Abstract
UNLABELLED Multiple myeloma (MM) is a hematologic malignancy, characterized by the neoplastic proliferation of plasma cells producing a monoclonal immunoglobulin. Patients presents with signs and symptoms related to the infiltration of plasma cells into the bone or other organs or to kidney damage from excess light chains. Renal involvement with various presentations may be the first manifestation of the disease. MATERIAL All patients of MM presenting with renal dysfunction between July 2019 to June 2021 were included. Diagnosis of MM was made according to the 2014 guidelines of international myeloma working group. OBSERVATION Out of total 144 cases of multiple myeloma renal involvement was present in 43 (29.8%). Mean age of study population was 55.49 years with 72% males. Most common clinical features were fatigue (59%), anorexia (47%) & edema (42%). Anemia was present in 79%, hypercalcemia in 16.2% and hyperuricemia in 20.9% patients. Renal failure was present in 72.1% with a mean eGFR 35.8 ml/min/1.73m2. Serum protein electrophoresis revealed M band in 81.4% and all except one patient had increased light chains in serum. Most common histological lesion were myeloma cast nephropathy (39.5%), primary amyloidosis (30.2%) & monoclonal immunoglobulin deposition disease (14%). Primary amyloidosis group had maximum 24-hour proteinuria and highest eGFR. CONCLUSION The spectrum of renal involvement in multiple myeloma is heterogenous. It mainly affects middle and elderly age group. Typical clinical features might not be seen in all the cases and therefore a high index of suspicion in unexplained renal failure cases might help in early diagnosis and timely management.

Abstract
PURPOSE Calcium sensing receptor (CaSR), on the surface of normal parathyroid cells, is essential for maintaining serum calcium levels. The normal pattern of CaSR immunostaining remains undefined and is presumptively circumferential. Given the physiological variation in serum calcium, we postulated that CaSR expression could not be uniformly circumferential. Also, cytoplasmic expression has not been evaluated either in normal or pathological tissues. We studied normal parathyroid tissues derived from forensic autopsies and those rimming parathyroid adenomas for membranous and cytoplasmic CaSR immunoexpression. Results were compared with primary hyperparathyroidism (PHPT) to look for any pathogenetic implications. MATERIALS AND METHODS We evaluated 34 normal parathyroid tissues from 11 autopsies, 30 normal rims, 45 parathyroid adenoma, 10 hyperplasia, and 7 carcinoma cases. Membranous expression was categorized complete/incomplete and weak/moderate/strong; scored using Her2/Neu and Histo-scores; predominant pattern noted. Cytoplasmic expression was categorized negative/weak/moderate/strong; predominant intensity noted. RESULTS Normal autopsy-derived parathyroid tissues were Her2/Neu 3 + , but incomplete membranous staining predominated in 85%. Their immune-scores were significantly more than the cases (p < < 0.05). The mean histo-score of normal rims was intermediate between the two (p < < 0.05). Cytoplasmic expression was strong in all autopsy-derived tissues, weak/negative in hyperplasia (100%), moderate in 16% adenomas, and 43% carcinomas. CONCLUSIONS Normal autopsy-derived parathyroid tissues showed strong but predominantly incomplete membranous expression. Surface CaSR expression decreased in PHPT and is probably an early event in parathyroid adenoma, seen even in normal rims. Whether there is a defect in CaSR trafficking from the cytoplasm to the cell surface in adenoma and carcinoma needs further evaluation.

Abstract
BACKGROUND The purpose of this study was to review whether routine usage of indocyanine green (ICG) perfusion assessment during complex ileal J-pouch surgery requiring lengthening maneuvers reduces ischemic complications. METHODS Retrospective chart review of patients with ulcerative colitis (UC) or familial adenomatous polyposis (FAP) who underwent ileal pouch-anal anastomosis (IPAA) surgery with lengthening maneuvers and intraoperative ICG assessment between January 2015 and January 2021. All patients underwent a double stapled anastomosis and were temporarily diverted. All patients underwent laparoscopic and trans-anal ICG assessment of their J-pouch and anastomosis. All J-pouches were evaluated 6 weeks after surgery via contrast enema and pouchoscopy. RESULTS One hundred fifty eight patients underwent ileal J-pouch surgery during the study period. Sixteen patients (10%) underwent lengthening maneuvers and intra-operative ICG assessment. Twelve patients underwent surgery for UC and 4 for FAP. Median age was 40.3 years and average body mass index was 24.9 kg/m2. Twelve patients underwent a two-stage procedure and the remaining underwent a three-stage procedure. 93.7% of cases were completed laparoscopically (15/16). All patients underwent scoring of the peritoneum and 43% (7/16) underwent division of the ileocolic or intermediate mesenteric vessels. There was no mortality or pouch ischemia and the leak rate was 12.5%. All patients underwent reversal after an average of 18 ± 7 weeks. CONCLUSION ICG perfusion assessment appears to be of utility in complex IPAA surgery requiring lengthening maneuvers. Its application may be associated with reduced J-pouch ischemia and leak rate in this unique setting.

Abstract
Background The study aims to understand the effect of COVID lockdown on MCH for slum dwellers and coping mechanisms adopted in Indore and Agra, India. Slum women's perspectives on seeking, delaying, avoiding healthcare in COVID-19, barriers and facilitators were explored. Methods In-person qualitative interviews were conducted in slums in Sept-Oct 2020 with mothers who had deliveries; pregnant women needing ante-natal care; mothers with children <2 yrs needing immunization during COVID lockdown. 30 mothers requiring these MCH services during April -June 2020 (lockdown phase) were interviewed. We chose qualitative study over quantitative as a shorter and useful precedent to replicate in similar situations. Results Govt. and most private hospitals refused non-COVID services during lockdown.; Police restricted movement on roads. Being on COVID duty, frontline health functionaries were not doing outreach health sessions. Women missed ante-natal check-up, Iron Folate, Tetanus toxoid; Demand side challenges included fear of COVID infection, lack of money due to livelihood loss; Home deliveries by self, neighbors were resorted to; Maternal, neonatal deaths ensued; Children missed immunization e.g., Measles, DPT. Few peri-urban slum families visited nearby rural health facility for delivery. Some families borrowed money from community saving's groups for delivery in private hospitals. Few families visited low-cost private doctor/nurse for immunization of pregnant mother, children. Conclusions Demand and supply side factors led to pregnant women and children not receiving care during lockdown. Peri-urban slum families should be encouraged to link with nearby rural health facility for MCH services during COVID-19 or similar situations. Govt. partnering with private providers near slums will help access during challenging times. Promoting community savings groups as mandated under National Urban Health Mission can enable slum families borrow with ease when in need. Key messages Government health system should set up emergency (e.g., mobile clinic) MCH services for future epidemic, disaster, should partner with private doctors/nurses near slums. Rural health infrastructure serving nearby peri-urban slums formally recognized by Govt. despite separate jurisdictions is an approach adaptable in LMIC cities.

Abstract
Abstract
Issue
With livelihood loss, uncertain earning, slum families are often food insecure, at risk of undernutrition particularly during COVID-19 in Indian and other LMIC cities. While wheat flour was provided free during lockdown, later at subsidized costs and during non-COVID times, vegetables need to be bought at market price.
Methods
UHRC provided seeds, encouraged families to grow vegetables in slums of Indore, India for five years. In 2019-20 and 20-21, data was gathered through interviews, observations in 20 slums (where >15 families grew vegetables).
Results
Uptake of seeds increased from 900 families in 2019-20 to 1200 in 20-21. With sharing of surplus harvest, 70,000 persons benefited in 2020-21. Families overcame food insecurity by arranging just wheat flour and cooked a vegetable for a meal. Used paint tubs, broken buckets and small spaces were used. Creepers were made to climb on roofs, walls, trees. Green cover increased to > 8 acres in 2021. The practice saves valuable family resources particularly in COVID-19 distress through provision of vegetables for family consumption.
Lessons
Perseverant efforts are key and help build a ‘fairer, healthier world'. Yield per family increased as they grow with incremental confidence. Despite small spaces slum families creatively grew vegetables. Children and youth help overcome constraints and are key actors. Early adopters serve as motivators and champions for subsequent adopters who begin growing vegetables on observing neighbours, friends grow vegetables and share with them. Nurturing plants, seeing vegetables grow fostered positivity, hope, motivation to grow every year, enhanced self-worth, and a positive feeling about their abode. People particularly children and youth learn how eating home-grown vegetables reduces carbon footprint of purchased vegetables transported to urban markets, save cost and overcome food insecurity. They reduce ambient air temperature to cool urban spaces.
Key messages
Despite small spaces, slum families grow, share vegetables, feel accomplished, enable food security, social cooperation, all crucial to well-being of slum populations. Methods used and lessons learnt of perseveringly motivating slum families have the potential of replication/adaptation in cities of India and other LMICs.

Abstract
Abstract
Background
Birth preparedness and complication readiness (BPACR), promotes utilization of skilled maternal and neonatal care. Preparing for childbirth reduces delays in seeking care. Brick-kiln workers constitute a vulnerable social group who contribute to city infrastructure by laboring at low wages. 37% of the sample were Scheduled Castes, 49% Scheduled Tribes.
Methods
139 mothers of children < 2 years, residing temporarily in brick kilns of Indore were asked about preparedness for birth of youngest child. Birth preparedness was assessed by enquiring about saving money, arranging transport, identifying health facility for delivery, identified family member to accompany for labor/emergency.
Findings
10% did >3 BPACR practices implying good level of preparedness; 50% did 1-2 BPACR practices; 40% did no birth preparedness. Access to maternity benefit scheme was twice as likely to result in reasonable birth preparedness as compared to no access. Those with primary to class XII were twice as likely to practice birth preparedness as compared to those with no formal education. >3 ANC was associated with 8 percentage points greater practice of reasonable BPACR as compared to < 2 or no ANC. Mothers with knowledge of one danger sign each of pregnancy and delivery were 3 times more likely to practice BPACR than those without this knowledge. FGDs revealed challenges in access to bank account, obtaining required documents to apply for and access state maternity benefit. Lack of family support led to low BPCAR and low institutional delivery.
Conclusions
Brick-kiln women face risk of low utilization of government healthcare services. The health systems should conduct outreach antenatal care sessions in brick-kilns on knowledge of key danger signs and BPACR during health education and ANC counselling can help promote BPACR and hospital delivery. Information on requisite steps to apply for maternity benefit schemes should be shared among brick-kiln workers.
Key messages
It is crucial to promote BPACR among urban vulnerable sections, through NUHM’s outreach sessions by ANMs/ASHAs in brick-kiln, construction workers and similar groups. Access to maternity benefit cash transfer scheme should be enhanced particularly among excluded temporary urban groups such as brick-kiln workers as it is a motivation to avail hospital care.

Abstract
Coating modification such as drug-eluting coating is one of the most important approaches for the functionalization of biomedical devices. However, the throughputs are limited in conventional coating methods and the concept of miniaturization is rarely fulfilled. A droplet microarray (DMA), as a unique high-throughput platform, can avoid cross-contamination and reduce the consumption of materials which is inherently suitable for coating research yet is difficult to apply with coating materials via traditional methods. Here, we bring up a facile method based on ultrasonic spray deposition to integrate coating materials into a DMA. Several common polymer materials were selected to fabricate a DMA, and the obtained DMA showed the ability to anchor water droplets and form specific patterns. Coating arrays with a typical sandwich structure were also prepared for the high-throughput screening of drug-eluting coatings to demonstrate the potential of the platform in coating research. This developed method is efficient and compatible and enriches the choices of materials that can be applied in DMAs.

Abstract
Abstract
Aim
To evaluate the outcome of distal femoral replacements versus internal fixation for elderly patients with distal femoral periprosthetic fracture in a single institution.
Method
A five-year retrospective observational study was conducted of a consecutive series of patients with distal femoral periprosthetic fracture who underwent either distal femoral replacement (DFR) or internal fixation (IF) in a tertiary referral centre. Clinical information analysed included patient demographics, co-morbidities, interval between primary total knee arthroplasty (TKA) to distal femoral periprosthetic fracture, type of fracture, operative technique, preoperative ASA grade, post-operative complications, intensive therapy unit (ITU) stay, length of hospital stay (LOS), re-fixation and mortality.
Results
Study included 27 patients of which fourteen patients underwent a DFR while 13 underwent an IF. 89% of the patients were females. Mean age of the patients at the time of fracture was 85 versus 80 (DFR vs IF). The mean interval from the primary TKA to the fracture were 80 months (range 0-181). There were no intraoperative complications in either group. Three patients required ITU stay from the DFR group while one patient from the IF group required re-fixation. Median LOS was 56 days (range 9-144) after DFR and 55 days (range 4-83) after IF. There was one 30-day mortality in the DFR group. One-year mortality for the DFR group was 7% vs 15% for the IF group.
Conclusions
In our study, DFR and IF were observed to have similar LOS with a higher mortality in the IF group at one year. There was one re-fixation in the IF group.

Abstract
Abstract
Aim
In knee replacements, restoration of mechanical alignment is essential. Patients with extra-articular deformities (EAD) pose challenges in planning knee replacements. We present a method, based on our experience and review of literature on planning knee replacement surgery, in the presence of extra-articular coronal plane deformity of the tibia.
Method
Retrospective analysis was made of six patients with EAD of the tibia who underwent knee replacement at our centre. Mechanical axis of the tibia is considered and positioning of the tibia component is planned perpendicular to the mechanical axis of the tibia. The integrity of the collaterals determines the need for correction. Tibial resection >15mm from medial or lateral aspect of the tibia is an indication for corrective osteotomy prior to replacement surgery. The hip knee ankle angle (HKA) was noted. Pre-operative, post-operative clinical score, degree of constraints and post-operative complications were recorded. A post-operative long leg alignment radiograph was obtained.
Result
All patients had total knee replacement without correction of deformity. Adequate alignment of the limb and restoration of mechanical axis was achieved in all six patients without the need for correction of tibial deformity. All patients had improvement in their HKA angle and Oxford knee score. No re-operations were required, and no complications recorded.
Conclusions
Our study will help provide guidance on operative planning and decisions making for patients with extra-articular coronal plane tibial deformities.

Abstract
Introduction: Fractures around the hip in the geriatric population not only lead to functional but also psychological impairment. Psychiatric disturbances can be associated with poor participation in rehabilitation, increased risk of falling again, and higher rates of mortality. The present study was undertaken to assess the association between the psychological status and functional outcome of surgically managed elderly Indian patients who had sustained fractures around the hip. Material and Methods: The present study was a hospital based prospective, single centre study. One hundred and two geriatric patients who had sustained hip fracture and had been managed surgically, having no cognitive dysfunction, living independently, having unhindered walking capability before the fracture, were included in the study. They were called for follow-up at 3rd, 6th, and 12th month after the hip surgery. Psychological assessment was done by the Hospital Anxiety and Depression Scale (HADS) and functional outcome by using the Harris hip score (HHS). Results: Our study did not show association between psychological status and functional outcome except in one sub-group. Significant correlation was observed between the psychological status and functional outcome in most of the patients in the extra-capsular group. We have identified improvement in the depression, anxiety and functional scores during the follow-up. Conclusion: We conclude that psychiatric disturbances in a geriatric patient after undergoing a surgery for hip fracture may lead to poor recovery. We recommend that all such geriatric patients should undergo a psychological assessment and proper therapy should be instituted to achieve good functional recovery.

Abstract
AbstractGreen tea or its concentrated extract is coveted for its health promoting catechin-like polyphenols, especially epigallocatechin-3-gallate (EGCG). However, its amicable efficacy is now being doubted considering the recent occurrence of several cases of hepato- and nephrotoxicity, after the ingestion of EGCG-fortified (≥85–90%) nutritional supplements. Therefore, the current study was carried out to ascertain the effect of green tea leaves extract (GTE), having low EGCG content (73.8%), on liver and kidney functions of male Wistar rats using various in vivo experiments and in vitro radical scavenging activity. In terms of acute toxicity, GTE was observed to be safe when delivered at a dosage of 2000 mg kg−1 body weight (BW). Oral delivery of GTE for 28 days at a concentration of 200 mg kg−1 BW/day did not trigger sub-acute toxicity to the liver and kidneys, as per serum biochemical analyses and histopathological examination. In contrast, GTE counteracted the effects of carbon tetrachloride (a potent hepato-degenerative compound) on the liver. Furthermore, increase in high-density lipoprotein―cholesterol with concomitant lowering of serum triglycerides and low-density lipoprotein―cholesterol were noticed in GTE-treated rats. These findings suggest that low EGCG containing GTE, with appreciable antioxidant activity (IC50 = 53.18–71.28 μg mL−1), can serve as a hepatoprotective, hypolipidemic, and hypocholesterolemic ingredient.

Abstract
BACKGROUND The technical difficulty and steep learning curve of transanal total mesorectal excision (taTME) has limited widespread adoption. The single-port (SP) daVinci robot is designed to facilitate single-incision and natural-orifice transluminal endoscopic surgery (NOTES). This paper describes the first clinical experience of single-port robotic taTME (SP rTaTME). METHODS This was a prospective study on consecutive patients with rectal cancer who underwent SP rTaTME proctosigmoidectomy with handsewn coloanal anastomosis in December 2018 and January 2019. The primary outcome was technical feasibility of the procedure. The secondary outcomes include blood loss, intraoperative complications, length of hospital stay, quality of the TME specimen, short- and long-term morbidity and mortality, as well as short-term oncologic follow -up. RESULTS There were two patients, a 48-year-old male and a 38-year-old female. Both operations were completed successfully without complications or conversion. Estimated blood loss was 200 mL and 130 mL. In both cases the TME was completed transanally using the SP robot. In the first patient, the abdominal portion was completed through an abdominal single-incision; in the second patient the operation was entirely performed transanally as a pure NOTES procedure. In both cases, the final pathology report showed a complete TME with negative margins. Patients were discharged on postoperative day 3 and 4,respectively. There was no long-term morbidity or mortality. CONCLUSIONS SP rTaTME is feasible and can be safely performed. It provides excellent optics and dexterity to work in a limited space. Future studies are required to further define the safety profile and the ultimate utility of the SP robot for taTME.

Abstract
Microarrays have become extremely powerful experimental tools for high-throughput screening of cell behaviors in multivariate microenvironments. Herein, a microarray-based high-throughput platform with biochemistry gradients was developed using poly(limonene carbonate) (PLimC) as a substrate through thiol-ene click chemistry. ATR-IR, XPS, Raman spectrum, and water contact angle results demonstrated that the sulfhydryl molecules, including PEG (polyethylene glycol) and RGD (arginine-glycine-aspartic acid) peptide, could be grafted onto PLimC substrates, while the grafting density could be well controlled by regulating the intensity of UV irradiation. Then, microarrays with a gradient of RGD grafting density were fabricated by using UV irradiation patterned by a photomask and a gradient light filter. Adhesion experiments of smooth muscle cells and 3T3-L1 mouse embryonic fibroblast cells proved that the cell behaviors were highly determined by the RGD density. This platform puts forward a facile, high-throughput method to study the effect of biochemical signal density on cell behaviors.
