As part of the process of structural transformation that countries go through in their development journey, the relative significance of agriculture as a sector typically shrinks over time. Nonetheless, the agricultural sector maintains its significance in terms of its trade potential and global employment prospects to this day. The extant literature largely neglects the impact of countries’ land resources on agricultural trade by emphasizing agricultural farm size and land productivity nexus. This justifies the exploration of the causal nexus between countries’ agricultural land resources and their agricultural exports.

- Abstract
Background: Positive T-wave polarity in the augmented vector right lead (Tw-aVR) and ST-segment deviation in the augmented vector right lead (STaVR) have been identified as potential predictors of adverse outcomes in various cardiac conditions., Aim: The aim of the study was to examine the effect of positive Tw-aVR and STaVR on in-hospital mortality after coronary artery bypass grafting (CABG) surgery in patients with heart failure with reduced ejection fraction (HFrEF)., Methods: A five-year retrospective study was conducted on 250 HFrEF patients who underwent CABG at a tertiary care hospital between January 2018 and December 2022. The primary outcome was in-hospital mortality, and the main exposures were positive Tw-aVR and STaVR on preoperative electrocardiograms. Logistic regression models were used to assess the factors associated with in-hospital mortality., Results: Two hundred and fifty patients with a mean age of 67.4 ± 8.1 years were studied. Males constituted 68% of the participants. Among the participants, 60 (24%) had positive Tw-aVR, and 96 (38.4%) had STaVR. The overall in-hospital mortality rate was 7.6%, and patients with positive Tw-aVR and STaVR had significantly higher mortality rates than those without (odds ratio: 3.62 and 2.87, respectively, P < 0.01). These associations remained significant even after controlling for potential confounders such as age (adjusted odds ratio [AOR]: 1.11; 95% confidence interval [CI]: 1.03-1.20; P = 0.008), sex (AOR: 0.82; 95% CI: 0.31-2.18; P = 0.684), diabetes mellitus (AOR: 2.12; 95% CI: 0.88-5.12; P = 0.091), and chronic kidney disease (AOR: 1.79; 95% CI: 0.75-4.27; P = 0.194)., Conclusion: Positive Tw-aVR and STaVR were found to be associated with in-hospital mortality in HFrEF patients after CABG. These findings suggest that identifying patients with positive Tw-aVR and STaVR may help identify those at higher risk of adverse outcomes and facilitate closer monitoring and more aggressive interventions., (Copyright © 2024 Copyright: © 2024 Nigerian Journal of Clinical Practice.)

- Abstract
Background: Women living with HIV (WLWH) are at increased risk of human papillomavirus (HPV)-related cancers. Throughout Europe, there is great heterogeneity among guidelines for screening programmes, access to HPV testing and HPV vaccination. The aim of this systematic review is to summarize available data on screening and prevention measures for HPV-related anogenital cancers in WLWH across the WHO European Region (WER)., Methods: The systematic review followed the PRISMA guidelines and was registered on Prospero. PubMed, Embase and Web of Science databases were searched to identify available studies, written in English and published between 2011 and 2022. A metanalysis was conducted using random-effects models to calculate pooled prevalence of HPV. Subgroup analyses were conducted according to country and HPV testing., Results: Thirty-four articles involving 10 336 WLWH met the inclusion criteria. Studies were heterogenous in their methodology and presentation of results: 73.5% of studies focused on cervical cancer prevention, and only 4.4% on anal cancer; 76.5% of studies conducted HPV testing as a routine part of screening. The prevalence of high-risk HPV was 30.5-33.9% depending on the detection method used. A total of 77% of WLWH had cervical cytology results reported. Six studies reported the positive association of CD4 cell count <200 cells/μL with HPV prevalence and cervical abnormalities. Anal HPV testing was conducted in <8% of participants. HPV vaccination was completed in 5.6% of women (106/1902) with known vaccination status. There was no information about the vaccination status of the majority of women in the analysed studies (8434/10336)., Conclusion: Data about screening of HPV-related anogenital cancer in WLWH in Europe are heterogenous and lacking, especially in relation to anal cancer. HPV DNA testing is not routinely done as part of screening for HPV-related cancer; guidelines should include indications for when to use this test. Low CD4 count is a risk factor for HPV infection and cytological abnormalities. HPV vaccination data are poor and, when available, vaccination rates are very low among WLWH in Europe. This review concludes that significant improvements are required for data and also consistency on guidelines for HPV screening, prevention and vaccination in WLWH., (© 2024 The Authors.

- Abstract
Warfarin, a widely utilized anticoagulant, is paramount for preventing thromboembolic events in patients with mechanical heart valve replacements. However, its narrow therapeutic index can lead to over-anticoagulation and overdose, resulting in serious health risks. This study examines the efficacy of human prothrombin complex concentrate (PCC) in managing warfarin overdose, in comparison with traditional treatments. A retrospective analysis was conducted on 162 adults who presented with warfarin overdose (INR > 5.0) at a tertiary care hospital between 2016 and 2020. Participants were divided into 2 groups-those treated with PCC (n = 57) and those treated with conventional methods (n = 105), including vitamin K and fresh frozen plasma. The primary outcome was the rate of reaching the target (International Normalized Ratio) INR within 24 hours. Secondary outcomes included transfusion requirements, thromboembolic events, adverse reactions, 30-day mortality, and length of hospital stay. PCC demonstrated significant efficacy, with 89.5% of patients achieving the target INR within 24 hours, compared to 64.8% in the control group (P < .05). The PCC group also had reduced transfusion requirements and a shorter average hospital stay. There was no significant difference in thromboembolic events or adverse reactions between the 2 groups, and the reduced 30-day mortality in the PCC group was not statistically significant. Human prothrombin complex concentrate is associated with rapid reaching the target INR, decreased transfusion needs, and shortened hospitalization, making it a promising option for warfarin overdose management. While the results are encouraging, larger, multicenter, randomized controlled trials are necessary to further validate these findings and optimize PCC administration protocols., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

- Abstract
Background: The majority of people living with HIV in our country are younger men. However, limited data exist for the sexual health of these patients. Knowledge of the epidemiology in this population may improve health outcomes across the continuum of HIV care. The aim of this study was to determine the prevalence of erectile dysfunction (ED) and its association with some clinical and laboratory factors., Methods: A cross-sectional study was conducted using random sampling in men living with HIV (MLWH) at a tertiary hospital in Turkey. Patients were asked to fill out the five-item International Index of Erectile Function (IIEF-5), and blood was collected for HIV viral load, CD4
+ T lymphocyte count, lipids and hormone levels to assess biological aspects at the same clinical visit., Results: A total of 107 MLWH were recruited. Mean age was 40.4 ± 12.4 years. ED was found in 73.8% ( n = 79) of the participants. Severe ED was found in 6.3%, moderate in 5.1%, mild-moderate 35.4%, mild 53.2% of the participants, respectively. The mean age of men with erectile dysfunction was 42.5 ± 12.5 years, while those without erectile dysfunction were 34.5 ± 10 years (p:0.00). ED was detected more frequently in cases with high Low Density Lipoprotein (LDL) levels (p:0.003). There was no statistically significant difference between ED presence and having hormone abnormality. There was a moderate, negative correlation between age and ED score (r: -0.440, p < 0.001). A negative and low correlation was found between triglyceride level and ED score (r: -0.233, p:0.02). The only predictive variable was age in the multivariate analysis [B: -0.155 (95% CI -0.232 to -0.078), p : <0.001]., Conclusions: Our study revealed a high prevalence of ED in the MLWH cohort. Age was found to be the only factor associated with ED. HIV clinicians should consider routine ED screening with validated measures as a part of the follow-up scheme to improve integrated wellbeing in MLWH., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.- Published

- Abstract
Aim: To evaluate the CANLPH score in in-hospital mortality after coronary artery bypass grafting. Materials & methods: The 999 patients were included in this retrospective cohort study. Neutrophil/lymphocyte ratio, C-reactive protein/albumin ratio and platelet/hemoglobin ratio were determined and the CANLPH score was calculated as the sum score of 0 or 1 by the cutoff in each ratio. Results: Twenty-five patients who reached the primary end point were defined as the mortality group and the remaining as the nonmortality group. The CANLPH score was noninferior to the European System for Cardiac Operative Risk Evaluation II in receiver-operating characteristic curve analysis with difference between AUC: 0.0162, standard error (SE): 0.0394, z statistics: 0.682 and p = 0.494. Conclusion: The CANLPH score may be more appropriate in assessing the risk of in-hospital mortality after coronary artery bypass grafting.

- Abstract
Introduction: In this study, we aimed to compare Del Nido cardioplegia (DNC) with blood cardioplegia (BC) in aortic valve replacement., Methods: A two-year single-institute retrospective cohort study was accomplished. Subjects who underwent aortic valve replacement surgery were divided into two groups (DNC and BC) and outcomes were compared., Results: Preoperative demographics and clinical data of the patients in both groups were similar. The time until cardiac arrest following administration of the first dose of cardioplegia was statistically significantly shorter in the BC group (47.0 sec. 25-103) than in the DNC group (63.0 sec. 48-140) (P=0.012). Cross-clamping time was longer in the BC group (48.7±12.3 min. vs. 41.5±11.8 min.) (P=0.041). Cardiopulmonary bypass time was statistically significantly shorter in the DNC group (BC 60.8±18.5 min., DNC 53.7±15.2 min.) (P=0.046). The rate of postoperative use of intravenous positive inotropic support drugs (dopamine, dobutamine, norepinephrine, etc.) for more than two hours was significantly higher in the BC group (20 [23.5%] in the BC group and nine [17.3%] in the DNC group) (P=0.035). Creatine kinase myocardial band and troponin I levels were slightly lower in patients receiving DNC, but no statistically significant difference was detected., Conclusion: Del Nido cardioplegia is safe and can be used efficiently as an alternative to blood cardioplegia in isolated aortic valve replacement surgery.

- Abstract
Background: Coronary collateral circulation (CCC) is a small vascular formation that allows the connection between the different parts of an epicardial vessel or other vessels. The presence of collateral circulation contributes positively to the course of coronary artery disease (CAD). The aim of this study was to investigate the effect of collateral circulation on myocardial injury and clinical outcomes during coronary artery bypass grafting (CABG) in a high-risk patient group., Methods: 386 patients who underwent isolated CABG under cardiopulmonary bypass (CPB) were included in the study. Patients were divided into two groups according to the Rentrop scores (n = 225 poor CCC group; and n = 161 good CCC group). Myocardial injury and postoperative clinical results were evaluated as endpoints., Results: The mean age was 62.9 ± 7.5 years, and 61.6% of all patients were male. Postoperative 30-day mortality rate was significantly higher in poor CCC group (4 [1.7%] and 1 [0.6%], P < .001). The frequency of postoperative intraaortic balloon pump (IABP) use (5 [2.2%] and 1 [0.6%], P < .001), low cardiac output syndrome (LCOS) (28 [12.4%] and 10 [6.2%], P < .001) and postoperative atrial fibrillation (35 [15.6%] and 16 [9.9%], P = .038) were significantly higher in poor CCC group. 12th and 24th hour CK-MB and cTn-I values were found to be significantly lower in the good CCC group., Conclusion: It is inevitable that the CPB circuit and operation have devastating effects on myocardium in CABG operations. The presence of CCC reduces postoperative myocardial injury, low cardiac output syndrome, and mortality rates.

- Abstract
Purpose: In this study, we aim to investigate the efficacy and clinical results of using Del Nido solution (DNS) in coronary artery bypass grafting (CABG) surgery by comparing with intermittent warm blood cardioplegia (IWBC)., Methods: Between March 2017 and February 2018, 297 adult patients who underwent primary isolated CABG surgery with cardiopulmonary bypass (CPB) were included in the study. We used DNS in 112 patients and IWBC was used in 185 patients. We compared both the clinical and the laboratory results., Results: Aortic cross-clamp time, CPB time, and peak glucose level are lower with DNS. But we did not observe any meaningful difference of clinical results between two methods including postoperative myocardial enzyme release., Conclusion: Del Nido cardioplegia was developed for immature heart and pediatric surgery. But in our opinion, it is a good and useful alternative to CABG surgery with similar results to IWBC.
