Probiotic treatment improves post-traumatic stress disorder outcomes in mice.

Post-traumatic stress disorder (PTSD) is a mental disorder resulting from traumatic events which are characterized primarily by anxiety and depressive disorder. In this study, we determine the role of gut bacteria in PTSD. PTSD-like symptoms were produced by single prolonged stress (SPS). SPS animals showed increased levels of anxiety as measured by the elevated plus maze test, while depressive behaviour was confirmed using sucrose preference, force swim, and tail suspension tests. Gut dysbiosis was confirmed in PTSD animals by next-generation sequencing of 16 s RNA of faecal samples, while these animals also showed increased intestinal permeability and altered intestinal ultrastructure. Probiotic treatment increases beneficial microbiota, improves intestinal health and reduces PTSD-associated anxiety and depression. We also found a decrease in cortical BDNF levels in PTSD animals, which was reversed after probiotic administration. Here, we establish the link between gut dysbiosis and PTSD and show that probiotic treatment may improve the outcome of PTSD like symptoms in mice.

Anthropometric Measurements of Foot in Undergraduate Medical Students of a Medical College: A Descriptive Cross-sectional Study.

INTRODUCTION: Anthropometry is one of the important parameters for differentiation of sex which varies significantly based on hereditary, geographical, racial, sexual, and other factors. This study was done to provide baseline foot anthropometric data for Nepali medical students to improve the accuracy of stature estimations and enhance forensic and clinical applications. The aim of the study was to calculate anthropometric measurements of foot in undergraduate medical students of a medical college. METHODS: A descriptive cross-sectional study was conducted on medical students studying at a tertiary care hospital during the period of November 6, 2022 to February 28, 2023 after obtaining ethical clearance from the Institutional Review Committee (Reference number: 06/2022). A total population sampling method was used. The present study was conducted to determine the mean foot index from the right and left foot, mean measurements of the left and right foot, and sex-related dimensions of the foot in Nepalese medical students. Data were collected and analyzed using SPSS. RESULTS: Out of 115 participants, the mean foot index for male and female were 38.34±2.13 and 39.33±2.22 respectively. The mean length of the right foot for males and females were 24.12±0.98 cm and 22.10±1.25 cm respectively. The mean length of the left foot for males and females was 24.20±1.06 cm and 22.07±1.24 cm respectively. CONCLUSIONS: This study provides mean values of different measurements of the right and left foot of both sexes of the age group of 18-24 years in the students of a medical college.

Mastalgia and Why It Should Be Evaluated With Imaging in Areas Where Use of Breast Cancer Screening Services are Unsatisfactory.

Objective: Mastalgia or breast pain is a very common symptom in women attending breast clinic. The aim of this study was to evaluate whether imaging for mastalgia leads to cancer detection in an area where routine breast cancer screening services are underutilized. Materials and Methods: This prospective study was performed between 1st March 2021 to 31st January 2023 at a tertiary care academic institution of central India. All patients underwent through clinical examination by a surgeon. Then patients were referred for ultrasound and/or X-ray mammography (MMG) depending on age. Cancer detection rate was calculated. Results: The final cohort consisted of 176 patients with mastalgia and without any abnormality on clinical breast examination. Sixteen patients had mass lesion on radiology and core needle biopsy resulted as infiltrating duct carcinoma in 7 patients and benign phylloides tumor in one patient. Overall case detection rate for cancer was 4%. Conclusion: The breast cancer detection rate in patients presenting with mastalgia was low. However, in the absence of routine mammographic screening in the Indian general population, these would have been missed. Hence, diagnostic assessment for mastalgia is an appropriate strategy in countries where routine screening MMG is lacking.

Is it time to say goodbye to drainage after axillary lymph node dissection in breast cancer? A randomized clinical trial of systemic tranexamic acid combined with topical epinephrine + xylocaine versus conventional drainage.

Drainage after axillary lymph node dissection is a major cause of morbidity. We evaluated the outcomes of topical epinephrine with xylocaine + systemic tranexamic acid (EXT) after axillary lymph node dissection. The primary endpoint was the rate of seroma development. This resulted in reduced hospital stay with similar rates of seroma as drainage after axillary lymph node dissection; thereby making it possible to avoid drainage.

A role for the circadian photoreceptor CRYPTOCHROME in regulating triglyceride metabolism in Drosophila.

The biological rhythms generated by the endogenous circadian clocks across the tree of life regulate numerous behavioural, metabolic and physiological processes. Although evidence from various studies in Drosophila melanogaster indicates the importance of the core circadian clock genes in the intricate interplay between the circadian clock and metabolism, little is known about the contribution of the circadian photoreceptor/s in this process. The deep brain circadian photoreceptor CRYPTOCHROME (CRY) is essential for resetting the clock in response to light and is also highly expressed in metabolically active tissues in Drosophila. In this study, we sought to explore the possible roles played by CRY in triglyceride metabolism. We observed that the cry mutant (cry01) flies exhibited increased starvation resistance and triglyceride levels under both 12-hour (h) light:12 h dark cycle (LD) and under constant light (LL) compared to the control w1118 flies. We also observed that cry01 flies had significantly increased food intake, glycogen concentrations and life span under LD. In addition, cryptochrome seemed to affect triglyceride levels in adult flies in response to calorie-restricted and high-fat diets. These results suggest a role for the circadian photoreceptor CRY in triglyceride metabolism in Drosophila.

Addressing disparities in rural and remote access for rheumatology practice through a transformative tele-healthcare delivery system: Experience of a large cohort of patients in eastern India.

Background We present the experience of telerheumatology consultation services carried out in an eastern state of India. Methods We did this prospective, observational study of patients with rheumatological disorders and followed through telemedicine between December 2015 and May 2019. Results During the study period, we provided teleconsultation to 3583 patients with the help of 11 201 telemedicine visits. Patients resided at a median distance of 248 (13 to 510) km from the telemedicine hub. The cumulative savings of the patients as a result of this service were ₹2.4 crore (24 million). The median travel time saved was 7 hours (30 minutes to 12 hours) per patient per visit and a median of ₹6700 was saved per visit per patient. Conclusion Sustained efforts over a long period can lead to the delivery of essential rheumatology services via telemedicine to an under-priviledged population, reduce the financial burden of the poor, and help women to access healthcare services in remote parts of low- and middle-income countries (LMICs).

Comparison of clinical and patient-reported outcomes in patients with benign euthyroid solitary nodules after ultrasound-guided percutaneous microwave ablation and endoscopic thyroidectomy.

BACKGROUND: Percutaneous ultrasound-guided microwave ablation (MWA) for benign solid thyroid nodules is the newest modality for treatment. However, the differences in treatment outcomes between MWA and endoscopic thyroidectomy vestibular approach (TOETVA) for patients with benign euthyroid solitary nodules remain unknown. We are sharing initial results from our prospective study. METHODS: Prospective study between January 2022 and December 2023 was conducted and data were noted at 3 time points in patients planned for treatment (Preoperative, 1 week, and 12 months). Main outcome measures were clinical outcome and comparison of thyroid-related quality of life using the ThyPRO-39hin and swallowing-related quality of life using the SWAL-QoL. RESULTS: Of the 36 included patients, 20 patients underwent TOETVA and 16 underwent MWA. Both the groups were comparable in terms of demographic and clinicopathological profiles. The nodule volume reduction rate of patients at 12 months after MWA was 75.10% and 100% for TOETVA. The mean preoperative ThyPRO-39hin and SWAL-QoL scores were comparable in all domains between the two groups. Mean ThyPRO-39hin and SWAL-QoL scores on postoperative day 7 were significantly better in the MWA group in domains impaired social life (p < 0.0001) and impaired daily life (p = 0.0002). However, at the end of 12 months, mean ThyPRO-39hin and SWAL-QoL scores became significantly better in the TOETVA group as compared to the MWA group. CONCLUSION: Our findings suggest that transoral endoscopic thyroidectomy results in significant superior clinical outcome, thyroid-related quality of life, and swallowing-related quality of life in the long term.

Unveiling perceptions regarding post mastectomy breast reconstruction: A questionnaire-based survey of patients from central India.

INTRODUCTION: Post mastectomy breast reconstruction uptake remains low in the developing countries. We examined patient perspectives about it in a cohort of Indian breast cancer patients. METHODS: This prospective study was conducted at a tertiary care center in central India. All post mastectomy patients for breast cancer were interviewed via a survey questionnaire to assess their perspective regarding post mastectomy breast reconstruction. RESULTS: None of the 192 patients underwent immediate or delayed reconstruction by the end of 24 months follow-up. Age, education level, occupation and marital status did not affect the uptake of post mastectomy breast reconstruction. The most common patient-reported reasons for not having reconstruction were the desire to avoid additional surgery and the belief that it was not important (80% for each). System related factors such as additional cost of surgery and additional length of stay were reported to be important by 55% and 65% patients respectively. CONCLUSION: Our survey of 192 post mastectomy breast cancer patients showed that none opted for post mastectomy reconstruction, suggesting significant barriers to it. Understanding and addressing these barriers are crucial to ensuring comprehensive care for these breast cancer patients.

Genomic sequencing and neutralizing serological profiles during acute dengue infection: A 2017 cohort study in Nepal.

Dengue virus (DENV) is a mosquito-borne flavivirus that poses a threat to nearly 50% of the global population. DENV has been endemic in Nepal since 2006; however, little is known about how DENV is evolving or the prevalence of anti-DENV immunity within the Nepalese population. To begin to address these gaps, we performed a serologic and genetic study of 49 patients from across Nepal who presented at central hospitals during the 2017 dengue season with suspected DENV infection. Of the 49 subjects assessed, 21 (43%) were positive for DENV NS1 antigen; of these; 5 were also anti-DENV IgM + IgG + ; 7 were DENV IgM + IgG - , 2 were IgM - IgG + , and 7 were IgM - IgG - by specific ELISAs. Seven of the 21 NS1+ sera were RNA+ by RT-PCR (six DENV2, one DENV3), suggesting that DENV2 was the dominant serotype in our cohort. Whole-genome sequencing of two DENV2 isolates showed similarity with strains circulating in Singapore in 2016, and the envelope genes were also similar to strains circulating in India in 2017. DENV-neutralizing antibodies (nAbs) were present in 31 of 47 sera tested (66%); among these, 20, 24, 26, and 12 sera contained nAbs against DENV1, 2, 3, and 4 serotypes, respectively. Serology analysis suggested that 12 (26%) and 19 (40%) of the 49 subjects were experiencing primary and secondary DENV infections, respectively. Collectively, our results provide evidence for current and/or past exposure to multiple DENV serotypes in our cohort, and the RNA analyses further indicate that DENV2 was the likely dominant serotype circulating in Nepal in 2017. These data suggest that expanded local surveillance of circulating DENV genotypes and population immunity will be important to effectively manage and mitigate future dengue outbreaks in Nepal.

Sentinel Lymph Node Biopsy after Neoadjuvant Chemotherapy in Breast Cancer Patients with Positive Nodes Using Low-Cost Dual Dye Technique: Identifying Factors Associated with Adequate False Negative Rate Threshold.

Background: In this study, we evaluated the feasibility of the sentinel lymph node (SLN) identification rate (SLN-IR) of fluorescein-guided sentinel lymph node biopsy (SLNB) in combination with methylene blue dye (MBD) and factors which can lead to a false negative rate (FNR) threshold of 10%. Methods: This was a prospective cross-sectional non-randomized validation study in patients with post-neoadjuvant chemotherapy (NACT) clinically node negative axilla who were node positive prior to start of NACT. Patients underwent validation of SLNB using fluorescein (and blue LED light) and MBD. Axillary dissection was performed irrespective of SLNB histology. SLIN-IR and FNR were assessed and compared with various molecular subtypes. Results: The SLNs were identified in 102 out of 120 (85%) post-NACT patients. The median number of sentinel lymph nodes identified was 2 (range 1-3). The SLN-IR using MBD was 85%, FD was 82.5%, and combined MBD FD was 85%. Two or more SLNs were removed in 72 patients and 11 patients had tumor in the rest of the axilla, resulting in an FNR of 17.4%. An FNR was 25% in case only one SLN was found, and it was 11.42% if two or more than two SLNs were excised. Conclusions: This cohort study found that use of low-cost dual dyes in patients with positive axillary disease, rendered cN0 with NACT, with 2 or more negative SLNs with SLNB alone, results in an FNR of 11.4%. Her 2 positive and TNBC with 2 or more negative SLNs are associated with an FNR of <10%. However, the number of such patients was small and further studies with larger sample size are warranted to confirm these findings.

A systematic review and meta-analysis of diagnostic performance of fluorescein-guided sentinel lymph node biopsy in early breast cancer.

BACKGROUND: Evaluation of axillary lymph nodes status in cN0 axilla is performed by sentinel lymph node biopsy (SLNB) utilizing a combination of radioactive isotope and blue dye or alternative to isotope like Indocyanine green (ICG). Both are very resource-intensive; which has prompted development of low-cost technique of Fluorescein Sodium (FS)-guided SLNB. This systematic review and meta-analysis evaluate the diagnostic performance of FS-guided SLNB in early breast cancer. OBJECTIVES: The objective was to evaluate the diagnostic performance of FS for sentinel lymph node biopsy. METHODS: Eligibility criteria: Studies where SLNB was performed using FS. INFORMATION SOURCES: PubMed, EMBASE, Cochrane library and online clinical trial registers. Risk of bias: Articles were assessed for risk of bias using the QUADAS-2 tool. SYNTHESIS OF RESULTS: The main summary measures were pooled Sentinel Lymph Node Identification Rate (SLN-IR) and pooled False Negative Rate (FNR) using random-effects model. RESULTS: A total of 45 articles were retrieved by the initial systematic search. 7 out of the 45 studies comprising a total of 332 patients were included in the meta-analysis. The pooled SLN-IR was 93.2% (95% confidence interval [CI], 0.87-0.97; 87% to 97%). Five validation studies were included for pooling the false negative rate and included a total of 211 patients. The pooled FNR was 5.6% (95% confidence interval [CI], 2.9-9.07). CONCLUSION: Fluorescein-guided SLNB is a viable option for detection of lymph node metastases in clinically node negative patients with early breast cancer. It achieves a high pooled Sentinel Lymph Node Identification Rate (SLN-IR) of 93% with a false negative rate of 5.6% for the detection of axillary lymph node metastasis.

A comparison of swallowing related quality of life in patients undergoing transoral endoscopic versus open thyroid surgery.

INTRODUCTION: It is important for the endoscopic thyroid surgeon to understand the pros and cons of trans-oral endoscopic thyroidectomy-vestibular approach (TOETVA) vis-à-vis, open conventional thyroidectomy (OTx) so he/she can help patients in making informed choices regarding the type of procedure to opt for. Swallowing related quality of life (SWAL-QoL) has not been compared between the two approaches. Using a rigorous qualitative methodology and validated reliable tool, this study set out to compare the swallowing related quality of life in patients undergoing TOETVA versus OTx. METHODS: Prospective study at 3 time points in patients planned for hemithyroidectomy (Preoperative, 1 week and 12 weeks). Data were collected on patients at a tertiary teaching institute in India. Participants ranged from age 18-60 years with a diagnosis of benign euthyroid nodule undergoing hemithyroidectomy. Exclusion criteria were-(1) pre-existing vocal cord abnormalities, (2) undergoing surgery for recurrent nodules, and (3) any neuro-muscular disease affecting swallowing ability. Main outcome measure was comparison of swallowing related quality of life domain scores between patients undergoing hemithyroidectomy via either endoscopic trans-oral or open approach. RESULTS: Of the 82 included patients, 40 underwent TOETVA and 42 OTx. Both the groups were comparable in terms of demographic and clinicopathological profile. The mean preoperative SWAL-QOL scores were comparable in all domains. Mean SWAL-QoL scores for all domains on postoperative day 7 were significantly better in TOETVA group with domains burden, eating desire, mental health and communication having medium effect sizes. Physical symptom domain was better in the OTx group but had a small effect size. The difference in SWAL-QoL domains between the two groups persisted for 3 months also. CONCLUSION: Swallowing related quality of life after trans-oral endoscopic thyroidectomy compared to conventional open surgery has not been reported in the literature. Our findings suggest that trans-oral endoscopic thyroidectomy results in significant superior swallowing related quality of life in the majority of domains.

Low cost smart phone based laryngoscopy for the assessment of vocal cords in patients undergoing thyroid surgery: A pilot study.

Can a smart phone application be reliably used for laryngoscopy? This thesis was tested for peri-operative evaluation of vocal cords in patients undergoing thyroid and parathyroid surgery.

Effect of chewing gum in reducing postoperative ileus after gastroduodenal perforation peritonitis surgery: A prospective randomised controlled trial.

Chewing gum reduces the duration of postoperative ileus and early recovery of bowel function following elective abdominal surgery. However, its role has not been studied in cases of gastroduodenal perforation peritonitis, prompting us to conduct this study. Patients were randomised into two groups, 39 patients received chewing gum (study group) and 43 patients were in the control group. Sensation of hunger, appearance of first bowel sound, and passages of flatus and faeces were significantly early in the study group; their hospital stay was also shorter. Chewing gum reduces the duration of postoperative ileus in cases of gastroduodenal perforation peritonitis.Registration number: IEC/2020-23/3359 dated 13 December 2020, Institutional Ethics Committee, Netaji Subhash Chandra Bose Medical College, Jabalpur, India.

Functional Outcome of Arthroscopic Suture Pull-Out Fixation in Tibial Spine Avulsion of Anterior Cruciate Ligament.

BACKGROUND: Tibial spine avulsion of the anterior cruciate ligament is a rare intraarticular injury of the knee. In this condition, the tibial attachment site of the anterior cruciate ligament is detached from the knee. The mechanism of the injury is hyperextension of the knee and rotation with valgus force. There are so many treatment options. This study aims to find out the functional outcome of Arthroscopic Suture pull-out fixation in this injury. METHODS: This is a retrospective study done from August 15, 2019, to August 14, 2022. The outcome was analyzed by comparing the preoperative and 12-month postoperative International Knee Documentation Committee Score, Tegner Lysholm Score, Knee Range of motion, and Visual Analog Scale Score. RESULTS: Twenty-two patients were included with a mean age of 18.95 (13-31). Among them 15(68.2%) were male and 7(31.8%) were female. Arthroscopic suture pull-out fixation was done in all the cases. The knee range of motion was improved from preoperatively 35.00±7.86 to 135.68±3.50 at the final follow-up. The Tegner Lysholm score was improved from preoperatively 34.68±1.28 to 94.54±2.97 at the final follow-up. Preoperatively the VAS score was 8.04±1.27 which improved to 0.60±0.50 at the final follow-up. The IKDC score was 23.86±1.42 preoperatively which improved to 92.72±3.28 at the final follow-up with p-value < 0.001 Conclusions: Arthroscopic Suture pull-out fixation of tibial spine avulsion of the Anterior cruciate ligament is a good technique that restores the functions of the knee and has an excellent outcome Keywords: Anterior cruciate ligament; suture pull-out fixation; tibial spine avulsion.

Double blind randomized controlled trial of efficacy of ormeloxifene for the treatment of fibroadenoma (The FIBROCENT study).

BACKGROUND: We evaluated the effectiveness of Ormeloxifene (Centchroman) on regression of Fibroadenoma in a double-blind randomized controlled trial. METHODS: Patients with biopsy proven Fibroadenoma were enrolled between March 2023 and October 2023 and divided in two arms- Ormeloxifene group and Placebo group. Effectiveness of the treatment was evaluated using USG. No residual mass was defined as complete regression and more than 30% decrease in size was considered as partial regression. RESULTS: A total of 130 consecutive patients with Fibroadenoma were randomized to Ormeloxifene group (n = 65) and Placebo Group (n = 65). Complete regression was observed in 9% (6/65) patients in Ormeloxifene group and 10.8% (7/65) in Placebo Group at the end of 12 weeks (p = 0.49). Twenty one patients taking Ormeloxifene reported adverse events as compared to none in the other group. CONCLUSION: In our study Ormeloxifene was not found to be effective in treatment of fibroadenoma and had concerning side effects.

Low-Cost Radio-Opaque Tumor Marking Techniques for Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy: a Systematic Review.

Current standard of care localization techniques used in breast conserving surgery (BCS) after neoadjuvant chemotherapy (NACT) are expensive and may not be available in LMICs (lower-middle income countries). This review evaluated the efficacy of radio-opaque low-cost tumor markers. A systematic search was conducted as per PRISMA guidelines through November 30, 2022, for all studies using non-commercial radio-opaque tumor markers for patients undergoing BCS post NACT. Rate of unsatisfactory margin on final histology was the primary outcome. Oxford Centre for Evidence Based Medicine (OCEBM) levels were used to assess internal validity. After screening, 07 studies were included for data synthesis. For marking, four studies used LIGA clips, two used 5-mm cut pieces of K-wire, and one used cut pieces of 25-G needle. Incidence of unsatisfactory margins (positive/close) ranged from 0 to 11%. All studies found these low-cost markers to be feasible, with 100% pre-surgery visibility and 100% retrieval rate. Low-cost radio-opaque tumor markers (LIGA clips, 5-mm cut pieces of K-wire and 25-G needle) are effective methods of tumor localization especially for LMICs.

MicroRNA-29b-3p degenerates terminally differentiated dopaminergic SH-SY5Y cells by perturbation of mitochondrial functions.

Mitochondrial dysfunction is the main cause of gradual deterioration of structure and function of neuronal cells, eventually resulting in neurodegeneration. Studies have revealed a complex interrelationship between neurotoxicant exposure, mitochondrial dysfunction, and neurodegenerative diseases. Alteration in the expression of microRNAs (miRNAs) has also been linked with disruption in mitochondrial homeostasis and bioenergetics. In our recent research (Cellular and Molecular Neurobiology (2023) https://doi.org/10.1007/s10571-023-01362-4), we have identified miR-29b-3p as one of the most significantly up-regulated miRNAs in the blood of Parkinson's patients. The findings of the present study revealed that neurotoxicants of two different natures, that is, arsenic or rotenone, dramatically increased miR-29b-3p expression (18.63-fold and 12.85-fold, respectively) in differentiated dopaminergic SH-SY5Y cells. This dysregulation of miR-29b-3p intricately modulated mitochondrial morphology, induced oxidative stress, and perturbed mitochondrial membrane potential, collectively contributing to the degeneration of dopaminergic cells. Additionally, using assays for mitochondrial bioenergetics in live and differentiated SH-SY5Y cells, a reduction in oxygen consumption rate (OCR), maximal respiration, basal respiration, and non-mitochondrial respiration was observed in cells transfected with mimics of miR-29b-3p. Inhibition of miR-29b-3p by transfecting inhibitor of miR-29b-3p prior to exposure to neurotoxicants significantly restored OCR and other respiration parameters. Furthermore, we observed that induction of miR-29b-3p activates neuronal apoptosis via sirtuin-1(SIRT-1)/YinYang-1(YY-1)/peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1α)-regulated Bcl-2 interacting protein 3-like-dependent mechanism. Collectively, our studies have shown the role of miR-29b-3p in dysregulation of mitochondrial bioenergetics during degeneration of dopaminergic neurons via regulating SIRT-1/YY-1/PGC-1α axis.

Clinical outcomes associated with antidepressant use in inflammatory bowel disease patients and a matched control cohort.

Antidepressant medications (AMs) are frequently used in inflammatory bowel disease (IBD). Many AMs enhance serotonin (5-HT) availability, but this phenomenon may actually worsen IBD. We hypothesized that use of 5-HT-enhancing AMs would be associated with poor clinical outcomes in these disorders. We performed a retrospective cohort study using the Merative Health Marketscan® commercial claims database between 1/1/05 and 12/31/14. Participants (18-63 years) were either controls or had ≥ 2 ICD-9 diagnoses for IBD with ≥ 1 year of continuous insurance enrollment before index diagnosis and 2 years after. We identified new AM prescriptions using the medication possession ratio. Primary outcomes were corticosteroid use (IBD-only), IBD-related complication (IBD-only), IBD-related surgery (IBD-only), hospitalization, and emergency department (ED) visit(s) within 2 years of diagnosis or starting AM. We calculated adjusted hazard ratios (aHRs) in IBD AM users (for each outcome). We also performed subgroup analyses considering IBD and AM subtype. In the IBD cohort (n = 29,393, 41.4% female; 42.2%CD), 5.2% used AMs. In IBD, AM use was independently associated with corticosteroid use, ED visits, and hospitalizations, but not IBD-related complications. AM use was associated with a decreased risk of surgery. In the control cohort (n = 29,393, 41.4% female), AM use was also independently associated with ED visits and hospitalizations, and there was an increased likelihood of these two outcomes compared to the IBD cohort. In conclusion, while AM use was independently associated with an increased risk of ED visits and hospitalization in IBD, these risks were statistically more common in a matched control cohort. Additionally, AM use was associated with reduced risk of surgery in IBD, demonstrating a potential protective role in this setting.

Hookworm infestation as a rare cause of melaena in tropics: A case report.

Melaena due to hookworm infestation is a rare clinical presentation. It usually presents with symptoms of iron-deficiency anaemia owing to slow blood loss. Here we present a case of 45-year male who presented with a one-year history of intermittent melena requiring multiple blood transfusions. Preliminary endoscopies at different centres were normal. The presence of hookworm in the duodenum was only detected on repeat upper endoscopy as the cause of blood loss, and treatment with albendazole was successful in curing the patient.
