Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study
Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.
Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.
Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001).
Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication
Knowledge, attitudes, and practices of Iraqi parents regarding antibiotic use in children and the implications
Background: Antibiotic misuse is a major global health issue, particularly in low- and middle-income countries (LMICs), where inappropriate use contributes to antimicrobial resistance (AMR). Inappropriate antibiotic use is exacerbated in LMICs by pressure from parents on physicians and pharmacists to prescribe and dispense antibiotics for their children often for viral infections. There is currently limited knowledge of key issues in Iraq to improve future antibiotic use. Consequently, we explored knowledge, attitudes, and practices (KAP) of Iraqi parents regarding antibiotic use in their children to provide future direction. Methods: A cross-sectional survey was conducted between November 2023-September 2024 among 1,878 parents in four districts of Iraq. A structured questionnaire assessed parents' KAP towards antibiotic-related uses and practices. Data were analyzed using descriptive statistics and Chi-square tests to examine associations between demographic variables and KAP indicators. Results: Among the participants, 83% were aware that antibiotics are ineffective for viral infections, and 75% recognized potential side-effects from antibiotics. Despite this knowledge, 63% of parents admitted to ad-ministering antibiotics to their children without a prescription, with 42% discontinuing treatment once symptoms improved. Factors including cost, dosage, and taste influenced antibiotic selection. Parents with higher education and income levels were more likely to engage in self-medication. Pharmacists were the primary source of antibiotic information for 52% of respondents. Conclusions: Despite adequate knowledge, inappropriate practices such as self-medication and discontinuing treatment early were prevalent. Targeted educational campaigns, particularly among parents with higher education levels and incomes, are necessary to mitigate AMR in Iraq
Use of Telemedicine for Postdischarge Assessment of the Surgical Wound: International Cohort Study, and Systematic Review With Meta-analysis
Objective:
This study aimed to determine whether remote wound reviews using telemedicine can be safely upscaled, and if standardized assessment tools are needed.
//
Background:
Surgical site infection (SSI) is the most common complication of surgery worldwide, and frequently occurs after hospital discharge. Evidence to support implementation of telemedicine during postoperative recovery will be an essential component of pandemic recovery.
//
Methods:
The primary outcome of this study was SSI reported up to 30 days after surgery (SSI), comparing rates reported using telemedicine (telephone and/or video assessment) to those with in-person review. The first part of this study analyzed primary data from an international cohort study of adult patients undergoing abdominal surgery who were discharged from hospital before 30 days after surgery. The second part combined this data with the results of a systematic review to perform a meta-analysis of all available data conducted in accordance with PRIMSA guidelines (PROSPERO:192596).
//
Results:
The cohort study included 15,358 patients from 66 countries (8069 high, 4448 middle, 1744 low income). Of these, 6907 (45.0%) were followed up using telemedicine. The SSI rate reported using telemedicine was slightly lower than with in-person follow-up (13.4% vs 11.1%, P<0.001), which persisted after risk adjustment in a mixed-effects model (adjusted odds ratio: 0.73, 95% confidence interval: 0.63–0.84, P<0.001). This association was consistent across sensitivity and subgroup analyses, including a propensity-score matched model. In 9 eligible nonrandomized studies identified, a pooled mean of 64% of patients underwent telemedicine follow-up. Upon meta-analysis, the SSI rate reported was lower with telemedicine (odds ratio: 0.67, 0.47–0.94) than in-person (reference) follow-up (I2=0.45, P=0.12), although there a high risk of bias in included studies.
//
Conclusions:
Use of telemedicine to assess the surgical wound postdischarge is feasible, but risks underreporting of SSI. Standardized tools for remote assessment of SSI must be evaluated and adopted as telemedicine is upscaled globally
Antiviral Activity of κ-carrageenan Gel on Herpes Simplex Type І, a Human Study: An Open-Label Clinical Trial
Theoretical derivation for reaction rate constants of H abstraction from thiophenol by the H/O radical pool
Reaction and activation energy barriers are calculated for the H abstraction reactions (C 6H 5SH+X →C 6H 5S+XH, X=H, OH and HO 2) at the BB1K/GTLarge level of theory. The corresponding reactions with H 2S and CH 3SH are also investigated using the G3B3 and CBS-QB3 methods in order to demonstrate the accuracy of BB1K functional in finding activation barriers for hydrogen atom transfer reactions. Arrhenius parameters for the title reactions are fitted in the temperature range of 300K-2000K. The calculated reaction enthalpies are in good agreement with their corresponding experimental reaction enthalpies. It is found that H abstraction by OH radicals from the thiophenol molecule proceed in a much slower rate in reference to the analogous phenol molecule. ΔfH298o of thiophenoxy radical is calculated to be 63.3kcal/mol. Kinetic parameters presented herein should be useful in describing the decomposition rate of thiophenol; i.e., one of the major aromatic sulfur carriers, at high temperatures
A Rare Case of Intra-articular Osteochondroma of the Femoral Neck: A Case Report
Abstract
Introduction: The osteochondroma (OC) is considered a benign tumor with long bone preference. It presents usually at the metaphyseal part of the bone, with rare cases of intra-articular origins especially in the hip joint. The presentation of such rare cases varies according to its site and mass effect, which may compress the adjacent nerves, tendon, or vascular structures. The femoral neck OC carries a higher risk of femoral head vascular injury and necrosis, as well as sciatic nerve injury, which requires careful preoperative planning and intraoperative cautions. We report a rare case of intra-articular OC in the hip.
Case Report: A 28-year-old male, presented to our hospital, with complaints of right-side gluteal pain, decrease hip joint extension, and feeling of a hard mass for 2 years. The radiographic evaluation showed an osseous mass related posterior and inferior to the right femur neck, with cortical and medullary continuation, and cartilaginous cap on the magnetic resonance image. The suspicious was OC, and planned for excision and histopathological evaluation. The excision was done through lateral hip approach, and it was intra-articular with marked stretching of the joint capsule. Complete excision was done, as close as possible to the femoral neck cortex using saw and osteotomes, followed by prophylactic fixation using two cannulated screws. The histopathology reports confirm the diagnoses, and the patient started on hip range of motion and abductor strengthening exercises. Over a 4-month follow-up period the patient showed significant improvement in his hip range of motion.
Conclusion: The intra articular OC of the hip is as rare presentation of the OC, which carries the risks of avascular necrosis as well as nerve compression. Clinical suspicion, proper planning, and histopathological evaluation are needed for better results.
Keywords: Hip joint, intra-articular tumor, osteochondroma.</jats:p
Activated protein C resistance impact on Syrian candidates for in vitro fertilisation and the benefit of anticoagulation therapy: a retrospective cohort study
Activated protein C resistance (APCR) is a common thrombophilia, caused mainly by a mutation. The impact of APCR on the efficacy of In Vitro Fertilization (IVF) are still unclear, and no solid recommendations for its management were published. To investigate the effect of APCR on IVF outcomes and assess the efficacy of our management protocol, we retrospectively scanned the medical records of women who were tested with APCR assay in 2019 at our fertility centre. The 66 women (12%) positive for APCR had lower odds of reaching clinical pregnancies after IVF 0.18 [95% CI: 0.07–0.47] and fewer live births. The administration of low-molecular-weight heparin and aspirin associated with more implantation in treated compared to untreated APCR-positive women with an odds ratio of 43.2 [7.51–248.6]. In conclusion, APCR negatively affects the number of clinical pregnancies after IVF, but anticoagulation therapy can mitigate this effect and significantly increase clinical pregnancies.Impact StatementWhat is already known on this subject? The evidence about the impact of APCR on IVF outcomes is still inconclusive. According to the Canadian guideline, routine screening for thrombophilia in patients with recurrent pregnancy loss is not recommended. No clear recommendations regarding the management of APCR in the planning for IVF are yet available.What do the results of this study add? APCR significantly increases implantation failure among infertile women who conduct IVF. Management of APCR using LMWH and aspirin was effective in mitigating this effect and increasing successful implantation.What are the implications of these findings for clinical practice and/or further research? Our findings can support the recommendation to include APCR assay in the routine tests for infertile women conducting IVF, and suggest the combination between LMWH and aspirin as an effective therapy to increase successful implantation in APCR positive candidates. However, more controlled clinical trials are still needed to confirm our results. What is already known on this subject? The evidence about the impact of APCR on IVF outcomes is still inconclusive.

Synchronicity and peer-reviewed assignments in online scientific writing training with limited resources: a four-arm blinded randomized controlled trial with one-year follow-up
Abstract
Introduction:Syrian medical research synthesis is marginal compared to neighboring countries and faces numerous obstacles that have been intensified by the Syrian armed conflict. Perceived research barriers include the lack of mentorship and academic writing skills. We evaluate the outcomes of a peer-run academic writing and publishing workshop, and contrast training synchronicity and its supplementary peer-reviewed assignments. Methods:This randomized controlled trial studied an online workshop that targeted under- and post-graduate medical and paramedical students at all Syrian universities. Blinded participants were randomized into four arms; Two arms attended the workshop synchronously, and the others asynchronously. One arm in each group undertook peer-reviewed scientific writing exercises (active), while the other two self-reviewed the same exercises (passive). Objective knowledge and subjective confidence in the learnt skills were assessed before the workshop, and one month and one year after it.Results: One-hundred-twenty-one participants completed the workshop, which was effective in improving their knowledge (P<0.001) and confidence (P<0.001). The post-course measures of the synchronous and asynchronous groups were similar. Completing the assignments resulted in higher knowledge (P=0.005) and confidence (P=0.003) only in the active groups. Moreover, participants who joined the peer-review process gained higher knowledge (P<0.001). At one-year-follow-up, the participants showed stability of the objective and subjective gains.Conclusion:The investigated training was beneficial regardless of the methods of attendance (i.e., synchronicity). Participation in supplementary exercises, especially when associated with peer-review, improved knowledge and confidence. This workshop proves a utilizable effective cheap alternative to improve scientific writing skills with limited resources and expertise.</jats:p
Surgical site infection after gastrointestinal surgery in children : an international, multicentre, prospective cohort study
Introduction Surgical site infection (SSI) is one of the most common healthcare-associated infections (HAIs). However, there is a lack of data available about SSI in children worldwide, especially from low-income and middle-income countries. This study aimed to estimate the incidence of SSI in children and associations between SSI and morbidity across human development settings. Methods A multicentre, international, prospective, validated cohort study of children aged under 16 years undergoing clean-contaminated, contaminated or dirty gastrointestinal surgery. Any hospital in the world providing paediatric surgery was eligible to contribute data between January and July 2016. The primary outcome was the incidence of SSI by 30 days. Relationships between explanatory variables and SSI were examined using multilevel logistic regression. Countries were stratified into high development, middle development and low development groups using the United Nations Human Development Index (HDI). Results Of 1159 children across 181 hospitals in 51 countries, 523 (45 center dot 1%) children were from high HDI, 397 (34 center dot 2%) from middle HDI and 239 (20 center dot 6%) from low HDI countries. The 30-day SSI rate was 6.3% (33/523) in high HDI, 12 center dot 8% (51/397) in middle HDI and 24 center dot 7% (59/239) in low HDI countries. SSI was associated with higher incidence of 30-day mortality, intervention, organ-space infection and other HAIs, with the highest rates seen in low HDI countries. Median length of stay in patients who had an SSI was longer (7.0 days), compared with 3.0 days in patients who did not have an SSI. Use of laparoscopy was associated with significantly lower SSI rates, even after accounting for HDI. Conclusion The odds of SSI in children is nearly four times greater in low HDI compared with high HDI countries. Policies to reduce SSI should be prioritised as part of the wider global agenda.Peer reviewe
