ABSTRACT

Incorporation of paddy husk biochar (PHBC 350) and Colocasia esculenta (C. esculenta) usage in vertical flow constructed wetlands (VFCWs) for treatment of synthetic wastewater mixed with rhodamine B (RhB) was the focus. To increase the removal efficiency of VFCW, pebbles (0.0125 m³), sand (0.005 m³), and PHBC 350 (0.0075 m³) were used. Setups of VFCWs, S (sand) and SB (sand + biochar [30% v/v]), were established. DO, pH, TS, TDS, TSS, EC, color, turbidity, dye concentration, and RhB removal percentage were evaluated. The measured values of DO, EC, pH, TS, TDS, and TSS in SB were 6.03 mg/L, 1.72 mS/cm, 6.14, 1080 ppm, 860 ppm, and 220 ppm, respectively, in 10 days. Moreover, SB gave a statistical level of RhB removal of 81.5%. All in all, incorporation of biochar into VFCWs created new knowledge to advance the removal performance for wastewater mixed with organic pollutants by understanding its mechanistic dynamics.

ABSTRACT

Microstomia, or small oral aperture, often results from facial burns. This condition appears as scars form within the oral tissue and at the oral commissures, narrowing the oral opening, and leading to mobility, speech, respiratory difficulties, emotional distress, and social interaction challenges. This study examines the presence of reported burn microstomia and its related clinical factors. Pediatric and adult data from a multicenter longitudinal database from 2003-2005 were analyzed to determine the frequency of microstomia at discharge. Summary statistics were used to describe clinical characteristics, demographics, and burn location in pediatric and adult burn survivors. Clinical and burn characteristics were then tested to determine if there was an association with the development of microstomia. Data revealed 4.7% (n = 10) of adult burn survivors (n=214) and 11% (n =10) of pediatric burn survivors (n=91) presented with microstomia at hospital discharge. Those with microstomia had significantly larger TBSA burns, higher rate of inhalation injury, more days on ventilation, and higher rate of adjacent contractures. No differences were found when considering age, sex, race, ethnicity, etiology of burn, or discharge location. Burn size and length of time requiring ventilation were predictive of microstomia. Knowledge of these risk factors suggests therapists should focus on early microstomia prevention, even during times of ventilation, especially in those with larger burn injuries. The high incidence of adjacent contractures demonstrates the impact of cutaneokinematic skin recruitment and suggests areas beyond the perioral should be considered when developing a treatment and prevention program for microstomia following a burn injury.

ABSTRACT

Bisphenol A (BPA), a synthetic compound widely used in plastic manufacturing, has been shown to cause testicular damage and disrupt spermatogenesis. This study aimed to investigate the potential protective effects of astaxanthin (AST) against BPA-induced testicular injury. Four experimental groups of Wistar Albino rats were established (n=8 per group): Control, Sham, BPA, and BPA+AST. At the conclusion of the study, serum samples were analyzed for total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI) [OSI=TOS/TAC], and CRP. Histopathological evaluations included measurements of tubule diameter, Johnsen scoring, and Masson’s trichrome staining. The expression levels of anti-B-cell lymphoma 2 (Bcl-2) and anti-Bcl-2-associated X protein (Bax) were assessed using immunofluorescence (IF) staining and RT-qPCR in testicular tissues. Additionally, tissue collagen (COL1A1, COL3A1) expressions were quantified via RT-qPCR. Results indicated significant increases in TOS, OSI, and CRP levels in the BPA group (p<0.001, p<0.001, and p=0.042, respectively), while TAC levels remained unchanged (p=0.119). AST administration did not significantly alter these biochemical parameters. Histopathological analysis revealed decreased Johnsen scores and tubule diameters in the BPA group; however, these metrics improved in the BPA+AST group. IF analysis confirmed that AST restored the pro-apoptotic Bax/Bcl-2 imbalance induced by BPA (p<0.001), although RT-qPCR results indicated that AST normalized only Bax expression (p<0.001) while Bcl-2 levels remained unchanged (p=0.487). Moreover, COL1A1 and COL3A1 were significantly upregulated in the BPA group (p<0.001 for both), and Masson’s trichrome staining corroborated the presence of fibrosis in this group. AST treatment mitigated these fibrotic changes, as evidenced by reductions in gene expression (p=0.001 for COL1A1 and p=0.005 for COL3A1) and improvements in Masson’s trichrome staining. In conclusion, this study suggests that AST may confer a protective effect against BPA-induced testicular damage by reducing apoptosis and fibrosis; however, changes in oxidative stress markers did not achieve statistical significance. Furthermore, AST may enhance spermatogenesis.

ABSTRACT

The advancement of precision medicine hinges on accurately tailored diagnostic strategies yet estimating reliable confidence intervals (CIs) for the maximal partial Youden Index under verification bias presents considerable challenges, especially within critical false positive rate (FPR) ranges (e.g., (0, 0.1), (0.05, 0.2)) vital for specific clinical applications. While previous work established the partial Youden Index framework, and methods like full imputation (FI), mean score imputation (MSI), inverse probability weighting (IPW), and semiparametric efficient (SPE) address verification bias, robustly integrating these for the partial index across demanding FPRs has needed further development. This paper significantly advances this area by adapting and applying these four bias-correction techniques to estimate the partial Youden Index and its confidence interval (CIs) under verification bias. We systematically evaluate their performance with the proposed (bootstrap-based, MOVER) CI construction approaches. Extensive simulations demonstrate distinct method-specific patterns across verification proportions and FPR ranges, revealing the complexities in achieving reliable estimates. Bootstrap-based CIs exhibit greater robustness to model misspecification, a common clinical uncertainty, while analytical CIs often face undercoverage issues. A cardiovascular disease biomarker analysis corroborates these findings, showing Blood Pressure’s superior discriminatory capability compared to Pulse Rate. Operating under the Missing at Random (MAR) assumption, these results offer crucial, updated guidance for CI estimation in diagnostic studies with incomplete verification, providing significant value where precise evaluation in specific FPR regions is paramount and complete verification is unfeasible. Our findings enhance the statistical foundation for diagnostic test evaluation, extending beyond previous work by comprehensively addressing the partial Youden Index with these updated verification bias correction and CI formula applications.

ABSTRACT

OBJECTIVE: Many studies have highlighted that elevated body mass index (BMI) not only correlates with an elevated likelihood of developing breast cancer (BC) but may also influence patients’ responsiveness to therapeutic regimens and long-term survival outcomes. The impact of BMI on therapeutic response to neoadjuvant chemotherapy (NAC) in patients with BC remains inconclusive. This study seeks to evaluate the effect of BMI on treatment response in the BC population undergoing NAC via a meta-analysis, thereby providing evidence-based support for clinical decision-making.

METHODS: PubMed, Embase, Web of Science, and the Cochrane Library were thoroughly searched until July 29, 2024. Eligible studies were selected as per predefined eligibility criteria. Data extraction and quality assessment were executed via the Newcastle-Ottawa Scale (NOS). Statistical analyses were enabled by R 4.4.1 and Stata 17.

RESULTS: Fifteen studies encompassing 15,235 patients were incorporated. The meta-analysis revealed that in contrast to patients with a normal or low BMI, those who were overweight or obese had a significantly reduced pathlological complete response (pCR) rate (OR: 0.79, p = 0.040). The underweight cohort demonstrated a higher pCR rate in comparison to those with normal BMI (OR: 1.56, p=0.015). Moreover, overweight and obese cohorts displayed a lower pCR rate in contrast to those having normal BMI (OR: 0.83, p < 0.0001).

CONCLUSION: This study indicates that overweight and obese patients tend to exhibit a reduced pCR, highlighting the need for standardized BMI definitions. Future well-designed prospective studies are necessitated to validate these observations.

ABSTRACT

BACKGROUND AND AIM: Accurately estimating alcohol consumption is crucial for clinical decision-making and monitoring treatment outcomes. Phosphatidylethanol in blood (B-PEth), a direct alcohol biomarker, is currently the most reliable indicator of alcohol intake, with a detection window of several weeks; however, the factors influencing the decline of B-PEth levels remain largely unknown. This study aimed to investigate the decline of B-PEth levels during abstinence in patients with alcohol use disorder (AUD) undergoing withdrawal treatment.

METHOD: A total of 100 patients were recruited in withdrawal treatment and followed during three to four weeks of abstinence. Blood samples were collected at baseline and weekly during abstinence to measure B-PEth levels of two homologues (16:0/18:1 and 16:0/18:2). Self-reported alcohol consumption was documented using the Timeline Followback (TLFB) method for 30 days before abstinence and throughout the study period.

RESULTS: B-PEth elimination followed first-order kinetics. The mean half-life was 7.24 days [95% confidence interval (CI) = 6.98-7.53] for 16:0/18:1 and 4.55 days (95% CI = 4.44-4.67) for 16:0/18:2. The rate of decline varied by week, with a longer half-life observed in week three compared with week one. No statistically significant sex differences were detected. The strongest correlation between B-PEth levels and self-reported alcohol consumption was found for data from two weeks prior to abstinence.

CONCLUSION: Elimination of phosphatidylethanol in blood (B-Peth) follows first-order kinetics, with homologue 16:0/18:1 exhibiting a longer half-life than 16:0/18:2. The rate of decline is influenced by the week of alcohol abstinence and B-PEth levels are detectable even in the fourth week of abstinence. The strongest correlation between B-PEth and self-reported alcohol consumption is at two weeks prior to abstinence.

ABSTRACT

Dysregulated calcium ion (Ca²⁺) influx is implicated in diverse channelopathies. Terahertz (THz) waves have been explored as a promising approach to modulate the influx, which primarily target resonant interactions with chemical groups in channels. Here, we demonstrate a strategy that directly regulates the motion of confined Ca²⁺ ions within the selectivity filter via resonant THz waves. We characterize the ions’ axial oscillations, identifying a distinct intrinsic frequency of 1.65 THz and two coherent modes. By tuning a THz electric field to this frequency, we induce a remarkable resonance excitation that lowers the energy barrier between binding sites, achieving a statistically significant enhancement of Ca²⁺ permeation in our model. Meanwhile, we show that the degree of coherence is precisely tunable by the resonant THz field and temperature. Furthermore, quantum mechanics analyses reveal transition frequencies and wavefunctions that validate the observed oscillation modes, confirming that the collective motion exhibits discrete quantum eigenstates. Our results introduce a proof-of-concept, ion-targeted strategy for manipulating Ca²⁺ permeation and propose a theoretical coherence mechanism for high-flux ions transport. This work advances the understanding of ion channel physics via a mechanism-oriented framework that lays the groundwork for exploring novel bio-electromagnetic modulation.

ABSTRACT

OBJECTIVE: This research aims to determine the genital hygiene behaviors and risk factors of women of reproductive age after the earthquake.

METHODS: The descriptive and relationship-seeking research was conducted with 296 women reached online in the Malatya province, where the earthquake in Turkey caused heavy damage. Research data was collected using an online survey form created via Google Forms. Data were obtained using the Personal Information Form and Genital Hygiene Behavior Scale.

RESULTS: In the study, genital hygiene behaviors of women with low education level (p = .004), not working (p = .003), sharing underwear (p = .002), having vaginal itching (p = .006), bathing frequency once a week or less (p = .001), bathing while sitting on a stool (p = .001) and having no knowledge about genital infection (p = .001) were found to be inadequate.

CONCLUSIONS: In the study, it was determined that the genital hygiene behaviors of women of reproductive age were negative after the earthquake. It is recommended that health professionals should not ignore the adverse effects that may occur on women’s genital hygiene behaviors after disasters such as earthquakes and take the necessary initiatives.

ABSTRACT

BACKGROUND: Teicoplanin exhibits complex pharmacokinetics with substantial inter-patient variability. Therapeutic drug monitoring (TDM) is recommended to ensure adequate exposure, yet contemporary data on real-world prescribing practices are scarce. We evaluated current teicoplanin dosing and monitoring practices across UK and Irish hospitals.

METHODS: We conducted a multicentre, retrospective cohort study (Teicoplanin in UK: Study of Hospital Practice; TUcK-SHOP) across 21 hospitals. Adults receiving ≥5 days of intravenous/intramuscular teicoplanin with at least one TDM sample were included. Primary outcome was adherence to local or national dosing guidelines. Secondary outcomes included initial trough level attainment (≥20 mg/L) and laboratory-confirmed toxicity. Multivariable linear regression identified predictors of first trough concentrations.

RESULTS: A total of 391 patients met inclusion criteria (median age 69 years; 57.5% male). Guideline adherence was 66% overall but varied widely between sites (5%-100%). Most patients received three-dose loading (61.3%) with median maintenance dosing of 10.6 mg/kg daily (IQR 7.3-12.1). Median first trough level was 24.6 mg/L (IQR 17.9-33.2); only 40.8% of patients on 6 mg/kg maintenance achieved ≥20 mg/L versus 86.6% on 12 mg/kg (P < 0.001). Independent predictors of higher trough levels included lower creatinine clearance, longer time to TDM sampling, higher loading and maintenance doses, and greater body weight (adjusted R2 = 0.26, P < 0.001). Dose adjustments were required in 30% of patients.

CONCLUSIONS: Teicoplanin prescribing demonstrates significant variation across UK and Irish hospitals. Higher maintenance dosing (10-12 mg/kg) predicts therapeutic target attainment. These real-world data support the need for standardized dosing protocols to optimize teicoplanin therapy.
