Overuse of Intravenous Proton Pump Inhibitors in General Medicine and Surgery Wards.

BACKGROUND: Overuse of stress ulcer prophylaxis is prevalent globally despite guidelines leading to the added cost, especially the intravenous proton pump inhibitor (IVPPI). This study aims to analyze the prevalence of such overuse and be aware of rational use which may help develop local guidelines. METHODS: This study analyzed the prospectively collected data on IVPPI use in adult patients in general wards of medicine and surgery at Patan Hospital, Patan Academy of Health Sciences, Nepal, from April-Jun 2022. Ethical approval was obtained. Variables analyzed were the patient's age, gender, history of peptic ulcer disease, risk for stress ulcer and gastrointestinal bleeding, the status of nil per os (NPO ≥12 hours), appropriate use of IVPPI, and cost. RESULTS: Prevalence of IVPPI use was 36.24% (274/756 admissions), surgery 39.45(189/479), medicine ward 30.68% (85/277). The mean age was 43.1 ±18.6 years, males 113(41.2%), surgery 189 (69%). Inappropriate overuse in 253(92.3%, significantly more in surgery-182 than medicine-7, p=0.001. Appropriate use was in 21 (7.7%, i.e., NPO-15, NPO + gastrointestinal bleed, and NPO + non steroid anti-inflammatory drugs each 3). CONCLUSIONS: Prevalence of IVPPI use was 36.24%. Inappropriate overuse of IVPPI was high (92.2%, 253/274), more in surgery. The nil per os status was the main reason for appropriate use of IVPPI.

Guide, Co-guide, Supervisors as Author in Publication on Student Thesis.

Good research writing and publication practices are important to identify, acknowledge, and generate awareness for ethical and credible science. Academic requirement for research thesis, and 'publish or perish' culture of academia for career evaluation of faculties contribute to authorship misconducts. The authorship criteria have been clearly outlined by international guidelines like International Committee of Medical Journals Editors, Committee on Publication Ethics, Council of Science Editors, World Association of Medical Editors. However, the practice of guide, co-guide as authors in students' thesis articles continues as inappropriate authorship. This is a topic which requires more debate in academia. Historical practices of academia, the power dynamics, and the guidelines of the journals vary and make this dispute even more complicated. In Nepal, we need to expand the discussion among stakeholders from academia, universities, monitoring bodies, ethical committees to journals for a consensus; to 'put to rest' this issue and be in line with the international guidelines. Keywords: Authorship guideline; journal article publication; research thesis guide co-guide supervisor.

Lymphadenectomy Around Inferior Mesenteric Artery in Low-Tie vs High-Tie Laparoscopic Anterior Resection: Short- and Long-Term Outcome of a Cohort of 614 Rectal Cancers.

BACKGROUND: Preservation of the left colic artery in low-tie (LT) of inferior mesenteric artery remains controversial compared to high-tie (HT) in the colon and rectal cancers, for lymph node dissection, anastomotic leakage, and oncological outcome. This cohort study aims to analyze short- and long-term outcomes of laparoscopic anterior resections in LT vs HT for rectal cancers. METHODS: We analyzed a cohort of laparoscopic AR for RC from 2013 to 2016 at Renji Hospital, Shanghai, China. Short- and long-term outcome in LT vs HT group were compared for clinico-demographic characteristics, operative-time, lymph node dissection, short-term 30-day outcome, and long-term 3- and 5-year overall survival as well as disease-free survival. The x2, t-test, and logistic regressions analysis were used and p<0.05 was considered significant. RESULTS: The cohort consisted of 614 laparoscopic AR with LT (236) and HT (378). The clinicodemographic characteristics were comparable among the groups. The surgery took longer in LT. The yield of LND was similar. Leakage occurred in 12.21% (n=75). Leakage was fewer in LT than HT, 8.89% vs 14.28%, p=0.047. The postoperative severe complications were higher in HT. The 30-day mortality was nil. The long-term 3- and 5-year overall survival and disease-free survival were similar in LT and HT. CONCLUSION: The LT with preservation of left colic artery had similar lymph node yield, but lower leakage and complications than HT in laparoscopic anterior resections for rectal cancers. The long-term 3- and 5-year overall and disease-free survival were similar in the two groups.

AIM2 Inhibits BRAF-Mutant Colorectal Cancer Growth in a Caspase-1-Dependent Manner.

Absent in melanoma 2 (AIM2), a DNA sensor that plays an important role in natural immunity system, has been reported to participate in colorectal cancer (CRC) development. However, the functional role of AIM2 in BRAF-mutant CRC remains unclear. In this study, we first investigated AIM2 expression level in BRAF-mutant CRC tumor tissues. Overexpression of AIM2 in CRC cells was performed to investigate the effect of AIM2 on CRC cell viability, and cell death detection and caspase activity assay were performed to explore the mechanism that AIM2 impacts the growth of BRAF-mutant CRC cells. Moreover, we confirmed the antitumor effect of AIM2 in BRAF-mutant CRC cell-derived tumor xenograft (CDX) models as well as patient-derived organoids (PDOs). Herein, we reported that AIM2 expression was lower in BRAF-mutant than that in BRAF wild-type CRC tumor tissues. Restoring the expression of AIM2 in BRAF-mutant CRC cells greatly inhibits the tumor cell growth by inducing necrotic cell death. Mechanism studies revealed that AIM2-induced cell death is in a caspase-1-dependent manner. Additionally, overexpression of AIM2 significantly inhibits tumor growth and metastasis in BRAF-mutant CRC in vivo, which was further confirmed in BRAF-mutant CRC PDOs. Taken together, our data suggested that AIM2 inhibits BRAF-mutant colon cancer growth in a caspase-1-dependent manner, which may provide evidence to understand the pathogenesis of CRC with BRAF-mutant, as well as new strategies for manipulation of CRC.

Variation in additional testing and patient outcomes after stress echocardiography or myocardial perfusion imaging, according to accreditation status of testing site.

BACKGROUND: The purpose of the present study was to determine whether patients receiving a stress echocardiogram or myocardial perfusion imaging (MPI) test have differences in subsequent testing and outcomes according to accreditation status of the original testing facility. METHODS AND RESULTS: An all-payer claims dataset from Maine Health Data Organization from 2012 to 2014 was utilized to define two cohorts defined by an initial stress echocardiogram or MPI test. The accreditation status (Intersocietal Accreditation Commission (IAC), American College of Radiology (ACR) or none) of the facility performing the index test was known. Descriptive statistics and multivariate regression were used to examine differences in subsequent diagnostic testing and cardiac outcomes. We observed 4603 index stress echocardiograms and 8449 MPI tests. Multivariate models showed higher odds of subsequent MPI testing and hospitalization for angina if the index test was performed at a non-accredited facility in both the stress echocardiogram cohort and the MPI cohort. We also observed higher odds of percutaneous coronary interventions (PCI) performed (OR 1.68, 95% CI 1.13-2.50), if the initial MPI test was done in a non-accredited facility. CONCLUSION: Cardiac testing completed in non-accredited facilities were associated with higher odds of subsequent MPI testing, hospitalization for angina, and PCI.

Electromagnetic Versus Blind Guidance of a Postpyloric Feeding Tube in Critically Ill Children.

BACKGROUND AND OBJECTIVES: Postpyloric feeding tube placement is a time-consuming procedure associated with multiple attempts and radiation exposure. Our objective with this study is to compare the time, attempts, and radiation exposure using the electromagnetic versus blind method to place a postpyloric feeding tube in critically ill children. Our hypothesis is that using electromagnetic guidance decreases the procedure time, number of x-rays, and number of attempts, compared to the blind method. METHODS: Eleven pediatric nurses participated in a randomized controlled intention-to-treat study at an academic pediatric medical, surgical, and congenital cardiac ICU. University of Texas Health Epidemiology and Biostatistics generated a randomization sequence with sealed envelopes. A standard (2-sided) F-test of association between the electromagnetic and blind method yielded 40 subjects with 86% power. Data were analyzed with Fisher's exact test for categorical variables and the Wilcoxon rank test for continuous variables, with data documented as median (interquartile range [IQR]). RESULTS: We randomly assigned 52 patients to either the electromagnetic (n = 28) or blind method (n = 24). The number of attempts and radiographs was at a median of 2 (IQR: 1-2.25) using the blind method, compared to the electromagnetic method at a median of 1 (IQR: 1.0-1.0; P = .001). Successful guidance was 96.4% with the electromagnetic method, compared to only 66.7% with the blind technique (P = .008). The total time required was 2.5 minutes (IQR: 2.0-7.25) with the electromagnetic method, compared to 19 minutes (IQR: 9.25-27.0) for the blind method (P = .001). CONCLUSIONS: Electromagnetic guidance is a superior, faster, and overall safer method to place a postpyloric feeding tube in critically ill children.

Shortened Preoperative Fasting Time to Allow Oral Rehydration Solution Clear Liquid up to Two Hours before Elective Major Surgery in Adults.

OBJECTIVE: To generate evidence of feasibility to allow clear liquid 2 hours before elective surgery. STUDY DESIGN: Cross-sectional observational study. PLACE AND DURATION OF STUDY: The Department of Surgery, Patan Hospital, Patan Academy of Health Sciences, Nepal, from October to December 2016. METHODOLOGY: One hundred consecutive adult elective major surgery patients of American Society of Anesthesiologist criteria 1 or 2 were enrolled. The protocol was discussed with patients, nurses, anesthetists and surgeons to allow 500 ml clear liquid (ORS) up to 0600 hours on the day of surgery to maintain minimum of 2 hours (h) nil per os (NPO) before surgery. Compliance, discomfort, nausea and vomiting were observed. Institutional review committee approved the study. Microsoft excel was used for descriptive analysis. RESULTS: All 100 patients completed the protocol of shortened fasting time. Two patients had incomplete records and were excluded from analysis. Among the 98 patients analysed, age was 48 ±12.38 years with 74 females (75.51% of 98). There were 68 gastrointestinal, 20 urosurgery and 10 others surgeries. There was no discomfort, nausea or vomiting reported due to ORS 2-h before elective surgery. CONCLUSION: Preoperative clear liquid up to 2-h before elective surgery in adults is feasible and safe in our set-up to shorten the fasting time.

Quality of Clinical Notes: Lesson Learned from Elective Surgery Patients Admitted at University Teaching Hospital.

BACKGROUND: Informative relevant documentation regarding course of treatment minimizes errors, provides data for evidence based practice and legality. However, the clinical notes are often inadequate. This study aims to analyse quality of structured clinical notes in surgical patients. METHODS: This cross sectional study from Oct 1, 2015 in department of surgery included 100 clinical notes randomly selected by lottery. The entries in notes were predefined. There were 29 general entries (nine for identification, eleven for admission details, eight for treatment progress, and one for handwriting). Three additional entries were for discharge patients. The decision for entries was based on consensus meeting in surgery department. Microsoft excel was used for data entry and descriptive analysis. RESULTS: There were 100 clinical notes analysed, 62 non-discharge and 38 discharge patients. Four (out of 62) non-discharge had all 29 entries documented. Two (out of 38) in discharge had all 32 entries documented. The "date of entries, clinician name and designation" were mentioned in 12%, 13% and 10%, respectively. The progress on diet was recorded in 53%, investigations in 72% and intervention details in 73%. Handwriting was difficult to read in 21%. In 13 (out of 100) the identification information was incomplete. Discharge lacked details of home advice in 11%. CONCLUSIONS: The quality of clinical note of elective surgery patients needs improvement on documentation in all domains of identification, admission, progress and discharge.

The Gift Box Open Achilles Tendon Repair Method: A Retrospective Clinical Series.

Previous biomechanical studies have shown that the gift box technique for open Achilles tendon repair is twice as strong as a Krackow repair. The technique incorporates a paramedian skin incision with a midline paratenon incision, and a modification of the Krackow stitch is used to reinforce the repair. The wound is closed in layers such that the paratenon repair is offset from paramedian skin incision, further protecting the repair. The present study retrospectively reviews the clinical results for a series of patients who underwent the gift box technique for treatment of acute Achilles tendon ruptures from March 2002 to April 2007. The patients completed the Foot Function Index and the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale. The tendon width and calf circumference were measured bilaterally and compared using paired t tests with a 5% α level. A total of 44 subjects, mean age 37.5 ± 8.6 years, underwent surgery approximately 10.8 ± 6.5 days after injury. The response rate was 35 (79.54%) patients for the questionnaire and 20 (45.45%) for the examination. The mean follow-up period was 35.7 ± 20.1 months. The complications included one stitch abscess, persistent pain, and keloid formation. One (2.86%) respondent reported significant weakness. Five (14.29%) respondents indicated persistent peri-incisional numbness. The range of motion was full or adequate. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot scale score was 93.2 ± 6.8) and the mean Foot Function Index score was 7.0 ± 10.5. The calf girth and tendon width differences were statistically significantly between the limbs. The patients reported no repeat ruptures, sural nerve injuries, dehiscence, or infections. We present the outcomes data from patients who had undergone this alternative technique for Achilles tendon repair. The technique is reproducible, with good patient satisfaction and return to activity. The results compared well with the historical repeat rupture rates and incidence of nerve injury and dehiscence for open and percutaneous Achilles tendon repairs.

A systematic review of complications and failures associated with medial patellofemoral ligament reconstruction for recurrent patellar dislocation.

BACKGROUND: Patellofemoral instability affects activities of daily living and hinders athletic participation. Over the past 2 decades, more attention has been paid to medial patellofemoral ligament (MPFL) reconstruction for the treatment of recurrent patellar dislocations/subluxations. Numerous techniques have been reported; however, there is no consensus regarding optimal reconstruction. PURPOSE: This study sought to report on the various techniques for MPFL reconstruction described in the literature and to assess the rate of complications associated with the procedure. STUDY DESIGN: Meta-analysis. METHODS: A systematic review of the literature was performed in early October 2010 using keywords "medial patellofemoral ligament," "MPFL," "reconstruction," "complication(s)," and "failure(s)." Articles meeting the inclusion criteria were reviewed. Graft choice, surgical technique, outcome measures, and complications were recorded and organized in a database. Descriptive statistical analysis was performed on the data collected. RESULTS: Twenty-five articles were identified and reviewed. A total of 164 complications occurred in 629 knees (26.1%). These adverse events ranged from minor to major including patellar fracture, failures, clinical instability on postoperative examination, loss of knee flexion, wound complications, and pain. Twenty-six patients returned to the operating room for additional procedures. CONCLUSION: Medial patellofemoral ligament reconstruction has a high rate of success for patients with patellofemoral instability; however, the complication rate of 26.1% associated with this procedure is not trivial. This study quantified complications and documented the variety of complications reported in outcomes-based literature.

Determination of the Interday and Intraday Reliability of Serum Cartilage Oligomeric Matrix Protein in a Physically Active Population.

OBJECTIVE: To determine the intraday and interday reliability of serum cartilage oligomeric matrix protein (sCOMP) in a physically active population with no history of lower extremity surgery. DESIGN: A repeated-measures reliability study was employed to determine the intraday and interday reliability of sCOMP in a physically active cohort. A total of 23 subjects were recruited to the laboratory on 3 separate occasions for nonfasting serum collection. Subjects had no history of lower extremity surgery and were free from acute injury within the last 3 months. RESULTS: Our results indicate strong reliability for both intraday intraclass correlation coefficient (ICC) (0.76) and interday ICC (0.74) sCOMP values. CONCLUSION: Our results demonstrate that following 30 minutes of inactivity, nonfasting serum samples remain stable over the course of 1 day and between 2 consecutive days in a healthy population with no history of lower extremity surgery. Future research studies are needed to further investigate the magnitude of change in this biomarker for patients with acute articular cartilage damage to determine its appropriateness for use in this population and for varying degrees of articular cartilage severity.

Is prophylactic placement of drains necessary after subtotal gastrectomy?

AIM: To determine the evidence-based values of prophylactic drainage in gastric cancer surgery. METHODS: One hundred and eight patients, who underwent subtotal gastrectomy with D1 or D2 lymph node dissection for gastric cancer between January 2001 and December 2005, were divided into drain group or no-drain group. Surgical outcome and post-operative complications within four weeks were compared between the two groups. RESULTS: No significant differences were observed between the drain group and no-drain group in terms of operating time (171 +/- 42 min vs 156 +/- 39 min), number of post-operative days until passage of flatus (3.7 +/- 0.5 d vs 3.5 +/- 1.0 d), number of post-operative days until initiation of soft diet (4.9 +/- 0.7 d vs 4.8 +/- 0.8 d), length of post-operative hospital stay (9.3 +/- 2.2 d vs 8.4 +/- 2.4 d), mortality rate (5.4% vs 3.8%), and overall post-operative complication rate (21.4% vs 19.2%). CONCLUSION: Prophylactic drainage placement is not necessary after subtotal gastrectomy for gastric cancer since it does not offer additional benefits for the patients.
