We wanted to examine the serum profile of hypothalamic-pituitary-testicular-axis (HPTA) hormones and how they relate to sexual function in older men with type-2 diabetes. This study included 74 participants (44 type-2 diabetics and 30 healthy controls). The enzyme-linked immunosorbent assay (ELISA) method was used to measure serum levels of total testosterone (Te), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin (PRL). Compared to controls, diabetic patients had significantly higher FSH and PRL levels but lower Te levels. Testosterone was found to be significantly correlated with sexual intercourse frequency (p<0.01), erectile function, and libido (p< 0.001). We discovered significant (p < 0.001) relationships between libido, penile erection, and FSH, as well as between PRL and libido (p< 0.05). When compared to the other hormones, testosterone had the strongest associations with the frequency of sexual intercourse (p< 0.05), libido (p< 0.05), and penile erection (p< 0.01). Our findings indicated that HPTA hormones might have a significant influence on sexual functions in type-2 diabetic patients, with Te being the most important HPTA hormone influencing sexual functions in diabetic patients. This study, therefore, helps to clarify the complex endocrinology and physiology of the sexual dysfunction frequently observed in older men with type-2 diabetes and also supports the use of testosterone replacement therapy in older diabetic adults.","PeriodicalId":32131,"journal":{"name":"Medical Laboratory Technology Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42507522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shortened PTTK and PT represent a hypercoagulable state related to an elevated thrombotic risk and a negative cardiovascular effect, both of which can lead to the onset and progression of microvascular and macrovascular problems. The study aims to compare the coagulation profile in diabetes-related microvascular complications in clients with uncontrolled and controlled diabetes at an Edo specialty hospital in Benin City. A hospital-based case-control study was carried out at ESH in Benin City. Two hundred eighty individuals were recruited for the study, including 215 diabetes patients (55 type I diabetes, 160 type II diabetes, and 65 non-diabetics) attending the outpatient department of ESH in Benin City. Blood was drawn for coagulation and biochemical assays. Diabetes patients had significantly lower levels of PT and PTTK compared to non-diabetes controls (p<0.05). Fibrinogen and D-dimer levels were considerably higher (p<0.05). The PTTK level was much lower in type 2 diabetes than in type 1 diabetes, and there was a significant difference in platelet count between type 1 and type 2 diabetes. Female diabetes patients had lower levels of PTTK and PT than male diabetic patients. Furthermore, in diabetes with complications, the levels of PTTK and platelet count were lower (p0.05). It was discovered that insulin treatment decreased platelet count, whereas sulfonylurea increased fibrinogen levels in people with diabetes. Diabetes may increase the risk of clotting, as indicated by shorter PTTK, PT, and higher fibrinogen and D-dimer levels compared to controls. The coagulation profile should be evaluated as a regular screening test in diabetes patients to reduce the incidence and prevalence of vascular burden and to improve quality of life.","PeriodicalId":32131,"journal":{"name":"Medical Laboratory Technology Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49339068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most people with diabetes mellitus go through the prediabetes phase. Prediabetes is a condition where blood glucose levels are elevated but have not yet reached the criteria for diabetes mellitus. Low-grade chronic inflammation is one of the pathways known to interfere with insulin signalling that ultimately affects blood glucose levels. One of the most studied inflammatory pathways in the pathogenesis of diabetes mellitus is interleukin-6 (IL-6). This study aims to determine whether there were differences in IL-6 levels between groups of prediabetes subjects and normal subjects and to observe the correlation between IL-6 levels and blood glucose. This study is useful in providing additional scientific evidence on the development of diabetes mellitus, especially in blood glucose regulation through inflammatory pathways. The design of this study was analytic observational in 71 subjects with prediabetes or normal glycemic status. Prediabetes status was established based on fasting blood glucose levels and glucose levels 2 hours post oral glucose tolerance test. Subjects with fasting blood glucose levels> 125mg/ dl and who had a fever in the last week were excluded from the study. Interleukin 6 levels were measured based on the principle of enzyme-linked immunoassay. The correlation of interleukin 6 with glucose levels and other variables was analyzed using the spearmen test. The results showed that interleukin 6 levels did not differ between the prediabetes group and the normal group ((5.27 ± 2.55 pg/ml) vs (4.44 ± 2.46) respectively; (p=0.105)). There was no correlation between interleukin 6 level and fasting blood glucose level (r=0.014, p=0.908) and glucose level after the oral glucose tolerance test (r=-0.085, p=0.480). In this study, there was a significant correlation between body mass index with waist circumference (r=0.772, p=0.000) and glucose levels after the oral glucose tolerance test (r=0.240; p<0.001). Recommends the addition of anti-inflammatory cytokines and variable insulin to assess further the effect of the inflammatory process on the glucose metabolism of subjects in future studies.","PeriodicalId":32131,"journal":{"name":"Medical Laboratory Technology Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48612794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine the correlation between parasitemia and anemia in BABL/c mice infected with Plasmodium berghei ANKA. Two uninfected and infected mice groups were compared for parasitemia, HGB, and HCT levels. Analysis statistics showed a significant difference in HGB and HCT between uninfected and infected groups. Pearson correlation analysis showed no significant correlation between parasitemia and HGB and HCT levels in infected mice. Anemia in mice infected with Plasmodium berghei ANKA can occur when parasitemia is even low; the higher parasitemia worsens the hamatological condition. Parasitemia plays a role independently in the severity of anemia. Plasmodium berghei infection in mice is useful for studying malaria anemia.","PeriodicalId":32131,"journal":{"name":"Medical Laboratory Technology Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45831674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common known side effect of this drug is infertility. Curcumin, also called turmeric, has antioxidant and antitumor activities. This study was designed to investigate the effects of curcumin on the changes in spermatogenetic cells caused by cisplatin, which is used as a chemotherapeutic drug especially in testicular cancers. For this purpose, randomly selected 36 Spraque Dawley rats were seperated to 4 groups that of control, cisplatin, curcumin and curcumin+cisplatin and each group was seperated to 3 subgroups, each of them have 3 rats, so total 12 subgroups were obtained. The testicular tissues obtained from rats were evaluated histochemically, immunohistochemically and ultrastructually. In the results of this study, it is observed that the rate of apoptosis increased significantly in the experimental groups given curcumin together with cisplatin injection, and the transition-1 protein which is involved in DNA packaging in the elongated spermatids belonging to stages of XII, XIII an XIV, immunopositivity is increased statistically in the cisplatin-administered experimental groups compared to control groups. Both light and electron microscopic findings showed that intense degeneration, vacuolization, germ cell loss and spermatogenetic arrest occurred especially in the group given curcumin together with cisplatin. The results of our study showed that cisplatin can cause problems in infertility through DNA packaging and dragging cells to apoptosis and necrosis. Physicians who use cisplatin for cancer treatment are advised not to use curcumin together with cisplatin because it exacerbates the side effects of the cancer drug.","PeriodicalId":32131,"journal":{"name":"Medical Laboratory Technology Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48259620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Haematological parameters play an essential role in SAT; these parameters begin to normalise after the thyrotoxic phase; however, there is still a gap in knowledge about how these parameters play a role in SAT prognosis. Therefore, we wanted to investigate haematological parameters and their impact on treatment response and recovery phase in patients with SAT. 51 SAT patients and 44 healthy controls were included in the study. ESR, CRP, NLR and MPV were recorded at the diagnosis and after resolution. The changes in these parameters were compared to determine the resolution phase. The ratio of permanent hypothyroidism after one year was studied, and its relevance with these parameters at the time of diagnosis was explored. 36 of 51 SAT patients were female in the study (70.5%). The mean age was 45.53 ± 11.46 years. In the acute phase, WBC, Neutrophil, platelet, ESR, N/L, and P/L were significantly higher (p<0.05). In the recovery phase, MPV and lymphocyte count were significantly higher (p: 0.002 and p=0.002). WBC, CRP, and ESR had the highest AUC values in ROC analysis (0.990, 0.959, 0.907, p<0.05). P/L and N/L ratios also had higher ratios for the acute phase (0.807, 0.98, p<0.05, respectively). Δ ESR, Δ CRP, Δ N/L, and Δ P/L had the highest AUC for the recovery phase (AUC= 0.990, 0.899, 0889,0.800, p<0.5, respectively). Permanent hypothyroidism after one year was 9/42 (21.4%). In addition to ESR and CRP, NLR, PLR and MPV were also successfully used to estimate SAT activity and response to treatment.

This cross-sectional study was conducted during June and July 2021. PT was measured in the plasma samples, stored at different temperatures at baseline (0 hours), and then after 12 hours, 18 hours, and 24 hours after specimen collection. INR was calculated from each result, and the deviation percentage of PT and INR was calculated compared to the baseline result (0 hours). Then PT and INR percentage deviation is grouped as <10% and >10% to find biologically significant variations while paired t-test was performed to find statistical significance using GraphPad prism 8.4.3. At refrigerated temperature, both PT and INR results showed>10% variation once kept 24 hours, and this variation was statistically significant (p<0.01, Wilcoxon matched paired sign ranked test). The plasma specimens kept at laboratory temperature and specimen collection room temperature for 18 hours indicated >10% variation of PT and INR values, while these variations were significant at the same criteria above. These results suggest that the separated plasma could only be recommended to test up to 12 hours.
