Varroa destructor mite population dynamics in africanized honeybee (Apis mellifera) colonies in a semi-arid region

Exp Appl Acarol. 2024 Jul 10. doi: 10.1007/s10493-024-00944-1. Online ahead of print.

ABSTRACT

Most published data on mite infestation rates in semi-arid regions have been collected over only 3 or 4 months during a specific period of the year. Therefore, the aim of this study was to observe parasite-host dynamics of hygienic and non-hygienic Africanized bee colonies considering environmental factors that may influence Varroa destructor mite infestation rates in a semi-arid region. To this end, the brood puncture method was applied to 37 colonies, forming two groups, namely G1, encompassing 16 hygienic colonies, and G2, comprising 21 non-hygienic colonies. After forming the groups, 300 worker bees from each colony were examined monthly for mite infestations and the data were correlated with climatological records. The monthly infestation average was considered low, below 10%, except in November, when it reached 12.19% ± 6.45. No statistically significant difference was observed for inter-group infestation rates (P > 0.05). When mite infestation rates were associated with climatic variables, they were linked to colony losses (32%) due to swarming. No significant correlations between hygienic behaviour and parasite infestation rates were noted. Nonetheless, these results support the idea that there is no need to apply acaricides for V. destructor control in Brazil.

Identification of the Core Characteristics of Vulnerable/Hypersensitive Narcissism and its Association with the Dark Triad in a Large International Sample: A Network Analysis Study

Psychiatr Q. 2024 Jul 10. doi: 10.1007/s11126-024-10082-x. Online ahead of print.

ABSTRACT

The current paper aimed to investigate the network structure and centrality indexes of hypersensitive narcissism using the hypersensitive Narcissism Scale (HSN). Additionally, we aimed to explore its relationships with dark triad personality aspects. A globally diverse sample of “53,981” participants (47.9% non-United States responders) completed the HSN and Dark Triad Dirty Dozen scale (DTD). We estimated the network structure across genders to determine the core characteristics of hypersensitive narcissism. Additionally, bridge and central nodes (characteristics) were identified. All analyses were performed using R-Studio programming software. The network comparison test indicated significant differences in the network structures between males and females (Network-Invariance: 0.0489, P < 0.01; Global Strength Invariance: 0.101, P < 0.01). In the network of HSN for male participants, characteristics with the highest strength centrality were “Highly affected by criticism” (HSN.2, strength = 1.08) and “Self-absorbed in personal pursuits” (HSN.8, strength = 1.28). For female participants, “Self-absorbed in personal pursuits” (HSN.8, strength = 1.32) and “privately annoyed by others’ needs” (HSN.10, strength = 1.21) were the highest central characteristics. The assessment of bridge strength indicated that nodes HSN.2 (Highly sensitive to criticism), scoring 0.42, and DTD.1 (Tendency to manipulate for gain, a component of Machiavellianism), scoring 0.428, showed the highest bridge strength values. The current study identified core characteristics of hypersensitive narcissism and its correlation with dark triad personality, revealing gender-specific patterns and bridging symptoms between the two constructs. These findings showed that focusing on these core characteristics may be advantageous in treating individuals exhibiting elevated levels of narcissism.

Acetazolamide therapy in patients with acute heart failure: a systematic review and meta-analysis of randomized controlled trials

Heart Fail Rev. 2024 Jul 10. doi: 10.1007/s10741-024-10417-7. Online ahead of print.

ABSTRACT

Acute heart failure (AHF) often leads to unfavorable outcomes due to fluid overload. While diuretics are the cornerstone treatment, acetazolamide may enhance diuretic efficiency by reducing sodium reabsorption. We performed a systematic review and meta-analysis on the effects of acetazolamide as an add-on therapy in patients with AHF compared to diuretic therapy. PubMed, Embase, and Cochrane databases were searched for randomized controlled trials (RCT). A random-effects model was employed to compute mean differences and risk ratios. Statistical analysis was performed using R software. The GRADE approach was used to rate the certainty of the evidence. We included 4 RCTs with 634 patients aged 68 to 81 years. Over a mean follow-up of 3 days to 34 months, acetazolamide significantly increased diuresis (MD 899.2 mL; 95% CI 249.5 to 1549; p < 0.01) and natriuresis (MD 72.44 mmol/L; 95% CI 39.4 to 105.4; p < 0.01) after 48 h of its administration. No association was found between acetazolamide use and WRF (RR 2.4; 95% CI 0.4 to 14.2; p = 0.3) or all-cause mortality (RR 1.2; 95% CI 0.8 to 1.9; p = 0.3). Clinical decongestion was significantly higher in the intervention group (RR 1.35; 95% CI 1.09 to 1.68; p = 0.01). Acetazolamide is an effective add-on therapy in patients with AHF, increasing diuresis, natriuresis, and clinical decongestion, but it was not associated with differences in mortality.

Comparison of long-term clinical outcomes of bioabsorbable polymer versus durable polymer drug-eluting stents: a systematic review and meta-analysis

Egypt Heart J. 2024 Jul 10;76(1):91. doi: 10.1186/s43044-024-00522-1.

ABSTRACT

BACKGROUND: One million individuals in the USA die from acute myocardial infarction (MI), which currently affects 3 million people globally. The available data about the early and late outcomes of both biodegradable polymer drug-eluting stents (BP-DES) and durable polymer drug-eluting stents exhibit inconsistency. We performed a meta-analysis comparing the safety and efficacy of BP-DES with DP-DES.

METHODS: PubMed, Google Scholar, EMBASE, Cochrane, Ovid Medline, and Clinical Trials.gov databases were used to find out studies comparing BP-DES to DP-DES. All the analyses used the random-effects model.

RESULTS: A total of 18 studies were incorporated in this meta-analysis that involved 28,874 patients, out of which 11,997 received the BP Stent, and the rest of 16,578 received the DP stent. Thorough analyses revealed that the risk of all-cause death was significantly higher in the BP-DES group (5.4% vs 2.7%) (RR 1.22, p 0.02) for two years or less than two-year follow-up. For studies with more than two years of follow-up, all-cause death was 9.07% (599/6603) in BP-DES and 9.47% (531/5602) in the DP-DES group but failed to achieve statistically significant levels (RR 0.97, p 0.58).

CONCLUSIONS: The study revealed no clinically significant (P value was > 0.05) differences in all-cause death, cardiac death, target lesion revascularization (TLR), late stent thrombosis, device-oriented composite endpoint/target lesion failure (DOCE/TLF), myocardial infarction (MI), target vessel MI, target vessel revascularization (TVR), target vessel infarction (TVI) between BP-DES and DP-DES for more than two years of follow-up. Additionally, all-cause death was only outcomes which found to have a statistically significant difference for less than two years of follow-up, while remaining were statistically non-significant.

6,126 hepatectomies in 2022: current trend of outcome in Italy

Langenbecks Arch Surg. 2024 Jul 10;409(1):211. doi: 10.1007/s00423-024-03398-6.

ABSTRACT

PURPOSE: Whether hospital volume affects outcome of patients undergoing hepatobiliary surgery, and whether the centralization of such procedures is justified remains to be investigated. The aim of this study was to analyze the outcome of liver surgery in Italy in relationship of hospital volume.

METHODS: This is a nationwide retrospective observational study conducted on data collected by the National Italian Registry “Piano Nazionale Esiti” (PNE) 2023 that included all liver procedures performed in 2022. Outcome measure were case volume and 30-day mortality. Hospitals were classified as very high-volume (H-Vol), intermediate-volume (I-Vol), low-volume (L-Vol) and very low-volume (VL-VoL). A review on centralization process and outcome measures was added.

RESULTS: 6,126 liver resections for liver tumors were performed in 327 hospitals in 2022. The 30-day mortality was 2.2%. There were 14 H-Vol, 19 I-Vol, 31 L-Vol and 263 VL-Vol hospitals with 30-day mortality of 1.7%, 2.2%, 2.6% and 3.6% respectively (P < 0.001); 220 centers (83%) performed less than 10 resections, and 78 (29%) centers only 1 resection in 2022. By considering the geographical macro-areas, the median count of liver resection performed in northern Italy exceeded those in central and southern Italy (57% vs. 23% vs. 20%, respectively).

CONCLUSIONS: High-volume has been confirmed to be associated to better outcome after hepatobiliary surgical procedures. Further studies are required to detail the factors associated with mortality. The centralization process should be redesigned and oversight.

The role of ureteric indocyanine green fluorescence in colorectal surgery: a retrospective cohort study

Tech Coloproctol. 2024 Jul 10;28(1):83. doi: 10.1007/s10151-024-02955-x.

ABSTRACT

BACKGROUND: Ureteric injury (UI) is an infrequent but serious complication of colorectal surgery. Prophylactic ureteric stenting is employed to avoid UI, yet its efficacy remains debated. Intraoperative indocyanine green fluorescence imaging (ICG-FI) has been used to facilitate ureter detection. This study aimed to investigate the role of ICG-FI in identification of ureters during colorectal surgery and its impact on the incidence of UI.

METHODS: A retrospective cohort study involving 556 consecutive patients who underwent colorectal surgery between 2018 and 2023 assessed the utility of routine prophylactic ureteric stenting with adjunctive ICG-FI. Patients with ICG-FI were compared to those without ICG-FI. Demographic data, operative details, and postoperative morbidity were analyzed. Statistical analysis included univariable regression.

RESULTS: Ureteric ICG-FI was used in 312 (56.1%) patients, whereas 43.9% were controls. Both groups were comparable in terms of demographics except for a higher prevalence of prior abdominal surgeries in the ICG-FI group. Although intraoperative visualization was significantly higher in the ICG-FI group (95.3% vs 89.1%; p = 0.011), the incidence of UI was similar between groups (0.3% vs 0.8%; p = 0.585). Postoperative complications were similar between the two groups. Median stent insertion time was longer in the ICG-FI group (32 vs 25 min; p = 0.001).

CONCLUSION: Ureteric ICG-FI improved intraoperative visualization of the ureters but was not associated with a reduced UI rate. Median stent insertion time increased with use of ureteric ICG-FI, but total operative time did not. Despite its limitations, this study is the largest of its kind suggesting that ureteric ICG-FI may be a valuable adjunct to facilitate ureteric visualization during colorectal surgery.

Association of hemoglobin drift and outcomes in patients with aneurysmal subarachnoid hemorrhage

Neurosurg Rev. 2024 Jul 10;47(1):310. doi: 10.1007/s10143-024-02546-2.

ABSTRACT

The relationship between in-hospital hemoglobin (Hb) drift and outcomes in patients undergoing surgical clipping for aneurysmal subarachnoid hemorrhage (aSAH) is not well studied. This study aims to investigate the association between Hb drift and mortality in this patient population. We conducted a cohort study encompassing adult patients diagnosed with aSAH who were admitted to a university hospital. These patients were stratified into distinct groups based on their Hb drift levels. We employed logistic and Cox proportional hazard models to assess the relationship between Hb drift and outcomes. Additionally, propensity score matching (PSM) was utilized to ensure comparability between patient groups. The discriminative performance of different models was evaluated using C-statistics, integrated discrimination improvement (IDI), and net reclassification improvement (NRI). Overall, our cohort comprised 671 patients, of whom 165 (24.6%) demonstrated an in-hospital Hb drift exceeding 25%. The analyses revealed elevated Hb drift was independently associated with higher likelihood of follow-up mortality (aOR: 3.29, 95% CI: 1.65 to 6.56; P = 0.001) and in-hospital mortality (aOR: 3.44, 95% CI: 1.55 to 7.63; P = 0.002). PSM analysis yielded similar results. Additionally, patients with Hb drift exhibited a notable decrease in survival rate compared to those without Hb drift (aHR: 3.99, 95% CI 2.30 to 6.70; P < 0.001). Furthermore, the inclusion of Hb drift significantly improved the C-statistic (P = 0.037), IDI (2.78%; P = 0.004) and NRI metrics (41.86%; P < 0.001) for mortality prediction. In summary, our results highlight that an in-hospital Hb drift exceeding 25% serves as an independent predictor of mortality in patients who have undergone surgical clipping for aSAH.

Adherence with oral nutritional supplements and influencing factors in postoperative patients with digestive tract tumors: a cross-sectional study

Support Care Cancer. 2024 Jul 10;32(8):501. doi: 10.1007/s00520-024-08711-z.

ABSTRACT

OBJECTIVE: This study aims to use structural equation modeling to explore the pathways and effect sizes of factors influencing the adherence of postoperative patients with digestive tract tumor to oral nutritional supplements, providing a theoretical basis for future nursing intervention measures.

METHODS: A total of 300 postoperative patients with digestive tract tumor within 30 days after surgery were conveniently sampled. Surveys were conducted using a General Information Questionnaire, Morisky Medication Adherence Scale, Digestive System Tumor Patient Nutrition Knowledge-Attitude-Behavior Questionnaire, Multidimensional Social Perception Scale, Beliefs about Medical Questionnaire, and General Self-Efficacy Scale. Structural equation modeling was employed to analyze the factors and pathways affecting adherence with oral nutritional supplements.

RESULTS: The adherence score of postoperative patients with digestive tract tumor to oral nutritional supplements was 1.61 ± 1.38. The structural equation model had a good fit (χ2/df = 2.685, GFI = 0.930, CFI = 0.913, AGFI = 0.887, IFI = 0.915, and RMSEA = 0.075). Nutrition knowledge, social support, medication beliefs, and self-efficacy were found to be factors influencing adherence with oral nutritional supplements in postoperative patients with digestive tract tumor, with total effects of 0.539, 0.264, 0.215, and 0.180, respectively. Nutrition knowledge indirectly affected adherence through self-efficacy and medication beliefs, while social support indirectly affected adherence through self-efficacy.

CONCLUSION: Adherence with oral nutritional supplements in postoperative patients with digestive tract tumor is at a low level. Improving social support, enhancing patients nutrition knowledge, increasing self-efficacy, and strengthening medication beliefs are effective ways to improve patient adherence.

Identification of most representative hub-genes for diagnosis, prognosis, and therapies of hepatocellular carcinoma

Chin Clin Oncol. 2024 Jun;13(3):32. doi: 10.21037/cco-23-151.

ABSTRACT

BACKGROUND: Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths globally. To reduce HCC-related mortality, early diagnosis and therapeutic improvement are essential. Hub differentially expressed genes (HubGs) may serve as potential diagnostic and prognostic biomarkers, also offering therapeutic targets for precise therapies. Therefore, we aimed to identify top-ranked hub genes for the diagnosis, prognosis, and therapy of HCC.

METHODS: Through a systematic literature review, 202 HCC-related HubGs were derived from 59 studies, yet consistent detection across these was lacking. Then, we identified top-ranked HubGs (tHubGs) by integrated bioinformatics analysis, highlighting their functions, pathways, and regulators that might be more representative of the diagnosis, prognosis, and therapies of HCC.

RESULTS: In this study, eight HubGs (CDK1, AURKA, CDC20, CCNB2, TOP2A, PLK1, BUB1B, and BIRC5) were identified as the tHubGs through the protein-protein interaction (PPI) network and survival analysis. Their differential expression in different stages of HCC, validated using The Cancer Genome Atlas (TCGA) Program database, suggests their potential as early HCC markers. The enrichment analyses revealed some important roles in HCC-related biological processes (BPs), molecular functions (MFs), cellular components (CCs), and signaling pathways. Moreover, the gene regulatory network analysis highlighted key transcription factors (TFs) and microRNAs (miRNAs) that regulate these tHubGs at transcriptional and post-transcriptional. Finally, we selected three drugs (CD437, avrainvillamide, and LRRK2-IN-1) as candidate drugs for HCC treatment as they showed strong binding with all of our proposed and published protein receptors.

CONCLUSIONS: The findings of this study may provide valuable resources for early diagnosis, prognosis, and therapies for HCC.

ABSTRACT

Abstinence from sexual practice among youth not only prevents infections, HIV and AIDS, and unplanned pregnancies but also promotes healthy sexual practices and positive youth development. The study aims to explore and describe interventions to improve healthy sexual practices among youth in Vhembe district, Limpopo province. The study utilized a descriptive cross-sectional design with a sample size of 531 determined by the selected formular through probability, simple random technique. Using structured questionnaires for data collection from the participants. Validity was ensured and content and face validity. Reliability was ensured. Data was analysed using SPSS version 28.0. Ethical consideration was ensured during the study. The study results showed that 57.4% of the respondents indicated that they do not discuss their choice of contraceptive with their sexual partner, 80.6% of the respondents indicated that unplanned pregnancy can be prevented by supplying contraceptives programs at clinics and school while 83.2% of the respondents revealed that programs linked with contraceptive services can help prevent unplanned pregnancy. The study highlights the lack of contraceptive choice discussions among sexual partners, exposing them to risks of STIs, HIV and AIDS, and teen pregnancy, urging for improved healthcare access.
