Serum Albumin as Prognostic Marker for Older Adults in Hospital and Community Settings.

Serum albumin, known for its multifaceted role in health, is hypothesized to serve as a prognostic marker for older adults, both in hospital and community settings. Nine studies were included in the review, revealing consistent associations between low serum albumin levels and increased mortality risk in hospitalized older individuals. In community settings, low serum albumin levels were linked to higher mortality rates compared to those with normal levels. The synthesis of evidence underscores the potential of serum albumin as a prognostic marker for older adults, offering valuable insights for risk stratification and targeted interventions. While robust evidence supports its utility in hospital settings, further research is warranted in community settings to address current limitations and enhance the applicability of serum albumin as a prognostic tool. This review merges existing knowledge of the prognostic significance of serum albumin in older adults across hospital and community settings. The findings emphasize the importance of serum albumin as a potential prognostic marker, urging continued research efforts to refine its application in diverse healthcare contexts and improve outcomes for the aging population.

Ophiocephalus striatus Extract Supplementation Decreases Serum IL-6 Levels in Older People with Sarcopenia-A Single-Center Experience.

Sarcopenia, a condition characterized by muscle loss and decreased function in older adults, is a growing public health concern. This study aimed to investigate the effects of Ophiocephalus striatus extract on insulin-like growth factor-1 serum, interleukin-6 serum levels, and sarcopenia-related parameters in older adults with sarcopenia. This double-blind randomized controlled trial included 80 older adults with sarcopenia. Participants were randomly assigned to receive Ophiocephalus striatus extract or a placebo for two weeks. The IGF-1 serum and IL-6 serum levels were assessed as primary outcomes. The Ophiocephalus striatus extract intervention resulted in a significant reduction in serum IL-6 levels. Although the IGF-1 levels did not show significant changes, there was an increase for the intervention group. This study demonstrated that a 2-week intervention with Ophiocephalus striatus extract positively impacted the serum IL-6 levels in older adults with sarcopenia. While the IGF-1 levels did not change significantly in this short intervention period, the observed improvements in IGF-1, calf circumference, muscle mass, and muscle strength are promising. The findings suggest that Ophiocephalus striatus extract may offer a valuable intervention for managing sarcopenia, particularly in regions with abundant Ophiocephalus striatus production, such as South Sumatera. This study was registered with trial number NCT05869383.

Treponema Pallidum rapid syphilis compared diagnostic algorithm syphilis in men who have sex with men (MSM).

BACKGROUND: Syphilis infection can be asymptomatic and difficult to diagnose based on clinical symptoms. Early detection and treatment are critical for preventing and controlling syphilis as well as long-term serious complications. A serological examination based on the diagnostic algorithm was used to confirm the diagnosis of syphilis. Syphilis is frequent in high-risk groups, such as men who have sex with men (MSM). Treponema pallidum (TP) rapid can be used for early syphilis detection. The diagnostic value of TP rapid with diagnostic algorithm (RPR-TPHA) utilizing whole blood in MSM should be studied. OBJECTIVES: To determine the diagnostic value of TP rapid syphilis test compared to a diagnostic algorithm (RPR-TPHA) among MSM. METHODS: A diagnostic test with a cross-sectional design at Dr Mohammad Hoesin Palembang General Hospital from November 2022 to January 2023. The sampling method was consecutive sampling with a total sample of 83 MSM based on inclusion and exclusion criteria. All samples were tested for RPR, TPHA, and TP rapid. The diagnostic value of TP rapid was evaluated with RPR-TPHA as a diagnostic algorithm for syphilis. RESULTS: The sensitivity and specificity value of the TP rapid compare diagnostic algorithm as gold standard were 95.8% and 96.6% respectively. Other metrics: positive predictive value (PPV) 92%, negative predictive value (NPV) 98%, positive likelihood ratio (PLR) 28.27, negative likelihood ratio (NLR) 0.04, accuracy 96% and AUC 0.962. CONCLUSION: The TP rapid test has a high diagnostic value and can be used to establish an early diagnosis of syphilis in MSM.

A systematic review: is Anopheles vagus a species complex?

BACKGROUND: Anopheles vagus (subgenus Cellia) has been identified as a vector for malaria, filariasis, and Japanese encephalitis in Asia. Sporozoites of Plasmodium falciparum and Plasmodium vivax have been found in this zoophilic mosquito in Asia and Indonesia. This study systematically reviews publications regarding An. vagus species, variation, bio-ecology, and malaria transmission in various localities in Asia, especially Indonesia, to determine whether the current data support An. vagus as a species complex. METHODS: The databases Pubmed, Scopus, Europe PMC, and Proquest were searched to identify information regarding the morphology, karyotypes, polytene chromosome, cross-mating, ecology, and molecular identification of An. vagus was then evaluated to determine whether there were possible species complexes. RESULTS: Of the 1326 articles identified, 15 studies were considered for synthesis. The Anopheles spp. samples for this study came from Asia. Eleven studies used morphology to identify An. vagus, with singular studies using each of karyotype identification, chromosomal polytene identification, and cross-breeding experiments. Ten studies used molecular techniques to identify Anopheles spp., including An. vagus. Most studies discovered morphological variations of An. vagus either in the same or different areas and ecological settings. In this review, the members of An. vagus sensu lato grouped based on morphology (An. vagus, An. vagus vagus, An. vagus limosus, and An. limosus), karyotyping (form A and B), and molecular (An. vagus genotype A and B, An. vagus AN4 and AN5). Genetic analysis revealed a high conservation of the ITS2 fragment among members except for the An. vagus genotype B, which was, in fact, Anopheles sundaicus. This review also identified that An. vagus limosus and An. vagus vagus were nearly identical to the ITS2 sequence. CONCLUSION: Literature review studies revealed that An. vagus is conspecific despite the distinct morphological characteristic of An. vagus and An. limosus. Further information using another barcoding tool, such as mitochondrial COI and ND6 and experimental cross-mating between the An. vagus and An. limosus may provide additional evidence for the status of An. vagus as a species complex.

Inhibition of Receptor for Advanced Glycation End Products as New Promising Strategy Treatment in Diabetic Retinopathy.

BACKGROUND: Extensive intracellular and extracellular formation of advanced glycation end-products (AGEs) is considered a causative factor for vascular injury triggered by hyperglycemia in diabetes. The hyperglycemia will cause accumulation of AGEs, damage to pericytes, nerve growth factor (NGF), glial acid fibrillary protein (GFAP) and increase in vascular endothelial growth factor (VEGF). AIM: This study aimed to assess the efficacy of RAGE inhibition in suppressing the development and progression of diabetic retinopathy through modulation of the inflammatory pathway involving NGF, GFAP, and VEGF. METHODS: The design was in vivo experimental study. Thirty white rats were induced with Alloxan monohydrate. Rats were divided into 5 groups, normal, negative control, groups with an anti-RAGE dose of 1 µg/uL, the dose of 10 µg/uL and 100 µg/uL. After 4 weeks of treatment, HbA1c, NGF, and GFAP levels were measured using ELISA. Quantification of VEGF expression was done using the ImageJ® application. Data was expressed with mean ± SD. Independent T-test with ANOVA and Tukey's post hoc was done. RESULTS: RAGE inhibitors yielded a significant decrease in blood glucose and HbA1c levels. VEGF and RAGE expression were reduced in anti-RAGE groups in various doses. Inhibition of RAGE reduced the damage of retinal pericytes, by reducing GFAP and increasing NGF, and reduced the formation of new blood vessels, by decreasing VEGF expression, in diabetic retinopathy. CONCLUSION: Inhibition of receptor for advanced glycation end-products (RAGE) was effective in suppressing the development and progression of diabetic retinopathy.

Association between A1166C Polymorphism of the Angiotensin II Type-1 Receptor Gene and Type-2 Diabetic Nephropathy in an Indonesian Malay Population.

BACKGROUND: diabetic nephropathy (DN) is the leading cause of blood dialysis worldwide and a major etiology of End-Stage Renal Disease cases in Indonesia. Previous studies showed a relevant link between A1166C polymorphism of Angiotensin II Type-1 Receptor (AT1R) gene and glomerular hyper-filtration as a part of pathogenesis of DN. The aim of this study was to elaborate the association between A1166C AT1R polymorphism and susceptibility of individual with type-2 diabetes to DN in Malay Indonesian population. METHODS: a case-control study of 120 consecutive patients with type-2 diabetes mellitus (40 patients in each groups for macro-albuminuria, micro-albuminuria, and normo-albuminuria) was conducted for A1166C AT1R gene polymorphism. The A1166C polymorphism of the AT1R gene was determined based on PCR/RFLP. RESULTS: the mutant C allele was found in 5%, 13.75%, and 12.5% in normo-, micro-, and macro-albuminuria patients respectively. The heterozygote AC genotype was found significantly higher in micro-albuminuria, compared to normo-albuminuria group. Heterozygote AC genotype (OR 3.2 [1.01-10.08], p=0.03) and C allele (OR 2.8[0.95-8.67], p=0.038) were significantly higher in DN, indicating A1166C AT1R gene polymorphism as a risk factor for DN in Malay Indonesian population with type-2 diabetes. CONCLUSION: there was positive association between A1166C AT1R polymorphism and susceptibility of type-2 diabetics to DN in Malay Indonesian Population. It also indicated that the A1166C AT1R polymorphism could play a role in early pathogenesis of DN.
