital met the WHO case definition. Data were collected from cases and contacts who were followed for 14 days. Nasopharyngeal swabs were taken for confirmation by Polymerase Chain Reaction (PCR).

Two confirmed Yemeni male patients aged 20 and 40 years who had no travel history were admitted to hospital on 24 April 2020. Regarding the first patient, symptoms started on April 18th, 2020 then the patient improved and was discharged on May 5th, while the second patient's symptoms started on April 22nd but the patient died on April 29th, 2020. Both patients had 54 contacts, 17 (32%) were health workers (HWs). Four contacts (7%) were confirmed, two of them were HWs that needed hospitalization. The secondary attack rate (sAR) was 12% among HWs compared to 5% among other contacts.

First COVID-19 outbreak was confirmed among Yemeni citizens with a high sAR among HWs. Strict infection control among HWs should be ensured. Physical distancing and mask-wearing with appropriate disinfecting measures should be promoted especially among contacts. There is a need to strengthen national capacities to assess, detect, and respond to public health emergencies.

Determining the dynamics of maternally transferred antibodies against measles, mumps, and rubella infections in infants is important for making evidence-based policy decisions regarding the timing of vaccination.

The levels of serum immunoglobulin G (IgG) developed against measles, mumps, and rubella infections were assessed using commercial ELISA kits in mother-newborn pairs (n = 294) and 6-12-month-old infants (n = 280) recruited from Colombo District, Sri Lanka. Antibody levels of mothers and their newborns were assessed with respect to sex and parity. Antibody levels and the protection conferred were assessed in a sample of infants who completed 6-12 months of age in relation to their age and sex. Antibody levels were compared between different age and sex groups using the Mann-Whitney U-test, and correlations of antibody titers were performed using the Spearman correlation test.

The prevalence rates of seropositivity for measles, mumps, and rubella were 91.5%, 89%, and 88%, respectively, in mothers remain vulnerable to infections before the first dose of the MMR vaccine.Compared with privately insured patients, recipients of Medicaid have been reported to have worse outcomes in several clinical conditions and following various surgical and medical procedures. However, the relationship between health insurance status and allogeneic hematopoietic cell transplantation (alloHCT) outcomes among patients with sickle cell disease (SCD) is not well described. We sought to compare alloHCT outcomes between patients with SCD who underwent alloHCT while enrolled on Medicaid versus those who underwent alloHCT while covered by private health insurance. We conducted a retrospective multicenter study using data reported to the Center for International Blood and Marrow Transplant Research. US patients enrolled on Medicaid or private insurance who underwent a first alloHCT for SCD between 2008 and 2018 were eligible for this study. The primary outcome was event-free survival (EFS), defined as time to death or graft failure. Secondary outcomes included overall survival (OS), graft failure, acute graft-versus-host disease (GVHD), and chronic GVHD.
