Functional outcome of crossed Kirschner wire fixation in pediatric supracondylar humerus fracture
Background: Distal humeral fractures are one of the most common types of fractures in children, most of them being supracondylar. Supracondylar fractures are usually caused by trauma, most likely falls. It is an emergency, requiring rapid diagnosis and management to avoid serious complications. Recommended treatment modalities vary from no reduction and immobilization to open reduction and internal fixation. Kirschner wire (K-wire) fixation of displaced supracondylar fractures after closed reduction is a preferred method and is being performed for over 50 years now. This study was conducted to determine the functional outcome of crossed K-wire fixation in pediatric supracondylar fracture.Methods: This prospective study was conducted from May-November 2018 at the department of Orthopedics, Abbasi Shaheed Hospital, Karachi, Pakistan. It was inferred that functional outcome of pediatric displaced supracondylar humeral fractures is satisfactory when managed with percutaneous crossed K-wire fixation. It included 83 children with supracondylar fractures. They were treated with percutaneous crossed K-wire fixation. Patients were then followed up to determine satisfactory functional outcome according to Flynnâs criteria. Data entry and analysis was done using SPSS 21.0.Results: Eight-three patients were included. The mean±standard deviation age of this study population was 7.03±3.39 years. Out of the study participants, 47 (56.6%) were males and 36 (43.4%) were females. 71.1% of the patients were of Gartland class II fractures and 28.9% were of Gartland class III. 43.4% had an injury due to fall while playing while 19.3% had fallen from height. 80.7% were found to have a satisfactory functional outcome.Conclusions: It was inferred that the functional outcome of pediatric displaced supracondylar humeral fractures is satisfactory when managed with percutaneous crossed K-wire fixation
Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprungâs disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprungâs disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36â39) and median bodyweight at presentation was 2·8 kg (2·3â3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
pâ€0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88â4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59â2·79], p<0·0001), sepsis at presentation (1·20
[1·04â1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4â5 vs ASA 1â2, 1·82 [1·40â2·35], p<0·0001; ASA 3 vs ASA 1â2, 1·58, [1·30â1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02â1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41â2·71], p=0·0001; parenteral nutrition 1·35, [1·05â1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47â0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50â0·86], p=0·0024) or percutaneous central line (0·69 [0·48â1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and lowâmiddle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of âsingle-useâ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for lowâmiddle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both highâ and lowâmiddleâincome countries
On Probabilistic Assessment of Exergy Analysis of a Wind Turbine for Optimum Performance
Judgment on the performance of a wind turbine depends upon its first law efficiency as well as its second law efficiency. This paper focuses on the second law efficiency, i.e., the exergy efficiency of a wind turbine. The work introduces a novel technique to determine the optimum performance conditions of a wind turbine. Jhimpir city, Pakistan, has been selected as a case study. The wind speed distribution of the selected area is analyzed using different probability density functions. Three-parameter Weibull Distribution turns out to be the best probability density function fitting the wind speed variation. Probability distribution of total wind exergy is performed, and a one-year variation of wind exergy is plotted, showing maximum exergy around the middle of the year. The exergy efficiency of the turbine using a power curve and wind exergy is determined at different wind speeds. Probabilities of various exergy efficiencies are also determined. Results show that higher exergy efficiency has a high probability but so does low exergy efficiency due to seasonal variations. The proposed method can be extended to any wind farm provided the geographical and meteorological parameters of the site.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

PakSurg 1: determining the epidemiology and risk factors of surgical site infections in Pakistanâa multicentre, prospective cohort study
Introduction Surgical site infections (SSIs) are among the the most common postoperative complications, despite being highly preventable. Multiple studies have explored the incidence and risk factors of SSIs globally. However, nationally representative data capable of informing evidence-based guidelines remain limited in Pakistan. Hence, the aim of this study is to identify the incidence and risk factors of developing SSIs following surgery and to explore existing SSI prevention practices in Pakistan.Methods and analysis This study is a multicentre, prospective cohort study across various sites in Pakistan. All consecutive adult patients undergoing inpatient elective surgery in a 1âmonth patient recruitment window from one or more of the nine eligible subspecialties will be included in the study. Patients with preoperative infections, emergency surgeries or intraoperative mortality are to be excluded. The following surgical subspecialties are included: breast surgery, cardiac surgery, colorectal surgery, cranial surgery, general surgery, obstetrics and gynaecology, orthopaedics surgery, spine surgery and vascular surgery. Each mini-team of up to three collaborators can select one of the nine subspecialties and a 1âmonth patient recruitment window from 20 September 2022 to 31 March 2023. Multiple mini-teams from the same sites can recruit patients across the same subspecialty in distinct patient recruitment windows. Additionally, multiple mini-teams from the same sites can recruit patients across different subspecialties in the same or distinct patient recruitment windows. The primary outcome is 30 day SSIs. Secondary outcomes include 30 day antibiotic-resistant SSIs, organ-space infections, other healthcare associated infections, reinterventions and all-cause mortality.Ethics and dissemination Approval was received by the Aga Khan University (AKU) Ethics Review Committee (ERC) and the National Bioethics Committee (NBC) Pakistan. The results from this study will be disseminated by the steering committee in journal publications, conference presentations and on other academic platforms. Evidence-based guidelines that result from these data will be disseminated to all surgical care providers in Pakistan through national networks

BJS commission on surgery and perioperative care post-COVID-19
Background: Coronavirus disease 2019 (COVID-19) was declared a pandemic by the WHO on 11 March 2020 and global surgical practice was compromised. This Commission aimed to document and reflect on the changes seen in the surgical environment during the pandemic, by reviewing colleagues experiences and published evidence. Methods: In late 2020, BJS contacted colleagues across the global surgical community and asked them to describe how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had affected their practice. In addition to this, the Commission undertook a literature review on the impact of COVID-19 on surgery and perioperative care. A thematic analysis was performed to identify the issues most frequently encountered by the correspondents, as well as the solutions and ideas suggested to address them. Results: BJS received communications for this Commission from leading clinicians and academics across a variety of surgical specialties in every inhabited continent. The responses from all over the world provided insights into multiple facets of surgical practice from a governmental level to individual clinical practice and training. Conclusion: The COVID-19 pandemic has uncovered a variety of problems in healthcare systems, including negative impacts on surgical practice. Global surgical multidisciplinary teams are working collaboratively to address research questions about the future of surgery in the post-COVID-19 era. The COVID-19 pandemic is severely damaging surgical training. The establishment of a multidisciplinary ethics committee should be encouraged at all surgical oncology centres. Innovative leadership and collaboration is vital in the post-COVID-19 era
