A Comparison of Post-Procedural Hemoglobin in Catheter-Directed Thrombolysis vs. Large-Bore Aspiration Thrombectomy for Acute Pulmonary Embolism.

PURPOSE: To compare changes in hemoglobin (HB) following catheter-directed thrombolysis (CDL) vs. large-bore aspiration thrombectomy (LBAT) of acute pulmonary embolism (PE). MATERIALS AND METHODS: Single-center retrospective review of acute high and intermediate-risk PE patients treated with CDL or LBAT between 12/2009 and 9/2023. The LBAT group was divided according to usage of an autotransfusion device (ATD). There were 166 patients in the CDL group (56±15 years). LBAT patients were treated without (LBAT, n=58, 61±16 years) or with an ATD (LBATw, n=47, 62±15 years). Endpoints included change in HB between pre- and post-procedure measurements, the 7-day postprocedural nadir (low point), and adverse events (AE). RESULTS: The mean HB change between pre- and post-procedure in the CDL, LBAT, and LBATw groups was -1.3±1.3 g/dl, -1.6±0.98 g/dl, and -1.1±0.9 g/dl, respectively (p=0.098). The mean HB change to the 7-day postprocedural nadir in the CDL, LBAT, and LBATw groups was -1.7±1.4 g/dl, -2.4±1.3 g/dl, and -1.8±1.3 g/dl, respectively (p=0.008). Minor hemorrhagic AE rate was 3.6% in CDL, 12.1% in LBAT, and 14.9% in LBATw (p=0.010). There was no significant difference in moderate (p=0.079) and major (p=0.529) hemorrhagic AE between the groups. There were no procedure related mortalities. CONCLUSION: Use of LBAT without ATD resulted in a significant decrease in HB to the 7-day post-procedural nadir when compared to CDL or LBAT with ATD. This did not translate into significantly higher transfusion rates, moderate or major hemorrhagic events. Findings suggest that the decision between CDL and LBAT should not be based solely on the expected blood loss consideration.

Prediction and expression analysis of deleterious nonsynonymous SNPs of Arabidopsis ACD11 gene by combining computational algorithms and molecular docking approach.

Accelerated cell death 11 (ACD11) is an autoimmune gene that suppresses pathogen infection in plants by preventing plant cells from becoming infected by any pathogen. This gene is widely known for growth inhibition, premature leaf chlorosis, and defense-related programmed cell death (PCD) in seedlings before flowering in Arabidopsis plant. Specific amino acid changes in the ACD11 protein's highly conserved domains are linked to autoimmune symptoms including constitutive defensive responses and necrosis without pathogen awareness. The molecular aspect of the aberrant activity of the ACD11 protein is difficult to ascertain. The purpose of our study was to find the most deleterious mutation position in the ACD11 protein and correlate them with their abnormal expression pattern. Using several computational methods, we discovered PCD vulnerable single nucleotide polymorphisms (SNPs) in ACD11. We analysed the RNA-Seq data, identified the detrimental nonsynonymous SNPs (nsSNP), built genetically mutated protein structures and used molecular docking to assess the impact of mutation. Our results demonstrated that the A15T and A39D mutations in the GLTP domain were likely to be extremely detrimental mutations that inhibit the expression of the ACD11 protein domain by destabilizing its composition, as well as disrupt its catalytic effectiveness. When compared to the A15T mutant, the A39D mutant was more likely to destabilize the protein structure. In conclusion, these mutants can aid in the better understanding of the vast pool of PCD susceptibilities connected to ACD11 gene GLTP domain activation.

Short- and mid-term outcomes of abdominoperineal resection with perineal mesh insertion: a single-centre experience.

PURPOSE: Abdominoperineal resection (APR) remains a key procedure for the treatment of low rectal/anorectal cancers. However, perineal wound closure remains challenging, particularly in extralevator abdominoperineal resection (ELAPR) due to gapped tissue planes. Different approaches have been attempted to improve perineal wound repair. The aim of this study is to report our 6-year experience in perineal wound closure utilising biological mesh. METHODS: We conducted a retrospective study using data from our prospectively maintained database, including patients who underwent APR with perineal mesh closure between 2016 and 2021. RESULTS: 49  patients underwent APR with perineal mesh reconstruction for low rectal cancer during the 6-year period. Of these, 63% were males, with a mean age of 68 (± 11), and a mean BMI of 27.9 (± 13.7). 49% (24) of patients received neoadjuvant therapy. 88% (43) of patients underwent standard "S-APR" and only 12% (6) underwent ELAPR. Majority of procedures were laparoscopic (87.8%) with conversion rate of 6.9%. Mean length of stay was 11.7 (± 11.6). The perineal wound infection rate was 30% and only two patient required mesh removal due to entero-cutaneous perineal fistula and pelvic abscess. Perineal hernia was found in only two patients (4.1%). CRM was negative in 81.6% of the patients. Mean follow-up period was 29.2 (± 16.5) months, and disease recurrence occurred in 9 (18.3%) patients with average number of months for recurrence of 21 (± 7). Overall survival during the follow-up period was 91%. CONCLUSION: Our series shows a favourable short- and medium-term outcome with routine insertion of mesh for perineal wound closure.

Serbian National Training Programme for minimally invasive colorectal surgery (LapSerb): short-term clinical outcomes of over 1400 colorectal resections.

INTRODUCTION: The Serbian National Training Programme for minimally invasive colorectal surgery (LapSerb) was introduced to implement laparoscopic colorectal surgery across Serbia. The programme aimed to accelerate training of established colorectal surgeons through a competency-based programme. This involved knowledge assessment, workshops, live operating, and competency-based assessment of unedited videos. The aim of this study is to report the outcomes of laparoscopic colorectal resection performed by LapSerb certified surgeons. METHODS: LapSerb prospectively maintained multicentred database was analysed for laparoscopic colorectal resections from January 2015 to February 2021. Data collected included patient demographics, indications for surgery, perioperative data, and 30-day outcomes. RESULTS: A total of 1456 laparoscopic colectomies by 24 certified surgeons were included in the final analysis. Mean age was 67 (± 12) years old and male to female ratio was 1:1.5. 83.1% of the colectomies were malignant, mainly due to adenocarcinoma. Anterior resection was the most common procedure with 699 (48%) cases, followed by right and left colectomies with 357 (24.5%) and 303 (21%) procedure respectively. 4.8% of patients required conversion to open surgery. Thirty-day readmission and reoperation rates were 2.3% and 4.7%, respectively. Overall mortality in all cases was 1.1% and R0 resections were achieved in 97.8% of malignant colectomies. CONCLUSION: The LapSerb programme successfully and safely established laparoscopic colorectal surgery across the country with comparable and acceptable short-term clinical outcomes.

Barriers experienced by community midwives to provide basic emergency obstetric and newborn care in rural Pakistan.

BACKGROUND: Considering the high maternal mortality rate, the government of Pakistan has deployed Community Midwives (CMWs) in rural areas of Pakistan. This relatively new cadre of community-based skilled birth attendants has previously reported to experience several challenges in providing maternal and child healthcare. However, what barriers they experience in providing basic emergency obstetric and newborn care needs to be further studied. METHODS: This was a cross-sectional study conducted in twelve districts in Sindh province, Pakistan, with poor maternal and child health indicators. A total of 258 CMWs participated in this study and completed the questionnaire on a pretested, validated tool in their community-based stations. The trained data collectors completed the questionnaires from the respondents. The problems identified were categorized into three major issues: financial, and transport and security related; and were analyzed accordingly. Ethical approval was obtained from the institutional review board (IRB) of Health Services Academy (HSA) Islamabad, Pakistan. RESULTS: The majority (90%) of 258 CMWs had formal training in maternal and neonatal care from the recognized institutions. Financial difficulties faced by CMWs were identified as the most frequent barriers and others were transport, security, and other issues. In univariate analysis, 38.1% and 61.9% of the community midwives who faced financial difficulties had completed a graduation or intermediate level of education, respectively (p = 0.006). Round-the-clock availability for emergencies was inversely associated with having financial difficulties, i.e., 71.4%, in contrast to 28.4% who had financial difficulties were available round-the-clock for emergency calls in their community clinics (p = 0.008). Formal training (p = 0.001), work experience (p = 0.015), longer duration of work (p = 0.003), and liaison with health workers and posting district (p = 0.001) had statistically significantly higher transport related issues. Security difficulties faced by CMWs and a set of correlates such as formal training (p = 0.019), working experience (p = 0.001), longer duration of work (p = 0.023), 24 h of availability on call (p = 0.004), liaison with traditional birth attendants (TBAs) in the community (p = 0.002), and district of posting (p = 0.001) were statistically significantly different. Other issues like working experience (p = < 0.001) and Liaison with TBAs in the community (p = < 0.001) were found statistically significant. CONCLUSION: Financial, transportation and security related barriers were commonly reported by community midwives in the delivery of basic emergency obstetric and newborn care in rural Pakistan.

Sequential evolution of virulence and resistance during clonal spread of community-acquired methicillin-resistant Staphylococcus aureus.

The past two decades have witnessed an alarming expansion of staphylococcal disease caused by community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA). The factors underlying the epidemic expansion of CA-MRSA lineages such as USA300, the predominant CA-MRSA clone in the United States, are largely unknown. Previously described virulence and antimicrobial resistance genes that promote the dissemination of CA-MRSA are carried by mobile genetic elements, including phages and plasmids. Here, we used high-resolution genomics and experimental infections to characterize the evolution of a USA300 variant plaguing a patient population at increased risk of infection to understand the mechanisms underlying the emergence of genetic elements that facilitate clonal spread of the pathogen. Genetic analyses provided conclusive evidence that fitness (manifest as emergence of a dominant clone) changed coincidently with the stepwise emergence of (i) a unique prophage and mutation of the regulator of the pyrimidine nucleotide biosynthetic operon that promoted abscess formation and colonization, respectively, thereby priming the clone for success; and (ii) a unique plasmid that conferred resistance to two topical microbiocides, mupirocin and chlorhexidine, frequently used for decolonization and infection prevention. The resistance plasmid evolved through successive incorporation of DNA elements from non-S. aureus spp. into an indigenous cryptic plasmid, suggesting a mechanism for interspecies genetic exchange that promotes antimicrobial resistance. Collectively, the data suggest that clonal spread in a vulnerable population resulted from extensive clinical intervention and intense selection pressure toward a pathogen lifestyle that involved the evolution of consequential mutations and mobile genetic elements.

Predictors of knowledge and use of long-lasting insecticidal nets for the prevention of malaria among the pregnant women in Pakistan.

BACKGROUND: Malaria is endemic to Pakistan with high prevalence among pregnant women and linked with maternal anaemia, intrauterine growth retardation, preterm birth, and low birth weight. The use of long-lasting insecticidal nets (LLINs) is a proven and cost-effective intervention preventing malaria among pregnant women. The present study aimed to explore predictors of knowledge and use of LLINs among pregnant women in Pakistan. METHODS: This was part of a quasi-experimental study of 200 pregnant women conducted in a rural district of Sindh province in Pakistan. Data were collected using Malaria Indicator Survey questionnaires developed by Roll Back Malaria Partnership to end Malaria Monitoring and Evaluation Reference Group. Pregnant women and mothers with newborns of six months of age were interviewed in their homes. RESULTS: The age of the women was from 18 to 45, two thirds of the respondents (72.5%) were uneducated and married (77%). Majority (92%) of the women had received antenatal care during pregnancy, and 29.5% women had received counseling on malaria during their antenatal care visits. Multiple linear regression showed that the type of latrine was the most significant (ß = 0.285, p < 0.001) determinant of knowledge about malaria among pregnant women followed by the death of a newborn (ß = 0.271, p < 0.001). The use of mobile phone was the most significant (ß = 0.247, p < 0.001) predictor of usage of LLINs among pregnant women followed by the death of a newborn (ß = 0.232, p < 0.05). CONCLUSIONS: Maternal education, type of latrine, use of mobile phone, malaria during previous pregnancy and newborn death were strong predictors of knowledge and use of LLINs in pregnant women in Pakistan. There is a need to scale-up programmes that aim to create awareness regarding malaria among pregnant women. Mobile phone technology can be used to implement awareness programmes focusing on malaria prevention among women.

A stepwise approach to laparoscopic right hemicolectomy with D2 excision. An illustrated video guide for training colorectal surgeons - a video vignette.

We present a stepwise approach to performing a laparoscopic right hemicolectomy along with D2 excision. The video illustrates a modular approach for set up and resection, performed on a 60-year-old male patient, with a cancer in the ascending colon. The procedure is divided into its key steps, which include patient position, port placement and anatomical exposure, medial to lateral dissection with vessel control, sub-ileal dissection, lateral mobilization, hepatic flexure mobilization and extraction with extracorporeal anastomosis. The key regional anatomy is highlighted alongside diagrams illustrating standard anatomy and common anatomical variants. We believe this video provides a valuable resource for trainee surgeons to expand their understanding regarding steps of the procedure and associated anatomy.

An analysis of the impact of newborn survival policies in Pakistan using a policy triangle framework.

INTRODUCTION: Pakistan has made slow progress towards reducing the newborn mortality burden; as a result, it has the highest burden of newborn mortality worldwide. This article presents an analysis of the current policies, plans, and strategies aimed at reducing the burden of newborn death in Pakistan for the purpose of identifying current policy gaps and contextual barriers towards proposing policy solutions for improved newborn health. METHODS: We begin with a content analysis of federal-level policies that address newborn mortality within the context of health system decentralization over the last 20 years. This is then followed by a case study analysis of policy and programme responses in a predominantly rural province of Pakistan, again within the context of broader health system decentralization. Finally, we review successful policies in comparable countries to identify feasible and effective policy choices that hold promise for implementation in Pakistan, considering the policy constraints we have identified. RESULTS: The major health policies aimed at reduction of newborn mortality, following Pakistan's endorsement of global newborn survival goals and targets, lacked time-bound targets. We found confusion around roles and responsibilities of institutions in the implementation process and accountability for the outcomes, which was exacerbated by an incomplete decentralization of healthcare policy-making and health service delivery, particularly for women around birth, and newborns. Such wide gaps in the areas of target-setting, implementation mechanism, and evaluation could be because the policy-making largely ignored international commitments and lessons of successful policy-making in comparable regional counties. CONCLUSIONS: Inclusion of clear goals and targets in newborn survival policies and plans, completion of the decentralization process of maternal and child healthcare service delivery, and policy-making and implementation by translating complex evidence and using regional but locally applicable case studies will be essential to any effective policy-making on newborn survival in Pakistan.

Heavy metals drinking water contamination and health risk assessment among primary school children of Pakistan.

The purpose of this study was to characterize the concentrations of lead (Pb), cadmium (Cd), manganese (Mn), and Fe (Fe) in drinking water sources in primary schools in Sindh Province, Pakistan and to quantify potential health risks among those school children. We conducted a representative, cross-sectional study among 425 primary schools in Sindh province of Pakistan. We used risk assessment models to estimate the metal index, pollution index, lifetime cancer risk, and hazard quotient index. Across the 425 sampled schools, the levels of heavy metals in the drinking water often exceeded the WHO permissible limits (67% of schools exceeded Pb limit, 17% for Cd, 15% for Fe). The average incremental lifetime cancer risk (ILCR) for Pb exceeded tolerable limits in all of the districts under study. The findings, particularly for Pb, are of concern, as Pb may negatively influence children's growth, development, school performance, and long-term health.

Surface charge dominated protein absorption on hydrogels.

Soft tissue engineering requires antifouling materials that are biocompatible and mechanically flexible. Conventional hydrogels containing more than 70 wt% water are thus promising antifouling material candidates. However, some hydrogels are difficult to apply in internal body organs because of undesirable protein absorption on their surfaces. Due to the lack of an effective method for observing the true charge densities of hydrogels, the reason why electrostatic interactions dominate protein absorption behavior remains unclear. In this work, we adopt the microelectrode technique (MET) to study the electrical potentials of hydrogels with negative, positive, and neutral potentials and demonstrate the protein absorption behaviors on those hydrogels. The results show that MET is an effective method to obtain the surface charge densities of various hydrogels. Furthermore, the amounts of absorbed proteins on the gels were quantified with respect to the charge densities of the hydrogels. The results indicate that electrostatic absorption is quantitatively dominated by a combination of hydrogel charge density and overall protein charge. Based on the knowledge obtained in this work, the effects of hydrogel surface charges on protein absorption can be better understood. Thus, the results are expected to promote the application of hydrogels in tissue engineering.

Availability of emergency obstetric and newborn care services at public health facilities of Sindh province in Pakistan.

BACKGROUND: Basic and comprehensive emergency obstetric care services in Pakistan remain a challenge considering continued high burden of maternal and newborn mortality. This study aimed to assess the availability of emergency obstetric and newborn care in Sindh Province of Pakistan. METHODS: This cross-sectional survey was conducted in twelve districts of the Sindh province in Pakistan. The districts were selected based on the maternal neonatal and child health indicators. Data were collected from 63 public-sector health facilities including district, Taluka (subdistrict) headquarters hospitals and rural health centers. Basic and comprehensive emergency obstetric newborn care services were assessed through direct observations and interviews with the heads of the health facilities by using a World Health Organization pretested and validated data collection tool. Participants interviewed in this study included the managers and auxiliary staff and in health facilities. RESULTS: Availability of caesarean section (23, 95% C.I. 14.0-35.0) and blood transfusion services (57, 95% CI. 44.0-68.0), the two components of comprehensive emergency obstetric and newborn care, was poor in our study. However, assessment of the seven components of basic emergency obstetric and newborn services showed that 92% of the health facilities (95% C.I. 88.0-96.0) had parenteral antibiotics, 90%, (95% C.I. 80.0-95.0) had oxytocin, 92% (95% CI 88.0-96.0) had manual removal of the placenta service, 87% (95%, C.I. 76.0-93.0) of the facilities had staff who could remove retained products of conception, 82% (95% C.I. 71.0-89.0) had facilities for normal birth and 80% (95% C.I. 69.0-88.0) reported presence of neonatal resuscitation service. CONCLUSION: Though the basic obstetric and newborn services were reasonably available, comprehensive obstetric and newborn services were not available as per the World Health Organization's standards in the surveyed public health facilities. Ensuring the availability of caesarean section and blood transfusion services within these facilities may improve population's access to these essential services around birth.

Association of Overweight and Obesity with High Fast Food Consumption by Gulf Cooperation Council Medical Students.

Fast food and sugar-sweetened soft drink consumption, adiposity, and physical activity behavior were determined through a cross-sectional study with 251 medical students from the Gulf Cooperation Council countries. Approximately 38% of the students were overweight or obese, and 56.2% consumed fast food in the past 24 h. Main reasons for consuming fast foods were lack of time to cook healthy food (51%), pleasant taste (26%) and the influence of family and friends (15%). Overweight status or obesity was more prevalent among males (50%), those having greater knowledge about calories in fast-food meals (51.6%), who checked fast food calories before eating (47.7%) or overestimated the amount of sugar in a soft drink (17.82 ± 26.59 spoons). Overweight or obese participants also performed more moderate physical activity (1.73 ± 2.08 days per week) compared to those with normal weight or underweight (p = <0.05). Fast food consumption can be curtailed by improving the availability of and access to healthier foods and implementing behavior change and regulatory interventions.

Implementation of robotic rectal surgery training programme: importance of standardisation and structured training.

PURPOSE: A structured training programme is essential for the safe adoption of robotic rectal cancer surgery. The aim of this study is to describe the training pathway and short-term surgical outcomes of three surgeons in two centres (UK and Portugal) undertaking single-docking robotic rectal surgery with the da Vinci Xi and integrated table motion (ITM). METHODS: Prospectively, collected data for consecutive patients who underwent robotic rectal cancer resections with the da Vinci Xi and ITM between November 2015 and September 2017 was analysed. The short-term surgical outcomes of the first ten cases of each surgeon (supervised) were compared with the subsequent cases (independent). In addition, the Global Assessment Score (GAS) forms from the supervised cases were analysed and the GAS cumulative sum (CUSUM) charts constructed to investigate the training pathway of the participating surgeons. RESULTS: Data from 82 patients was analysed. There were no conversions to open, no anastomotic leaks and no 30-day mortality. Mean operation time was 288 min (SD 63), median estimated blood loss 20 (IQR 20-20) ml and median length of stay 5 (IQR 4-8) days. Thirty-day readmission and reoperation rates were 4% (n = 3) and 6% (n = 5) respectively. When comparing the supervised cases with the subsequent solo cases, there were no statistically significant changes in any of the short-term outcomes with the exception of mean operative time, which was significantly shorter in the independent cases (311 vs 275 min, p = 0.038). GAS form analysis and GAS CUSUM charting revealed that ten proctoring cases were enough for trainee surgeons to independently perform robotic rectal resections with the da Vinci Xi. CONCLUSIONS: Our results show that by applying a structured training pathway and standardising the surgical technique, the single-docking procedure with the da Vinci Xi is a valid, reproducible technique that offers good short-term outcomes in our study population.

Smoking behavior of males attending the quit tobacco clinics in Bahrain and their knowledge on tobacco smoking health hazards.

BACKGROUND: One third of Bahraini adult (20-64 years) males and 7.0% of females use some form of tobacco. The corresponding rates for cigarette and waterpipe tobacco smoking (WTS) are 11.0% and 6.0%, respectively. The objective of the study was to determine the knowledge on tobacco smoking and past smoking related behavior of male patients attending the Quit Tobacco Clinics (QTC) in Bahrain. METHODS: A sample of 339 male clinic attendees was taken proportional to the population distribution in the three QTC at Al Hoora Health Center, Hamad Kanoo Health Center, and Bank of Bahrain and Kuwait Health Center. Data collection was performed until the sample size was completed (September 2015 to December 2016). Knowledge on the health effects of cigarette and WTS was examined based on 10 statements on cigarette and similar ones on WTS. Respondents "agreeing" with the statements were considered knowledgeable and those "disagreeing" or responding "don't know", not knowledgeable. All the "agree" responses for cigarette/WTS were summed across the 10 health effects and average health knowledge scores for cigarette/WTS were computed. RESULTS: Most of the study participants were Bahraini nationals, ever married and educated with at least secondary level. The majority (65.8%) of participants smoked a single type of tobacco product, and the rest, two (28.0%) or three or more (6.2%). Age of starting cigarette and WTS was 16.2 ± 4.0 and 19.3 ± 6.7 years, respectively. The majority (81%) smoked in the presence of other family members and 26.3% in the presence of a child. 76.2% smoked in the presence of others in their cars. 18.9% of the attendees had quit smoking at the time of interview. 81% of the participants knew about the hazards of both cigarette and WTS with a significantly higher (p = 0.0001) mean knowledge score for cigarette (93.3 ± 3.0%) than WTS (85.2 ± 2.1%). CONCLUSION: The relative lack of knowledge on the hazards of WTS in a sample of Arab country population with an increasing trend of WTS warrants the attention of health policy makers in the country and region.

Knowledge of health professional students on waterpipe tobacco smoking: curricula implications.

BACKGROUND: Tobacco prevention research traditionally focuses upon cigarette smoking, but there is also a need to implement and evaluate the usefulness of waterpipe tobacco smoking (WTS) interventions since it is considered less harmful than cigarettes. This study aimed to assess the impact of an educational intervention on WTS knowledge of health professional students in three academic health institutions in Bahrain. METHODS: A quasi-experimental design was used to include medical students from the Arabian Gulf University, medical and nursing students from the Royal College of Surgeons in Ireland-Bahrain and nursing students from the University of Bahrain. Two hundred fifty students participated in the three phases of the study during October 2015-June 2016 from an original sample of 335. The participants answered knowledge questions on WTS before and after an intervention, which included a lecture by an expert and a video on the awareness about the health hazards of WTS. RESULTS: The mean age of starting cigarette and WTS was 16.8 ± 2.8 and 17.5 ± 1.7 years, respectively. The prevalence of ever smoking any type of tobacco among students was 22.4% (medical 25.8% and nursing 37.5%) and that of WTS, 17.7% (medical 20.0%, nursing 13.6%). The prevalence of current cigarette smoking was 9.6% among medical and nursing students combined with 10.3 and 8.5% for medical and nursing students, respectively. WTS was prevalent at a proportion of 6.8% among medical and nursing students combined with 6.5% in medical and 14.8% in nursing students. The university curriculum as the main source of knowledge on WTS increased from 14.2 to 33.3% after the intervention (p < 0.005). Knowledge about the hazards of WTS increased in 16 of the 20 statements. The difference in overall knowledge score was significant (p < 0.05) for nursing (77. 5 ± 1.5 vs 85.8 ± 2.2) compared to medical students (85.3 ± 1.0 vs 87.3 ± 0.9) after the intervention. CONCLUSIONS: Our educational intervention with health professional students improved their knowledge about the health effects of WTS. Medical and nursing institutions may consider using various methods such as informative videos and expert lectures to include in their teaching curricula as part of WTS prevention strategies.

Urogenital function in robotic vs laparoscopic rectal cancer surgery: a comparative study.

PURPOSE: Urological and sexual dysfunction are recognised risks of rectal cancer surgery; however, there is limited evidence regarding urogenital function comparing robotic to laparoscopic techniques. The aim of this study was to assess the urogenital functional outcomes of patients undergoing laparoscopic and robotic rectal cancer surgery. METHODS: Urological and sexual functions were assessed using gender-specific validated standardised questionnaires. Questionnaires were sent a minimum of 6 months after surgery, and patients were asked to report their urogenital function pre- and post-operatively, allowing changes in urogenital function to be identified. Questionnaires were sent to 158 patients (89 laparoscopy, 69 robotic) of whom 126 (80 %) responded. Seventy-eight (49 male, 29 female) of the responders underwent laparoscopic and 48 (35 male, 13 female) robotic surgery. RESULTS: Male patients in the robotic group deteriorated less across all components of sexual function and in five components of urological function. Composite male urological and sexual function score changes from baseline were better in the robotic cohort (p < 0.001). In females, there was no difference between the two groups in any of the components of urological or sexual function. However, composite female urological function score change from baseline was better in the robotic group (p = 0.003). CONCLUSION: Robotic rectal cancer surgery might offer better post-operative urological and sexual outcomes compared to laparoscopic surgery in male patients and better urological outcomes in females. Larger scale, prospective randomised control studies including urodynamic assessment of urogenital function are required to validate these results.

Prior experience in laparoscopic rectal surgery can minimise the learning curve for robotic rectal resections: a cumulative sum analysis.

BACKGROUND: The learning curve for robotic colorectal surgery is ill-defined. This study aimed to investigate the learning curve of experienced laparoscopic rectal surgeons when starting with robotic total mesorectal excision (TME) using cumulative sum (CUSUM) charts. METHODS: This retrospective case series analysed patients who underwent curative and elective laparoscopic or robotic TMEs for rectal cancer performed by two surgeons. The first consecutive robotic TME cases of each surgeon were 1:1 propensity score matched to their laparoscopic TME cases using age, body mass index, American Society of Anesthesiologists grade, T stage (AJCC) and tumour location height. The matched laparoscopic cases defined individual standards for the quality indicators: operating time, R stage, lymph node harvest, length of hospital stay and major complications (Clavien-Dindo grade 3-5). Deviation of more than a quarter of a standard deviation from the mean for the continuous indicators, or exceeding the observed risk for the binary indicators was defined as off-target with an upward inflection in the CUSUM curve. RESULTS: From 2006 to 2015, 384 (294 laparoscopic; 90 robotic) TMEs met the inclusion criteria. Surgeon A performed 206 (70.1%) of the laparoscopic and 43 (47.8%) of the robotic cases. Surgeon B performed 88 (29.9%) of the laparoscopic and 47 (52.2%) of the robotic cases. After matching, no covariate exhibited an absolute standardised mean difference >0.25. For surgeon A, the CUSUM curves showed no apparent learning process compared to his laparoscopic standards. For surgeon B, a learning process for operation time, lymph node harvest and major complications was demonstrated by an initial upward inflection of the CUSUM curves; after 15 cases, all quality indicators were generally on target. CONCLUSIONS: For experienced laparoscopic colorectal surgeons, the formal learning process for robotic TME may be short to reach a similar performance level as obtained in conventional laparoscopy.

Status of cold chain in routine immunisation centres of the Expanded Programme on Immunisation in Quetta, Pakistan.

OBJECTIVE: To determine the status of cold chain and knowledge and practices of health workers about cold chain maintenance in routine immunisation health centres. METHODS: This cross-sectional study was conducted in Quetta, Pakistan, from May to July 2012, and comprised health facilities in the district. We interviewed the staff responsible for vaccine storage and cold chain maintenance and used a checklist to assess cold chain maintenance of routine expanded programme on immunisation vaccines. SPSS 16 was used for data analysis.. RESULTS: Of the 42 health facilities, staff of 13(30%) wrongly indicated that measles and Bacillus Calmette-Guérin were cold sensitive vaccines. Temperature of the ice-lined refrigerators was not maintained twice daily in 18(43%) centres. There were no voltage stabilisers and standby power generators in 31(74%) and 38(90%) centres, respectively. Vaccine arrangement was found to be inappropriate in ice-lined refrigerators of 38(90%) centres and ice packs were incorrectly used in carriers in 22(52%) centres. Vaccine stock was not charted in 39(93%) centres. Moreover, 4(10%) facilities did not have dedicated expanded programme on immunisation rooms whereas about 5(12%) and 33(79%) had no vaccinator and separate expanded programme on immunisation incharge appointed. Also, 32(76%) centres did not have a female vaccinator appointed. CONCLUSIONS: Although the majority of health staff had adequate knowledge, there were weaknesses in practice of maintaining the cold chain.
