Individual interventions, collective lessons: Developing mid-range theory on women's groups to improve health.

Background: Interventions with women's groups have been widely implemented to improve health outcomes in low- and middle-income settings, particularly India. While there is a large evidence base on the effectiveness of single interventions, it is challenging to predict whether a women's group intervention delivered in one setting can be expected to work in another.

Methods: We applied realist principles to develop and refine a mid-range theory on the effectiveness of women's groups interventions, summarised key lessons for implementation, and reflected on the process.

Listening to Patient and Caregiver Voices to Anchor Global Cancer Control.

The experiences of those living with illness and those who care for them are central to disease control and prevention efforts. The history of public health is full of reminders of when consultations with patients and families helped develop meaningful interventions that were ultimately adopted by communities. Global cancer control, on the other hand, seems to increasingly take place in tertiary hospitals and centers where care is sought often at a late stage of cancer.

'We are the bridge': an implementation research study of SEWA Shakti Kendras to improve community engagement in publicly funded health insurance in Gujarat, India.

Introduction: India's efforts towards universal health coverage include a national health insurance scheme that aims to protect the most vulnerable from catastrophic health expenditure. However, emerging evidence on publicly funded health insurance, as well as experience from community-based schemes, indicates that women face specific barriers to access and utilisation. Community engagement interventions have been shown to improve equitable utilisation of public health services, but there is limited research specific to health insurance.

An update on polyethylene and biodegradable plastic mulch films and their impact on the environment.

Many ways are being developed in the realm of agriculture to increase crop yield while inflicting minimal damage to the soil and environment. One among them is the application of agricultural, biodegradable mulch (BDM) films. Organic substances or synthetic materials are used for making mulches.

Toughening Poly(l-lactide) Blends: Effectiveness of Sequence-Controlled Six-Arm Star-Branched Block Copolymers of Poly(l-lactide) and Poly(ε-caprolactone).

Well-defined six-arm star-branched bio-degradable block copolymers of l-lactide and ε-caprolactone were prepared using controlled ring-opening polymerization and a sequential monomer addition method using dipentaerythritol as the initiator core and organocatalysts at low temperatures in solution. Sequence of enchainment was changed by reversing the order of monomer addition giving, either, a crystalline PLA block or an amorphous PCL block as the outer segment. Well-defined six-arm poly(ε-caprolactone--l-lactide, 6s-PCL--PLA) block copolymers were obtained with a range of segment molecular weights.

In-situ interfacial compatibilization via edge-sulfurated few layer graphene during the formation of crosslinked graphene-rubber nanocomposites.

Herein, we report various physico-chemical approaches to probe the nature of the interface between few layers graphene (FLG) and carboxylated nitrile rubber (XNBR) nanocomposites prepared through efficient blending of XNBR latex with an aqueous dispersion of FLG. The extent of physical interaction between FLG and XNBR was investigated using Lorentz-Park and Cunneen-Russell models. The chemical interface between FLG and sulfur crosslinked XNBR was studied using model reactions between sulfur and graphene in presence of zinc 2-mercaptobenzothiazole (ZMBT).

Objectives: The aim of this study was to characterize clinical and neuropsychological profiles and to identify the probable neural substrate for this phenomenon in major cognitive disorder.

Materials And Methods: We conducted a prospective study from February 2015 to May 2017 in patients with Major Cognitive Disorder (MCD, DSM-5 criteria).

Building Capacity for Global Cancer Research: Existing Opportunities and Future Directions.

Cancer incidence and mortality are increasing in low- and middle-income countries (LMICs), where more than 75% of global cancer burden will occur by the year 2040. The primary drivers of cancer morbidity and mortality in LMICs are environmental and behavioral risk factors, inadequate prevention and early detection services, presence of comorbidities, and poor access to treatment and palliation. These same drivers also contribute to marked cancer health disparities in high-income countries.

Understanding the role of female sterilisation in Indian family planning through qualitative analysis: perspectives from above and below.

Since the 1990s, the global approach to family planning has undergone fundamental transformations from population control to addressing reproductive health and rights. The Indian family planning programme has also transitioned from being vertical, target-oriented, and clinic-based to a supposedly target-free, choice-based programme that champions reproductive rights. Despite contraceptive choices being offered and voluntary adoption encouraged, there is a heavy reliance on female sterilisation.

Follow-Up Care for Breast and Colorectal Cancer Across the Globe: Survey Findings From 27 Countries.

Purpose: The purpose of this study was to describe follow-up care for breast and colorectal cancer survivors in countries with varying levels of resources and highlight challenges regarding posttreatment survivorship care.

Methods: We surveyed one key stakeholder from each of 27 countries with expertise in survivorship care on questions including the components/structure of follow-up care, delivery of treatment summaries and survivorship care plans, and involvement of primary care in survivorship. Descriptive analyses were performed to characterize results across countries and variations between the WHO income categories (low, middle, high).

Twist Angle-Dependent Atomic Reconstruction and Moiré Patterns in Transition Metal Dichalcogenide Heterostructures.

Van der Waals layered materials, such as transition metal dichalcogenides (TMDs), are an exciting class of materials with weak interlayer bonding, which enables one to create so-called van der Waals heterostructures (vdWH). One promising attribute of vdWH is the ability to rotate the layers at arbitrary azimuthal angles relative to one another. Recent work has shown that control of the twist angle between layers can have a dramatic effect on TMD vdWH properties, but the twist angle has been treated solely through the use of rigid-lattice moiré patterns.

Synthesis of High-Quality Monolayer MoS by Direct Liquid Injection.

We report the synthesis of high-quality single monolayer MoS samples using a novel technique that utilizes direct liquid injection (DLI) for the delivery of precursors. The DLI system vaporizes a liquid consisting of a selected precursor dissolved in a solvent into small, micron-sized droplets in an expansion chamber maintained at a selected temperature and pressure, before delivery to the deposition chamber. We demonstrate the synthesis of monolayer MoS on SiO/Si substrates using the DLI technique with film quality superior to exfoliated samples or those grown by traditional tube furnace chemical vapor deposition (CVD) methods.

Chemical Identification of Interlayer Contaminants within van der Waals Heterostructures.

van der Waals heterostructures (vdWHs) leverage the characteristics of two-dimensional (2D) material building blocks to create a myriad of structures with unique and desirable properties. Several commonly employed fabrication strategies rely on polymeric stamps to assemble layers of 2D materials into vertical stacks. However, the properties of such heterostructures frequently are degraded by contaminants, typically of unknown composition, trapped between the constituent layers.

Thyrotoxicosis presenting as syncope and rapid wide QRS tachycardia: A case report.

We report regarding a young lady who presented with recurrent syncopal episodes associated with palpitations, documented to be due to rapid wide QRS tachycardia, subsequently detected to have thyrotoxicosis and who responded promptly to appropriate medication to become free from arrhythmia.

Spatially Selective Enhancement of Photoluminescence in MoS by Exciton-Mediated Adsorption and Defect Passivation.

Monolayers of transition-metal dichalcogenides (TMDs) are promising components for flexible optoelectronic devices because of their direct band gap and atomically thin nature. The photoluminescence (PL) from these materials is often strongly suppressed by nonradiative recombination mediated by midgap defect states. Here, we demonstrate up to a 200-fold increase in PL intensity from monolayer MoS synthesized by chemical vapor deposition (CVD) by controlled exposure to laser light in the ambient.

Poly(glycerol sebacate)-Based Polyester-Polyether Copolymers and Their Semi-Interpenetrated Networks with Thermoplastic Poly(ester-ether) Elastomers: Preparation and Properties.

Poly(glycerol sebacate) (PGS), produced from renewable monomers such as sebacic acid and glycerol, has been explored extensively for various biomedical applications. However, relatively less attention has been paid to explore PGS as sustainable materials in applications such as elastomers and rigid plastics, primarily because of serious deficiencies in physical properties of PGS. Here, we present two new approaches for enhancing the properties of PGS; (i) synthesizing block copolymers of PGS with poly(tetramethylene oxide)glycol (PTMO) and (ii) preparing a blend of PGS--PTMO with a poly(ester-ether) thermoplastic elastomer.

Quantum Calligraphy: Writing Single-Photon Emitters in a Two-Dimensional Materials Platform.

We present a paradigm for encoding strain into two-dimensional materials (2DMs) to create and deterministically place single-photon emitters (SPEs) in arbitrary locations with nanometer-scale precision. Our material platform consists of a 2DM placed on top of a deformable polymer film. Upon application of sufficient mechanical stress using an atomic force microscope tip, the 2DM/polymer composite deforms, resulting in formation of highly localized strain fields with excellent control and repeatability.

Double Indirect Interlayer Exciton in a MoSe/WSe van der Waals Heterostructure.

An emerging class of semiconductor heterostructures involves stacking discrete monolayers such as transition metal dichalcogenides (TMDs) to form van der Waals heterostructures. In these structures, it is possible to create interlayer excitons (ILEs), spatially indirect, bound electron-hole pairs with the electron in one TMD layer and the hole in an adjacent layer. We are able to clearly resolve two distinct emission peaks separated by 24 meV from an ILE in a MoSe/WSe heterostructure fabricated using state-of-the-art preparation techniques.
