ADHERENCE TO NUTRITIONAL SUPPLEMENTATION, FOLLOW-UP CARE, AND LOST TO FOLLOW-UP IN POST BARIATRIC SURGERY PATIENTS.

Background: With the global rise in obesity rates, bariatric surgery has emerged as an effective intervention for weight management and obesity-related comorbidities. Bariatric surgery offers transformative potential but demands lifelong adherence to multifaceted care, including nutritional supplementation and vigilant follow-up. Nutritional deficiencies affect 30% to 70% of patients, encompassing vital elements like vitamins (B12, D, folate), minerals (iron, zinc, calcium), and proteins, necessitating continuous monitoring to prevent complications.

The Role of Alpha-Synuclein and Tubulin-Associated Unit (Tau) Proteins in the Diagnosis, Prognosis, and Treatment of Parkinson's Disease: A Systematic Review.

Parkinson's disease (PD) is a degenerative neurological disorder resulting from the death of dopaminergic neurons, which, in turn, results in impaired motor and cognitive functions. Early diagnosis is important in achieving a good prognosis for PD. Currently, the only approved way to diagnose PD is through medical history, current symptoms, and neurological examination.

The Role of Oral Probiotics in Alleviating Inflammation, Symptom Relief, and Postoperative Recurrence and Their Side Effects in Adults With Crohn's Disease: A Systematic Review.

Crohn's disease (CD) is a lifelong problem for patients, despite having multiple pharmacological options and surgeries for treatment. In order to achieve best results, probiotics are being used even though their efficacy is still debatable. This systematic review analyzes the safety and efficacy of several probiotics in CD.

Co-delivery of azithromycin and ibuprofen by ROS-responsive polymer nanoparticles synergistically attenuates the acute lung injury.

Bacterial infection causes lung inflammation and recruitment of several inflammatory factors that may result in acute lung injury (ALI). During bacterial infection, reactive oxygen species (ROS) and other signaling pathways are activated, which intensify inflammation and increase ALI-related mortality and morbidity. To improve the ALI therapy outcome, it is imperative clinically to manage bacterial infection and excessive inflammation simultaneously.

Acceptability and feasibility of intra-peer and social media approach for HIV self-testing among men who have sex with men in Karachi: lessons from a pilot study.

Objective: To use a peer-to-peer and social media approach to reach out to men who have sex with men (MSM) and to distribute human immunodeficiency virus self-testing kits among them in an urban setting.

Methods: The cross-sectional, pilot study was conducted by a community-based organisation in Karachi from November 2020 to February 2021, and comprised men aged 18 years or above who have sex with men. The subjects were provided one human immunodeficiency virus self-testing kit (HIVST) per person by trained outreach workers.

ROS-responsive polymer nanoparticles with enhanced loading of dexamethasone effectively modulate the lung injury microenvironment.

The acute lung injury (ALI) is an inflammatory disorder associated with cytokine storm, which activates various reactive oxygen species (ROS) signaling pathways and causes severe complications in patients as currently seen in coronavirus disease 2019 (COVID-19). There is an urgent need for medication of the inflammatory lung environment and effective delivery of drugs to lung to reduce the burden of high doses of medications and attenuate inflammatory cells and pathways. Herein, we prepared dexamethasone-loaded ROS-responsive polymer nanoparticles (PFTU@DEX NPs) by a modified emulsion approach, which achieved high loading content of DEX (11.

Biomedical polymers: synthesis, properties, and applications.

Biomedical polymers have been extensively developed for promising applications in a lot of biomedical fields, such as therapeutic medicine delivery, disease detection and diagnosis, biosensing, regenerative medicine, and disease treatment. In this review, we summarize the most recent advances in the synthesis and application of biomedical polymers, and discuss the comprehensive understanding of their property-function relationship for corresponding biomedical applications. In particular, a few burgeoning bioactive polymers, such as peptide/biomembrane/microorganism/cell-based biomedical polymers, are also introduced and highlighted as the emerging biomaterials for cancer precision therapy.

Macrophage membrane-functionalized nanofibrous mats and their immunomodulatory effects on macrophage polarization.

Immunomodulation is an important phenomenon in the normal mammalian host response toward an injury, and plays a critical role in tissue regeneration and regenerative medicine. Different phenotypes of macrophages show an array of activation states compassing pro-inflammatory to pro-alleviating cells, which are the critical players to modulate immune response and tissue regeneration. In this study, macrophage membranes of different phenotypes (macrophages (M0), classically activated macrophages (M1) and alternatively activated macrophages (M2)) were coated onto poly-ε-caprolactone (PCL) nanofibers to acquire exterior surface proteins and similar functions of the natural membranes.

Inflammation-modulating nanoparticles for pneumonia therapy.

Pneumonia is a common but serious infectious disease, and is the sixth leading cause for death. The foreign pathogens such as viruses, fungi, and bacteria establish an inflammation response after interaction with lung, leading to the filling of bronchioles and alveoli with fluids. Although the pharmacotherapies have shown their great effectiveness to combat pathogens, advanced methods are under developing to treat complicated cases such as virus-infection and lung inflammation or acute lung injury (ALI).

Blood pressure variability in normotensive perimenopausal women: Non-dipping status, maximum blood pressure and arterial stiffness.

Background: Postmenopausal women are more likely to have uncontrolled hypertension and are at higher risk of cardiovascular disease compared with age-matched men. Blood pressure variability is emerging as a predictor of adverse cardiovascular outcomes and may be implicated in the relationship between menopause and worsened vascular health in women. We conducted an observational study, BRAVE (Blood pRessure And Vascular hEalth around menopause) to study this relationship.

Antiviral Activity of Nanomaterials against Coronaviruses.

One of the challenges facing by world nowadays is the generation of new pathogens that cause public health issues. Coronavirus (CoV) is one of the severe pathogens that possess the RNA (ribonucleic acid) envelop, and extensively infect humans, birds, and other mammals. The novel strain "SARS-CoV-2" (severe acute respiratory syndrome coronavirus-2) causes deadly infection all over the world and presents a pandemic situation nowadays.

Micro- and nanoparticles-based immunoregulation of macrophages for tissue repair and regeneration.

The importance of inflammatory tissue microenvironment on the repair and regeneration of tissues and organs has been well recognized. In particular, the phenotypes of macrophages can significantly influence on the processes of tissue repair and remodeling. Among the many types of biomaterials, the particles in the range from nanometers to submicron meters have been extensively studied and applied in tissue engineering and regenerative medicine.

Optical, morphological and biological analysis of zinc oxide nanoparticles (ZnO NPs) using L.

Biogenic synthesis using medicinal plants has less harmful effects as compared to chemically synthesized nanoparticles.
