Ossification of sacrospinous ligament induces a great risk for maintaining the stability of the pelvis. The sacrospinous ligament, along with the sacrotuberous ligament, plays a distinct role in the sacroiliac joint and pubic symphysis stability. The ossification may cause compression of neurovascular structure traversing through the greater and lesser sciatic foramen. Here we report a case of unilateral heterogenous ossification of the left sacrospinous ligament causing sciatic nerve compression and sciatic pain. A 22-year-old Bangladeshi woman, mother of one child, presented with complaints of pain in the lower back, left buttock and back of the upper thigh. Clinical examination and investigations revealed a diagnosis of the partially ossified sacrospinous ligament with sciatic nerve compression. Total excision of heterotrophic calcification and partial excision of left sacrospinous ligament through posterior approach by a left paramedian incision over the lower back was performed under general anaesthesia. On outpatient follow-up visits at 2 weeks and 6 weeks post-surgery, complete disappearance of pain was observed, and the patient was able to return to regular productive life activity. In this report, we presented a rare case of ossified sacrospinous ligament causing sciatic nerve compression with unknown etiology. The surgical approach performed, total excision of heterotrophic calcification and partial excision of left sacrospinous ligament through the posterior approach helped to preserve the pelvic stability with a good clinical outcome.

Although metal-organic frameworks (MOFs) and metalo hydrogen-bonded organic frameworks (MHOFs) are designed as promising solid-state proton conductors by incorporating various protonic species intrinsically or extrinsically, design and development of such materials by employing the concept of proton conduction through coordinated polar protic solvent is largely unexplored. Herein, we have constructed two proton-conducting materials having different solvent coordinated metal cationic species: In-H2O-MOF, ({[In(H2O)6][In3(Pzdc)6]·15H2O}n; H2Pzdc: pyrazine-2,3-dicarboxylic acid) with coordinated water molecules from hexaaquaindium cationic species, and MHOF-4, ([{Co(NH3)6}2(2,6-NDS)2(H2O)2]n; 2,6-H2NDS: 2,6-naphthalenedisulfonic acid) with coordinated ammonia from hexaammoniacobalt cationic species. Interestingly, higher proton conductivity was achieved for In-H2O-MOF (1.5 × 10-5 S cm-1) than MHOF-4 (6.3 × 10-6 S cm-1) under the extreme conditions (80 ºC and 95% RH), which could be attributed to enhanced acidity of coordinated water molecules having much lower pKa value than that of coordinated ammonia. Greater charge polarization on hydrogen atoms of In3+-coordinated water molecules than that of Co2+-coordinated ammonia led to the high conductivity of In-H2O-MOF, as evident by quantum chemical studies. Such a comparative study on metal-coordinated protic polar solvents in achieving proton conduction in crystalline solids is yet to be made., (© 2024 Wiley‐VCH GmbH.)

Despite possessing numerous catalytic advantages of MOFs, developing 2D frameworks having excellent chemical stability along with new catalytic properties, remains a grand challenge. Herein, by employing a mixed ligand synthetic approach, we have constructed a 2D Ni-MOF, IITKGP-52, which exhibits excellent framework robustness in open air, water, as well as over a wide range of pH solutions (2-12). Benefitting from its robustness and abundant Lewis acidic open metal sites, IITKGP-52 is explored in catalyzing the heterogeneous three-component condensation reaction for the tandem synthesis of bioactive 2-amino-3-cyano-4H-pyran derivatives with low catalytic loading, greater compatibility for a wide range of substrates, excellent recyclability and superior catalytic efficiency than the previously employed homo and heterogeneous systems. IITKGP-52 inaugurates the employment of MOF-based catalysts for one-pot synthesis of therapeutic and bioactive 2-amino-3-cyano-4H-pyran derivatives., (© 2024 Wiley‐VCH GmbH.)

Although it is well-known that the Lewis acidity of Metal-Organic Frameworks (MOFs) can effectively enhance their catalytic activity in organic transformations, access to these Lewis-acidic sites remains a key hurdle to widespread applications of Lewis-acidic catalysis by MOFs. Easy accessibility of strong Lewis acidic sites onto 2D MOFs by using proper activation methods can be a cornerstone in attaining desired catalytic performance. Herein, we report a new 2D chemically stable MOF, IITKGP-60, which displayed excellent framework robustness over a wide pH range (2-12). Benefiting from the abundant open metal sites (OMSs) and framework robustness, the catalytic activity of the developed material was explored in one-pot three-component Strecker reaction and Knoevenagel condensation reaction. Moreover, the developed catalyst is superior in catalyzing the reactions involving sterically hindered substrate (1-naphthaldehyde) with high turnover number. A comparative catalytic study was conducted using different activation methods (chloroform and methanol exchanged activated samples), highlighting the significant effect of activation methods on its catalytic performances. The sustainable synthetic pathway under solvent-free conditions for a broad scope of substrates using low catalyst loading and excellent recyclability made the developed pH-stable framework a promising heterogeneous catalyst., (© 2024 Wiley-VCH GmbH.)

Five- and six-membered heterocycles containing nitrogen or oxygen have been considered as privileged scaffolds in organic chemistry and the chemical industry because of their usage in high-value commodities. Herein, we report a two-dimensional (2D) Cu(II)-based MOF catalyst, IITKGP-40, via the strategic employment of ample Lewis acid-base bifunctional sites (open metal nodes and free pyrazine moieties) along the pore wall. IITKGP-40 could convert toxic CO 2 to cyclic carbonates in an atom-economical manner under solvent-free conditions and aromatic aldehyde to bioactive 1,4-DHPs via Hantzsch condensation. Exceptional catalytic performance (99%) and turnover number under mild reaction conditions for CO 2 fixation using sterically hindered styrene oxide, and good-to-excellent yields for a wide range of aromatic aldehydes toward 1,4-dihydropyridines (1,4-DHPs) make IITKGP-40 promising as a multipurpose heterogeneous catalyst. Moreover, to demonstrate the practical utility of the catalyst, two biologically important drug molecules, diludine and nitrendipine analogue, have also been synthesized. IITKGP-40 is recyclable for at least three consecutive runs without significant loss of activity, making it promising for real-time applications.

Development of a simple, cost-efficient, and portable UO 2 2+ sensory probe with high selectivity and sensitivity is highly desirable in the context of monitoring radioactive contaminants. Herein, we report a luminescent Co-based metal-organic framework (MOF), {[Me 2 NH 2 ] 0.5 [Co(DATRz) 0.5 (NH 2 BDC)]· x G} n ( 1 ), equipped with abundant amino functionalities for the selective detection of uranyl cations. The ionic structure consists of two types of channels decorated with plentiful Lewis basic amino moieties, which trigger a stronger acid-base interaction with the diffused cationic units and thus can selectively quench the fluorescence intensity in the presence of other interfering ions. Furthermore, the limit of detection for selective UO 2 2+ sensing was achieved to be as low as 0.13 μM (30.94 ppb) with rapid responsiveness and multiple recyclabilities, demonstrating its excellent efficacy. Density functional theory (DFT) calculations further unraveled the preferred binding sites of the UO 2 2+ ions in the tubular channel of the MOF structure. Orbital hybridization between NH 2 BDC/DATRz and UO 2 2+ together with its significantly large electron-accepting ability is identified as responsible for the luminescence quenching. More importantly, the prepared 1 @PVDF {poly(vinylidene difluoride)} mixed-matrix membrane (MMM) displayed good fluorescence activity comparable to 1 , which is of great significance for their practical employment as MOF-based luminosensors in real-world sensing application.

Metal-organic frameworks (MOFs) have attracted immense attention as efficient heterogeneous catalysts over other solid catalysts, however, their chemical environment instability often limits their catalytic potential. Herein, utilizing a flexible unexplored tetra-acid ligand and employing the mixed ligand approach, a 3D interpenetrated robust framework is strategically developed, IITKGP-51 (IITKGP stands for Indian Institute of Technology Kharagpur), which retained its crystallinity over a wide range of pH solution (4-12). Having ample open metal sites (OMSs), IITKGP-51 is explored as a heterogeneous catalyst in one-pot Hantzsch condensation reaction, with low catalyst loading for a broad range of substrates. The synthesis of drug molecules remains one of the most significant and emergent areas of organic and medicinal chemistry. Considering such practical utility, biologically important Nemadipine B and Nifedipine drug molecules (calcium channel protein inhibitor) are synthesized for the first time by using this catalyst and fully characterized via SC-XRD and other spectroscopic methods. This report inaugurates the usage of a MOF material as a catalyst for the synthesis of drug molecules., (© 2024 Wiley‐VCH GmbH.)

An efficient design of crystalline solid-state proton conductors (SSPCs) is crucial for the progress of clean energy applications. Developing such materials to make them work at room temperature with a conductivity of ≥10 -1 S cm -1 is of significant interest in terms of technical and commercial aspects. Utilizing the recently highlighted "coordinated-water-driven proton conduction" approach, herein, we have rationally synthesized two highly stable and scalable 1D Co(II) coordination polymers (CPs) as SSPCs, PCM-2 {[Co(bpy)(H 2 O) 2 (NO 3 ) 2 ]·H 2 O} n and PCM-3 {[Co 2 (bpy) 2 (SO 4 ) 2 (H 2 O) 6 ].4H 2 O} n , with distinct alignments in coordinated water and coordinated oxo-anions (nitrate and sulfate, respectively). The acidity of the metal-bound water molecules in PCM-2 is further enhanced through cooperative long-range continuous H bonds with coordinated Brønsted basic nitrates (proton acceptors), leading to ultrahigh superprotonic conductivities even at 25 °C (1.03 × 10 -1 S cm -1 under 95% RH), and reached a maximum of 2.99 × 10 -1 S cm -1 at 85 °C (95% RH). The conductivity at 25 °C is even higher than that of commercial Nafion 117 (6.74 × 10 -2 S cm -1 at 100% RH). The absence of such an H-bonding interaction in PCM-3 (closed loops) resulted in a lesser conductivity of 5.87 × 10 -5 S cm -1 (95% RH, 85 °C). PCM-2 represents the first example of SSPC exhibiting conductivity in the order 10 -1 S cm -1 at ambient temperature (25 °C) with excellent recyclability.

For the purpose of fixing tibia fractures, composite bone plates are suggested. Metal plates cause stress shielding, lessen the compression force at the fracture site, and have an impact on the healing process because they are significantly more rigid than bone. To prevent excessive shear strain and consequent instability at the fracture site, it is imperative to reduce stiffness in the axial direction without lowering stiffness in the transverse direction. Only a carefully crafted fiber reinforced composite with anisotropic properties will suffice to accomplish this. The purpose of the current study is to examine the impact of axial and shear movements at the fracture site on the fixing of metal and composite bone plates. After modeling the tibia with a 1 mm fracture gap, titanium plates, carbon/epoxy, carbon/PEEK, and carbon/UHMWPE composite bone plates were used to fix it. There are 6 holes on each of the 103 mm long plates. To determine the stresses and axial movement in the fracture site, anatomical 3D Finite Element (FE) models of the tibia with composite bone plates are built. The simulations that were run for various composite plate layouts and types give suggestions for selecting the best composite bone plate. Although the matrix material causes some variations in behaviors, most of the plates perform as well as or even better than metal plates. Thus, the appropriate composite combinations are recommended for a given fracture structure., (© 2024 IOP Publishing Ltd.)

Plant extracts have been used to treat microbiological diseases for centuries. This study examined plant triterpenoids tormentic acid (TA) and 23-hydroxycorosolic acid (HCA) for their antibiofilm effects on Staphylococcus aureus strains (MTCC-96 and MTCC-7405). Biofilms are bacterial colonies bound by a matrix of polysaccharides, proteins, and DNA, primarily impacting healthcare. As a result, ongoing research is being conducted worldwide to control and prevent biofilm formation. Our research showed that TA and HCA inhibit S. aureus planktonic growth by depolarizing the bacterial membrane. In addition, zone of inhibition studies confirmed their effectiveness, and crystal violet staining and biofilm protein quantification confirmed their ability to prevent biofilm formation. TA and HCA exhibited substantial reductions in biofilm formation for S. aureus (MTCC-96) by 54.85% and 48.6% and for S. aureus (MTCC-7405) by 47.07% and 56.01%, respectively. Exopolysaccharide levels in S. aureus biofilm reduced significantly by TA (25 μg/mL) and HCA (20 μg/mL). Microscopy, bacterial motility, and protease quantification studies revealed their ability to reduce motility and pathogenicity. Furthermore, TA and HCA treatment reduced the mRNA expression of S. aureus virulence genes. In silico analysis depicted a high binding affinity of triterpenoids for biofilm and quorum-sensing associated proteins in S. aureus, with TA having the strongest affinity for TarO (- 7.8 kcal/mol) and HCA for AgrA (- 7.6 kcal/mol). TA and HCA treatment reduced bacterial load in S. aureus-infected peritoneal macrophages and RAW264.7 cells. Our research indicates that TA and HCA can effectively combat S. aureus by inhibiting its growth and suppressing biofilm formation., (© 2023.

The sensing and monitoring of toxic oxo-anion contaminants in water are of significant importance to biological and environmental systems. A rare hydro-stable SIFSIX metal-organic framework, SiF 6 @MOF-1, {[Cu(L) 2 (H 2 O) 2 ]·(SiF 6 )(H 2 O)} n , with exchangeable SiF 6 2- anion in its pore is strategically designed and synthesized, exhibiting selective detection of toxic Cr 2 O 7 2- oxo-anion in an aqueous medium having high sensitivity, selectivity, and recyclability through fluorescence quenching phenomena. More importantly, the recognition and ion exchange mechanism is unveiled through the rarely explored single-crystal-to-single crystal (SC-SC) fashion with well-resolved structures. A thorough SC-SC study with interfering anions (Cl - , F - , I - , NO 3 - , HCO 3 - , SO 4 2- , SCN - , IO 3 - ) revealed no such transformations to take place, as per line with quenching studies. Density functional theory calculations revealed that despite a lesser binding affinity, Cr 2 O 7 2- shows strong orbital mixing and large driving forces for electron transfer than SiF 6 2- , and thus enlightens the fluorescence quenching mechanism. This work inaugurates the usage of a SIFSIX MOF toward sensing application domain under aqueous medium where hydrolytic stability is a prime concern for their plausible implementation as sensor materials., (© 2023 Wiley-VCH GmbH.)

Nowadays, coordination polymers (CPs) are promising candidates as sensory materials for their high sensitivity, improved selectivity, fast responsive nature, as well as good recyclability. However, poor chemical stability often makes their practical usage limited. Herein, employing a mixed ligand approach, we constructed a chemically robust CP, {[Zn 2 L 2 (DPA) 2 ]·3H 2 O} n ( IITKGP-70 , IITKGP stands for the Indian Institute of Technology Kharagpur), which exhibited excellent framework robustness not only in water but also over a broad range of pH solutions (pH = 3-11). The developed framework displayed high selectivity and sensitivity for the detection of trivalent Al 3+ ions and toxic hexavalent Cr(VI)-oxo anions in an aqueous medium . The developed framework exhibited an aqueous medium Al 3+ turn-on phenomenon with a limit of detection (LOD) value of 1.29 μM, whereas a turn-off effect was observed for toxic oxo-anions (Cr 2 O 7 2- and CrO 4 2- ) having LOD values of 0.27 and 0.71 μM, respectively. Both turn-on and turn-off mechanisms are speculated via spectroscopic methods coupled with several ex situ studies. Such a multiresponsive nature (both turn-on and turn-off ) for aqueous medium detection of targeted cations and anions simultaneously in a single platform coupled with high robustness, ease of scalability, recyclability, and fast-responsive nature makes IITKGP-70 highly fascinating as a sensory material for real-world applications.

Metal-organic frameworks (MOFs) have been recognized as one of the most promising porous materials and offer great opportunities for the rational design of new catalytic solids having great structural diversity and functional tunability. Despite numerous inherent merits, their chemical environment instability limits their practical usage and demands further exploration. Herein, by employing the mixed-ligand approach, we have designed and developed a robust 3D Co-MOF, [Co 2 (μ 2 -O)(TDC) 2 (L)(H 2 O) 2 ]·2DMF (H 2 TDC = 2,5-thiophenedicarboxylic acid, L = 3,3'-azobispyridine), IITKGP-50 (IITKGP stands for the Indian Institute of Technology Kharagpur), which exhibited excellent framework robustness not only in water but also in a wide range of aqueous pH solutions (pH = 2-12). Taking advantage of superior framework robustness and the presence of high-density open metal sites, IITKGP-50 was further explored in catalyzing the two-component Knoevenagel condensation reaction and three-component Strecker reactions. Moreover, to verify the size selectivity of IITKGP-50 , smaller to bulkier substrates in comparison with the MOF's pore cavity (8.1 × 5.6 Å 2 ) were employed, in which relatively lesser conversions for the sterically bulkier aldehyde derivatives confirmed that the catalytic cycle occurs inside the pore cavity. The easy scalability, lower catalyst loading compared to that of benchmark MOFs, magnificent conversion rate over a wide range of substrates, and excellent recyclability without significant performance loss made IITKGP-50 a promising heterogeneous catalyst candidate.

Objectives Placenta previa is characterised as the placenta implant in the lower uterine segment, wholly or partially covering the internal os. Uterine scars from surgical operations are a potential factor of placenta previa. The present study aims to estimate the role of ultrasound in determining the incidence of placenta previa in the scarred and unscarred uterus. Also, it aims to evaluate the types of placenta previa in the scarred and unscarred uterus. Methods This hospital-based, prospective, observational study was performed from September 2021 to August 2022 among patients referred to the Department of Radiology, Fakhruddin Ali Ahmed Medical College and Hospital (FAAMCH), Barpeta, Assam. Written informed consent was obtained from the subjects. Transabdominal and transvaginal ultrasonography methods were used to assess placenta previa. The data analysis was performed using Statistical Package for the Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY) considering a p-value < 0.05 as significant. Results Out of the 517 subjects with bleeding per vagina, 41 (7.9%) were diagnosed with placenta previa by ultrasonography. The mean maternal age was 27.80 ± 5.36 years, and the most prevalent age group was 20-24 years (31.71%). The majority (70.73%) of cases had scarred uterus. The most prevalent placental position was fundo-body anterior. Complete placenta previa was present in 26% of the total cases in the present study. Conclusion The incidence of placenta previa in the scarred uterus was higher than that of the unscarred uterus. The high prevalence of placenta previa in women with scarred uterus necessitates improved monitoring and management to avoid disastrous outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Taye et al.)

The selective and rapid detection of trace amounts of highly toxic chemical warfare agents has become imperative for efficiently using military and civilian defense. Metal-organic frameworks (MOFs) are a class of inorganic-organic hybrid porous material that could be potential next-generation toxic gas sensors. However, the growth of a MOF thin film for efficiently utilizing the material properties for fabricating electronic devices has been challenging. Herein, we report a new approach to efficiently integrate MOF as a receptor through diffusion-induced ingress into the grain boundaries of the pentacene semiconducting film in the place of the most adaptive chemical functionalization method for sensor fabrication. We used bilayer conducting channel-based organic field-effect transistors (OFETs) as a sensing platform comprising CPO-27-Ni as the sensing layer, coated on the pentacene layer, showed a strong response toward sensing of diethyl sulfide, which is one of the stimulants of bis (2-chloroethyl) sulfide, a highly toxic sulfur mustard (HD). Using OFET as a sensing platform, these sensors can be a potential candidate for trace amounts of sulfur mustard detection below 10 ppm in real time as wearable devices for onsite uses.

Aim: To test the efficacy of an integrated microfinance/livelihood and community-based rehabilitation (IMCBR) programme in improving health-related quality of life (HRQoL) and motor function of children with cerebral palsy (CP) and gain in social capital to their ultra-poor families in rural Bangladesh., Method: This was an open-label cluster randomized control trial. Children with CP aged 5 years or under were randomly allocated to three arms; Arm A: IMCBR; Arm B: community-based rehabilitation (CBR); and Arm C: care-as-usual. The CBR was modified with phone follow-up followed by home-based CBR at 2.5 months post-enrolment because of the COVID-19 pandemic. Intention-to-treat analysis was performed., Results: Twenty-four clusters constituting 251 children-primary caregivers' dyads were assigned to three arms (Arm A = 80; Arm B = 82; Arm C = 89). Between baseline and endline, the percentage mean change in the physical functioning domain of HRQoL was highest in Arm A (30.0%) with a significant mean difference between Arm A and Arm B (p = 0.015). Improvement in the mean social capital score was significantly higher in Arm A compared to Arm C (p < 0.001)., Interpretation: The findings suggest that IMCBR could improve the HRQoL of children with CP and the social capital of their ultra-poor families. Long-term follow-up of the trial participants and future exploration of such interventions are essential. The integrated livelihood and CBR programme holds potential to improve health and well-being of children with CP and their ultra-poor families., What This Paper Adds: Half of the families who received livelihoods were impacted by a cold-wave, suggesting the need for a more disaster-resilient livelihood asset. The integration of livelihood with community-based rehabilitation programme helps to improve health-related quality of life of children with cerebral palsy and the social capital of their ultra-poor families., (© 2022 Mac Keith Press.)

Background and Objectives: Currently, we have a shortage of comprehensive information about newer antiepileptic drugs (AEDs) in the pediatric population. This might explain the discrepancies among pediatricians' preferences in this regard. Therefore, it is crucial to study the multifaceted impacts of these drugs on children. The endpoints of our study were non-AED predictors of the requirement of combination therapy for seizure management, seizure-free period >6 months and >12 months, change in Quality of Life in Childhood Epilepsy Questionnaire - 55 (QOLCE-55), and incidence of adverse events., Methods: This prospective, observational study was conducted in KIMS, Bhubaneswar, India, from January 2021 to November 2022. Children of 2-12 years of age were treated with monotherapy of either newer antiepileptics, e.g., levetiracetam, topiramate, and oxcarbazepine or older antiepileptics, e.g., valproic acid, phenytoin, phenobarbital, and carbamazepine. Univariate and multivariate analyses were performed for the assessment of predictors. We used R software (version 4.1.1) for data analysis., Results: One hundred and ninety-eight (91.7%) of 216 enrolled participants completed this study. The mean age of the study population was 5.2 years and 117 (59%) of them were males. The univariate analysis showed that male gender, low birth weight, preterm birth, assisted vaginal delivery and site-specific epilepsy, and maternal history of epilepsy were significant predictors of combination therapy and reduced seizure-free period. There was a non-significant difference regarding the improvement of QOLCE-55 scores. None of the adverse events were serious., Conclusions: Perinatal complications and maternal history of epilepsy contribute significantly toward the efficacy of antiepileptics. However, multivariate analysis did not yield statistically significant results., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Rout et al.)

Adolescents with disability in the Global South have unique sexual and reproductive health (SHR) experiences and needs; however, they are rarely included in SRH discourse. This qualitative study, conducted in rural Bangladesh, used semi-structured interviews to understand how adolescents with cerebral palsy (CP) experience their SRH. Participants were recruited from the Bangladesh Cerebral Palsy Register and included 24 adolescents with CP (n = 12 female; n = 12 male) and 76 parents (n = 56 mothers, n = 17 fathers, n = 3 other relatives). Data were analyzed using reflexive thematic analysis. Findings highlighted heterogeneity among adolescents with CP including differences for adolescent men versus women. For some adolescent men with CP, sexual maturity was viewed as bringing new opportunities, whereas for other men, adolescence affirmed exclusions and some transgressed sociocultural norms as they struggled to navigate their pubescent body alongside new privacy requirements. For adolescent women with CP, sexual maturity was associated with new domestic responsibilities, silence and secrecy regarding menstruation, and increased vulnerability to sexual violence and abuse. Adolescent men and women with CP spoke about marriage as something "everybody wants," however, was deemed "impossible" for those with more impairment-related support needs. Both adolescent men and women with CP lacked access to SRH information and support. Mothers positioned providing care to their adolescent child with CP after puberty as "shameful." Our findings suggest that disability, health, and education services in rural Bangladesh need to adopt a life-course approach that incorporates the SRH of adolescents with CP. We recommend the provision of SRH education that addresses the physical, cognitive, and social needs of adolescents with CP., (© 2023. The Author(s).)

Cost-effective adsorption-based C 2 H 2 /C 2 H 4 and C 2 H 2 /CO 2 gas separations are extremely important in the industry. Herein, a pH-stable three-dimensional (3D) metal-organic framework (MOF), IITKGP-25 , possessing exposed functional sites is presented, which facilitates such separations with excellent ideal adsorbed solution theory (IAST) selectivity (4.61 for C 2 H 2 /C 2 H 4 and 3.93 for C 2 H 2 /CO 2 ) under ambient conditions (295 K, 100 kPa, 50:50 gas mixtures) and a moderate affinity toward C 2 H 2 (26.6 kJ mol -1 ). Interestingly, IITKGP-25 can maintain structural integrity in water and in aqueous acidic/alkaline (pH = 2-10) medium because of the higher coordination numbers around the metal center and the hydrophobicity of the ligand. The adsorption capacity for C 2 H 2 remains unchanged for a minimum of up to five consecutive cycles and 15 days of exposure to 97% relative humidity, which are the prerequisites of an adsorbent for practical gas separation application. Density functional theory (DFT) calculations reveal that the open Cd(II) sites and carboxylate oxygen-coordinated Cd(II) corner of the triangle-shaped one-dimensional (1D) channel are the enthalpically more preferred binding sites for C 2 H 2 , which stabilize the adsorbed C 2 H 2 through nonlocal stronger H-bonding and also pπ-dπ and CH-π interactions.

Trivalent metal ions (Cr 3+ , Al 3+ , and Fe 3+ ) constitute a major section of the environmental pollutants, and their excess accumulation has a detrimental effect on health, so their detection in trace quantity has been a hot topic of research. A highly scalable 3D porous Zn-based luminescent metal-organic framework (MOF) has been synthesized by exploiting the mixed ligand synthesis concept. The strategic selection of an aromatic π-conjugated organic linker and N-rich spacer containing the azine functionality as metal ion binding sites immobilized across the pore spaces, have made this MOF an ideal turn-on sensor for Al 3+ , Cr 3+ , and Fe 3+ ions with very high sensitivity, selectivity, and recyclability. An in-depth study revealed absorbance caused enhancement mechanism (ACE) responsible for such turn-on phenomena. In order to make the detection process straightforward, convenient, portable, and economically viable, we have fabricated MOF test paper strips (the MOF could be simply immobilized onto the paper strips) for naked eye visual detection under UV light, which, thus, manifests its potential as a real-time smart sensor for these trivalent ions.

Cell Surface hydrophobicity is one of the determinant biophysical parameters of bacterial aggregation for being networked to form a biofilm. Phytoconstituent, like vitexin, has long been in use for their antibacterial effect. The present work demonstrates the role of vitexin in modulating Staphylococcus aureus surface hydrophobicity while aggregating to form biofilm and pathogenesis in a host. In planktonic form, vitexin shows minimum inhibitory concentration at 252 µg/ml against S. aureus. Sub-MIC doses of vitexin and antibiotics (26 µg/ml of vitexin, 55 µg/ml of azithromycin, and 2.5 µg/ml of gentamicin) were selected to treat S. aureus. Dead cell counts after treatment were studied through flow cytometry. As dead cell counts were minimal (<5 %), these doses were considered for all subsequent experiments. While studying aggregating cells, it was observed that vitexin reduces S. aureus surface hydrophobicity and membrane permeability at the sub-MIC dose of 26 µg/ml. The in silico binding analysis showed a higher binding affinity of vitexin with surface proteins (IcaA, DltA, and SasG) of S. aureus. Down-regulation of dltA and icaAB expression, along with the reduction in membrane potential with a sub-MIC dose of vitexin, explains reduced S. aureus surface hydrophobicity. Vitexin was found to interfere with S. aureus biofilm-associated protein biomass, EPS production, and swarming movement. Subsequently, the suppression of proteases production and down-regulation of icaAB and agrAC gene expression with a sub-MIC dose of vitexin explained the inhibition of S. aureus virulence in vitro. Besides, vitexin was also found to potentiate the antibiofilm activity of sub-MIC doses of gentamicin and azithromycin. Treatment with vitexin exhibits a protective response in S. aureus infected macrophages through modulation of expression of cytokines like IL-10 and IL-12p40 at protein and mRNA levels. Furthermore, CFU count and histological examination of infected mouse tissue (liver and spleen) justify the in vivo protective effect of vitexin from S. aureus biofilm-associated infection. From this study, it can be inferred that vitexin can reduce S. aureus surface hydrophobicity, leading to interference with aggregation at the time of biofilm formation and subsequent pathogenesis in a host., (Copyright © 2022 Elsevier GmbH.

Purpose: Rehabilitation needs are rising globally; however, the rate is strikingly higher in low- and middle-income countries (LMICs). Like many LMICs, the situation of rehabilitation services for persons with disabilities (PwDs) in Bangladesh is mostly unknown. We assessed the current situation of rehabilitation services for PwDs in Bangladesh., Materials and Methods: This mixed-method study incorporated an online survey of rehabilitation service providers and a scoping review of documents published on rehabilitation services for PwDs in Bangladesh. Descriptive and thematic analyses were completed., Results: A total of 1102 rehabilitation service providers were interviewed, and 36 documents were reviewed. Rehabilitation services for PwDs were found not integrated into the mainstream health services, financing mechanisms, information systems, and health policies in Bangladesh. There are 6.8 rehabilitation units for 1 million people, and 6.2% of them are located in rural areas. In terms of the rehabilitation workforce, there are 9.4 physiotherapists, 1.3 occupational therapists, 0.9 speech and language therapists, and 0.2 prosthetist and orthotists for 1 million people in Bangladesh. Majority (66.3%) of rehabilitation services require an out-of-pocket payment., Conclusions: A critical shortage and uneven distribution of the rehabilitation workforce are evident, indicating a likelihood of very high unmet rehabilitation needs in Bangladesh. To strengthen the rehabilitation capacity of Bangladesh, rehabilitation services should be integrated into mainstream health policies and programs with a special focus on the rehabilitation workforce training, recruitment and distribution, and allocation of resources.Implications for rehabilitationRehabilitation services in Bangladesh are mostly provided by the private sector, although the government of Bangladesh operates a small number of rehabilitation services outside of the mainstream public health service delivery system.Rehabilitation services are lacking in the primary and secondary health facilities, while services at tertiary level public hospitals are mainly provided by medical technologists in the absence of a qualified rehabilitation workforce.A severe shortage of rehabilitation workforce coupled with an uneven distribution of the existing limited number of rehabilitation services and out-of-pocket expenditures might result in inadequate access and poor rehabilitation service uptake amongst persons with disabilities (PwDs) in Bangladesh.Robust governance and leadership are needed to monitor the implementation of existing legislations and policies and develop strategies to improve the situation of rehabilitation services for PwDs in Bangladesh.

The development of chemically stable metal-organic framework (MOF)-based luminescent platforms for toxic ion detection in an aqueous medium is highly challenging because most of the classical MOFs are prone to water degradation, and that is the reason why most of the MOF-based luminescent sensors use a nonaqueous medium for sensing. In this contribution, we report two new water-stable luminescent MOFs (Zn-MOF-1 and Zn-MOF-2), assembled from a mixed-ligand synthesis approach. Because of the presence of a hydrophobic trifluoromethyl group to the backbone and stronger metal-N coordination, these MOFs exhibit excellent stability not only in water but also in acidic/alkaline aqueous solutions (pH = 3-10). Here, we report a green sensing approach by exploiting the significant reduction in photoluminescence of these MOFs in the presence of toxic ions. Fe 3+ and CrO 4 2- /Cr 2 O 7 2- ions could be traced with a detection limit (LOD) in the micromolar range (0.045 and 0.745/0.33 μM for Zn-MOF-1; 125.2 and 114.2/83.5 μM for Zn-MOF-2). The mechanistic study reveals that competitive absorption of the excitation energy coupled with fluorescent resonance energy transfer are responsible for the turn-off quenching. The anti-interference ability and recyclability along with the pH stability gave these MOFs high potential to be used as practical sensors toward Fe III and Cr VI ions in water as a greenest medium.

Mass testing for COVID-19 infection is one of the core measures in tackling the global spread of the disease. Testing is vital to diagnose and estimate cases, attack rates and case fatality rates- critical data for policy-making. As COVID-19 continues to spread globally, the demand for more extensive laboratory testing and innovative technology increases. However, countries around the world have been struggling to keep up pace with the worldwide demand to expand testing strategy. The pandemic evolves, so does our knowledge and understanding of diagnostic tests of COVID-19. Here we aim to review major challenges related to COVID-19 diagnostic tests and future development. So, the ongoing urgency and demand for tests would certainly steer the rapid uptake of novel techniques, which in turn would boost our understanding of diagnostic tests for COVID-19.

Background: Children are very much vulnerable to adverse drug reactions (ADRs) and also tend to have more severe form of adverse effects compared to adults. Though ADR is a significant problem in children, paediatricians seem to neglect this aspect. Knowledge, attitude and practice (KAP) studies related to pharmacovigilance among paediatricians are lacking in literature. Hence, this study was planned to know the gaps in KAP among paediatricians of Odisha and factors related to underreporting of ADR., Materials and Methods: Google Form containing the questions was shared to paediatricians of Odisha state working in both private and government organisations. The questionnaire was prepared based on previous studies and some new questions relevant to our scenario were added. The questionnaire contained six questions based on knowledge, four on attitude and three on practice of ADR. Apart from that, it contained questions to know their response regarding the factors that discourage paediatricians to report ADRs. There were 60 responses., Results: Among the paediatricians, 70%-80% were aware of the pharmacovigilance programme running in India. Also, 80%-90% agreed that ADR reporting is crucial in paediatric health care, while most of them were trained regarding ADR reporting. But only 50% of them had reported an ADR in their clinical practice, which clearly indicates towards underreporting., Conclusion: The motivation for voluntary reporting of ADRs among paediatricians for preventing the morbidity and mortality in this vulnerable population could be of immense importance, and hence, various workshops and CMEs should be conducted to improve the KAP of these doctors, so that the problem of underreporting could be minimised., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Family Medicine and Primary Care.)

Objective: To define the prevalence and seizure subtypes among children with cerebral palsy (CP) in rural Bangladesh and explore barriers to optimum epilepsy control., Design: Prospective cohort study., Setting: The study was conducted in Shahjadpur, a rural subdistrict of Bangladesh., Participants: Children (<18 years) with CP and epilepsy identified using the Bangladesh CP Register (BCPR) in the study site., Methods: Assessments were conducted in three focused epilepsy clinics overseen by a paediatric neurologist between December 2016 and January 2018, with intervening phone and video-conference follow-ups. Details of event type, frequency and medication compliance were collected. Antiepileptic drugs (AEDs) were prescribed based on seizure type, family income, comorbidity and medication availability., Results: 23.4% (170/726) of the BCPR cohort had a clinical diagnosis of epilepsy of whom 166 were assessed. Following the focused epilepsy clinics, 62.0% (103/166) children were clinically determined to have ongoing epileptic seizures. 62.1% (64/103) had generalised onset tonic clonic seizures, 27.2% (28/103) had focal onset seizures with impaired awareness and 10.7% (11/103) had other seizure types. None of the children with prolonged seizures (31/103) had an emergency seizure management plan. Non-epileptic events were being pharmacologically treated as seizures in 18.1% (30/166) children. Financial constraints were the main reason for non-compliance on follow-up., Conclusions: Gaps in optimum epilepsy management in rural Bangladesh are amenable to improvement anchored with local healthcare workers. Training and clinical care focused on recognition of common seizure types, seizure mimics and rationalising use of available AEDs can be facilitated by better referral pathways and telehealth support., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: Malnutrition is substantially higher among children with cerebral palsy (CP) in low- and middle-income countries (LMICs) when compared with the general population. Access to appropriate interventions is crucial for better management of malnutrition and nutritional outcomes of those children. We aimed to review the existing evidence on nutrition interventions for children with CP in LMICs., Methods: Online databases, i.e., PubMed and Scopus, and Google Scholar were searched up to 10 January 2022, to identify peer-reviewed publications/evidence on LMIC focused nutritional management guidelines/interventions. Following title screening and abstract review, full articles that met the inclusion/exclusion criteria were retained for data charting. Information about the study characteristics, nutrition interventions, and their effectiveness were extracted. Descriptive data were reported., Results: Eight articles published between 2008 and 2019 were included with data from a total of n = 252 children with CP (age range: 1 y 0 m-18 y 7 m, 42% female). Five studies followed experimental design; n = 6 were conducted in hospital/clinic/center-based settings. Four studies focused on parental/caregiver training; n = 2 studies had surgical interventions (i.e., gastrostomy) and n = 1 provided neurodevelopmental therapy feeding intervention. Dietary modification as an intervention (or component) was reported in n = 5 studies and had better effect on the nutritional outcomes of children with CP compared to interventions focused on feeding skills or other behavioral modifications. Surgical interventions improved nutritional outcomes in both studies; however, none documented any adverse consequences of the surgical interventions., Conclusion: There is a substantial knowledge gap on nutrition interventions for children with CP in LMICs. This hinders the development of best practice guidelines for the nutritional management of children with CP in those settings. Findings suggest interventions directly related to growth/feeding of children had a better outcome than behavioral interventions. This should be considered in planning of nutrition-focused intervention or comprehensive services for children with CP in LMICs.

Background: Despite the high burden of childhood disability in low-and middle-income countries (LMICs), the opportunity for early intervention and rehabilitation is very limited. Studies have found that community-based rehabilitation service is effective for children with cerebral palsy (CP); however, such services are not readily available in LMICs, and services run by non-profit organisations on external funding are often not sustainable. In this study, we report the lesson learnt in establishing a social business model of early intervention and rehabilitation services for children with CP and adults with disabilities in a rural subdistrict of Bangladesh., Methods: Case study of a rural early intervention and rehabilitation centre (i.e., the model centre) implemented between May 2018 and September 2019. An economic evaluation incorporating gross margin analysis along with descriptive statistics was performed to assess the social business potentials of the model centre., Results: The establishment of this model centre cost ~5955 USD with an average monthly running cost of ~994 USD. During the 17 months study period, 7038 therapy sessions (average eight sessions per patient) were offered to 862 patients with musculoskeletal and neurological disorders. The most common clinical presentations were low back pain (35.6%; n = 307). Six percent ( n = 52) of the attendees were children with CP (mean (SD) age 6.3 (4.0) years; 35.7% ( n = 19) were female), who received 1392 sessions, on average 27 sessions per child. The centre reached the break-even point at the 13th month and remained profitable for the next 4 months of the study period. An average session fee of 2.2 USD resulted in a gross margin of -1458 USD and 1940 USD in 2018 and 2019, respectively. Revenue to cost ratios for the 2 years were 0.27:1 and 0.51:1 while average rates of return were -41.4% and 10.1%, respectively. Sensitivity analysis revealed that session numbers including 5000, 6000, 7000, 8000, 9000, and 10,000 were required to break even at the session fees of 3.0, 2.50, 2.0, 2.0, 1.5, and 1.5 USD, respectively., Conclusion: Our social business model of an early intervention and rehabilitation service provides evidence of enhancing access to services for children with CP as well as adults with disabilities while ensuring the sustainability of the services in rural Bangladesh.

Aim: To describe the epidemiology of eye diseases among children with disability in rural Bangladesh., Method: We established a population-based cohort of children with disability using the key informant method. Children younger than 18 years with disability (i.e. physical, visual, hearing, speech, epilepsy) were included. We used detailed ophthalmological assessments following World Health Organization (WHO) protocols by a multidisciplinary team including an ophthalmologist, optometrist, physician, and physiotherapist. Visual impairment, blindness, and severe visual impairment (SVI) were defined by following WHO categories., Results: Between October 2017 and February 2018, 1274 children were assessed (43.6% female; median [interquartile range] age 9y 10mo [6y -13y 7mo]). Overall, 6.5% (n=83) had blindness/SVI, and 5.6% (n=71) had visual impairment. In the group with blindness/SVI, 47% (n=39) had cortical blindness; of those, 79.5% (n=31) had cerebral palsy (CP). The other main anatomical sites of abnormalities in this group included lens (13.3%, n=11), cornea (10.8%, n=9), and optic nerve (9.6%, n=8). In the group with visual impairment, 90.1% (n=64) had refractive error. Overall, 83.1% (n=69) and 78.8% (n=56) of those with blindness/SVI and visual impairment had avoidable causes. Most children with blindness/SVI and visual impairment lacked access to education., Interpretation: The burden of blindness/SVI/visual impairment is high among children with disability in rural Bangladesh, mostly due to avoidable causes. Overrepresentation of CP and cortical blindness in the group with blindness/SVI and refractive error in the group with visual impairment highlights the need for integration of ophthalmology assessment, eye care, and refraction services in comprehensive health care for children with disability including CP in rural Bangladesh., (© 2021 Mac Keith Press.)

Multidrug resistance mechanism of microorganisms towards conventional antimicrobials nowadays faces a common health problem. So, searching and development of new antibacterials are in the frontier areas of biochemistry. Functionalizations of various natural products or synthesis of compounds through molecular modeling followed by virtual screening are the ways to obtain potential leads. Chrysin is one of the plant secondary metabolites and is ubiquitously present in majority of plants. It has multi-dimensional potentiality however, with a very low bioavailability causing a very low efficacy. Very few chrysin derivatives possessing antimicrobial activity with a low anti-biofilm efficacy have been found in the literature. Thus, it has been attempted to synthesize a series of new chrysin derivatives (CDs). In this study, twenty-two new derivatives have been synthesized via its 7-OH modulation and antibiofilm activity was evaluated against a model bacterium viz. Escherichia coli MTCC 40 (Gram negative). Eleven CDs coded as 2a, 2b, 2c, 2e, 2f, 2g, 2h, 2i, 3j, 3k and 3l have been found more potent compared to chrysin (precursor of CDs) against planktonic form of E. coli. Biofilm inhibition studies indicated a noteworthy results for 2a (93.57%), 2b (92.14%), 2f (92.14%) and 3l (93.57%) compared to chrysin (33.57%). E. coli motility was also highly restricted by 2a, 2b, 2f and 3l than chrysin at their sub-inhibitory concentrations. Solubility studies indicated an extended-release of 2a, 2b, 2f and 3l in physiological systems. Relatively higher bioavailability of 2a, 2b, 2f and 3l than chrysin was revealed from the dissolution experiments and was further validated through in silico ADME-based SAR analysis. Hence, this study is more interesting in regard to antibacterial potentiality of chrysin derivatives against Escherichia coli MTCC 40 (Gram negative). Thus, this article might be useful for further design and development of new leads in the context of biofilm-associated bacterial infections., (© 2021.

Introduction: Poverty is a key contributor to delayed diagnosis and limited access to early intervention and rehabilitation for children with cerebral palsy (CP) in rural Bangladesh. 97% of families of children with CP live below the poverty line in Bangladesh. Therefore, in low-and middle-income countries (LMICs), efforts to improve outcomes for children with CP (including health-related quality of life, motor function, communication, and nutritional attainments) should also include measures to improve family economic and social capital. We propose a randomised controlled trial (RCT) to evaluate the effectiveness of an integrated microfinance/livelihood and community-based rehabilitation (IMCBR) program for ultra-poor families of children with CP in rural Bangladesh., Material and Methods: This will be a cluster RCT comparing three arms: (a) integrated microfinance/livelihood and community-based rehabilitation (IMCBR); (b) community-based rehabilitation (CBR) alone; and (c) care-as-usual (i.e. no intervention). Seven clusters will be recruited within each arm. Each cluster will consist of 10 child-caregiver dyads totalling 21 clusters with 210 dyads. Parents recruited in the IMCBR arm will take part in a microfinance/livelihood program and Parent Training Module (PTM), their children with CP will take part in a Goal Directed Training (GDT) program. The programs will be facilitated by specially trained Community Rehabilitation Officers. The CBR arm includes the same PTM and GDT interventions excluding the microfinance/livelihood program. The care-as-usual arm will be provided with information about early intervention and rehabilitation. The assessors will be blinded to group allocation. The duration of the intervention will be 12 months; outcomes will be measured at baseline, 6 months, 12 months, and 18 months., Conclusion: This will be the first RCT of an integrated microfinance/livelihood and CBR program for children with CP in LMIC settings. Evidence from the study could transform approaches to improving wellbeing of children with CP and their ultra-poor families., Competing Interests: The authors have declared that no competing interests exist.

Background: Ensuring water, sanitation, and hygiene (WASH) facilities for households remains a major public health concern in low- and middle-income countries (LMICs). This study investigated the current situation of basic WASH facilities for households in Bangladesh and drew a national coverage map., Methods: We analyzed the publicly available nationally representative 2019 Multiple Indicator Cluster Survey (MICS) dataset that was carried out by the Bangladesh Bureau of Statistics (BBS) with support from the United Nations Children's Emergency Fund (UNICEF). A total of 61,209 households (weighted) were included in the analysis. Both bivariate and multivariate analyses were employed to examine the relationships between independent variables (socio-demographic and economic status) and their distributions over outcome variables (basic water, sanitation, and hygiene). Further, the spatial distribution of WASH facilities at the household level was depicted., Results: Coverage of access to basic water facilities at the household level was 99.5% (95% CI 99.4% to 99.6%), sanitation 60.7% (95% CI 60.0% to 61.5%), and hygiene 56.3% (95% CI 55.6% to 57.0%). However, coverage of combined access to all three components was 40.2% (95% CI 39.4% to 40.9%). Among all 64 administrative districts of Bangladesh, we found comparatively lower coverage of WASH facilities in the South and South-East regions and relatively higher in the households of the North and North-Western regions. An adjusted regression model revealed that richest households [AOR = 29.64, 95% CI 26.31 to 33.39], households in the rural areas [AOR = 1.64, 95% CI 1.50 to 1.79], household heads with higher educational attainment [AOR = 2.28, 95% CI 2.09 to 2.49], and households with 5+ family members [AOR = 1.64, 95% CI 1.56 to 1.71] had the higher likelihood to have basic WASH facilities., Conclusion: Less than half of the Bangladeshi households had access to all three major WASH components (basic water, sanitation, and hygiene facilities); however, variation exists at the individual parameter of basic water, sanitation, and hygiene facilities. A comprehensive WASH approach may reduce the gap and improve the quality of WASH facilities in Bangladesh., Competing Interests: The authors have declared that no competing interests exist.

The family Orchidaceae, with over 25,000 species, includes five subfamilies and nearly 700 genera. Loss of plants in the wild has resulted from clearing of forests and excessive collection for various purposes. Moreover, the requirement of symbiotic association during seed germination under natural conditions adds a certain level of difficulty in retaining the orchid resources in the wild. Cryopreservation is an important arena in conservation science due to its potential of storing genetic resources without altering the genetic makeup. Cryopreserved orchids are a very small percentage of the species, and are also not representative of most genera. Finding effective protocols for the various explant types is of prime importance in conserving orchid diversity. Seed is the most commonly stored and directly useful explant, and direct plunging in liquid nitrogen or PVS2 vitrification appear to be suitable for most tested species. The myriad of other species should be screened as they become available, with special emphasis on seed maturity and moisture content. Studies of protocorms and protocorm-like bodies mostly employ desiccation, PVS2 vitrification or encapsulation-dehydration. Pollinia are generally stored successfully following desiccation or slow cooling. There are too few examples of shoot tip cryopreservation to make a determination, however vitrification techniques are likely the most useful for a range of genera. A systematic and coordinated effort is needed to screen all available species in as many taxa as possible, initially with seed, protocorms and pollinia. It is a charge to the orchid research community to organize this effort and fill in the required data for the large number of untested taxa. In addition, providing stored samples to established orchid cryo collections would greatly increase preservation of these endangered treasures., (Copyright © 2021 Elsevier Inc. All rights reserved.)

In medical consultations, the length of the visit has a significant impact on the quality of care. It is significantly associated with a better quality of treatment and better health outcomes. In this study, we analyzed doctors' consultation length with patients and associated factors in Bangladesh. A cross-sectional survey was conducted among the patients (N = 763) who visited the doctors in six district/upazila (sub-district) hospitals in the Chittagong Hill Tracts (CHT) area. Linear regression analyses were performed to identify the determining factors associated with the length of doctors' appointments with patients. Data were analyzed using IBM SPSS version 24.0. Among the patients, 319 (41.8%) were female and 688 (90.2%) lived in rural/suburban areas. This study revealed that the average length of medical consultations was 9.10 min. Additionally, our findings illustrated that doctors' patient-centered communication behavior (β = 0.23, p < 0.001) appeared to be the strongest predictor of longer visit length. It was also found that patients' higher education level (β = 0.10, p = 0.006), having adequate knowledge about the health problem (β = 0.13, p < 0.001), follow-up visits (β = 0.13, p < 0.001), and the presence of female doctors (β = 0.19, p < 0.001) were significantly associated with longer interview times between doctors and patients in primary care settings. Given that doctors' patient-centered communication behavior appears to play the most important role, this study suggests that practicing professionalism in medical consultations, developing effective communication skills and increasing awareness of sociodemographic discrepancies are important to ensure longer appointment lengths and better health outcomes of patients, regardless their sociodemographic and socioeconomic status.

Accumulation of high concentrations of Al(III) in body has a direct impact on health and therefore, the trace detection of Al(III) has been a matter for substantial concern. An anionic metal organic framework ({[Me 2 NH 2 ] 0.5 [Co(DATRz) 0.5 (NH 2 BDC)] ⋅ xG} n ; 1; HDATRz=3,5-diamino-1,2,4-triazole, H 2 NH 2 -BDC=2-amino-1,4-benzenedicarboxylic acid, G=guest molecule) composed of two types of secondary building units (SBU) and channels of varying sizes was synthesized by employing a rational design mixed ligand synthesis approach. Free -NH 2 groups on both the ligands are immobilized onto the pore surface of the MOF which acts as a superior luminescent sensor for turn-on Al(III) detection. Furthermore, the large channels could allow the counter-ions to pass through and get exchanged to selectively detect Al(III) in presence of other seventeen metal ions with magnificent luminescence enhancement. The observed limit of detection is as low as 17.5 ppb, which is the lowest among the MOF-based sensors achieved so far. To make this detection approach simple, portable and economic, we demonstrate MOF filter paper test for real time naked eye observation., (© 2021 Wiley-VCH GmbH.)

Aim: To assess the burden and underlying factors of malnutrition among children with cerebral palsy (CP) in the remote Sumba Island, Indonesia., Methods: This is a community-based key informant (KI) method survey of children with CP in the southwest regency of Sumba Island, Indonesia (child population∼152 471). Children with suspected CP identified by trained community volunteers (KIs) underwent a detailed neurodevelopmental assessment by a multidisciplinary medical assessment team to confirm diagnosis of CP. Anthropometric measurements were taken, z scores were calculated, and nutritional status was determined following the World Health Organization guideline. Descriptive analyses were performed, multivariable linear regression model was fitted to identify potential predictors of malnutrition., Results: One hundred and thirty children with CP aged <18 years were included in the study. The majority were severely underweight (78.8%) and severely stunted (85.9%). Severe malnutrition was overrepresented among young children, children who had spastic tri/quadriplegia, Gross Motor Function Classification System levels III-V, had at least one associated impairment, speech impairment and/or swallowing difficulties. Age and presence of visual impairment were found to be significantly associated with weight-for-age z score (i.e., underweight) whereas, epilepsy was significantly associated with the height-for-age z score (i.e., stunting) when adjusted for other covariates., Conclusions: The substantial-high burden of malnutrition among children with CP in remote Sumba Island highlights their vulnerability to poor health-related outcomes. There is an urgent need for nutritional rehabilitation services to avert such consequences among children with CP in low and middle-income countries like Indonesia.Implications for rehabilitationMalnutrition among children with cerebral palsy (CP) is alarmingly high in the remote Sumba island of Indonesia.Children with severe gross motor function limitations or spastic tri/quadriplegia had the most severe malnutrition.There is an urgent need for rehabilitation services including nutrition and feeding interventions for children with CP in low and middle-income countries like Indonesia.

Objective: The objective of this study was to assess the rehabilitation status and factors associated with rehabilitation service utilisation among children with cerebral palsy (CP) in Bangladesh., Materials and Methods: This is a population-based surveillance study conducted among children with CP registered in the Bangladesh CP Register (BCPR), the first population-based register of children with CP aged <18 years (y) in Bangladesh. Children with CP were identified from the community using the key informant method and underwent a detailed neurodevelopmental assessment. Socio-demographic, clinical and rehabilitation status were documented. Unadjusted and adjusted analyses with a 95% confidence interval (CI) were used to identify potential predictors of rehabilitation service uptake., Results: Between January 2015 and December 2019, 2852 children with CP were registered in the BCPR (mean (standard deviation, SD) age: 7 y 8 months (mo) (4 y 7 mo), 38.5% female). Of these, 50.2% had received rehabilitation services; physiotherapy was the most common type of service (90.0%). The mean (SD) age at commencement of rehabilitation services was 3 y 10 mo (3 y 1 mo). The odds of not receiving rehabilitation was significantly higher among female children (adjusted odds ratio (aOR) 1.3 [95% CI: 1.0-1.7], children whose mothers were illiterate and primary level completed (aOR 2.1 [95% CI: 1.4-3.1] and aOR 1.5 [95% CI: 1.1-2.1], respectively), fathers were illiterate (aOR 1.9 [95% CI: 1.3-2.8]), had a monthly family income ~US$ 59-118 (aOR: 1.8 [95% CI: 1.2-2.6]), had hearing impairment (aOR: 2.3 [95% CI: 1.5-3.5]) and motor severity (i.e. Gross Motor Function Classification System level III (aOR: 0.6 [95% CI: 0.3-0.9]) and level V (aOR: 0.4 [95% CI: 0.2-0.7]))., Conclusions: Rehabilitation status was poor among the majority of the children with CP in the BCPR cohort, limiting their opportunities for functional improvement. A community-based rehabilitation model focusing on socio-demographic and clinical characteristics should be a public health priority in Bangladesh., Competing Interests: The authors declare that there is no conflict of interest.

Background: As there is paucity of exclusive literature on pediatric hepatic Wilson's disease (WD), this study was undertaken to evaluate the efficacy of chelation on hepatocellular function and portal hypertension in WD., Methods: Wilson's disease patients with ≥9 months of follow-up were evaluated for response to chelation therapy in the following categories: (a) complete remission, (b) partial remission (c) progression of disease; (d) drug toxicity. Pediatric end-stage liver disease (PELD), Nazar and New Wilson Index scores were compared. Hemodynamically stable patients underwent esophagogastroduodenoscopy (baseline and surveillance) and received prophylaxis (primary or secondary). Endoscopic outcome was assessed at follow-up., Results: Of the 111 WD children (aged 9 [3-15] years; PELD score 16 [-11 to 60]), 65 with follow-up of 3.6 (0.8-12) years on chelation (83% D-penicillamine monotherapy, 17% D-penicillamine and zinc) were analyzed. 81% had severe disease at presentation. Favorable outcome (complete and or partial remission), progression of disease and drug toxicity were seen in 71%, 29% and 10.8%, respectively. Two-thirds had esophageal varices which did not show progression. Large esophageal varices (16%) were effectively downgraded in 3 (2-6) therapeutic endoscopic sessions. Nazar score and PELD score at baseline were independent predictors of outcome with favorable correlation with each other (r = .864, P < .001). PELD cutoff 9.45 (AUC: 71%, sensitivity: 87%, specificity: 50%; P = .009) and Nazar score cut off 3.5 (AUC: 68%, sensitivity: 83%, specificity: 50%; P = .02) were associated with poor prognosis., Conclusions: Despite severe liver disease, the majority of hepatic WD can be managed on D-penicillamine monotherapy. PELD score and Nazar score effectively determine the outcome., (© 2020 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

The coronavirus disease 2019 (COVID-19), first reported in Wuhan, China is now a major global health threat - a pandemic. Public health control measures are the cornerstones in the fight against COVID-19 in the absence of an effective vaccine or proven treatment. The aim of this review was to explore the historical use case of various public health measures adopted today to tackle COVID-19 spread. Although our knowledge about this novel coronavirus transmission is evolving over time, the fundamental non-pharmaceutical interventions e.g., handwashing, wearing a mask, physical distancing, isolation, quarantine and border control which are adopted globally at present are not new. This review highlighted that historically and religiously similar approaches were practised in the medieval past for controlling disease outbreaks. The successful implementation of the public health control measures largely depends on health systems resilience, community engagement and changes in population behaviour. Combined global efforts are essential to strengthen health systems, improve the capability of research and transparent information sharing with both public and international bodies to combat the pandemic.

Leishmania donovani, a protozoan parasite, inflicts the disease Visceral leishmaniasis (VL) Worldwide. The only orally bioavailable drug miltefosine is toxic, whereas liposomal amphotericin B (AmpB) is expensive. Lupeol, a triterpenoid from Sterculia villosa bark, was exhibited immunomodulatory and anti-leishmanial activity in experimental VL. Herein, we evaluated synergism between sub-optimum dose of AmpB and lupeol in anti-leishmanial and immunomodulatory effects in L. donovani-infected BALB/c mice. We observed that a combination of sub-optimum dose of lupeol and AmpB significantly reduced the hepatic and splenic parasitic burden accompanied by enhanced nitric oxide production, robust induction of Th1 cytokines (IL-12 and IFN-γ) but suppressed Th2 cytokine (IL-10 and TGF- β) production. The treatment with the lupeol-AmpB combination enhanced p38mitogen-activated protein kinase (p38MAPK), but reduced extracellular signal-related kinase (ERK-1/2), phosphorylation and up-regulated pro-inflammatory response. The present work thus indicates a lupeol-AmpB-mediated immunotherapeutic approach for eliminating the parasite-induced immunosuppression., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Introduction and Aim: Delayed referral of neonatal cholestasis (NC) can result in significant morbidity and mortality. In this multi-center study, we aimed to evaluate the reliability of the stool card in the Indian population and develop an integrated NC card with (a) urine color identification and (b) stool color for early referral., Methods: Consecutive children with NC were enrolled and divided into two groups (biliary atresia [BA] and non-BA). Normal healthy children at 6-8 weeks of age served as controls. Each photograph of stool and urine samples of every child was evaluated by 6 parents, 6 paramedical staff, and 4 trainee doctors using a stool color card as a reference for stool samples., Results: Of 319 children (BA [n = 58], non-BA [n = 62], and controls [n = 199]), parents correctly detected dark yellow urine in all NC. Stool samples of 50 (86%) children with BA were unanimously labeled as pale by all observers. The average inter-item correlation showed good correlation between parents and trainee doctors of 0.77 and 0.64 with paramedical staff., Conclusion: The integrated NC card proposes to recognize neonatal cholestasis at an early stage irrespective of etiology. It is a major step towards public health benefit both at the community as well as physicians' levels to enable early detection and timely referral and management.

Aim: To define the epidemiology, clinical characteristics, and rehabilitation status of children with cerebral palsy (CP) in Sumba Island, Indonesia., Method: A community-based key informant method survey among children (aged <18y) with CP was conducted between March and August 2017. Children with suspected CP underwent detailed neurodevelopmental assessment by a multidisciplinary medical team. Socio-demographic characteristics, aetiology, motor type, motor severity, associated impairments, educational, and rehabilitation status were documented., Results: There were 130 children with clinically confirmed CP. The mean age at assessment was 8 years 11 months and 43.8% (n=57) of the children were female. The mean age at CP diagnosis was 6 years 5 months. Of these children, 46.9% (n=61) had post-neonatally acquired CP, most frequently because of vaccine-preventable infectious encephalopathy (73.8%, n=45). In total, 80.8% (n=105) had a predominantly spastic motor type of CP and 83.8% (n=109) were classified in Gross Motor Functional Classification System levels III to V. A total of 77.7% (n=101) had at least one associated impairment (speech 77.5%, intellectual 29.2%, visual 13.8%, hearing 20.0%, and epilepsy 13.5%). And 66.2% (n=86) had never received rehabilitation services., Interpretation: Post-neonatally acquired CP was common in this setting. Addressing preventable post-neonatally acquired risk factors for CP should be a public health priority. Earlier identification and diagnosis of CP would also provide new opportunities for early intervention and targeted rehabilitation services., (© 2020 Mac Keith Press.)

The design and construction of "thermodynamically stable" metal-organic frameworks (MOFs) that can survive in liquid water, boiling water, and acidic/basic solutions over a wide pH range is highly desirable for many practical applications, especially adsorption-based gas separations with obvious scalable preparations. Herein, a new thermodynamically stable Ni MOF, {[Ni(L)(1,4-NDC)(H 2 O) 2 ]} n (IITKGP-20; L=4,4'-azobispyridine; 1,4-NDC=1,4-naphthalene dicarboxylic acid; IITKGP stands for the Indian Institute of Technology Kharagpur), has been designed that displays moderate porosity with a BET surface area of 218 m 2  g -1 and micropores along the [10-1] direction. As an alternative to a cost-intensive, cryogenic, high-pressure distillation process for the separation of hydrocarbons, MOFs have recently shown promise for such separations. Thus, towards an application standpoint, this MOF exhibits a higher uptake of C 2 hydrocarbons over that of C 1 hydrocarbon under ambient conditions, with one of the highest selectivities based on the ideal adsorbed solution theory (IAST) method. A combination of two strategies (the presence of stronger metal-N coordination of the spacer and the hydrophobicity of the aromatic moiety of the organic ligand) possibly makes the framework highly robust, even stable in boiling water and over a wide range of pH 2-10, and represents the first example of a thermodynamically stable MOF displaying a 2D structural network. Moreover, this material is easily scalable by heating the reaction mixture at reflux overnight. Because such separations are performed in the presence of water vapor and acidic gases, there is a great need to explore thermodynamically stable MOFs that retain not only structural integrity, but also the porosity of the frameworks., (© 2020 Wiley-VCH GmbH.)

The stability of microporous metal-organic frameworks (MOFs) in moist environments must be taken into consideration for their practical implementations, which has been largely ignored thus far. Herein, we synthesized a new moisture-stable Zn-MOF, {[Zn 2 (SDB) 2 (L) 2 ]·2DMA} n , IITKGP-12 , by utilizing a bent organic linker 4,4'-sulfonyldibenzoic acid (H 2 SDB) containing a polar sulfone group (-SO 2 ) and a N, N-donor spacer ( L ) with a Brunauer-Emmett-Teller surface area of 216 m 2 g -1 . This material displays greater CO 2 adsorption capacity over N 2 and CH 4 with high IAST selectivity, which is also validated by breakthrough experiments with longer breakthrough times for CO 2 . Most importantly, the separation performance is largely unaffected in the presence of moisture of simulated flue gas stream. Temperature-programmed desorption (TPD) analysis shows the ease of the regeneration process, and the performance was verified for multiple cycles. In order to understand the structure-function relationship at the atomistic level, grand canonical Monte Carlo (GCMC) calculation was performed, indicating that the primary binding site for CO 2 is between the sulfone moieties in IITKGP-12 . CO 2 is attracted to the bonded structure (V-shape) of the sulfone moieties in a perpendicular fashion, where C CO 2 is aligned with S, and the CO 2 axis bisects the SO 2 axis. Thus, the strategic approach to immobilize the polar sulfone moiety with a high number of inherent stronger M-N coordination and the absence of coordination unsaturation made this MOF potential toward practical CO 2 separation applications.

Over the past decade, the global proliferation of cyanobacterial harmful algal blooms (CyanoHABs) have presented a major risk to the public and wildlife, and ecosystem and economic services provided by inland water resources. As a consequence, water resources, environmental, and healthcare agencies are in need of early information about the development of these blooms to mitigate or minimize their impact. Results from various components of a novel multi-cloud cyber-infrastructure referred to as "CyanoTRACKER" for initial detection and continuous monitoring of spatio-temporal growth of CyanoHABs is highlighted in this study. The novelty of the CyanoTRACKER framework is the collection and integration of combined community reports (social cloud), remote sensing data (sensor cloud) and digital image analytics (computation cloud) to detect and differentiate between regular algal blooms and CyanoHABs. Individual components of CyanoTRACKER include a reporting website, mobile application (App), remotely deployable solar powered automated hyperspectral sensor (CyanoSense), and a cloud-based satellite data processing and integration tool. All components of CyanoTRACKER provided important data related to CyanoHABs assessments for regional and global water bodies. Reports and data received via social cloud including the mobile App, Twitter, Facebook, and CyanoTRACKER website, helped in identifying the geographic locations of CyanoHABs affected water bodies. A significant increase (124.92%) in tweet numbers related to CyanoHABs was observed between 2011 (total relevant tweets = 2925) and 2015 (total relevant tweets = 6579) that reflected an increasing trend of the harmful phenomena across the globe as well as an increased awareness about CyanoHABs among Twitter users. The CyanoHABs affected water bodies extracted via the social cloud were categorized, and smaller water bodies were selected for the deployment of CyanoSense, and satellite data analysis was performed for larger water bodies. CyanoSense was able to differentiate between ordinary algae and CyanoHABs through the use of their characteristic absorption feature at 620 nm. The results and products from this infrastructure can be rapidly disseminated via the CyanoTRACKER website, social media, and direct communication with appropriate management agencies for issuing warnings and alerting lake managers, stakeholders and ordinary citizens to the dangers posed by these environmentally harmful phenomena., (Copyright © 2020 Elsevier B.V.
