Soil salinity is a severe threat in arid and semiarid agro‐ecosystem of India, and it is directly influenced by soil physical properties. Therefore, understanding the dynamic nature of salinity is the key to implementing suitable management options for re‐builing the fertility of saline soils. In this context, we conducted field experiments in saline soil, comprising five treatments (1‐5 following) and a control (C). These are: C) no amendments and chemical fertilizer; T1) recommended dose nitrogen, phosphorus, and potassium (N‐P‐K) fertilizers @60:30:30 kg ha−1; T2) 100% recommended dose of chemical fertilizers (RDF).; T3) rice straw compost (RSC) @14 Mg ha−1; T4) gypsum enriched compost (GEC) @14 Mg ha−1; and T5) municipal solid waste compost @16 Mg ha−1 (MSWC) applied for three consecutive years (2012 to 2015). Our results revealed that compost and chemical fertilizer had significant effect on soil organic carbon, soil aggregate stability indices, soil water retention, transmission characteristics, and pore size distribution. This improvement in soil physical properties imparted into better soil physical environment and significant reduction in soil salinity (75%) was apparent with application of MSWC. Multivariate analysis indicated that mean weight diameter (MWD) and retension pores (RP) were the two main soil physical properties that help to reduce soil salinity. Our results revealed that, MWD increased by 49.1% in MSWC and 37.7% in GEC over control (C) (0.53 mm). Improvement in soil environment under composted soil produced significantly higher grain yield of mustard (2.22 Mg ha−1) and pearl millet (2.29 Mg ha−1) with MSWC as compared to control (C). Organic amendments significantly improved the soil physical environment. [ABSTRACT FROM AUTHOR]

Private firms in monopsony undertake disruptive innovation like contract farming (CF), where the firm invests in the food supply chain, provides credit, assumes the risk, and implements management strategies. This study investigates the impact of monopsonist involvement in CF and its impact on food security indicators among smallholders. Findings reveal that the monopsonist CF structure for ginger processing in Nepal increases the market price by about 18%, yields by 10%, and profits by 66%. However, the impact varies with farm size. Small farms (≤0.51 hectares (ha)) engaged in CF have higher yields (18%), earn higher profits (81%), and receive higher market prices (12%) than small noncontract ginger producers. Contrary to popular belief, disruptive innovation in value chains by monopsonists could lead to higher yields, the market price received, and profitability for both small and large farmers.

Using a survey of 1,500 farmers, we identify farmer-level constraints to adoption of modern cultivars in Rajasthan, India, and decompose the overall elasticity into the elasticities of adoption probability and use intensity. We find that access to credit and intensity of extension services received drive adoption of modern cultivars, but both factors are more important for determining adoption probability than for determining use intensity. Moreover, the study assesses the roles that key traits of individual cultivars play in their adoption. Varietal traits significant for the adoption of modern cultivars vary by crop and geography. However, the main driver for continuing old cultivars across crops is taste attributes. [ABSTRACT FROM AUTHOR]

Wood plastic composites (WPC) were made from polypropylene (PP), impact copolymer (ICP) and wood flour (WF) by varying the WF content from 10 to 40% with PP grafted maleic anhydride as a coupling agent. The effect of varying WF content was studied on rheological, thermal, mechanical properties and dynamic mechanical properties. Experimental small amplitude oscillatory shear (SAOS) data was compared with the Einstein–Batchelor and empirical Krieger–Dougherty relations. Significant dependence of mechanical and rheological properties on WF content was observed. Young's modulus, flexural modulus and dynamic shear viscosity increased with WF content. Results of dynamic mechanical analysis (DMA) showed increase in storage modulus with WF content. Three millimeter thick compression molded composites sheets were thermoformed using axisymmetric molds with two draw depths. Sag observed visually during thermoforming decreased with increasing WF content. Components made from the composites showed close to uniform thickness distribution as compared to those from ICP.

Hospital-acquired infections, including surgical site infections (SSIs), pose a concerning challenge because of the growing resistance to multiple drugs, largely influenced by extensive prophylactic antimicrobial therapy. Although SSIs are well documented in advanced hospitals in developed nations, their prevalence and bacterial profiles are inadequately reported in low- and middle-income nations such as Nepal. This retrospective cohort study explored the prevalence of orthopaedic SSIs in relation to bacterial etiology and antimicrobial resistance. We examined the surgical and bacteriological records of patients suffering SSIs (clean or clean-contaminated wounds) within a month of their surgical procedures between January 2020 and June 2022 at the National Trauma Center, Kathmandu, Nepal. The prevalence of orthopaedic SSIs among hospital-visiting patients was 31.2% (448/1,438; 95% CI: 28.8-33.5). There were 341 (76.1%) males and 361 (80.6%) adults with SSIs. Knee/joint infections (n = 141, 31.5%) were predominant. An SSI typically occurs 7 days after surgery. Enterobacterales were dominated by Escherichia coli (n = 54, 40.9%), whereas nonfermenters gram-positive cocci (GPC) were dominated by Pseudomonas aeruginosa (n = 69, 81.2%) and Staphylococcus aureus (n = 216, 93.5%), respectively. Enterobacterales, nonfermenters, and GPC exhibited penicillin resistance at 74.5%, 29.8%, and 65.1%, respectively, whereas cephalosporin resistance was exhibited at 48.3%, 57.1%, and 49.6%; fluoroquinolone resistance at 25.9%, 40.5%, and 25.7%; and aminoglycoside resistance at 21.5%, 43.2%, and 17.3%. One-third of orthopaedic surgeries resulted in SSIs, mainly caused by S. aureus. Fluoroquinolones and aminoglycosides were moderately effective in treating bacterial SSIs, whereas penicillins and cephalosporins were the least effective. Nonfermenters exhibited higher antimicrobial resistance compared with Enterobacterales and GPC.

Introduction: In orthopaedic practice, injuries to the anterior cruciate ligaments occur almost on an epidemic scale, yet it continues to be of interest in orthopaedic surgery whether semitendinosus or gracilis hamstring autografts can be used for better anterior cruciate ligament reconstruction. This study aimed to determine the prevalence of anterior cruciate ligament reconstruction using semitendinosus tendon autografts among paramilitary patients undergoing arthroscopic surgery in a tertiary care centre., Methods: This descriptive cross-sectional study was conducted among paramilitary individuals who had knee injuries and were admitted between 6 february 2020 and 26 January 2022 for arthroscopic surgery after obtaining ethical approval from the Institutional Review Committee. Demographic details and the mode of injury were obtained from the patients. The treating orthopaedic surgeons evaluated the pre- and post-analysis Lysholm Knee Score and Lysholm Knee Scale based on the patient's response. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval., Results: Among 166 patients, anterior cruciate ligament reconstruction using a semitendinosus tendon autograft was done in 58 (34.94%) (27.69-42.19, 95% Confidence Interval). Most of the patients in the pre-analysis had mild/periodic limp issues 52 (89.66%), followed by instability during athletics or other severe exertion 43 (74.14%)., Conclusions: The prevalence of anterior cruciate ligament injuries in our study is higher than other studies done in similar settings., Keywords: anterior cruciate ligament; grafts; semitendinosus tendon.

Introduction: Orthopedic fractures caused by chronic metabolic bone disease, overuse, or road traffic accidents are among the most significant burdens on society. Furthermore, a growing number of people undergoing arthroplasty and an increase in life expectancy seem to contribute to an increase in orthopaedic fractures.

The objective of this study was to find out the prevalence of orthopaedic fractures among patients attending a tertiary care centre., Methods: A descriptive cross-sectional study among patients attending a tertiary care centre was conducted between 19 May and 18 November 2023 during which date from 1 January to 30 December 2021 were collected from the hospital records. Ethical approval was obtained from the Institutional Review Committee. A convenience sampling method was used. Point estimate was calculated at a 95% Confidence Interval., Results: Among 7609 people, 2518 (33.09%) (12.97-10.55, 95% Confidence Interval) had orthopaedic fractures. A total of 1925 (76.45%) were males. There were 339 (95.49%) fractures associated with two-wheelers and 307 (86.48%) with four-wheelers. There were 1387 (55.08%) soft tissue injuries, 198 (7.86%) skull injuries, and 116 (4.61%) facial injuries. Additionally, there were 73 (2.90%) fractures of the femur, 71 (2.82%) fractures of the phalanx, and 70 (2.78%) fractures of the clavicle., Conclusions: The prevalence of orthopaedic fractures was found to be higher than in other studies done in similar settings., Keywords: bone fracture; orthopedics; prevalence; tertiary care centre.

Introduction: Driving under the influence is one of the most significant risk factors for road traffic accidents, leading to severe and multiple orthopaedic injuries. The aim of this study was to find out the prevalence of driving under the influence of alcohol among road traffic accident patients presenting to a tertiary care centre., Methods: A descriptive cross-sectional study was conducted on patients involved in road traffic accidents presenting to a tertiary care centre. Data from 10 January 2020 to 9 December 2021 were collected between 22 July 2023 to 22 August 2023 from the hospital records after receiving ethical approval from the Institutional Review Committee. Patients who had road traffic accidents and were diagnosed with fractures were included in the study. Patients with incomplete hospital records were excluded from the study. Convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval., Results: Among 2,519 patients, 307 (12.19%) (10.91-13.47, 95% Confidence Interval) were driving under the influence of alcohol when involved in a road traffic accident. Out of 307 patients, 305 (99.35%) accidents involved two-wheelers. A total of 118 (38.44%) patients suffered soft tissue injuries, while 47 (15.31%) sustained head injuries, and 28 (9.12%) sustained facial injuries., Conclusions: The prevalence of driving under the influence of alcohol among road traffic accident patients presenting to a tertiary care centre was similar to other studies done in similar settings., Keywords: accidents; alcohol consumption; bone; Nepal; trauma.

Introduction: Vitamin D deficiency is a global health issue affecting billions of people. Its deficiency results in abnormal homeostasis of calcium and phosphorous levels in an individual and results in reduced bone mineral density, which further makes them more prone to develop osteogenic disorders, such as fractures. The aim of this study is to find out the prevalence of vitamin D deficiency among patients visiting the outpatient departments in a tertiary care centre., Methods: This was a descriptive cross-sectional study done among 582 patients visiting outpatient departments in a tertiary care centre between January 1, 2019 and July 31, 2020. The study was approved by the Institutional Review Committee (Reference number: 076/077/17) of a tertiary care centre. A convenience sampling method was used. Patients' demographic detail and serum vitamin D level were determined. Data were collected retrospectively from hospital records and analysis was performed using the Statistical Package for the Social Sciences software version 17.0. Point estimate at 95% Confidence Interval was calculated along with frequency, the proportion for binary data, and mean with standard deviation for continuous data., Results: Among 582 patients enrolled in this study, 328 (56.35%) (52.32-60.38 at 95% Confidence Interval) patients were vitamin D deficient. Vitamin D deficiency was found in 238 (72.56%) females and 257 (78.35%) aged 16 to 59 years. Finally, there were 102 (31.09%) cases of vitamin D deficiency over the winter season., Conclusions: The prevalence of serum vitamin D deficiency in the current study was lower when compared to similar studies done in similar settings and similar to the prevalence from international literature., Keywords: deficient; prevalence; vitamin D.
