Abstract
BackgroundNosocomial infections are a global health problem, affecting 1.4 million people in treatment centers, responsible for 80,000 estimated annual deaths. The current study aimed to assess the factor influencing nosocomial infections and to choose the best antibiotic for its treatment through culture analysis.MethodologyThe current study was conducted in a tertiary care hospital Rawalpindi. A total of 120 patients with at least one nosocomial episode were included. Blood, urine, and wound swab sample were collected for hematology, biochemistry, electrolyte, and microbial analysis. Multivariate regression analysis through SPSS (ver. 16.0) were done, p-value of ≤ 0.05 was considered statistically significant.ResultThe prevalence of culture-confirmed nosocomial infection was 25%, among which age groups (P = 0.00, 95% CI, − .382-.271) were significantly correlated. Hematological analysis shows that 73.3% have lymphopenia (P = 0.00, 95% CI .567-1.175), 73.3% have Neutrocytosis (P = 0.00, 95% CI .553-1.122) and anemia (26.7%) (P = 0.002, 95% CI .097-.404) were statistically significant. Raised level of ALT (60%), Bilirubin (26.7%) and ALP (13.3%) among liver functional tests (P = 0.68, 95% CI .686- .280) found insignificant however abnormal level of urea (33.3%) and creatinine (46.7%) (P = 0.00, 95% CI -1.227-.392) were significantly correlated with nosocomial infections. Electrolytes profile shows that Hypernatremia (26.7%) (P = 0.000, 95% CI-.491–.227) were strongly correlated. Culture analysis isolated six bacterial agents, comprising 83.3%:16.6% ratio of gram-negative and gram-positive isolates. Klebsiella pneumonia was frequently isolated gram-negative, while Methicillin-Resistant Staphylococcus aureus was the only gram-positive isolate collected. Urinary tract infection (UTI) (36.6%) was frequently found, followed by bloodstream infection (26.6%) (BSI). The majority of the gram-negative isolates were sensitive to Imipenem while resistant to Amoxicillin + Clavulanic acid, Trimethoprim/sulfamethoxazole, cefoxitin, Levofloxacin, Norfloxacin, and linezolid antibiotics. Methicillin-resistant staphylococcus aureus was found sensitive against Trimethoprim/sulfamethoxazole while resistant towards linezolid, Imipenem, and Cefotaxime.ConclusionThe current study revealed that nosocomial infection is still prevalent in our hospital environment and the leading cause of drug resistance and dysfunctions of various factors like WBCs, LFTs, RFTs, electrolytes, coagulation factors and anemia, which can lead to morbidity and mortality.

Abstract
BackgroundOvercrowding, abuse of antibiotics and increase of antimicrobial resistance negatively affect neonatal survival rates in developing countries. We aimed to define pathogens and their antimicrobial resistance (AMR) of early-onset sepsis (EOS), hospital-acquired late-onset sepsis (HALOS) and community-acquired late-onset sepsis (CALOS) in 25 neonatal intensive care units (NICUs) in China.Study designThis retrospective descriptive study included pathogens and their AMR from all neonates with bloodstream infections (BSIs) admitted to 25 tertiary hospitals in China from January 1, 2017, and December 31, 2019. We defined EOS as the occurrence of BSI at or before 72 hours of life and late-onset sepsis (LOS) if BSI occurred after 72 hours of life. LOS were classified as CALOS if occurrence of BSI was ≤ 48 hours after admission, and HALOS, if occurrence was > 48 hours after admission.Results1092 pathogens of BSIs collected from 25 NICUs including 349 EOS isolates, 702 HALOS isolates and 41 CALOS isolates. Gram-negative bacteria (GNB) dominated in EOS (56.7%) and HALOS (62.2%). The most frequent pathogens causing EOS were Escherichia coli (27.2%) and group B streptococcus (GBS; 14.6%) whereas in CALOS they were GBS (46.3%) and Staphylococcus aureus (41.5%). Klebsiella pneumonia (27.9%), Escherichia coli (15.7%) and fungi (12.8%) were the top three isolates in HALOS. Third-generation cephalosporin resistance rates in GNB ranged from 9.7–55.6% in EOS and 26–63.3% in HALOS. Carbapenem resistance rates in GNB ranged from 2.7–31.3% in HALOS and only six isolates in EOS were carbapenem resistant. High rates of multidrug resistance were observed in Klebsiella pneumonia (60.7%) in HALOS and in Escherichia coli (44.4%) in EOS. All gram-positive bacteria were susceptible to vancomycin except for three Enterococcus faecalis in HALOS. The adverse outcome rates in HALOS were high, ranging from 4.6–16.2%.ConclusionsEscherichia coli, Klebsiella pneumonia and GBS were the leading pathogens in EOS, HALOS and CALOS, respectively. The high proportion of pathogens, high degree of antimicrobial resistance and high proportion of adverse outcomes in HALOS underscore understanding of the pathogenesis and devise effective interventions in developing countries.

Published: January 2021

Abstract
In this paper, a stochastic SEITR model is formulated to describe the transmission dynamics of tuberculosis with incompletely treated. Sufficient conditions for the existence of a stationary distribution and extinction are obtained. In addition, numerical simulations are given to illustrate these analytical results. Theoretical and numerical results show that large environmental perturbations can inhibit the spread of tuberculosis.

Abstract
Background: The giant freshwater prawn (Macrobrachium rosenbergii) is a commercially valuable freshwater crustacean species that is cultivated throughout the world. M. rosenbergii is frequently affected by a variety of diseases. Therefore, feed additive research is necessary to improve the immunity and survival rate of M. rosenbergii. Scutellaria polysaccharide (SPS) extracted from Scutellaria baicalensis (a Chinese medicinal herb) can enhance the antioxidant ability of organisms. Methods: In this study, M. rosenbergii were fed with 50 mg/kg, 100 mg/kg, and 150 mg/kg of SPS. Following a four-week feeding trial, SPS had no positive effect on the growth of M. rosenbergii compared with the control group. Then, the immunity and antioxidant capacity of M. rosenbergii were tested by qRT-PCR and enzyme activities. Results: The results showed that the expressions of prophenoloxidase (proPO) and toll receptor (Toll-R) mRNA showed no changes in hemocytes of M. rosenbergii. However, the expressions of heat shock protein 70 (HSP70) and nuclear factor κB (NF-κB) mRNA were up-regulated during the first two weeks of culture and were down-regulated in weeks 3 and 4. The mRNA expressions of HSP70, NF-κB, and Toll-R (participating in the immune response) in heart, muscle, and hepatopancreas were decreased after four weeks of SPS feeding. This indicated that long-term feeding of SPS could regulate the immune responses of M. rosenbergii. The activity levels of antioxidant biomarkers, alkaline phosphatase (ACP), acid phosphatase (AKP), polyphenol oxidase (PPO), catalase (CAT), and superoxide dismutase (SOD), in hemocytes, heart, muscle, and hepatopancreas increased during the feeding time, indicating that the antioxidant capacity of M. rosenbergii was improved by SPS supplementation in the feed. Conclusions: In summary, SPS was conducive to enhancing the antioxidant capacity of M. rosenbergii. These results provide a theoretical basis in supporting of SPS addition to the feed of M. rosenbergii.
Host-cell recognition through GRP78 is enhanced in the new UK variant of SARS-CoV-2, in silico&nbsp;

Abstract
New SARS-CoV-2 variant VUI 202012/01 started in the UK and currently spreading in Europe and Australia during the last few days. The new variant bears about nine mutations in the spike protein (Δ69-70, Δ145, N501Y, A570D, D614G, P681H, T716I, S982A, and D1118H). The N501Y lies in the receptor-binding domain (RBD) of the spike and interacts with the host-cell receptor ACE2 responsible for viral recognition and entry. We tried to simulate the system of ACE2-SARS-CoV-2 spike RBD in the wildtype and mutated isoform of the RBD (N501Y). Additionally, the GRP78 association with the ACE2-SARS-CoV-2 spike RBD is modeled at the presence of this mutant variant of the viral spike.

Abstract
Background: Campylobacter jejuni (C. jejuni) is a leading cause of acute gastroenteritis in human worldwide. The aim of study was to assess the distribution of sialylated lipooligosaccharide (LOS) classes and capsular genotypes in C. jejuni isolated from Iranian children with gastroenteritis. Furthermore, the level of dnaK gene expression in C. jejuni strains with selected capsular genotypes and LOS classes was intended. Moreover, a comprehensive study of C. jejuni MLST-genotypes and inclusive comparison with peer sequences worldwide was intended.Methods: Twenty clinical C. jejuni strains were isolated from fecal specimens of 280 children aged 0-5 years, suspected of bacterial gastroenteritis, which admitted to 3 children hospitals from May to October, 2018. Distribution of sialylated LOS classes and specific capsular genotypes were investigated in C. jejuni of clinical origin. The expression of dnaK in C. jejuni strains was measured by Real-Time-PCR. MLST-genotyping was performed to investigate the clonal relationship of clinical C. jejuni strains and comparison with inclusive sequences worldwide.Results: C. jejuni HS23/36c was the predominant genotype (45%), followed by HS2 (20%), and HS19 and HS4 (each 10%). A total of 80% of isolates were assigned to LOS class B and C. Higher expression level of dnaK gene was detected in strains with HS23/36c, HS2 and HS4 capsular genotypes and sialylated LOS classes B or C. MLST analysis showed that isolates were highly diverse and represented 6 different sequence types (STs) and 3 clonal complexes (CCs). CC21 and CC257 were the most dominant CCs (75%) among our C. jejuni strains. No new ST and no common ST with our neighbor countries was detected. Conclusions: The C. jejuni isolates with LOS class B or C, and capsular genotypes of HS23/36, HS2, HS4 and HS19 were dominant in population under study. The CC21 and CC257 were the largest CCs among our isolates. In overall picture, CC21 and CC353 complexes were the most frequently and widely distributed clonal complexes worldwide, although members of CC353 were not detected in our isolates. This provides a universal picture of movement of dominant Campylobacter strains worldwide.

Abstract
BackgroundSince there was no previous report, we analyzed the relationship between French Risk Stratification parameters in pulmonary arterial hypertension (PAH) and mean pulmonary arterial pressures (mPAP) using Japan PH Registry (JAPHR) national-wide cohort.MethodsWe enrolled 108 patients with PAH from JAPHR from previous reported cohort and analyzed the relations between French Risk Stratification scores and hemodynamic improvements.ResultsThe ratio meeting 0 to 4 French Risk Stratification score was 21.3%, 31.5%, 32.4%, 13.0%, and 1.9% at baseline, and 6.5%, 23.2%, 33.3%, 23.2%, 13.9% at follow-up, respectively. The improvements in the number of criteria met were associated both with mPAP at follow-up (p=0.03) and with the improvements in mPAP (p<0.001).ConclusionThe improvements in French Risk Stratification may become a marker of improved hemodynamics including mPAP.

Abstract
Background: There are no accurate estimates of the prevalence of non-severe maternal morbidities. Given the lack of instruments to fully assess these morbidities, the World Health Organization (WHO) developed an instrument called WOICE. Objective: To evaluate the prevalence of non-severe maternal morbidities in puerperal women and factors associated to impaired clinical, social and mental health conditions. Method: A cross-sectional study with postpartum women at a high-risk outpatient clinic in southeast Brazil, from November 2017 to December 2018. The WOICE questionnaire included three sections: the first with maternal and obstetric history, sociodemographic data, risk and environment factors, violence and sexual health; the second considers functionality and disability, general symptoms and mental health; and the third includes data on physical and laboratory tests. Data collection was supported by Tablets with REDCAP software. Initially, a descriptive analysis was performed, with general prevalence of all variables contained in the WOICE, including scales on anxiety and depression (GAD-7 and PHQ-9- impaired if ≥10), functionality (WHODAS- high disability scores when ≥37.4) and data on violence and substance use. Subsequently, an evaluation of cases with positive findings was performed, with a Poisson regression to investigate factors associated to impaired non-clinical and clinical conditions. Results: 517 women were included, majority (54.3%) multiparous, between 20 and 34 years (65.4%) and with a partner (75,6%). Over a quarter had (26.2%) preterm birth. Around a third (30.2%) reported health problems informed by the physician, although more than 80% considered having good or very good health. About 10% reported any substance use and 5.9% reported exposure to violence. Anxiety was identified in 19.8% of cases, depression in 36.9% and impaired functioning in 4.4% of women. Poisson regression identified that poor overall health rating was associated to increased anxiety/depression and impaired functioning. Having a partner reduced perception of women on the presence of clinical morbidities. Conclusion: During postpartum care of a high-risk population, over one third of the considered women presented anxiety and depression; 10% reported substance use and around 6% exposure to violence. These aspects of women´s health need further evaluation and specific interventions to improve quality of care.

Published: January 2021

Abstract
Soil microbes perform important functions in nitrogen and carbon cycling in the biosphere. Microbial communities in the rhizosphere enhance plants’ health and promote nutrient turnover and cycling in the soil. In this study, we evaluated the effects of soil fertilization with organic and inorganic fertilizers on the abundances and distribution of carbon and nitrogen cycling genes within the rhizosphere of maize plants. Our result showed that maize plants through rhizosphere effects selected and enriched the same functional genes glnA, gltB, gudB involved in nitrogen cycle as do high compost and low inorganic fertilizer treatments. This observation was significantly different from those of high doses of inorganic fertilizer and low compost manure treated soil. Only alpha amylase encoding genes were selectively enriched by low compost and high inorganic fertilized soil. The other treatments only selected xynB (in Cp8), lacZ (Cp4), bglA, pldB, trpA (N2), uidA (N1) and glgC, vanA (Cn0) carbon cycling genes in the rhizosphere of maize. Also Actinomycetales are selected by high compost, low inorganic fertilizer and control. The control was without any fertilization and the soil was planted with maize. Bacillales are also promoted by low compost and high inorganic fertilizer. This indicated that only microbes capable of tolerating the stress of high dose of inorganic fertilizer will thrive under such condition. Therefore, soil fertilization lowers nitrogen gas emission as seen with the high abundance of nitrogen assimilation genes or microbial anabolic genes, but increases carbon dioxide evolution in the agricultural soil by promoting the abundance of catabolic genes involve in carbon cycling.

Abstract
Background Post-term pregnancy is associated with an increased risk of maternal complications, respiratory distress and trauma to the neonate. Amniotic membrane sweeping has been recommended as a simple procedure to promote the spontaneous onset of labour. However, despite its widespread use, there is an absence of evidence on a) its effectiveness and b) its optimal timing and frequency. The primary aim of the MILO study is to inform the optimal design of a future definitive randomised trial to evaluate the effectiveness (including optimal timing and frequency) of membrane sweeping to prevent post-term pregnancy. We will also assess the acceptability and feasibility of the proposed trial interventions to clinicians and women (through focus group interviews).Methods/Design Multicentre, pragmatic, parallel group, pilot randomised controlled trial with an embedded factorial design. Pregnant women with a live, singleton fetus ≥ 38 weeks gestation, cephalic presentation, longitudinal lie, intact membranes, English speaking and ≥18 years of age will be randomised in a 2:1 ratio to:Membrane sweep versus no membrane sweep Women allocated randomly to a sweep will then be randomised further (factorial component) to:early (from 39 weeks) versus late (from 40 weeks) sweep commencement; and a single verses weekly sweep The proposed feasibility study consists of four work packages i.e., (1) a multicentre, pilot randomised trial, 2) a health economic analysis and 3) a qualitative study (4) a study within the host trial (a SWAT). Outcomes to be collected include: recruitment and retention rates, compliance with protocol, randomisation and allocation processes, attrition rates and cost-effectiveness. Focus groups will be held with women and clinicians to explore the acceptability and feasibility of the proposed intervention, study procedures and perceived barriers and enablers to recruitment.Discussion The primary aim of the MILO study is to inform the optimal design of a future definitive randomised trial to evaluate the effectiveness (including optimal timing and frequency) of membrane sweeping to prevent post-term pregnancy. Results will inform whether and how the design of the definitive trial as originally envisaged should be delivered or adapted.Trial Registration ClinicalTrials.gov, ID: NCT04307199.

Abstract
Background: Due to the lack of a sensitive, specific and rapid detection method, aetiological diagnosis of pneumonia caused by Mycoplasma pneumoniae (M. pneumoniae, MP) is a constantly challenging issue. This retrospective study aimed to compare the diagnostic methods for Mycoplasma pneumoniae in children and evaluate their values.Methods: From November 2018 to June 2019, 830 children with community-acquired pneumonia were selected from the Department of Respiratory Medicine, Shanghai Children's Medical Center. On the first day of hospitalization, sputum, throat swab and venous blood samples were collected to analyse MP-IgM (particle agglutination, PA), MP-IgM (immune colloidal gold technique, GICT), MP-DNA, MP-RNA (simultaneous amplification and testing, SAT) and MP-DNA (real-time polymerase chain reaction, RT-PCR).Results: Among these 830 children, RT-PCR showed that the positive rate was 36.6% (304/830), in which the positive rate of macrolide resistance (A2063G mutation) accounted for 86.2% of cases (262/304). Using RT-PCR as the standard, MP-RNA (SAT) had the highest specificity (97.5%), and MP-IgM (PA) had the highest sensitivity (74.0%) and Youden index (53.7%). If MP-RNA (SAT) was combined with MP-IgM (PA), its Kappa value (0.602), sensitivity (84.2%), specificity (78.7%) and Youden index (62.9%) were higher than those of single M. pneumoniae detection.Conclusions: Our research indicated that a combination of MP-RNA (SAT) plus MP-IgM (PA) might lead to reliable results as an early diagnostic method for children with clinical manifestations of Mycoplasma pneumoniae pneumonia.
