Hematological parameters in newly diagnosed TB patients: A systematic review and meta-analysis.

Despite all efforts, tuberculosis (TB) remains one of the 10 leading causes of death worldwide. The hematopoietic system is seriously affected by TB and there is little information about the hematological profile of patients with TB. In this regard, this systematic review and meta-analysis aimed to assess hematological parameters among newly diagnosed TB patients. Relevant papers were found by searching in the PubMed database until April 2023. Fifteen papers involving 3354 patients were included. One-sample meta-analysis revealed the low pooled mean values for Hgb of 11.679 g/dl (95 % CI: 10.982-12.377) and the increased pooled ESR of 63.569 mm/h (95 % CI: 57.834-69.304) among newly diagnosed TB patients. The pooled prevalence of anemia, leukocytosis, thrombocytosis, and lymphopenia was 61.6 % (95 % CI: 45.4-75.6 %), 45.9 % (95 % CI: 39.1-52.9 %), 31.9 % (95%CI: 15-55.3 %) and 23.1 % (95%CI: 5.4-61.5 %) between TB patients, respectively. From a two-sample meta-analysis, the RBC and HgB values for TB patients were significantly lower than that of healthy controls (p < 0.05). Awareness of common blood abnormalities like elevated ESR, leukocytosis, and anemia in newly diagnosed TB patients helps physicians in early diagnosis and better management of disease.

Polyphenols and neurodegenerative diseases: focus on neuronal regeneration.

Neurodegenerative diseases are questions that modern therapeutics can still not answer. Great milestones have been achieved regarding liver, heart, skin, kidney and other types of organ transplantations but the greatest drawback is the adequate supply of these organs. Furthermore, there are still a few options available in the treatment of neurodegenerative diseases. With great advances in medical science, many health problems faced by humans have been solved, and their quality of life is improving. Moreover, diseases that were incurable in the past have now been fully cured. Still, the area of regenerative medicine, especially concerning neuronal regeneration, is in its infancy. Presently allopathic drugs, surgical procedures, organ transplantation, stem cell therapy forms the core of regenerative therapy. However, many times, the currently used therapies cannot completely cure damaged organs and neurodegenerative diseases. The current review focuses on the concepts of regeneration, hurdles faced in the path of regenerative therapy, neurodegenerative diseases and the idea of using peptides, cytokines, tissue engineering, genetic engineering, advanced stem cell therapy, and polyphenolic phytochemicals to cure damaged tissues and neurodegenerative diseases.

Improvement of sleep quality 6 months after total knee arthroplasty: a systematic review and meta-analysis.

BACKGROUND: Total knee arthroplasty (TKA) is an accepted, effective treatment to restore function, relieve pain, and improve the quality of life in patients with advanced osteoarthritis. One complication of this major surgery is impaired sleep quality. This study examines the quality of sleep in patients undergoing TKA before and after their operation. METHODS: All relevant records were obtained using a systematic search in three online databases: PubMed, Scopus, and Cochrane library. Out of the 177 records retrieved, only eight matched the inclusion criteria. Due to the lack of sufficient data, only four studies entered the meta-analysis. Values reported for sleep quality based on the Pittsburgh Sleep Quality Index (PSQI) were extracted from patient records before and after surgery. A random-effect model was used to analyze the data. RESULTS: The results of the meta-analysis show a significant difference in the improvement of sleep quality after surgery at two time points of 4-6 weeks after surgery from the preoperative baseline (SMD - 0.16; 95% CI - 1.05 to 0.74; P = 0.0) and 3-6 months after surgery from the preoperative baseline (SMD - 0.92; 95% CI - 1.61 to - 0.24; P = 0.0). CONCLUSIONS: The results show that TKA generally improves the patients' sleep quality. Although some studies reported disrupted sleep quality in periods close to the surgery (especially in the early days after surgery), all studies have reported improved sleep quality in the late postoperative intervals.
