Background: Sarcoidosis is a systemic granulomatous inflammatory disease that is associated with inflammatory eye manifestations such as uveitis, cystoid macular edema, and retinal vasculitis. Although Corticosteroids (CS) have traditionally been the mainstay of treatment, there is a clinical need and growing interest in exploring alternative therapeutic options for patients who are refractory to or intolerant of CS or require long-term steroid-sparing agents. Purpose: This case series aims to describe the effectiveness of adalimumab, an anti-tumor necrosis factor (TNF)-α monoclonal antibody, in the management of complex sarcoidosis-related inflammatory eye disease via reduction in CS dosage and ocular exam findings before and after initiation of adalimumab therapy.Method: A retrospective chart review of patients between 2010 and 2023 seen at our academic center’s rheumatology and eye clinics was conducted, with 5 patients meeting the inclusion criteria. Results: Most patients were able to lower, discontinue, or remain off oral CS, while all 5 patients demonstrated a reduction in uveitis activity, Cystoid Macular Edema (CME), and/or retinal vasculitis. Conclusion: These findings suggest a potential role for adalimumab as an effective and safe therapeutic option in the management of complex sarcoidosis-related inflammatory eye disease.

Fine Dust (FD) in the respiratory air generates a variety of human disease issues throughout the earth. This study aimed to investigate whether (1) Tussilago farfara extracts (TF) decrease neutrophils accumulation, typical pathological features, and goblet cell hyperplasia in mice following exposure to fine dust (FD); (2) inflammatory cytokines result from FD exposure; and (3) asymmetric dimethyl-arginine (ADMA) and symmetric dimethyl-arginine (SDMA) levels in the mice following exposure to FD. Seven-week-old male Balb/c mice (n = 5/group) were instilled two times by intra-nasal-trachea (INT) injection for 3 days and 6 days to the mice four groups; normal, control, FD + dexamethasone (Dexa, positive control), and FD + TF groups. TF suspended in 0.5% carboxymethyl cellulose (CMC) was administered orally to the mice daily for 10 days (100 mg/kg). Neutrophil accumulation, typical pathological features, goblet cell hyperplasia, ADMA, and SDMA levels were assessed on day 10 in FD-induced mice. Results indicated FD significantly reduced neutrophil accumulation in BALF, typical pathological features containing goblet cell hyperplasia in lung tissues, and inflammatory cytokines [interleukin (IL)-17 and tumor necrosis factor-α (TNF-α), macrophage inflammatory protein-2 (MIP-2) and C-X-C motif chemokine 1 (CXCL-1)]. Furthermore, TF significantly decreased levels of elevated ADMA and SDMA by FD exposure. Collectively, TF decreased the counts of neutrophils in BALF, histological changes in lung tissues due to downstream secretion of inflammatory cytokines, and levels of ADMA and SDMA. Therefore, TF may be a potential therapeutics for treating FD-associated diseases.

Spin-depending internal magnetic interactions in oxygen are crucial for the chemistry and photobiology of this molecule. Photosynthesis, respiration, and many other life-supporting oxygen reactions are governed by enzymes that use fine magnetic forces to overcome the spin-forbidden character of all aerobic metabolism. Life on Earth occurs on the border between combustion and oxidative phosphorylation, and this balance is largely dependent on reactive oxygen species. ROS can cause apoptosis or cell necrosis, and ROS also controls homeostasis through numerous signaling functions. Until recently, biochemists had not paid attention to internal magnetic interactions that influence the chemical activity of such ROS as superoxide ion, singlet oxygen, peroxynitrite, and many others. The role of superoxide dismutase, the oldest enzyme on the Earth, which provides superoxide concentration control, stresses the importance of the O2-• species as the precursor of many other ROS. Spin-orbit coupling in O2-• and O2 species are the main internal magnetic interactions that could influence cancer growth and be connected with cancer therapy.

Background: Linagliptin is an anti-diabetic drug that claims no adverse effects and treatment of gestational diabetes mellitus (GDM) demands a safe anti-diabetic medication. Therefore, this study investigates the anti-diabetic efficacy of linagliptin in an induced GDM.Materials and methods: Thirty-two matured female rats (100 - 200 g) were utilized. Sixteen non-pregnant/diabetic animals were fed with a normal diet and sixteen rats were fed with a high-fat (HFD), mated at the estrous stage in 2:1, and pregnancy was confirmed with a spermatozoa in a vaginal smear. The pregnant rats were intraperitoneally injected with a single dose (30 mg/kgb. wt)of streptozotocin (STZ) to induce GDM. The animals were grouped into 4 groups, 8 rats/groups. Group I: control; Group II: control + 10 mg/kgb.wt linagliptin; Group III: GDM; Group IV: GDM + 10 mg/kgb.wt linagliptin. The animals were sacrificed after 14 days of treatment. Blood samples were collected for biochemical parameters.Results: Fasting blood glucose (FBG) insulin, glycated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), low-density lipoprotein-cholesterol (LDL-C), malondialdehyde (MDA), interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-alpha (TNF-α) levels significant (p < 0.05) elevated in GDM rats, with significant reduction in high-density lipoprotein-cholesterol (HDL-C), catalase (CAT), superoxide dismutase (SOD) and reduced glutathione (GSH). Linagliptin administration significantly (p < 0.05) decreased the FBG, insulin, HbA1c, TC, TG, LDL-C, MDA, IL-6, IL-1β, and TNF-α and ameliorates the HDL-C, CAT, SOD, and GSH levels significantly.Conclusion: Linagliptin remarkably showed anti-hyperglycemic, anti-oxidative, and anti-inflammatory properties. Linagliptin could be a promising drug for hyperglycemia treatment during gestation.

Introduction: In many developing countries, particularly in Africa, the use of renal biopsy (RB) in clinical nephrology is severely lacking. The objectives were to describe the anatomoclinical and etiological profile of these biopsied nephropathies, as well as the factors associated with the etiology of the nephropathies.Patients and method: This was a retrospective descriptive and analytical study from 1 April 2020 to 30 October 2022. The patients were selected from the renal biopsy register of the nephrology department of the Thiès Regional Hospital. Sociodemographic, clinical, biological, and histological parameters were studied.Results: 75 renal biopsies were included. The mean age was 33.3 ± 14.8 years, with a male predominance (65.3%). The main indications were nephrotic syndrome in 50.67% of cases. RB was adequate in 82.7%, inadequate in 13.3%, and borderline in 4%. Glomerular nephropathies predominated, with focal segmental glomerulosclerosis (FSGS) in 34.7%, membranous nephropathy (MN) in 17.3%, minimal change disease (MCD) in 10.67%, extracapillary glomerulonephritis (ECGN) in 5.3% and lupus nephritis (LN) in 3.9%. Thrombotic microangiopathy (TMA) was found in 9.3%. Chronic tubulointerstitial nephropathy (CTIN) accounted for 5.3% of all RB and acute tubular necrosis (ATN) for 4%. The etiologies were primary in 48%, secondary in 28%, and undetermined in 24%. In the bivariate analysis, the etiology was correlated with the mean SBP (p = 0.023), the mean level of hemoglobin (p = 0.028), the levels of GFR (p = 0.017), and the type of kidney disease (p = 0.000).Conclusion: Glomerular nephropathy was more frequent and FSGS was the most common histological lesion found. Primary causes predominated. Associated factors were identified to improve patient management.

Introduction: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) was first reported in 2003. In 2014, it was revealed that not only bisphosphonates but also other antiresorptive and antiangiogenic drugs can cause osteonecrosis (Medication-related osteonecrosis of the jaw: MRONJ). The aim of this study is to compare awareness and knowledge about BRONJ and MRONJ among specialists/trainers (ST), general dental practitioners (GDP); and dentists who graduated before and after the year 2014. Materials and methods: A survey regarding demographic information and knowledge about BRONJ and MRONJ was prepared and delivered to dentists via social media.Results: A total of 422 dentists participated in our study. It was observed that the awareness and knowledge about BRONJ and MRONJ were statistically higher in ST and in dentists who graduated in 2014 or later. In addition, when their specialties were compared to each other, it was seen that the awareness and knowledge of Oral and Maxillofacial Radiologists (OMR) and Oral and Maxillofacial Surgeons (OMS) were higher than others.Discussion: According to the results of this study, it was seen that the awareness and knowledge of the ST group were higher than GDP, maybe because they may encounter these cases more. In addition, dentists who graduated in 2014 or later had higher awareness, maybe because MRONJ was coined and entered the dentistry education curriculum in 2014. Awareness and knowledge of OMR and OMS were found higher may be because they encounter these patients more frequently. Planning educational strategies for all dentists, especially GDP and dentists who graduated before 2014 is very important for post-graduate dentistry education.

The amniotic membrane, used for over a century, is a widely recognized therapeutic tool in regenerative medicine and reconstructive surgery. Its primary indication is in the treatment of deep partial-thickness burns, where it facilitates epithelialization by providing an optimal environment for tissue regeneration. However, its versatility allows its use in various clinical scenarios, particularly in wounds or trauma where immediate closure is not possible, either due to the patient’s condition or the characteristics of the wound itself. Its most notable benefits include the prevention of necrosis due to desiccation, minimizing the loss of essential proteins, fluids, and electrolytes, reducing the risk of infection by acting as a physical barrier and alleviating pain by covering and stabilizing the wound.Additionally, its ability to act as a temporary biological cover offers a valuable solution in complex cases, improving both the prognosis and the patient’s management.A case series is presented demonstrating various applications of the amniotic membrane.

Background: Sickle cell anaemia (SCA) in children demonstrates a broad range of clinical manifestations and serious complications. Assessment of disease severity in specific populations is necessary to plan services and optimise care. Aim: To describe the clinical severity of SCA and associated sociodemographic and clinical factors in children in Gambia.Methods: The presence of lifetime complications was confirmed by history and review of medical charts. We determined clinical severity using a validated scoring system and related the severity to sociodemographic and clinical factors.Results: In 130 study participants, ages ranged from 5 to 15 years with a mean (SD) age of 9.74 (2.81) years. Eleven (8.5%) children had had acute chest syndrome, 7 (5.4%) avascular necrosis of the femoral head, 6 (4.6%) gallstones, 5 (3.8%) stroke and 1 (0.8%) priapism over their lifetime. Disease severity was classified as mild in 108 (83.1%) children, moderate in 17 (13.1%) and severe in 5 (3.8%). Age, age at diagnosis, sex, ethnicity, social class, and treatment with hydroxyurea was not significantly correlated with SCA clinical severity (P values 0.10-0.84).Conclusion: The high proportion of children with mild disease may be due to the high prevalence of Senegalese β-haemoglobin haplotype in the Senegambia subregion. However, the presence of moderate or severe disease in almost 1 in 5 children calls for concerted efforts in SCD care in this region.
