Diabetic Nephropathy is one of the major microvascular complications of Diabetes Mellitus, which can be detected in the earlier stage by investigating urinary microalbumin excretion levels and estimating ACR and GFR. Early treatment can delay or prevent the progression of diabetic Nephropathy. Monoherbal Siddha formulation Sirupeelai Kudineer indicated for the complications of Diabetes Mellitus is selected for this Case study.

Health system resilience refers to the capacity of a health system to effectively anticipate, assimilate, adjust to and recuperate from unforeseen disruptions and pressures. Evidence indicates that low- and middle-income countries (LMICs) have a double burden of dealing with the existing shortage of health resources in managing both non-emergency care and emergency care during epidemics. Intersectoral collaboration plays a pivotal role in managing crises such as pandemics.

Article Synopsis
  • This study aimed to assess the rates of retinopathy of prematurity (ROP) and its treatment, along with identifying systemic risk factors in extremely preterm or low-birth-weight infants in a tier-2 city in Kerala, India.
  • Analysis included 54 babies with an average gestational age of 27.5 weeks and birth weight of 847 g; ROP was detected in 87%, with 19.1% requiring treatment, which was mostly managed through laser or injection therapies.
  • Findings indicate that the incidence and outcomes of ROP and treatment align with global statistics, highlighting improvements in neonatal care, while conditions like inotropic support and anemia could increase ROP risk and

Ultra-small nanoparticles, including quantum dots, gold nanoclusters (AuNCs) and carbon dots (CDs), have emerged as a promising class of fluorescent material because of their molecular-like properties and widespread applications in sensing and imaging. However, the fluorescence properties of ultra-small gold nanoparticles (, AuNCs) and CDs are more complicated and well distinguished from conventional quantum dots or organic dye molecules. At this frontier, we highlight recent developments in the fundamental understanding of the fluorescence emission mechanism of these ultra-small nanoparticles.

Background: Multimorbidity or multiple long-term conditions (MLTCs), the coexistence of two or more chronic conditions within an individual, presents a growing concern for healthcare systems and individuals' well-being. However, we know little about the experiences of those living with MLTCs in low- and middle-income countries (LMICs) such as India. We explore how people living with MLTCs describe their illness, their engagements with healthcare services, and challenges they face within primary care settings in Kerala, India.

Background: The rise in epidemic-prone diseases daily poses a serious concern globally. Evidence suggests that many of these diseases are of animal origin and contribute to economic loss. Considering the limited time and other resources available for the animal and human health sectors, selecting the most urgent and significant risk factors and diseases is vital, even though all epidemic-prone diseases and associated risk factors should be addressed.

Popliteal artery entrapment syndrome (PAES) is a rare cause of intermittent claudication in the young. Aberrant embryological development results in entrapment of the popliteal artery by myofascial structures of the popliteal fossa. Type 4 PAES is due to aberrant development of the popliteus muscle superficial to the popliteal artery.

Background: 61% of the infections around the world that have emerged to date are zoonotic. Evidence warns that the threat posed by zoonoses is on the rise, and the risk of a new pandemic is higher now than ever. Early identification of risk, populations at risk, and risk of transmission are essential steps towards a prevention, preparation and response to outbreaks.

Background: Globally, the cases of type 2 diabetes are increasing, and this is largely attributed to lifestyle changes. Though diabetes is primarily a metabolic disease determined by biological factors, psychosocial aspects play a crucial role in its progression and management. However, the literature on psychosocial dimensions of diabetes management is minuscule and scattered.

Background: With the increasing proportion of older adults in India, it becomes essential to get an insight into the various influencing factors of successful ageing. However, the literature on successful ageing is minuscule in the Indian context. The present study attempted to understand successful ageing in terms of active and productive ageing by exploring their determining factors.

Background: Pregnancy is an immuno-compromised state, and pregnant women with COVID-19 are at an increased risk for adverse pregnancy outcomes. Thus, the Center for Disease Control and Prevention (CDC) and the Advisory Committee on Immunization (ACIP) have advocated for COVID-19 vaccination in pregnant women. COVAXIN and COVISHIELD were the vaccines being used in India in the first phase of vaccination, but limited data exist on pregnancy outcomes regarding SARS-CoV-2 vaccines and pregnancy and lactation.

Curcumin in 0.5% and 1% doses was given as a feed additive to tilapia (Oreochromis mossambicus) for 100 days to evaluate the effect of curcumin on fatty acid levels in brain, appetite and the growth axis-related gene expressions. A total of 180 fish were randomly stocked into 650 l tanks and fed with basal feed during acclimatization.

This study describes the development of a low-cost fluorescence assay for detecting homocysteine (Hcy) without the interference of cysteine and glutathione using carbon quantum dots. Herein nitrogen-doped carbon quantum dots (NCDs) were synthesized from citric acid as the carbon source and urea as the dopant using a one-pot microwave-assisted method. The obtained NCDs were incorporated with folic acid (FA) by the direct ex situ addition method and were used as a fluorescence probe to detect Hcy.

Background: Among screening instruments used to diagnose dementia by interviewing the caregivers rather than the patients, Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) is widely used.

Objectives: To adapt and validate IQCODE in a Malayalam-speaking population and to study the utility of IQCODE in diagnosing dementia.

Materials And Methods: Cross-sectional study conducted as a two-phase survey on individuals aged ≥55 years availing dementia care services at three tertiary care hospitals and a dementia clinic in Kerala, India.

Thromboembolic complications are being increasingly reported in patients with COVID-19 due to the associated hypercoagulability and are an important cause for morbidity and mortality. Retinal vascular occlusions especially arterial occlusions are one of the gravest ocular complications reported. This complication may occur in severe cases with cytokine storm or even in mild or asymptomatic patients and presentation can be anytime from few days to weeks after the onset of symptoms.

Introduction: Access to patients' documented medical information is necessary for building the informational continuity across different healthcare providers (HCP), particularly for patients with non-communicable diseases (NCD). Patient-held health records (PHR) such as NCD notebooks have important documented medical information, which can contribute to informational continuity in the outpatient settings for patients with diabetes and hypertension in Kerala. We aimed to use the theoretical domains framework (TDF) to identify the perceived HCP factors influencing informational and management continuity for patients with diabetes and hypertension.

Finite element analysis (FEA) is one of the best methods for evaluating the stress distribution of restorations, such as fixed partial dentures. The development of resin cement has transformed prosthesis bonding and retention properties. Resin-bonded fixed partial dentures (RBFPD) have been considered minimally invasive treatment options for the prosthetic rehabilitation of single missing teeth.

Rheumatoid arthritis (RA) is of foremost concern among long-term autoimmune disorders, as it leads to inflammation, exudates, chondral degeneration, and painful joints. Because RA severity often fluctuates over time, a local drug delivery method that titrates release of therapeutics to arthritis bioactivity should represent a promising paradigm of RA therapy. Given the local nature of RA chronic illnesses, polysaccharide-drug delivering systems have the promise to augment therapeutic outcomes by offering controlled release of bioactive materials, diminishing the required frequency of administration, and preserving therapeutic levels in affected pathological regions.
