Capsule endoscopy for obscure gastrointestinal bleed in the tropics: A single-center experience on 350 patients.

BACKGROUND: Obscure gastrointestinal bleed (OGIB), now called small bowel bleed (SBB), comprises 5% to 10% of all gastrointestinal (GI) bleed episodes and capsule endoscopy (CE) is a tool for its evaluation. Studies on CE in a large sample of SBB patients from the tropics are limited. METHODS: We did a retrospective analysis of a prospectively maintained database of patients with SBB undergoing CE using PillCam or MiroCam CE. RESULTS: Of 350 patients (age 52.4 ± 17.4 years; 248 [70.9%] male) undergoing CE, 243 (69.4%) and 107 (30.6%) had overt and occult SBB, respectively. CE detected lesions in 244 (69.7%) patients (single lesion in 172 [49.1%]; multiple in 72 [20.6%]). The single lesions included vascular malformations (52, 14.9%), ulcer/erosion (47, 13.4%), tumor (24, 6.9%), hookworm (19, 5.4%), stricture (15, 4.3%), hemobilia (1, 0.3%) and blood without identifiable lesion (9, 2.6%). Of 72 with multiple lesions, ulcer with stricture was the commonest finding (n = 43, 12.3%). No abnormality was detected in 106 (30.3%) patients. The frequency of lesion detection was comparable among patients with overt and occult SBB (173/243, 71.2% vs. 71/107, 66.3%, respectively; p = 0.4). Younger patients (0 to 39 years) more often had multiple lesions on CE than the older (≥ 40 years) ones (26/76, 34.2% vs. 46/228, 20.2%, respectively; p = 0.001). CONCLUSION: CE has a high diagnostic yield in SBB in the tropics, regardless of the type of bleed or of CE brand and the duration of recording. Multiple lesions associated with SBB are commoner among younger (< 40 years) patients.

Congenital Diarrhoea In A Neonate With Hypernatraemia And Dehydration.

Diarrhoea, vomiting, and dehydration are frequently encountered in neonatal emergency. However, it is challenging to manage resistant hypernatraemia and metabolic acidosis associated with it. Diagnosing the exact cause is even more difficult. Glucose-galactose malabsorption commonly presents with hypernatraemia and repeated dehydration. In the case described here, the baby started to have diarrhoea in the first week of life and presented in the neonatal emergency with severe dehydration and hypernatraemia. Higher sodium levels were difficult to manage throughout the course of illness. Hypernatraemia and diarrhoea worsened on feeding, whether formula or mother's feed, which raised suspicion of glucose and galactose malabsorption. So, genetic testing was performed and fructose based formula was started which led to improvement in the condition. Later, genetic testing confirmed our diagnosis. This case report emphasises that clinicians should consider the possibility that congenital diarrhoea could be due to glucose- galactose malabsorption while managing a case with loose stool and significant electrolyte imbalance in a neonate.

Introducing Birth Companion in Labour: A Quality Improvement Initiative.

Background: Birth companion (BC) has been globally recognised as an essential component of childbirth care. As our institution did not allow BC in labour, this study was planned as a quality improvement (QI) project to introduce the concept. We aimed to achieve birth companionship from existing 0 to 100% over a period of six months. Intervention: QI team was constituted, and an initial brainstorming session conducted. A fishbone diagram was drawn to analyse issues that need addressal before implementation of the initiative. The framework was defined, and team members assigned their roles and responsibilities. A series of five successive Plan-Do-Study-Act (PDSA) cycles were carried out over a period of six months, which included introduction of the concept, dissemination of information, infrastructural changes in labour room and introducing column for documentation in birth register. To achieve sustainability, comprehensive group counselling sessions were started for women during antenatal period, and sensitisation classes were regularly conducted for newly inducted trainees and faculty. Result: Birth companionship was achieved in 98% of cases. Conclusion: The QI tools helped in preparation and planning of changes by breaking down a large problem into smaller sections and covering all aspects of challenges in a systematic manner using team-based approach. National directives and recommendations, sensitisation of leadership and training of stakeholders were found to be important facilitators. Robust systems of monitoring and successive PDSA cycles were needed for continuous improvement and sustainability of the idea.

Twenty-four-hour pH metry alone is inferior to additional impedance monitoring in the diagnosis of gastroesophageal reflux disease, particularly in presence of reduced gastric acid secretion.

BACKGROUND: Current gold standard for the diagnosis of gastroesophageal reflux disease (GERD) is 24-hour pH metry though it fails to detect non-acidic reflux. The sensitivity of 24-hour pH metry alone (both catheter-based and Bravo capsule) is questionable, especially if gastric acid secretion is low due to reduced parietal cell mass, Helicobacter pylori-induced gastric atrophy and antisecretory therapy. Accordingly, we analyzed the diagnostic ability of 24-hour pH metry as compared to impedance monitoring in relation to the gastric pH without antisecretory therapy. METHODS: A retrospective analysis of prospectively collected data from 150 patients with suspected GERD undergoing a 24-hour pH impedance study was done. RESULTS: Among 150 patients with symptoms suggestive of GERD, 106 (70.6%) had confirmed GERD diagnosed either by 24-hour pH metry alone (10 [9.4%]), impedance monitoring alone (49 [46.2%]) or both (47 [44.3%]). Abnormal reflux of acidic and non-acidic gastric contents was detected by 24-hour pH metry and 24-hour impedance monitoring in 57/106 (53.7%) and 96/106 (90.5%) of patients, respectively (p < .00001). Patients with GERD diagnosed by 24-hour impedance monitoring had a higher mean gastric pH (2.9 [median 1.3, IQR 5.3]) than those diagnosed by 24-hour pH metry (2.1 [median 1.4, IQR 2.6]) or both (1.6 [median 1.2, IQR 2.1]) (p = 0.001). CONCLUSION: Twenty-four-hour impedance monitoring detects GERD more often than 24-hour pH metry. Patients with higher mean gastric pH leading to non-acidic reflux were more often diagnosed by 24-hour impedance monitoring than 24-hour pH metry. Thus, 24-hour pH metry alone is inferior to additional impedance monitoring in the diagnosis of GERD, particularly in presence of reduced gastric acid secretion.

True peristaltic recovery is uncommon following treatment, particularly endoscopic dilation for achalasia cardia, though pseudo-recovery often occurs.

BACKGROUND: Relieving esophagogastric junction (EGJ) obstruction has been the focus of treatment for achalasia cardia. The recovery of peristalsis has been an elusive goal. Studies analyzing post-intervention peristaltic recovery have several limitations such as the use of conventional manometry or lack of standard definitions of peristalsis. Accordingly, we undertook this study to analyze frequency and pattern of peristaltic recovery following treatment for achalasia cardia on high-resolution manometry (HRM) and standard Chicago definition of peristalsis. METHODS: Pre and post-intervention HRM records of 71 treatment-naive patients diagnosed as achalasia cardia were retrospectively analyzed. Records with pre and post-intervention HRM on different systems (e.g. solid state and water perfusion) and those with inadequate information were excluded. All HRMs were interpreted as per Chicago classification version 3.0. After pneumatic dilation (PD) or laparoscopic Heller's myotomy (LHM), pseudorecovery of peristalsis was defined as any contraction at least 3 cm in length along 20 mmHg isobaric contour with a distal latency of less than 4.5 seconds. True recovery and premature contractions were defined by standard Chicago classification v3.0 criteria. RESULTS: Change in diagnosis was observed in 38 of 71 (53.5%) patients after intervention. While pseudo-peristaltic recovery occurred in 11 of 71 (15.5%) patients, only three (4.2%) had a true recovery. Another nine (12.7%) patients showed new premature contractions. CONCLUSION: True peristaltic recovery is uncommon in achalasia cardia following intervention, particularly PD. Pseudo-peristaltic recovery is more common. Further research is warranted on this issue.

Efficacy and safety of surfactant administration by MIST and INSURE techniques in Neonates with Respiratory Distress Syndrome: A randomized controlled trial.

Objective: To measure the efficacy and safety of surfactant administered by MIST and INSURE to neonates with respiratory distress syndrome. Methods: A randomized controlled trial was conducted from June 2021 to August 2022 at the NICU of the University of Child Health Sciences, Lahore. Neonates meeting inclusion criteria i.e with RDS who worsened on nasal Continuous positive airway pressure (nCPAP) (fiO2 30%, pressure 6cmH2O) were enrolled in the study in both interventional arms (MIST, n=36 and INSURE, n=36) using simple random sampling. Data was analysed using SPSS 25. Results: The mean age of neonates in MIST was 1.27±0.40 days and 1.23±0.48 days in INSURE cohort. Neonates with MIST (n=8) required statistically significant reduced need for IMV than INSURE (n=17) technique (P-Value 0.047). This study could not achieve significant difference in duration of mechanical ventilation (1±1.67; 1.52±1.40 days, P=0.152) and duration of nCPAP (3.27±1.65;3.67±1.64 hrs, P=0.312) in MIST versus INSURE. The second dose of surfactant was administered in fewer cases in MIST (n=2) than INSURE (n=7) (P=0.075). Risk estimation, although not significant, determined less likelihood for the pulmonary haemorrhage (0.908 than 1.095), intraventricular hemorrhage (0.657 than 1.353), administration of the second dose of surfactant (0.412 than 1.690) and greater likelihood of discharge (1.082 than 0.270) at 95% confidence interval with MIST technique. Conclusion: Surfactant therapy through MIST is effective and there is significantly reduced need of IMV than in INSURE. Safety profile though could not achieve statistical significance yet determines less risk of complications associated with MIST than INSURE.RCT Registration Number: TCTR20210627001.

Photocatalytic removal of organic dye using green synthesized zinc oxide coupled cadmium tungstate nanocomposite under natural solar light irradiation.

In this work, zinc oxide coupled cadmium tungstate (ZnO-CT) was prepared as a nano-photocatalyst through a green synthesis route using lemon leaf extract and characterized based on diverse microscopic and spectroscopic techniques. To explore the applicabilties of the prepared nanocomposite (NC), its photocatalytic activity has been investigated against Congo red (CR) dye under natural solar light irradiation conditions. ZnO- CT nano-photocatalyst showcases 97% photocatalytic degradation of the CR after 90 min of natural solar light irradiation with quantum yield of 1.16 × 10-8 molecules photon-1. The ZnO-CT NC has shown the enhanced photocatalytic degradation performance against CR when compared to its pristine forms (e.g., ZnO (70%) or CT (44%)). According to the free radical trapping and quenching experiments, the photocatalytic activity of ZnO-CT NC appears to be driven efficiently by superoxide and hydroxyl radicals. The photocatalytic degradation kinetics for CR dye was also studied using the pseudo-first-order, diffusional, and Singh models. The high photocatalytic activity of ZnO-CT NC can be accounted for by the presence of electron-withdrawing functional groups like acids (-COOH) and aldehydes (-CHO) on its surface which helped maintain the prolonged recombination of charge carriers and enhanced stability of ZnO-CT (with moderately low leaching rate of cadmium ions (∼2-5%)).

One-Pot Facile Synthesis of CuO-CdWO4 Nanocomposite for Photocatalytic Hydrogen Production.

Hydrogen (H2) is a well-known renewable energy source that produces water upon its burning, leaving no harmful emissions. Nanotechnology is utilized to increase hydrogen production using sacrificial reagents. It is an interesting task to develop photocatalysts that are effective, reliable, and affordable for producing H2 from methanol and acetic acid. In the present study, CuO, CdWO4, and CuO-CdWO4 nanocomposite heterostructures were prepared using a cost-efficient, enviro-friendly, and facile green chemistry-based approach. The prepared CuO, CdWO4, and CuO-CdWO4 nanocomposites were characterized using X-ray diffraction pattern, Fourier-transform infrared spectroscopy, diffuse reflectance ultraviolet-visible spectroscopy, scanning electron microscopy, transmission electron microscopy, selected area electron diffraction (SAED) pattern, N2 physisorption, photoluminescence, and X-ray photoelectron spectroscopy techniques. The synthesized photocatalysts were utilized for photocatalytic H2 production using aqueous methanol and acetic acid as the sacrificial reagents under visible light irradiation. The influence of different variables, including visible light irradiation time, catalyst dosage, concentration of sacrificial reagents, and reusability of catalysts, was studied. The maximum H2 was observed while using methanol as a sacrificial agent over CuO-CdWO4 nanocomposite. This enhancement was due to the faster charge separation, higher visible light absorption, and synergistic effect between the CuO-CdWO4 nanocomposite and methanol.

Blood Lactate Levels And Lactate Clearance As Predictors Of Mortality In Neonatal Sepsis.

BACKGROUND: Sepsis is life-threatening organ dysfunction caused by dysregulated host response to infection. Aim of the study is Neonatal sepsis refers to infection involving the blood stream in neonates. It is major health problem causing neonatal mortality and morbidity in developing countries. Our study aimed to assess the correlation between lactate clearance and blood lactate levels with outcome of neonatal sepsis. METHODS: Seventy-three eligible neonates recruited with convenience sampling technique. Study was conducted at the Neonatology department, The Children's Hospital & the Institute of Child Health, Lahore. After approval from institutional review board, and informed consent of parents/guardians, neonates with sepsis were selected through a present inclusion and exclusion criteria. Data was collected with the predetermined demographics, inflammatory markers and lactate levels. RESULTS: This research revealed 37% (n=27) mortality rate among septic neonates who were having higher blood lactate levels and low lactate clearance at 6 hours of admission in nursery. Hence higher serum lactate levels and low lactate clearance (<10%) at 6 hours were significant predictors of poor outcome in septic neonates (p-Value, <0.05). The lactate level of neonates who could not survive was 5.68±1.22 as compared to who were discharged 4.11±1.14 (p-Value, <0.05). CONCLUSIONS: Higher blood lactate levels and lactate clearance of less than 10% at 6 hours of admission in nursery are significant predictors of mortality in neonatal sepsis. Early lactate stabilization and sepsis management can improve the clinical outcomes.

Accompanying effects of sewage sludge and pine needle biochar with selected organic additives on the soil and plant variables.

The effects of synthetic fertilizer and nutrient leaching are causing serious problems impacting soil function and its fertility. Mitigation of nutrient leaching and use of chemical fertilizer is crucial as fertile land adds up sustainability to climate changes. Biochar produced from agricultural bio-waste and municipal solid waste has been used for crop production and when applied in combination with organic nutrients may support mitigation of nutrient loss and adverse effects of chemical fertilizers. Different types of biochar and their application for soil enhancement have been observed, pine needle and sewage sludge derived low-temperature biochar along with compost, organic fertilizer in the form of manure and microalgal biomass may interact with soil chemistry and plant growth to impact nutrient loss and compensate the hazardous effect of chemical fertilizer, but it has not been investigated yet. This present study elaborates application of sewage sludge and pine needle biochar produced at 400 °C in an application rate of 5 % w/w and 10 t h-1 in combination with compost, manure and microalgal biomasses of Closteriopsis acicularis (BM1) and Tetradesmus nygaardi (BM2) on the growth of Chickpea (Cicer arietinum) and Fenugreek (Trigonella foenum-graecum) crop assessed in a pot experiment over a two crop (Chickpea - Fenugreek) cycle in Pakistan. Results depict that the pine needle biochar with additives has increased plant height by 104.1 ± 2.76 cm and fresh biomass by 49.9 ± 1.02 g, buffered the soil pH to 6.5 for optimum growth of crops and enhance carbon retention by 36 %. This study highlights the valorization of sewage sludge and pine needle into biochar and the effect of biochar augmentation, its impact on soil nutrients and plant biomass enhancement. The greener approach also mitigates and helps in the sustainable management of solid wastes.

Small intestinal bacterial overgrowth in patients with inflammatory bowel disease: A case-control study.

BACKGROUND: Though small intestinal bacterial overgrowth (SIBO) is known in inflammatory bowel disease (IBD), the data on it are scanty and have limitations. METHODS: Data on IBD patients undergoing glucose hydrogen breath test (GHBT) were retrospectively analyzed to evaluate the frequency and risk factors of SIBO in IBD compared to 66 healthy controls. RESULTS: Patients with IBD (n=86; 45 ulcerative colitis [UC] and 41 Crohn's disease [CD]) more often had SIBO on GHBT than the healthy subjects (16/86 [18.6%] vs. 1/66 [1.5%]; p=0.002). SIBO was commoner among patients with CD than UC (14/41 [34.1%] vs. 2/45 [4.4%]; p=0.001). The frequency of SIBO among UC patients was comparable to healthy subjects (2/45 [4.4%] vs. 1/66 [1.5%]; p=not significant [NS]). Patients with CD than those with UC had higher values of maximum breath hydrogen and a greater area under the curve for breath hydrogen. Other factors associated with SIBO included female gender (11/16 [68.8%] with vs. 21/70 [30%] without SIBO; p=0.003), and having undergone surgery (8/16 [50%] vs. 6/70 [8.6%]; p=0.0002). SIBO patients had lower levels of total serum protein and albumin than those without SIBO (6.2 ± 1.5 g/dL vs. 7.0 ± 0.9 g/dL, respectively; p=0.009 and 3.5 ± 0.9 g/dL vs. 4.0 ± 0.6 g/dL, respectively; p=0.02). CD, female gender, and surgery for IBD tended to be the independent factors associated with SIBO among IBD patients on multivariate analysis. CONCLUSIONS: Patients with IBD, particularly CD, female, and those having undergone surgery, have a higher risk of SIBO than the healthy controls.

The Neuroprotective Efficacy of Postnatal Magnesium Sulfate in Term or Near-Term Infants With Moderate-to-Severe Birth Asphyxia.

Background In Pakistan, the neonatal mortality rate is 41 per 1,000 live births and birth asphyxia is one of the leading causes of neonatal mortality and morbidity. The goal of this study was to determine whether postnatal magnesium sulfate therapy can improve short- and long-term neurological outcomes in term or near-term neonates with moderate-to-severe birth asphyxia. Methodology This prospective double-blind randomized controlled trial was conducted in the Neonatology Department of the Children's Hospital & The Institute of Child Health, Lahore. A total of 62 neonates (31 in each group) were randomized to receive either three doses of magnesium sulfate infusion at 250 mg/kg per dose, 24 hours apart (treatment group), or three doses of injection 10% distilled water infusion at 3 mL/kg, 24 hours apart (placebo group). Both groups received similar supportive care. The neurodevelopmental assessment was done at six months of age using the ShaMaq Developmental Inventory. Results Demographic data such as gestational age, mean weight, age at presentation, gender, hypoxic-ischemic encephalopathy grade, mode of delivery, and the presence of seizures at presentation were comparable between both groups. In the magnesium sulfate group, statistically significant results were seen in terms of early seizure control (p = 0.001), early initiation of feed (p = 0.002), and shorter duration of hospital stay (p = 0.003). Moreover, the magnesium sulfate group had lower mortality compared to the control group, though it was not statistically significant (p = 0.390). There was no significant difference in terms of cranial ultrasound findings between the two groups (p = 0.783) at the time of discharge. Regarding the neurodevelopmental delay, there was no significant difference between the magnesium sulfate and control groups (p = 0.535). Conclusions Postnatal magnesium sulfate treatment improves short-term neurologic outcomes at discharge in term or near-term neonates with moderate-to-severe perinatal asphyxia. However, no difference was noted in the neurodevelopmental outcome at six months.

Improvement in knowledge of healthcare professionals attending Neonatal Life Support (NeoLiS) training workshop.

OBJECTIVE: To assess the improvement in knowledge of healthcare professionals after attending Neonatal Life Support training workshop. METHODS: The interventional study with secondary data was conducted in the Neonatology Department of the Children's Hospital and the Institute of Child Health, Lahore, Pakistan, using 2-year data of all the training workshops from 2017 to 2018. The participants were consultants, post-graduate residents, nurses, lady health visitors, lady health workers and rescue workers. Knowledge was tested through a true/false questionnaire regarding resuscitation skills both before and after the hands-on workshop. The score of each candidate was recorded on a results sheet. Baselines scores were compared with respective post-workshop test. Data was analysed using SPSS 20. RESULTS: Of the 52 workshops, 35(%) were conducted in 2017 and 17(%)in 2018, and of the 1350 particpants, 1080(81%) were doctors, 257(18%) were nurses and 13(1%) were paramedics and rescue workers. Mean overall baseline score was 71.96±8.38 compared to 86.60+/-5.48 post-intervention (p<0.001). CONCLUSIONS: The Neonatal Life Support training workshop resulted in significant gain in knowledge about neonatal resuscitation by healthcare professionals.

Health insurance acceptance of female labour force: A special focus on reproductive health.

OBJECTIVE: To measure the demand for health insurance policy with special focus on maternity services among working women. METHODS: The cross-sectional study was conducted in Lahore, Pakistan, from October 15 to November 15, 2018, after approval from the Punjab Economic Research Institute, and comprised public and private school teachers of reproductive age. The primary data was collected using a structured questionnaire. Logit model was used to determine the factors affecting the interest level in maternal health insurance. RESULTS: Of the 110 teachers, 54 (49 %) were from private schools and 56 (51%) from public schools. The overall age range was 21-49 years, with 64 (58%) aged 31-40 years. Also, 79 (72%) teachers had completed 16 years of education. Of the total, 63 (57%) respondents were willing to buy maternal health insurance. Income, age, awareness and the type of preceding delivery were important determinants of the willingness to pay for maternal health insurance. CONCLUSION: Providing full insurance coverage during maternity was expected to give financial relief and to also ensure better health conditions of the teachers on re-joining the work.

CuO-ZnO-CdWO4: a sustainable and environmentally benign photocatalytic system for water cleansing.

Currently, there is a major problem of water contaminations, especially of dyes, all over the world. A new technique is being developed daily for the treatment of contaminated water. In many ways, a photocatalytic degradation of a dye by a mixed metal oxide photocatalyst is counted as the best technique for water treatment. This paper also addresses the preparation and photocatalytic application of newly developed mixed metal oxide nanocomposite, CuO-ZnO-CdWO4. A novel mixed metal oxide CuO-ZnO-CdWO4 nanocomposite has been synthesized by a green route using Brassica Rapa leaves extract. The application of CuO-ZnO-CdWO4 as a photocatalyst in wastewater treatment has been thoroughly discussed. Several spectroscopic and microscopic techniques were used to characterize the prepared nanocomposite. The photocatalytic activity of CuO-ZnO-CdWO4 nanocomposite with a band gap of 3.13 eV was observed under the artificial visible light and sunlight for the degradation of Congo red dye. The results under sunlight show the 1.45 times greater removal efficiency than under the artificial visible light. Pseudo-first-order, diffusion, and Singh kinetics models were used to describe the kinetics of dye degradation. Pseudo-first-order model was found to be best fitted model for present study. The performance of CuO-ZnO-CdWO4 was estimated by significant parameters such as quantum yield, figure of merit, turnover number, and mean turnover frequency. The value these parameters were calculated as 1.70 × 10-8 molecules photon-1, 1.77 × 10-4, 2.98 × 108 s-1, and 3.31 × 10-4 s-1, respectively. These parameters revealed high potential of CuO-ZnO-CdWO4 for Congo red dye degradation.

Facile green synthesis of ZnO-CdWO4 nanoparticles and their potential as adsorbents to remove organic dye.

In this work, ZnO-CdWO4 nanoparticles have been synthesized by the ecofriendly green method with lemon leaf extract to favorably anchor functional groups on their surface. The prepared ZnO-CdWO4 nanoparticles are used as adsorbent to treat Congo red (CR) dye after characterization through FT-IR, UV-Vis, TEM, SEM-EDX, and HRTEM techniques. The equilibrium partition coefficient and adsorption capacity values for CR by ZnO-CdWO4 are estimated as 21.4 mg g-1 µM-1 and 5 mg g-1, respectively (at an initial dye concentration of 10 mg L-1). The adsorption process is found as exothermic and spontaneous, as determined by the ΔG°, ΔS°, and ΔH° values. The Boyd plot has been used as a confirmatory tool to fit the adsorption kinetics data along with intraparticle diffusion and pseudo-second-order models. Based on this research, ZnO-CdWO4 nanoparticles are validated as an effective adsorbent for CR dye in aqueous solutions.

Staphylococci in poultry intestines: a comparison between farmed and household chickens.

Both pathogenic as well as nonpathogenic species of staphylococci have been reported in poultry, but these studies have not compared staphylococcal flora of both farmed and household broiler chickens. Staphylococci from farmed (n = 51) and household chicken intestines (n = 43) were isolated and tested for resistance to antimicrobials, presence of resistance genes, and inhibitory activity against other bacteria; correlation of resistance phenotype and genotype was also evaluated. At least 12 staphylococcal species were identified; Staphylococcus carnosus subspecies carnosus was the predominant species from both sources. Most farmed chicken staphylococci were resistant to tigecycline (38/51; 74.8%) while the highest level of resistance among the household chicken staphylococci was to clindamycin (31/43; 72.1%). The mecA gene was only detected in staphylococci from household chickens, whereas ermC and tetK or tetM were found in staphylococci from both groups of birds. Multidrug resistance (resistance ≥ 2 antimicrobial classes) was observed in 88% of resistant staphylococci ranging from 2 to 8 classes and up to 10 antimicrobials. Isolates produced inhibitory activity against 7 clinical bacterial strains primarily Enterococcus faecalis (25/88; 28.4%) and Escherichia coli (22/88; 25%). This study demonstrated that the staphylococcal population among farmed and household chickens varies by species and resistance to antimicrobials. These results may reflect the influence of the environment or habitat of each bird type on the intestinal microflora. As resistance in the staphylococci to antimicrobials used to treat human infections was detected, further study is warranted to determine strategies to prevent transfer of these resistant populations to humans via contamination of the poultry meat.

A pragmatic evaluation of trauma care: an evidence from the province of Punjab, Pakistan.

Road Traffic Accident (RTA) injuries pose a public health challenge which significantly impacts the human capital development. The Punjab Economic Research Institute (PERI) conducted a study to assess the frequency, causes of trauma injuries, distribution and need and gap analysis of trauma centers in the province of Punjab. For gap/situational analysis, information was extracted through a structured questionnaire from randomly selected 8 District Head Quarters hospitals, 6 Teaching hospitals and 8 independent trauma centers. According to the data of Rescue 1122, 70% of RTA injuries involved the age group 11-40 years. In 295589(63.26%) of the RTA cases the vehicle involved was a motorbike. The major RTA injuries were leg fractures 71699 (16.44%) and head injuries 44738(10.26%). Over speeding 159977(44%) and careless driving 121545 (33.35%) were the major causes of RTAs. Noted was a shortage and mismatch between human resources and equipment in the trauma treatment facilities. Inequality was also found in distribution of trauma care units. Integrated and fully equipped trauma care system along with the establishment of trauma centers in places of high accidents' frequency is recommended. Strict implementation of road traffic safety laws is mandatory.

Detection and Molecular Characterization of Staphylococci from Eggs of Household Chickens.

Eggs are a healthy and nutritious food source, but may be contaminated by bacteria. Previous studies have reported the presence of staphylococci in eggs of farmed chickens, but no study has evaluated the staphylococcal population of eggs from household chickens. In this study, staphylococci from eggs (n = 275) of household chickens collected from November 2016 to March 2017 from different villages of Khyber Pakhtunkhwa province, Pakistan, were characterized. Seven species of staphylococci were identified from 65 eggs, including the predominant species, Staphylococcus xylosus (49/275; 17.8%). S. xylosus isolates (n = 73) were tested for antimicrobial susceptibility, presence of resistance genes, genetic relatedness, and inhibitory activity against other bacteria. The majority of isolates were resistant to oxacillin (83.6%) and tetracycline (24.7%), but also exhibited resistance to daptomycin and linezolid (5.5% each). Of the 10 resistance genes tested, isolates were only positive for mecA (35.6%; 26/73), mecC/C1 (2.7%; 2/73), and tet(K) (14/73; 19%). Using pulsed-field gel electrophoresis (PFGE), nine clusters had identical PFGE patterns. Isolates produced inhibitory activity against a broad spectrum of bacteria; 20.5%, 19.2%, 17.8%, and 16.4% of S. xylosus were able to inhibit growth of Salmonella enterica serotype Typhi, methicillin-susceptible Staphylococcus aureus, Escherichia coli, and methicillin-resistant Staphylococcus aureus, respectively. This study demonstrated the presence of genetically related antimicrobial-resistant S. xylosus from eggs from household chickens. Like table eggs, eggs of household chickens also contain staphylococci that may be resistant to antimicrobials used to treat human infections. These data will allow comparison between staphylococci from eggs from different sources and may indicate the relative safety of eggs from household chickens. Further study of these egg types and their microbial composition is warranted.
