Post bariatric surgery complications, nutritional and psychological status.

BACKGROUND AND OBJECTIVES: Bariatric surgery becomes the final option for managing severe obesity. This study aims to identify the complications, changes in anthropometry, adherence to dietary recommendations, and psychological well-being of post-bariatric surgery patients. METHODS AND STUDY DESIGN: An observational study was conducted on 63 post-bariatric surgery patients who had undergone bariatric surgery between two weeks and five years after surgery. The participants were assessed for the complications experienced, current comorbidities, anthropometric changes, dietary intake, and psychological well-being. A three-day, 24-hour diet recall was done to assess the dietary intake of the patients. The mean macronutrient and micronutrient intakes were compared to several available recommendations. The DASS-21 questionnaire was administered to determine the psychological well-being of the participants. RESULTS: The most common complications experienced by patients after bariatric surgery were hair loss (50.8%), gastroesophageal reflux disease (GERD) (49.2%), and vomiting (41.3%). There were significant differences in mean weight before (129.5 (33.0) kg/m2) and after (85.0 (32.0) kg/m2) bariatric surgery (p<0.001). The prevalence of clinically severe obesity declined by 55%. Overall, patients had insufficient intake of some nutrients such as protein, fat, calcium, and iron. Majority of the patients experienced a normal level of stress, anxiety, and depression, but some had mild (3.2%), moderate (4.8%), and severe anxiety (1.6%). CONCLUSIONS: There were drastic improvements in patients' weight following bariatric surgery. However, there were several complications including nutrient deficiencies. Due to the anatomical changes in the gastrointestinal tract, patients must comply with the dietary and lifestyle changes and follow up with the healthcare professional. A nutrition module will be helpful for patients to prepare for and adapt to the changes after bariatric surgery.

Comparing Low Volume Versus Conventional Volume of Polyethylene Glycol for Bowel Preparation during Colonoscopy: A Randomised Controlled Trial.

Background: Polyethylene glycol (PEG) solution is widely used as a colonoscopic bowel cleaning agent, although some patients are intolerant due to the need for ingesting large solution volumes and unpleasant taste. A low-volume solution may enhance patient tolerability and compliance in bowel preparation. Accordingly, this study compared the effectiveness of two difference PEG volumes for bowel preparation before colonoscopy in terms of bowel cleanliness, completeness of colonoscopy, patient tolerability and colonoscopy duration. Methods: Using a prospective randomised controlled single-blinded study design, 164 patients scheduled for colonoscopy were allocated to two groups (n = 82 patients in each) to receive either the conventional PEG volume (3 L, control group) or the low volume (2 L, intervention group). The Boston Bowel Preparation Scale (BBPS), a validated scale for assessing bowel cleanliness during colonoscopy, was used to score bowel cleanliness in three colon segments. Secondarily, colonoscopy completeness, tolerability to drinking PEG and the duration of colonoscopy were compared between the groups. Results: There were no statistically significant differences between the two intervention groups in terms of bowel cleanliness (P = 0.119), colonoscopy completion (P = 0.535), tolerability (P = 0.190) or the amount of sedation/analgesia required (midazolam, P = 0.162; pethidine, P = 0.708). Only the duration of colonoscopy differed between the two groups (longer duration in the control group, P = 0.039). Conclusion: Low-volume (2 L) PEG is as effective as the standard 3 L solution in bowel cleaning before colonoscopy; however, the superiority of either solution could not be established.

The effect of pre-endoscopy maltodextrin beverage on gastric residual volume and patient's well-being: a randomised controlled trial.

Prolonged fasting prior to oesophagogastroduodenoscopy (OGDS) could be noxious to patients' well-being. Strict fasting protocol has been used prior to OGDS with the concern of reduced visibility or suboptimal endoscopic assessment. Maltodextrin beverages were also commonly used as the pre-operative carbohydrate loading in enhanced recovery after surgery (ERAS) protocol. Our study aimed to look for the effects of maltodextrin beverage 2 h before OGDS on gastric residual volume and patient's well-being scores. This was a single-blinded, stratified randomised controlled trial, comparing control group (A, received 400 ml of plain water) and carbohydrate loading group (B, received 400 ml of Carborie). The primary objectives were to measure the gastric residual volume (GRV) and patient's well-being scores using visual analogue scale (VAS) scores for hunger, thirst, anxiety, tiredness and general discomfort. Of 80 randomised patients, 78 completed the study (38 received plain water and 40 Carborie). The median (IQR) GRV was not significantly different between group A and B (5.0 ml (20) vs 4.0 ml (19), p = 0.777). Both groups showed significant reduction in VAS scores in all five parameters (p ≤ 0.001). There were no complications attributed to endoscopy in either group. Pre-endoscopy maltodextrin beverage is as safe as clear water with improved patient's well-being in both groups.Clinical Trial Registration: NCT05106933.

Efficacy and safety of pre-gastroscopy commercial carbohydrate-rich whey protein beverage vs. plain water: a randomised controlled trial.

Clinical benefits and safety of carbohydrate loading pre-gastroscopy remain unclear. We aimed to determine the effects of a commercial carbohydrate-rich whey protein beverage versus plain water given pre-gastroscopy on gastric residual volume and well-being, and to determine adverse events. This was a single centre, single-blinded, parallel-group, sex-stratified randomized controlled trial. Participants were randomized either to carbohydrate-rich whey protein beverage group (Resource®, Nestle Health Science) or control group (250 ml plain water) given pre-gastroscopy. Gastric contents were aspirated into a suction reservoir bottle to determine the gastric residual volume (GRV). Visual analogue scale (VAS) of well-being (anxiety, hunger, thirst, tiredness, and weakness) was compared before and after the intervention. Adverse events were also evaluated post-intervention. Of 369 screened, 78 participants (36 males, mean age 49 ± 14.3 years) were randomized. Compared with the control group, carbohydrate beverage was associated with significantly higher GRV (p < 0.001). Anxiety was less after intervention with carbohydrate beverage (p = 0.016), and after adjustment for confounders, fewer participants also experienced hunger (p = 0.043) and thirst (p = 0.021). No serious adverse events were reported with both interventions. Commercial carbohydrate-rich whey protein beverage is associated with higher gastric residual volume, better well-being and safe.Trial registration Clinicaltrial.gov.

Factors associated with delay in seeking care for breast symptoms.

BACKGROUND: Breast cancer is the most common cancer in women worldwide. Early detection and intervention are associated with better prognosis and survival. The study aim was to investigate the factors associated with delayed presentation among women with breast symptoms. METHODS: After ethics approval, a cross-sectional study was conducted from January to October 2020 in women with new breast cancer symptoms at their first visit to our clinic. The "Delayed Presentation" questionnaires in the Malay language were used and distributed among the participants. Demographic data and presentation time were recorded. Presentation time was defined as the duration of symptoms prior to visiting any health care facilities. Respondents with presentation times > 90 days comprised the delayed group. The potential factors associated with the delayed presentation were analyzed using cross-tabulation and multiple logistic regression. RESULTS: There were 106 respondents to the questionnaire, with a mean age of 34.0 (SD: 11.2) years, and 73.6% (n = 78) were < 39 years old. A total of 35.8% (n = 38) visited the local government clinic first and only 28.3% (n = 30) came to the BestARi clinic directly. The reasons for presentation were a palpable breast lump on breast self-examination (75.5%, n = 80), mastalgia (15.1%, n = 16), nipple discharge (5.7%, n = 6), skin changes (0.9%, n = 1), and others (2.8%, n = 3). Among the respondents, 10.4% (n = 11) had alternative treatments prior to presentation to a hospital. The mean presentation time was 98.9 (SD: 323.7) days. Most of the participants (61.3%, n = 65) presented to us within 1 month. The delayed presentation group accounted for 19.8% (n = 21) of the respondents. The factor that was significantly associated with delayed presentation was the participants' perception of symptoms as not dangerous (adjusted OR 3.05, 95% CI 1.11, 8.38). CONCLUSIONS: The percentage of delayed presentations among our patients was lower than the percentage reported in a previous study. Interpretation of a symptom as harmless by the respondent was the only factor significantly associated with delayed presentation.

Lived Experience after Bariatric Surgery among Patients with Morbid Obesity in East Coast Peninsular Malaysia: A Qualitative Study.

Living with morbid obesity is challenging since it affects various dimensions of life. Sustainable weight loss via bariatric surgery helps people suffering from morbid obesity to lead a healthy and meaningful life. This study highlights the challenges before bariatric surgery and the impact on one's life. A phenomenological approach was employed using in-depth interviews with 21 participants (15 females and 6 males) who had undergone surgery at least 6 months prior to the study with the mean age of 42.6 years. Due to excess body weight, the physical limitation had a serious negative impact on their social life, making them targets of bias and stigmatisation. Surgery was the best option for them to attain sustainable weight loss and to lead a new life. However, a few participants struggled with the side effects of surgery. Five themes were discovered, namely, (1) social restraint; (2) experiencing bias and stigmatisation; (3) bringing new life; (4) boosting self-esteem; and (5) facing the negative side of surgery. This study serves as a platform to explore the difficulties faced by people with morbid obesity and the changes that the participants experienced after the surgery for future intervention to curb the rising number of people with morbid obesity.

The Use of M2-Pyruvate Kinase as a Stool Biomarker for Detection of Colorectal Cancer in Tertiary Teaching Hospital: A Comparative Study.

PURPOSE: Guaiac fecal occult blood test (gFOBT) has been the standard for colorectal screening but it has low sensitivity and specificity. This study evaluated the use of fecal tumor M2-pyruvate kinase (M2-PK) for detection of colorectal cancer and to compare with the current surveillance tool; gFOBT in symptomatic adult subjects underwent colonoscopy. METHODS: Stool samples were collected prospectively from symptomatic adults who had elective colonoscopy from September 2014 to January 2016 and were analyzed with the ScheBo M2-PK Quick test and laboratory detection of fecal hemoglobin. RESULTS: The results were correlated to the colonoscopy findings and/or histopathology report. Eighty-five subjects (age of 56.8 ± 15.3 years [mean ± standard deviation]) were recruited with a total of 17 colorectal cancer (20.0%) and 10 colorectal adenoma patients (11.8%). The sensitivity of M2-PK test in colorectal cancer detection was higher than gFOBT (100% vs. 64.7%). M2-PK test had a lower specificity when compared to gFOBT (72.5% vs. 88.2%) in colorectal cancer detection. The positive and negative predictive values were 47.2% and 100% for M2-PK test and 57.9% and 90.9% for gFOBT. CONCLUSION: Fecal M2-PK Quick test has a high sensitivity for detection of colorectal cancer when compared to gFOBT, making it the potential choice for colorectal tumor screening biomarker in the future.

Predictors of early postoperative hypocalcemia after total parathyroidectomy in renal hyperparathyroidism.

PURPOSE: Patients with secondary hyperparathyroidism are at high risk for developing postoperative hypocalcemia. However, there are limited data regarding predictors of postoperative hypocalcemia in renal failure patient with secondary hyperparathyroidism. This study aimed to determine the clinical presentations of renal hyperparathyroidism and the predictors of early postoperative hypocalcemia after total parathyroidectomy. METHODS: Data of patients with renal hyperparathyroidism who underwent total parathyroidectomy between January 2007 to December 2014 were reviewed retrospectively. Patients were divided into 2 cohort groups according to their serum calcium levels within 24 hours of parathyroidectomy: the hypocalcemia group (calcium levels of 2 mmol/L or less), and the normocalcemia group (calcium levels more than 2 mmol/L). With the use of multivariable logistic regression analyses, the predictors of early postoperative hypocalcemia after total parathyroidectomy in patients with renal hyperparathyroidism were investigated. RESULTS: Among 68 patients, 56 patients (82.4%) were symptomatic preoperatively. Fifty patients (73.5%) presented with bone pain and 14 patients (20.6%) had muscle weakness. Early postoperative hypocalcemia occurred in 25 patients (36.8%). Preoperative alkaline phosphatase level was the predictor of early postoperative hypocalcemia (adjusted odds ratio, 1.004; 95% confidence interval, 1.001-1.006; P = 0.002). CONCLUSION: Results from our study show that most of the patients with renal hyperparathyroidism were symptomatic preoperatively and the most common clinical presentations were bone pain and muscle weakness. The significant predictor of early postoperative hypocalcemia after total parathyroidectomy was the preoperative alkaline phosphatase levels.

Collapsed wall: destructive and reconstructive surgery of anterior abdominal wall tumour in a young girl.

Natural history of abdominal wall soft tissue sarcoma is still poorly understood due to its rarity. In unpublished data of our institution, only seven cases of abdominal wall soft sarcoma with ICD-10 coding of 49.4 were found for past 10 years. We illustrate a case of juvenile fibrosarcoma of anterior abdominal wall. This is a case of young girl with anterior abdominal wall tumour, underwent wide local excision with immediate reconstruction. There are few options of surgical treatment for this case, but which is the best. It is always a challenge in managing young patient with giant abdominal wall defect in view of long term effect namely weakened abdominal wall, pregnancy related issue and risk of herniation and surgical site recurrence as well.

Postoperative major surgery patients developing silent deep vein thrombosis: A prospective observational study.

Surgical patients are at high risk for developing deep vein thrombosis (DVT). There are many reports concerning DVT, but little is known about silent deep vein thrombosis (sDVT). This study aimed to determine the incidence of sDVT. Secondary objective is to identify the associated factors for the use of DVT prophylaxis and Caprini risk scores among major surgery patients. This prospective observational study involved postoperative surgical patients who are at risk of developing sDVT. The Caprini risk-assessment scores were calculated, and each subject had a preoperative and postoperative compression ultrasound complemented by duplex venous ultrasonography of deep venous system. No patient from the study experienced sDVT. There were significant associations between Caprini risk score group (odds ratio, 8.16; 95% confidence interval [CI], 1.01-68.74; P = .016) and the use of central venous catheter (odds ratio, 6.34; 95% CI, 1.62-24.80; P = .008) with DVT prophylaxis. Interestingly, the use of central venous catheter resulted in more than four-point increment of Caprini risk scores (mean increment, 4.19; 95% CI, 3.16-5.21; P < .001). Besides that, age was also significantly associated with Caprini risk scores (ß coefficient, 0.06; 95% CI, 0.02-0.11). Result from our study shows that the sDVT was nonexistent in this study setting. High-Caprini risk score group and the presence of central venous catheter were the significant predictor factors for the use of DVT prophylaxis. Significant predictor factors for Caprini risk scores were age and the presence of central venous catheter.

Solid variant of papillary thyroid carcinoma in a 14-year-old girl.

Solid variant of papillary thyroid carcinoma (PTC) is a rare, poorly characterised variant and predominantly reported in children with a history of radiation exposure. This variant has a high propensity for extra-thyroidal extension and cervical lymph node metastases. A 14-year-old Malay girl who had no history of radiation exposure, presented with multiple cervical lymphadenopathy and it was clinically suspicious for tuberculosis or lymphoma. An incisional biopsy revealed a metastatic PTC. The patient underwent total thyroidectomy with bilateral lateral neck dissection and histopathology report was solid variant of PTC. Whole-body I(131) scan was performed which revealed an intense tracer uptake in the neck. She was planned for radioactive iodine ablation and now on regular follow-up for monitoring of possible tumour metastasis.
