AI Article Synopsis

  • The study investigates how neutrophil-to-lymphocyte ratio (NLR), serum calcium, and serum albumin predict outcomes for diabetic foot patients.
  • A total of 156 patients were classified into four outcome groups: healing, minor amputation, major amputation, and death, and their lab values were compared.
  • Results indicated that higher NLR correlates with poorer prognosis, while lower levels of serum calcium and albumin also signify worse outcomes for diabetic foot patients.

Article Abstract

The purpose of this study is to investigate the predictive value of neutrophil-to-lymphocyte ratio (NLR), serum calcium, and serum albumin on the prognosis of patients with diabetic foot. A total of 156 patients who were treated in the Department of Burn and Plastic Surgery of Qilu Hospital of Shandong University from 1 January 2014 to 1 August 2020 were selected. All the patients were randomly divided into a healing group, minor amputation group, major amputation group, and death group according to their treatment outcomes. The levels of NLR, serum calcium and serum albumin in each group were examined and compared. The correlations between NLR, serum calcium, and serum albumin with the prognosis of diabetic foot were analysed to investigate their predictive effects on the prognosis of diabetic foot. The results of one-way ANOVA showed that among the 4 groups of patients, the difference in NLR values between the healing group and the minor amputation group was slightly smaller, but they were significantly different from the major amputation group and the death group, respectively. There was no significant difference in serum calcium levels between the healing group and the minor amputation group, but the serum calcium levels of the major amputation group and the death group gradually decreased. The levels of NLR in the 4 groups gradually increased, while the albumin levels gradually decreased. Spearman's rank correlation test indicated that NLR was significantly related to the prognosis of patients with diabetic foot. The group with higher NLR had a worse prognosis in diabetic foot patients. Serum calcium and serum albumin were strongly correlated with the prognosis of patients with diabetic foot. The group with lower serum calcium and serum albumin values had a worse prognosis in diabetic foot patients. The areas under the receiver operator characteristic curve of NLR, serum calcium and serum albumin were 0.901, 0.803, and 0.816, respectively. NLR, serum calcium and serum albumin can be used as reliable indicators to predict the prognosis of diabetic foot. Preoperative diabetic foot patients with higher NLR values or lower serum calcium and serum albumin have a poorer prognosis.

Objective: Ca overload of muscle fibers is one of the factors that secondarily aggravate the development of Duchenne muscular dystrophy (DMD). The purpose of this study is to evaluate the effects of the Ca channel modulator 2-aminoethoxydiphenyl borate (APB) on skeletal muscle pathology in dystrophin-deficient mice.

Methods: Mice were randomly divided into six groups: wild type (WT), WT+3 mg/kg APB, WT+10 mg/kg APB, , +3 mg/kg APB, +10 mg/kg APB.

Purpose: There is paucity of guidelines with inadequate data available about the extent and prevention of bone and joint disease in beta-thalassemic patients in Indian population. This study aims to determine bone and joint involvement in beta-thalassemic patients. It evaluates serum biochemical parameters of bone formation and resorption and correlates with the symptomatology in these patients.

Patients with type 2 diabetes mellitus (T2DM) have increased hip fracture risk. And the association between urine albumin to creatinine ratio (ACR) and an increased risk of hip fracture in patients with T2DM remains controversial. This study aimed to investigate the association between urinary ACR and hip fracture risk in postmenopausal women and aged men with T2DM.

Background: Lambert-Eaton myasthenic syndrome (LEMS) is an autoimmune disorder of the presynaptic neuromuscular junction associated with antibody mediated dysfunction of voltage-gated calcium channels (VGCCs). LEMS can exist as a paraneoplastic syndrome, paraneoplastic-LEMS (P-LEMS), when associated with tumors, most commonly, small cell lung carcinoma (SCLC) or as a non-paraneoplastic condition (NP-LEMS) when no malignancies are detected.

Methods: A retrospective chart review was conducted in 3 tertiary hospitals in Saudi Arabia for patients diagnosed with LEMS between January 2010 and January 2020.

Vitamin D, immune function, and atherosclerosis. Where are we now?

The role of vitamin D in regulating calcium metabolism and skeletal growth and disease is widely recognized. Indeed, current recommendations for serum vitamin D concentrations are based on these parameters. A serum vitamin D <20 ng/mL is considered deficient, concentrations between 20 and 30 ng/mL are insufficient, and >30 ng/mL is adequate.
