Abstract
This study was aimed at exploring the causes of relaparotomy following caesarean section. The surgical procedures performed during relaparotomy were also discussed. This was a prospective study conducted in the Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from November 2020 to May 2021. MMCH is the largest referral Hospital in Mymensingh. During this study period 48 puerpera needed relaparotomy after caesarean section within 6 weeks of caesarean section. The frequency of relaparotomy was 2.6%. Of the 48 cases, 28(58.33%) cases needed relaparotomy due to post partum haemorrhage (PPH). Among them 9(18.75%) had primary PPH, 19(39.58%) patients had secondary PPH. Here 7(14.58%) patients suffered from sub rectus hematoma, 5(10.42%) patients had puerperal sepsis, 3(6.23%) had internal haemorrhage and 4(8.33%) women had wound dehiscence. Foreign body was removed in 1 case (2.08%). Main procedure performed was subtotal (45.83%) and total hysterectomy (25%). Coagulation failure and septicaemia were causes of maternal death. Case fatality rate was 4.17%. Obstetric patients who need relaparotomy face potential death. This study will help us to identify the causes for relaparotomy. Due precautions should be taken as far as possible to avoid this complications following caesarean section and thereby reduce maternal mortality and morbidity.

Abstract
Sudden sensorineural hearing loss can be a frightening experience for the sufferer and needs immediate treatment. Systemic steroid therapy has been the mainstay of treatment of this condition but concerns about their side effects has led to their use by intratympanic injection. We studied the results of intratympanic dexamethasone (IT-Dexa) both as a primary therapy and as salvage treatment after failure of oral steroids. A total of 39 patients of SSNHL were studied prospectively. Of these 23 were given oral steroids. Ten of these showed no response and were treated with IT-Dexa 4 mg/ml twice a week for two weeks. In addition, 16 patients who reported later than two weeks or had concomitant medical disorders like diabetes and/or hypertension were treated with IT-Dexa. While oral steroids showed hearing improvement (≥ 10 dB) in 56.5% patients, the recovery rate was 62.5% and 80% in those treated primarily with IT-Dexa and as salvage therapy respectively. There was a negative correlation of delay in institution of treatment with hearing recovery. Conclusion: intratympanic dexamethasone is a safe and effective treatment and should be offered to patients as a primary treatment modality and also as salvage therapy after failure of oral steroids. For best results the treatment should be started at the earliest.

Abstract
Background The need for cardiac intensive care unit (ICU) beds remains high in order to monitor and treat emergency patients with severe cardiovascular diseases, particularly during the COVID-19 pandemic. Therefore, timely discharge strategies from the cardiac ICU to peripheral wards are crucial to meet the increasing demand for cardiac ICU beds. Early patient transfer from ICU to the peripheral ward may result in worsening of the patient's clinical condition and outcome with readmission to the ICU, while late transfer may require prolonged expert care and generate unwanted costs. Purpose To investigate whether unplanned readmission of cardiac patients to the cardiac ICU within 72 hours after the index ICU stay is associated with increased mortality risk (primary outcome) and prolonged total hospital length of stay (LOS) (secondary outcome), as well as to identify predictors of ICU readmission in cardiac patients. Methods Adult patients who were admitted to the cardiac ICU due to a primary cardiac admission diagnosis at a tertiary care center between 2003 and 2021 were included. Outcomes were analysed with multivariable regression models adjusted for 26 a priori defined variables on patient demographics, underlying comorbidity levels, ICU procedures and administered ICU drugs. Results 30,942 cardiac patients were included, out of whom 1,499 patients (4.84%) were readmitted to the cardiac ICU within 72 hours. 1,023 (68.2%) of readmitted patients were male. Compared to non-readmitted patients, readmitted patients were older, had more underlying comorbidities (Charlson Index), had more severe disease courses (SOFA score, TISS, APACHE II score and SAPS), as well as required more frequently vasopressor therapy, renal replacement therapy and coronary angiographies (Table 1). Readmission to the cardiac ICU was associated with higher in-hospital mortality risk (Odds Ratio 7.52, 95% Confidence Interval (CI) 4.15–12.27, P<0.001) and prolonged hospital LOS (Incidence Rate Ratio 1.56, 95% CI 1.15–1.58, P<0.001). Patients who were readmitted to the ICU had been discharged 18% earlier during the index ICU stay compared to non-readmitted patients (P<0.001). Of note, readmitted and non-readmitted patients had similar vital parameters at time of ICU discharge after their index ICU stay. During the index ICU stay, non-readmitted patients were prescribed more beta blockers (65.3% vs. 45.8%), ACE inhibitors (37.0% vs. 27.2%) and blood transfusions (10.7% vs. 7.7%). Conclusion Early readmission to the cardiac ICU was associated with increased in-hospital mortality and prolonged hospitalisation. Readmitted patients had been discharged earlier from their index ICU stay and required more comprehensive critical care. ICU discharge strategies should optimally be based on objective patient assessments to facilitate patient safety and shorten hospital length of stay. Artificial intelligence-based algorithms may support clinicians with safe ICU discharge. Funding Acknowledgement Type of funding sources: None.

Abstract
Indigenous Peoples experience disproportionately higher rates of problematic substance use. These problems are situated in a context of individual and intergenerational trauma from colonization, residential schools, and racist and discriminatory practices, policies, and services. Therefore, substance use interventions need to adopt a trauma-informed approach. We aimed to synthesize and report the current literature exploring the intersection of trauma and substance use interventions for Indigenous Peoples. Fourteen databases were searched using keywords for Indigenous Peoples, trauma, and substance use. Of the 1373 sources identified, 117 met inclusion criteria. Literature on trauma and substance use with Indigenous Peoples has increased in the last 5 years (2012-2016, n = 29; 2017-2021, n = 48), with most literature coming from the United States and Canada and focusing on historical or intergenerational trauma. Few articles focused on intersectional identities such as 2SLGBTQIA+ (n = 4), and none focused on veterans. There were limited sources (n = 25) that reported specific interventions at the intersection of trauma and substance use. These sources advocate for multi-faceted, trauma-informed, and culturally safe interventions for use with Indigenous Peoples. This scoping review illuminates gaps in the literature and highlights a need for research reporting on trauma-informed interventions for substance use with Indigenous Peoples.

Abstract
OBJECTIVE To investigate quality of life (QoL) and association with surgical complexity and disease burden after surgical resection for advanced ovarian cancer in centres with variation in surgical approach DESIGN: Prospective multicentre observational study SETTING: United Kingdom, Kolkata, India, and Melbourne, Australia gynaecological cancer surgery centres. PARTICIPANTS Patients undergoing surgical resection for late stage ovarian cancer. Exposure Low, intermediate or high Surgical Complexity Score (SCS) surgery MAIN OUTCOMES AND MEASURES: Primary: EORTC-QLQ-C30 Global score change. Secondary: EORTC OV28, progression free survival. RESULTS Patients' pre-operative disease burden and SCS varied between centres, confirming differences in surgical ethos. QoL response rates were 90% up to 18 months. Mean change from the pre-surgical baseline in the EORTC QLQ-C30 was 3.4 (SD 1.8, n=88) in the low, 4.0 (SD 2.1, n=55) in the intermediate and 4.3 (SD 2.1, n=52) in the high SCS group after 6 weeks (p=0.048) and 4.3 (SD 2.1, n=51), 5.1 (SD 2.2, n=41) and 5.1 (SD 2.2, n=35) respectively after 12 months (p=0.133). In a repeated measures model, there were no clinically or statistically meaningful differences in EORTC QLQ-C30 global scores between the three SCS groups, p= 0.840 but there was a small statistically significant improvement in all groups over time (p<0.001). The high SCS group experienced small to moderate decreases in physical (p=0.004), role (p=0.016) and emotional (p=0.001) function at 6 weeks post-surgery which resolved by 6-12 months. CONCLUSIONS AND RELEVANCE Global QoL of patients undergoing low, intermediate, and high SCS surgery improved at 12 months post operation and was no worse in patients undergoing extensive surgery.

Abstract
We perform two-dimensional Fourier transform spectroscopy on magneto-excitons in GaAs at magnetic fields and observe Zeeman splitting of the excitons. The Zeeman components are clearly resolved as separate peaks due to the two-dimensional nature of the spectra, leading to a more accurate measurement of the Zeeman splitting and the Landé g factors. Quantum coherent coupling between Zeeman components is observed using polarization dependent one-quantum two-dimensional spectroscopy. We use two-quantum two-dimensional spectroscopy to investigate higher four-particle correlations at high magnetic fields and reveal the role of the Zeeman splitting on the two-quantum transitions. The experimental two-dimensional spectra are simulated using the optical Bloch equations, where many-body effects are included phenomenologically.

Abstract
We apply Linear Prediction from Singular Value Decomposition (LPSVD) to two-dimensional complex optical data in the time-domain to generate spectra with advantages over discrete Fourier transformation (DFT). LPSVD is a non-iterative procedure that fits time-domain complex data to the sum of damped sinusoids, or Lorentzian peaks in the spectral domain. Because the fitting is linear, it is not necessary to give initial guess parameters as in nonlinear fits. Although LPSVD is a one-dimensional algorithm, it can be performed column-wise on two-dimensional data. The method has been extensively used in 2D NMR spectroscopy, where spectral peaks are typically nearly ideal Lorentzians, but to our knowledge has not been applied in the analogous optical technique, where peaks can be far from Lorentzian. We apply LPSVD to the analysis of zero, one, and two quantum electronic two-dimensional spectra from a semiconductor microcavity. The spectra consist of non-ideal, often overlapping peaks. We find that LPSVD achieves a very good fit even on non-ideal data. It reduces noise and eliminates discrete distortions inherent in the DFT. We also use it to isolate and analyze weak features of interest.

Abstract
Abstract
Background
Cardiac tamponade is a potentially life-threatening complication of pericardial effusion. Pericardiocentesis with drainage is the mainstay of treatment for patients with pericardial effusion and cardiac tamponade. Percutaneous balloon pericardiotomy (PBP) is an adjunct to pericardiocentesis that may alleviate the risk for recurrent effusion and repeat procedures. However, the efficacy of PBP plus pericardiocentesis compared to pericardiocentesis alone is not clear.
Purpose
We sought to determine whether PBP plus pericardiocentesis was associated with less recurrence of pericardial effusion than pericardiocentesis alone.
Methods
We conducted a single-centre retrospective analysis of patients ≥18 years old with non-iatrogenic pericardial effusion undergoing either pericardiocentesis alone or PBP plus pericardiocentesis for the first time. For PBP, a balloon was advanced over a guidewire until it crossed the pericardium and was then inflated until the balloon profile was fully expanded. Type of balloon used, and single or double balloon technique were left up to the operator. Recurrent pericardial effusion was defined as a large pericardial effusion on echocardiogram, pericardial effusion that caused hemodynamic compromise, or pericardial effusion that necessitated another intervention to drain at any time after initial procedure. Risk factors for recurrent pericardial effusion were also assessed.
Results
There were 208 patients who underwent pericardiocentesis, with 33 patients receiving PBP plus pericardiocentesis. In all patients, the rate of recurrent pericardial effusion was 15.9% and 15.2%, respectively (p=0.92). In patients with a cancer diagnosis at time of procedure, the rate of recurrent pericardial effusion was 17.8% and 16.7%, respectively (p=0.89). In patients with malignant pericardial effusion as confirmed by cytology, the rate of recurrent pericardial effusion was 20.4% and 13.3%, respectively (p=0.72). Patients with a connective tissue disease (CTD) had an increased odds ratio (OR) of recurrent pericardial effusion when compared to patients without a CTD (OR 3.19, 95% CI 1.31–7.77).
Conclusions
The results of this study suggest that PBP plus pericardiocentesis offers no significant benefit over pericardiocentesis alone at preventing recurrent pericardial effusion. This finding was true in all sub-groups, including patients with cancer and patients with malignant pericardial effusion. Patients with a CTD were three times more likely than patients without a CTD of having a recurrent pericardial effusion, independent of treatment strategy.

Abstract
UNLABELLED This study from southern India showed that the trabecular microarchitecture and proximal hip geometry were significantly impaired in postmenopausal women with diabetes as compared to age and BMI matched non-diabetic controls. This is despite there being no significant difference in bone mineral density at the femoral neck and hip not between both groups. One-third of the study subjects with type 2 diabetes had prevalent vertebral fractures. Bone mineral density assessment as a standalone tool may not adequately reflect bone health in subjects with diabetes. INTRODUCTION There is limited information with regard to bone health in Indian postmenopausal women with type 2 diabetes. We studied the bone mineral density (BMD), trabecular bone score (TBS), prevalent vertebral fractures (VF), proximal hip geometry, and bone mineral biochemistry in ambulatory postmenopausal women with and without type 2 diabetes mellitus (T2DM). METHODS This was a cross-sectional study conducted at a tertiary care center. BMD, TBS, prevalent vertebral fractures, and hip structural analysis (HSA) were assessed using a dual-energy X-ray absorptiometry (DXA) scanner. Bone mineral biochemical profiles were also studied. RESULTS A total of 202 ambulatory postmenopausal women known to have type 2 diabetes mellitus with mean (SD) age of 65.6 (5.2) years and 200 age and BMI matched non-diabetic controls with mean (SD) age of 64.9 (4.7) years were recruited from the local community. Although the prevalence of lumbar spine osteoporosis was significantly lower among cases (30.7%) as compared to controls (42.9%), the prevalence of degraded bone microarchitecture (TBS < 1.200) was significantly higher among cases (51%) than in controls (23.5%); P < 0.001. Prevalent vertebral fractures were not significantly different in cases and controls. The various geometric indices of the proximal hip were significantly impaired in subjects with diabetes as compared to controls. CONCLUSION This study may highlight the utility of the trabecular bone score and hip structural analysis in subjects with diabetes, where the bone mineral density tends to be paradoxically high, and may not adequately predict fracture risk.

Abstract
The present study examined the seasonal cycling of phosphorous (P) along the southwest coast of India (SWCI) based on two cruises during the southwest monsoon (SWM) and northeast monsoon (NEM) of 2018. During SWM, the entire SWCI experienced intense upwelling manifested by the incursion of cold, nutrient-rich, and hypoxic waters. During NEM, the region was transformed into a warm, well-oxygenated and nutrient-deplete environment. Dissolved inorganic phosphorus (DIP) was significantly high in the subsurface during SWM due to its release from sediments. The sediment P was high and showed an increasing trend towards the south, principally dependent on the sediment texture, organic carbon, and Fe concentrations. Bioavailable P, the sum of exchangeable (PEx) and reducible (PFe) fractions, was almost consistent (5-20%) over seasons, though PFe showed a marked reduction during SWM. Authigenic fraction (PAut) was the most dominant (46%), followed by detrital (PDet 41%) and residual (PRes 8%) fractions. Principal component analysis (PCA) of geochemical parameters for SWM was indicative of the high dissolution of Fe (oxy)hydroxides under hypoxia releasing P and its complexation with organic matter and Fe. PCA results for the NEM were different, as it indicated increased preservation of P-associated organic matter and Fe, alternately favouring the formation of PAut in sediments. The study's significance is the observation that the bottom water oxygen concentration can significantly influence sedimentary P cycling in tropical coastal upwelling zones.

Abstract
Transparent conductive oxides such as indium tin oxide (ITO) bear the potential to deliver efficient all-optical functionality due to their record-breaking optical nonlinearity at epsilon near zero (ENZ) wavelengths. All-optical applications generally involve more than one beam, but, to our knowledge, the coherent interaction between beams has not previously been discussed in these materials, which have a hot electron nonlinearity. Here we study the optical nonlinearity at ENZ in ITO and show that spatial and temporal interference has important consequences in a two-beam geometry. Our pump-probe results reveal a polarization-dependent transient that is explained by diffraction of pump light into the probe direction by a temperature grating produced by pump-probe interference. We further show that this effect allows tailoring the nonlinearity by tuning the frequency or chirp. Having fine control over the strong and ultrafast ENZ nonlinearity may enable applications in all-optical neural networks, nanophotonics, and spectroscopy.

Abstract
Introduction: Chronic subdural haematomas are one among common neurosurgical emergencies especially affecting elderly male. Usually, presents with subacute Cerebro Vascular Accident (CVA), impaired higher mental function and sometimes with reversible dementia. Rarely, it presents with end stage herniation. Burr Hole Drainage (BHD) is the most popular and worldwide procedure of choice and it successfully address the problem in majority of cases. However, in a small group of patients it needs a wider craniotomy to deal with the subdural membrane which is mainly associated with recurrence of the entity. Aim: To evaluate the comparative incidence of various clinical presentation and analysing the outcome of different treatment modalities in different subgroups of patients with chronic subdural haemorrhage with respect to complication and survivality. Materials and Methods: This retrospective study enrolled data of 100 consecutive patients of subacute (n=30) and chronic subdural haematoma (n=70) who were admitted and undergone neurosurgical management of Veer Surendra Sai Institute of Medical Science and Research (VIMSAR), Burla, Odisha between September 2018 to September 2020. Variables were collected from patient’s records at discharge and analysed with respect to spectrum of clinical presentation and surgical outcome of different treatment modalities and problems associated with it. Results: The mean age group was 57.39 years and headache was the most common clinical presentation in the present study (86%) followed by hemiparasis (74%). BHD was carried out in 94 patients (94%). Primary craniotomy and membrane excision was carried out in 5 patients. Secondary craniotomy was performed in 1 patient after early re-accumulation and clinical deterioration. The outcome was assessed utilising Glasgow outcome scale with total five deaths in the series. Conclusion: Chronic Subdural Haemorrhage (CSDH) a problem of late adulthood (5th to 6th decade) which mostly follows two to three weeks after trauma. It needs proper preoperative assessment and requires timely intervention with skilled nursing care for early recovery. Post-traumatic subacute subdural haematoma in young subject and alcoholics needs special attention during course of their treatment. Bilateral puppilary failure, low Glasgow Coma Scale (GCS) and seizure association are risk factors for poor outcome.

Abstract
Placenta is the mirror of maternal and fetal status; it reflects the changes due to complications in pregnancy of mother. The growth and survival of the fetus in utero is directly related to formation, development and maturation of the placenta. Placental index was correlated to poor pregnancy outcomes. Placental index can help to identify fetal growth restriction which is result of placental insufficiency and is characterized by insufficient trasnsplacental transport of nutrients and oxygen. This cross sectional descriptive study would provide information about the ratio of placental index in different gestational age group in Bangladeshi women. To achieve this aim the study was performed on 60 human placenta and corresponding fetuses and gestational age (in weeks) categorized as Group A (28-32), Group B (33-37), Group C (38-40). These sample and information were collected from normal pregnancy in Gynecology and Obstetrics Department of Mymensingh Medical College Hospital from July 2009 to June 2010. After preservation in 10% formal saline, study was done in Department of Anatomy in Mymensingh Medical College. In this study, the mean±SD placental index was in Group A (0.187±0.113), Group B (0.153±0.025) and Group C (0.166±0.025) and also observed that mean placental index decreased with age up to certain level then increase in Group C. The mean placental index was maximum in Group A (0.187±0.113) and was minimum in Group B (0.153±0.025). The mean difference of placental index between Groups A&B, A&C and B&C was statistically not significant. Observed findings of this study were compared with those of Western and Bangladeshi researches.

Abstract
The tyrosine phosphatase SHP2 controls the activity of pivotal signaling pathways, including MAPK, JAK-STAT, and PI3K-Akt. Aberrant SHP2 activity leads to uncontrolled cell proliferation, tumorigenesis, and metastasis. SHP2 signaling was recently linked to drug resistance against cancer medications such as MEK and BRAF inhibitors. In this work, we present the development of a novel class of azaindole SHP2 inhibitors. We applied scaffold hopping and bioisosteric replacement concepts to eliminate unwanted structural motifs and to improve the inhibitor characteristics of the previously reported pyrazolone SHP2 inhibitors. The most potent azaindole 45 inhibits SHP2 with an IC50 = 0.031 μM in an enzymatic assay and with an IC50 = 2.6 μM in human pancreas cells (HPAF-II). Evaluation in a series of cellular assays for metastasis and drug resistance demonstrated efficient SHP2 blockade. Finally, 45 inhibited proliferation of two cancer cell lines that are resistant to cancer drugs and diminished ERK signaling.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) ruptures are of major concern in sports. As mostly young and active individuals are affected there is an emphasis on the rapid and safe return to sports (RTS). Strengthening the ventral and dorsal thigh muscles is a prerequisite for a successful RTS after ACL reconstruction (ACLR), as persistent muscle weakness may increase the incidence for secondary injuries and impair performance. Aiming to increase evidence on the importance of preoperative muscle strength and the coaching of patients, the purpose of this study is to compare thigh muscle strength pre- and post-operatively after ACLR. METHODS We performed a retrospective analysis of 80 patients with primary, isolated ACLR using a four-stranded hamstring autograft. We performed bilateral isokinetic concentric strength measurement (60°/s) before and six months after ACLR. Primary outcomes were the maximal knee extension and flexion torque, hamstrings-to-quadriceps ratio (H/Q ratio) and the corresponding limb symmetry indices (LSI). Pearson correlations were calculated for pre- and post-surgical values. RESULTS The operated as well as the unaffected leg increased maximal knee extension (+ 18% ± 7% p < 0.05; + 11% ± 5% p < 0.05) and flexion torque (+ 9% ± 5% p < 0.05, + 10% ± 6% p < 0.05) throughout the 6 months of rehabilitation. The H/Q ratio remained unaffected (- 2% ± 3% p = 0.93; - 4% ± 4% p = 0.27). LSI of knee extension strength increased significantly (6% ± 3% p < 0.05), while flexion strength remained unaffected (+ 2% ± 4% p = 0.27). Positive correlations underline the interrelationship between the strength pre- and post-surgery for the knee extension (r = 0.788 p < 0.05) and knee flexion strength (r = 0.637 p < 0.05) after ACLR. CONCLUSIONS Preoperative leg extension and flexion strength normalized to body mass are strongly correlated to postoperative strength performance after ACLR. Therefore, pre-operative quadriceps and hamstring muscle strength deficits may have a significant negative impact on functional performance following ACLR. This emphasizes the need for intensive preoperative screening and subsequent treatment to achieve the best possible preoperative leg strength before ACLR. TRIAL REGISTRATION DRKS00020210 .

Abstract
OBJECTIVES . To investigate the dose-response relationship between cardiovascular or psychotropic medication dosages and falling orthostatic blood pressure in geriatric inpatients. METHODS . This cross-sectional study included 100 consecutive geriatric inpatients of a Belgian hospital. The end points were the maximum changes of systolic (sBP) and diastolic (dBP) blood pressure in a standing up position at one or three minutes. The dosages of six classes of vascular and five classes of psychotropic medications were expressed in terms of a proportion of defined daily doses (DDD). Bivariate and multivariate linear regression models were used. RESULTS . The 100 geriatric patients (85 ± 5 years, 58 % women) received 7.7 ± 4 medications (mean DDD: vascular = 1.0, psychotropic = 0.74) on the day of an orthostatic test (lying sBP: 136 ± 21; dBP: 72 ± 14 mm Hg). In a standing position, sBP and dBP fell by 12 ± 17 and 11 ± 5 mmHg, respectively. At the individual level, BP change was not correlated with vascular DDD (sBP: p = 0.07, r2 = 0.04; dBP: p = 0.59; r2 = 0.004) nor with psychotropic DDD (sBP: p = 0.14, r2 = 0.02; dBP: p = 0.82; r2 = 0.0). In multivariate analysis, sBP drop was positively associated with age, diabetes, falls history, and number of medications, but not with the DDD of any of the medication classes, while dBP drop was positively associated with age, diabetes, stroke and anaemia, but again with the DDD of any of the medication classes. CONCLUSION . No correlation was found between vascular and psychotropic medication dosages and the orthostatic blood pressure drop expressed as a continuous variable.

Abstract
BACKGROUND Nocturia is common and associated with multiple disease states. Many potential mechanisms have been proposed for nocturia, which also remains challenging to manage. PURPOSE To use multivariate analysis to determine which combinations of factors can accurately discriminate clinically significant nocturia in patients to facilitate clinical management and treatment decisions. PATIENTS AND METHODS Data analysis was based on frequency volume charts from three randomized controlled trials. There were 1479 patients included, of which 215 patients had no/mild nocturia and 1264 had clinically significant nocturia with at least two voids per night. Factors studied that may influence nocturia were demographics, sleep duration, functional bladder capacity, 24 h urine volume and literature-suggested definitions of nocturnal polyuria. We used univariate analysis and cross-validated multivariate modelling to assess association between factors and nocturia status, redundancy between factors and whether the combined use of factors could explain patients' nocturia status. RESULTS The multivariate analyses showed that the most useful definitions of nocturia are 'Nocturia Index' (NI) and 'Nocturnal Urine Production per hour' (NUPh) in combination with functional bladder capacity and sleep duration. Published definitions providing binary nocturnal polyuria outcomes had lower performance than continuous indices. These analyses also showed that NI was not specific to nocturnal polyuria as it also captured nocturia due to low functional bladder capacity. By contrast, NUPh was demonstrated to be specific to nocturnal polyuria. CONCLUSION NUPh has previously been shown among elderly males to be essential in nocturia and a very valid measure of nocturnal polyuria. However, the current, large and independent dataset now confirms that it can be applied in an adult population with a complaint of nocturia covering both males and females.

Abstract
Chronic heavy metal exposure and the health hazards that ensue are important public-health problems. We highlight the occurrence of hypophosphataemic osteomalacia due to chronic cadmium exposure in the silver industry in India. Three silversmiths presented similarly with clinical, biochemical and radiological evidence of hypophosphataemic osteomalacia. Considering their occupation, their blood samples were screened for heavy metals and were found to have toxic levels of cadmium. They were initiated on neutral phosphate and calcitriol. On follow-up, they reported significant reduction in severity of symptoms. It is essential to maintain a high index of suspicion in diagnosing this condition. A thorough knowledge of the occupational background of patients, as well as ambient conditions at the workplace is of utmost importance in contemplating the possibility of such rare occurrences. Moreover, regulatory agencies and policy makers ought to survey the silver industry and ensure that the metals used are within permissible safe limits of exposure.

Abstract
INTRODUCTION The performance of tracheotomy is a common procedural request by critical care departments to the surgical services of general surgery, thoracic surgery and otolaryngology - head & neck surgery. A Canadian Society of Otolaryngology - Head & Neck Surgery (CSO-HNS) task force was convened with multi-specialty involvement from otolaryngology-head & neck surgery, general surgery, critical care and anesthesiology to develop a set of recommendations for the performance of tracheotomies during the COVID-19 pandemic. MAIN BODY The tracheotomy procedure is highly aerosol generating and directly exposes the entire surgical team to the viral aerosol plume and secretions, thereby increasing the risk of transmission to healthcare providers. As such, we believe extended endotracheal intubation should be the standard of care for the entire duration of ventilation in the vast majority of patients. Pre-operative COVID-19 testing is highly recommended for any non-emergent procedure. CONCLUSION The set of recommendations in this document highlight the importance of avoiding tracheotomy procedures in patients who are COVID-19 positive if at all possible. Recommendations for appropriate PPE and environment are made for COVID-19 positive, negative and unknown patients requiring consideration of tracheotomy. The safety of healthcare professionals who care for ill patients and who keep critical infrastructure operating is paramount.

Abstract
This cross sectional, study was carried out in the department of Obstetrics and Gynaecology in Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from October 2015 to September 2016. The objective of the study was to evaluate dyslipidaemia between natural and surgical menopausal women. Patients who attended the menopausal clinic of Mymensingh Medical College Hospital, Mymensingh were included in the study. For this purpose 91 patient were divided into study (n=46) and comparison (n=45) groups. Serum total cholesterol (TC), serum triglyceride (TG), Serum high density lipoprotein cholesterol (HDL-cholesterol) were estimated by colorometric method and serum low density lipoprotein cholesterol (LDL-cholesterol) was calculated by using Friedwald's formula. Age range of menopausal women was 45 to 60 years. The mean age with SD was in study group 50.26±2.57 years and control group 49.02±3.13 years. It was observed that women with surgical menopause had higher mean plasma level of total cholesterol with standard deviation 192.84±52.43mg/dl while that of mean and standard deviation of natural menopause 192.26±27.56mg/dl i.e. Mean difference was statistically insignificant (p>0.05). Mean plasma levels of Triglyceride (TG) with standard deviation (215.87±67.73mg/dl) higher in surgical menopause as compared with natural menopause (147.33±65.17mg/dl) which was statistically significant (p<0.001). There was significant rise of mean with standard deviation of HDL cholesterol in natural menopause was (44.42±8.14mg/dl) as compared to surgical menopause (34.61±8.55mg/dl) and the mean difference was statistically highly significant (p<0.001). Mean with standard deviation of plasma LDL cholesterol (122.02±49.16mg/dl) rise in surgical menopause as compared to physiological menopause (118.06±20.56mg/dl) and was statistically insignificant (p>0.05). Serum total cholesterol, serum triglyceride (TG) and serum low density lipoprotein (LDL) was found significant higher level in surgical menopause. And only serum high density lipoprotein (HDL) was found significantly higher level in physiological menopause. So, surgical menopausal women were marked dyslipidaemia.

Abstract
Biomarker-guided trials have drawn considerable attention as they promise to lead to improvements in the benefit-risk ratio of treatments and enhanced opportunities for drug development. A variety of such designs have been proposed in the literature, many of which have been adopted in practice. Implementing such trial designs in practice can be challenging, and identifying those challenges was the main objective of a workshop organised by the MRC Hubs for Trials Methodology Research Network's Stratified Medicine Working Group in March 2017. Participants reflected on completed and ongoing biomarker-guided trials to identify the practical challenges encountered. Here, the key challenges identified during the workshop including those related to funding, ethical and regulatory issues, recruitment, monitoring of samples and laboratories, biomarker assessment, and data sharing and resources, are discussed. Despite the complexities often associated with biomarker-guided trials, the workshop concluded that they can play an important role in advancing the field of personalised medicine. Therefore, it is important that the practical challenges surrounding their implementation are acknowledged and addressed.

Abstract
An experimental apparatus is described for multidimensional optical spectroscopy with fully automated polarization control, based on liquid crystal variable retarders. Polarization dependence of rephasing two-dimensional coherent spectra are measured in a single scan, with absolute phasing performed for all polarization configurations through a single automated auxiliary measurement at the beginning of the scan. A factor of three improvement in acquisition time is demonstrated, compared to the apparatus without automated polarization control. Results are presented for a GaAs quantum well sample and an InGaAs quantum well embedded in a microcavity.

Abstract
PURPOSE The main objective of our study was to determine which combination of modifiable and non-modifiable parameters that could discriminate patients with nocturia from those without nocturia. This was a post-hoc analysis of 3 prospective, observational studies conducted in Ghent University. Participants completed frequency volume chart (FVC) to compare characteristics between patients with and without nocturia. METHOD This was a post hoc analysis of three prospective, observational studies conducted in Ghent University. Participants completed frequency volume chart (FVC) to compare characteristics between adults with and without nocturia. Study 1: adults with and without nocturia (n = 148); Study 2: patients ≥65 years with and without nocturnal LUTS (n = 54); Study 3: menopausal women before and after hormone replacement therapy (n = 43). All eligible patients (n = 183) completed a FVC during 24 hours (n = 13), 48 hours (n = 30) or 72 hours (n = 140). The combination of algorithms and number of determinants obtaining the best average area under the receiver operating curve (AUC-ROC) led to the final model. Differences between groups were assessed using the AUC-ROC and Mann- Whitney-Wilcoxon tests. Holm corrections were applied for multiple statistical testing. Also, the stability of the feature selection was evaluated. RESULTS The best discrimination was obtained when 13 determinants were included. However, a logistic regression model based on seven determinants selected with random forest had comparable discrimination including an optimal signature stability. It was able to discriminate almost perfectly between nights with and without nocturia. CONCLUSION Relevant information to accomplish the excellent predictability of the model is; functional bladder capacity, 24 hours urine output, nocturnal output, age, BMI. The multivariate model used in this analysis provides new insights into combination therapy as it allows simulating the effect of different available treatment modalities and its combinations.

Abstract
Although nonoperative treatment is indicated & successful for the majority of diaphyseal humeral fractures, nonunion is not rare condition. The prevalence of nonunion as a complication of conservative treatment has been reported to be as high as 15%. Locking compression plate combined with autogenous cancellous bone grafting can result in reliable healing of these humeral nonunion with excellent functional outcome. This prospective observational study was conducted September, 2016 to October, 2018 at National Institute of Traumatulogy & Orthopaedic Rehablitation, Dhaka & Mymensingh Medical College, Mymensingh, Bangladesh. Fifteen (15) patients with non-united humeral shaft fractures were treated by open reduction and internal fixation by LCP with autogenous cancellous bone graft. Detailed clinical conditions of all patients, duration of injury, technical difficulty with the implant, hospital stay period were recorded. Follow up period was 6 months. The patients were evaluated clinically and radiologically for outcomes. The progresses of healing as well as occurrence of complications were recorded. The modified Constant and Murley score of functional assessment was used for shoulder & elbow function. Age of the study patients was ranged 20-50 years. Maximum patients were male 12. Mode of injury were found road traffic accident 8 cases, fall from height 5 cases. Right side was injured in 9 patients. Atrophic nonunion was found in 13 patients and hypertropic in 2 patients. The mean union time was 15 weeks. Only one patient had wound infection and 2 patients had shoulder stiffness. Functional outcome which constituted 90% satisfactory results in 13 cases according to modified Constant & Murley scoring system. Union rate was 100%. Therefore, LCP fixation with autogenous cancellous bone graft is a standard treatment method for nonunion of humeral shaft fracture.

Abstract
Distal third comminuted humerus shaft fractures are challenging injuries to treat because of complex anatomy and fracture patterns. Functional bracing, operative treatment with intramedullary nails or conventional plates also has limitation of inadequate fixation in the distal third comminuted humerus shaft fractures. Locking compression plate (LCP) has been introduced to overcome this problem. Our aim of this study was to assess the effectiveness of osteosynthesis of distal third comminuted humerus shaft fractures by LCP using posterior approach. This prospective observational study was conducted from July 2015 to June 2018 at Mymensingh Medical College Hospital (MMCH) and National Institute of Traumatulogy & Orthopaedic Rehablitation (NITOR), Dhaka, Bangladesh. Thirty three patients were operated on for comminuted fractures of distal third humerus. Two cases were excluded from the evaluation of final out come due to their discontinued follow up. Treatment included open reduction and LCP fixation by posterior mid line approach. The range of motion of the shoulder and elbow were evaluated according to the criteria by modified Constant and Murley scoring system. Union was achieved in all the patients after a mean of 17 weeks (range 12-24 weeks). Deep infection, nonunion, malunion, implant failure or permanent nerve injury did not occur in any of the patients. Three patients had transient radial nerve palsy. Four patients developed superficial infections. All patients were relieved pain postoperatively. Shoulder range of motion was excellent in 20 patients & elbow range of motion was excellent in 21 patients. Functional out come were excellent in 11 & good in 16 patients which constituted 87% satisfactory results. Treatment with open reduction and LCP fixation by posterior approach is a safe and effective option in distal third comminuted humeral fractures.

Abstract
Treatment of extra-articular distal humeral shaft fractures with plating techniques is often difficult. The recent development of LCP has improved the surgical treatment of fractures by overcoming the few drawbacks of older fixators. The aim of this prospective observational study was to assess the effectiveness of osteosynthesis of extra-articular diaphyseal fractures of the distal third of the humerus using a single locking compression plate (LCP) and was conducted from July 2016 to June 2018 at the National Institute of Traumatology and Orthopedic Rehabilitation (NITOR), Dhaka, Bangladesh. Thirty (30) patients with closed fracture distal 3rd extra-articular humeral shaft fractures were treated by open reduction and internal fixation by locking compression plate. Two cases were excluded from the evaluation of final outcome due to their discontinued follow up. Detailed clinical conditions of all patients, technical difficulty with the implant, postoperative hospital stay period were recorded. Patients were followed up at 2nd week, 4th week, then 4 weekly upto 6 months. The patients were evaluated clinically and radiologically for outcomes. The progresses of healing as well as occurrence of complications were recorded. The range of motion of the shoulder and elbow were evaluated according to the criteria by Rommens grading. Functional evaluation was made according to the criteria by Modified Constant and Murley Scoring System. Union was achieved in all the patients after a mean of 15 weeks (range 12-20 weeks). There were no complications like deep infection, nonunion, malunion, implant failure, or nerve injury occurs in any of the patients. Two patients had transient radial nerve palsy. Two patients developed superficial infection. All patients were relieved pain postoperatively. Functional outcome were excellent in 10 patients, good in 15 patients which constituted 89% satisfactory results. The study has shown that the LCP is an effective, dependable solution for the management of distal third diaphyseal fractures of the humerus.

Abstract
BACKGROUND Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery. METHODS This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy. RESULTS Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI. CONCLUSIONS After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

Abstract
In the current literature, the rate of return to sports following high tibial osteotomy is high. Patients are largely able to carry out the type of exercise done before the onset of symptoms and are satisfied with the clinical outcome. In general, however, a differentiated view of the sporting ability should be made, and the different requirements of the sport should be considered. A classification according to functional and biomechanical movement analysis seems to advisable. In addition, the recommendations of the treating physician seem to have a high impact on the postoperative level of the sports activities of the patients. A realistic assessment (by both the patient and the treating physician) that considers the sport, its requirements and the level of performance is necessary.

Abstract
Intestinal fibrosis is a major complication in inflammatory bowel diseases, but the regulatory mechanism that inhibits fibrosis remains unclear. Here we demonstrate that Itch-/-myofibroblasts express increased amounts of profibrotic collagen type I and α-SMA in response to IL-17. Mechanistically, we demonstrate that Itch directly binds to HIC-5 and targets it for K63-linked ubiquitination to inhibit IL-17-driven intestinal fibrosis. Reconstitution of Itch-/- myofibroblasts with wild-type Itch but not the Itch-C830A mutant normalized the expression of profibrotic genes. Similarly, shRNA-mediated inhibition of HIC-5 normalized the expression of profibrotic gene expression. Thus, we have uncovered a novel mechanism by which Itch negatively regulates intestinal fibrosis.

Abstract
BACKGROUND We have previously reported a non-invasive, semi-automated technique to assess motility of the wall of the ascending colon (AC) using Magnetic Resonance Imaging. This study investigated the feasibility of using a tagged MRI technique to visualize and assess the degree of flow within the human ascending colon in healthy subjects and those suffering from constipation. METHODS An open-labeled study of 11 subjects with constipation and 11 subjects without bowel disorders was performed. MRI scans were acquired fasted, then 60 and 120 minutes after ingestion of a 500 mL macrogol preparation. The amount of free fluid in the small and large bowel was assessed using a heavily T2-weighted MRI sequence. The internal movement of the contents of the AC was visualized using a cine tagged MRI sequence and assessed by a novel analysis technique. Comparisons were made between fasting and postprandial scans within individuals, and between the constipation and control groups. KEY RESULTS Macrogol significantly increased the mobile, MR visible water content of the ascending colon at 60 minutes postingestion compared to fasted data (controls P=.001, constipated group P=.0039). The contents of the AC showed increased motion in healthy subjects but not in the constipated group with significant differences between groups at 60 minutes (P<.002) and 120 minutes (P<.003). CONCLUSIONS AND INFERENCES This study successfully demonstrated the use of a novel MRI tagging technique to visualize and assess the motion of ascending colon contents following a 500 mL macrogol challenge. Significant differences were demonstrated between healthy and constipated subjects.

Abstract
BACKGROUND Investigating tumour evolution and acquired chemotherapy resistance requires analysis of sequential tumour material. We describe the feasibility of obtaining research biopsies in women with relapsed ovarian high-grade serous carcinoma (HGSC). METHODS Women with relapsed ovarian HGSC underwent either image-guided biopsy or intra-operative biopsy during secondary debulking, and samples were fixed in methanol-based fixative. Tagged-amplicon sequencing was performed on biopsy DNA. RESULTS We screened 519 patients in order to enrol 220. Two hundred and two patients underwent successful biopsy, 118 of which were image-guided. There were 22 study-related adverse events (AE) in the image-guided biopsies, all grades 1 and 2; pain was the commonest AE. There were pre-specified significant AE in 3/118 biopsies (2.5%). 87% biopsies were fit-for-purpose for genomic analyses. Median DNA yield was 2.87 μg, and was higher in biopsies utilising 14 G or 16 G needles compared to 18 G. TP53 mutations were identified in 94.4% patients. CONCLUSIONS Obtaining tumour biopsies for research in relapsed HGSC is safe and feasible. Adverse events are rare. The large majority of biopsies yield sufficient DNA for genomic analyses-we recommend use of larger gauge needles and methanol fixation for such biopsies, as DNA yields are higher but with no increase in AEs.
