RESUMO

BACKGROUND: The study objective is to examine the impact of obesity on frontline carboplatin dosing in the neoadjuvant and adjuvant settings and to evaluate the association of dosing with survival among epithelial ovarian cancer (EOC) patients. METHODS: We selected 1527 women diagnosed with EOC from January 1, 2011 to October 20, 2021 from a nationwide electronic health record-derived de-identified database. The dose reduction of frontline carboplatin was defined as a relative dose intensity (RDI) < 0.85. Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association of RDI with survival overall and by histology. RESULTS: Women with a BMI ≥ 30 kg/m2 versus <30 kg/m2 were more likely to be underdosed (RDI < 0.85) with frontline carboplatin. Underdosing of carboplatin in the neoadjuvant setting was associated with worse survival among women with serous tumours (HR = 1.98, 95% CI = 1.15, 3.42). Underdosing of carboplatin in the adjuvant setting was not associated with survival. DISCUSSION: In the real-world setting, underdosing of carboplatin in the neoadjuvant setting was associated with inferior survival among women with serous tumours. With the increasing utilisation of neoadjuvant chemotherapy in EOC, actual weight-based dosing of carboplatin may be important to improve outcomes in this patient population.

RESUMO

Parental feeding practices influence children's eating behaviors, yet it is not well-understood whether parents' own eating behaviors are associated with their feeding practices. The purpose of this study was to examine associations among parents' eating behaviors, parental feeding practices, and children's eating behaviors. A cross-sectional study was conducted with 76 parents of children from an elementary school in Tampa, FL. Parents completed three questionnaires with topics related to parent eating behaviors, parental feeding practices, and children's eating behaviors. Multiple regression analysis was performed, controlling for demographic covariates. Parents who reported to eat more fruits per day (ß = 0.15), eat more than one kind of fruit each day (ß = 0.33), eat more than one kind of vegetable each day (ß = 0.29), eat 2 or more vegetables at the main meal (ß = 0.36), plan meals (ß = 0.19), and keep vegetables ready for the child to eat (ß = 0.25) indicated that they use more positive reinforcement feeding practices (all p ≤ 0.001). There were significantly positive associations between positive reinforcement and children's eating fruits or vegetables like apples, bananas or carrots as snacks (ß = 1.03) and eating more than one kind of vegetable a day (ß = 1.03; all p < 0.001). No other variables had any significant associations. Findings of this study indicate that there are potential associations among parent's own eating behaviors, feeding practices, and children's eating behaviors. Further research is needed to determine the mechanism of these relationships. Targeting these parental factors may be an effective way to maximize the impact of nutrition interventions on children's dietary behavior changes.

RESUMO

OBJECTIVE: To determine the effect of distance to closest negative margin on survival after pelvic exenteration (PE). METHODS: In this retrospective analysis of PE at Moffitt Cancer Center from 2000 to 2019, baseline characteristics, clinical details, and outcomes were ascertained. Distance to closest negative margin was measured. Close and distant negative margins were defined as <3 mm and ≥3 mm from malignancy to nearest surgical margin, respectively. Overall survival (OS) and progression-free survival (PFS) were determined, and Kaplan-Meier curves were compared. Cox proportional hazards regression was used to examine the association of margin status with OS and PFS. RESULTS: Of 124 PEs with malignancy, 80 (64.5%) had negative margins. Median survival was 62 (95% confidence interval [CI] 27-70) months for negative and 21 (95% CI 15-29) months for positive margins. Of 76 with negative margins and documented margin length, 26 had close and 50 had distant margins. Median survival was 32 (95% CI 14-62) months for close and 111 (95% CI 42-166) months for distant margins. Distant margins were associated with improved OS (p = 0.0054) and PFS (p = 0.0099) compared to close margins. After adjusting for other prognostic factors, patients with distant margins had significantly decreased risk of all-cause mortality (HR 0.39, 95% CI 0.19-0.78; p = 0.008) and progression (HR 0.48, 95% CI 0.23-0.99; p = 0.04) compared to positive margins. No significant differences in OS or PFS were observed between close and positive margins. This survival benefit remained among those with cervical cancer. Median survival in this cohort was 34.1 (95% CI 2.0-69.8) months for close and 165.7 (95% CI 24.5-165.7) for distant margins. CONCLUSIONS: Distant margins following PE are associated with improved OS and PFS compared to close margins.

RESUMO

OBJECTIVE: Although ovarian cancer is a deadly disease, approximately a third of women survive ≥9 years after diagnosis. The factors associated with achieving long-term survival are not well understood. In this study, data from the Surveillance, Epidemiology, and End Results (SEER) program were used to determine predictors of survival trajectories among women with epithelial ovarian cancer and across histotype (high-grade serous carcinoma (HGSC) and non-HGSC). METHODS: Data on 35,868 women diagnosed with epithelial ovarian cancer in 2004-2016 were extracted from SEER. Extended Cox proportional hazards regression was used to estimate overall and histotype-specific associations between patient and tumor characteristics and all-cause mortality within each survival time (t) interval (t < 3, 3 ≤ t < 6, 6 ≤ t < 9, and 9 ≤ t < 13 years). RESULTS: Age at diagnosis, marital status, race/ethnicity, stage, and surgery were more strongly associated with mortality in the short-term survival period, and these associations waned with increasing survival time. Exceptions to this pattern were age >70 years at diagnosis, where a high risk of mortality was observed in both the t < 3 and t ≥ 9 year time periods, and non-Hispanic Asian/Pacific Islanders, where a more pronounced inverse association with mortality was observed in t ≥ 9 years after diagnosis. Similar associations were observed for HGSC, although the waning effect was not apparent for most characteristics. Mortality associations for non-HGSC were more pronounced for stage and race/ethnicity, primarily for non-Hispanic Asian/Pacific Islanders. CONCLUSIONS: Most patient and tumor characteristics were more strongly associated with mortality in the years following diagnosis, but have declining impact with increasing survival time. Given this waning effect, it is critical to identify factors impacting risk of mortality as ovarian cancer patients advance through the survival trajectory.

RESUMO

BACKGROUND: Vegetable 'mandi' (road-side vegetable market) waste was converted to a suitable fermentation medium for cultivation of oleaginous yeast Rhodosporidium toruloides by steaming under pressure. This cultivation medium derived from waste was found to be a comparatively better source of nutrients than standard culture media because it provided more than one type of usable carbon source(s) to yeast. RESULTS: HPLC results showed that the extract contained glucose, xylose and glycerol along with other carbon sources, allowing triauxic growth pattern with preferably usage of glucose, xylose and glycerol resulting in enhanced growth, lipid and carotenoid production. Presence of saturated and unsaturated fatty acid methyl esters (FAMEs) (C14-20) in the lipid profile showed that the lipid may be transesterified for biodiesel production. CONCLUSION: Upscaling these experiments to fermenter scale for the production of lipids and biodiesel and other industrially useful products would lead to waste management along with the production of value added commodities. The technique is thus environment friendly and gives good return upon investment.

RESUMO

In the present study, gold nanoparticles (AuNPs) were synthesized using leaf extract of Syzygium jambolanum and capping agent has been explored. The synthesized AuNPs have been characterized using UV-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), high resolution transmission electron microscopy (HRTEM) and atomic force microscopic (AFM) analysis. The AuNPs show intense surface plasmon resonance (SPR) band at 528 nm and were found to be spherical and hexagonal in shape with particle size ranging from 20-30 nm. Transmission electron microscopy and atomic force microscopy were used to analyze the surface morphology of synthesized AuNPs. The capping ligand has been evaluated using matrix assisted laser desorption ionization-mass spectrometry (MALDI-MS) and gas chromatography-mass spectrometry (GC-MS) analysis.

RESUMO

BACKGROUND: Alzheimer's Disease (AD) is a neurodegenerative disorder characterized by the progressive formation of extracellular amyloid plaques, intracellular neurofibrillary tangles, inflammation, and impaired antioxidant systems. Early detection and intervention are vital for managing AD effectively. OBJECTIVE: This review scrutinizes both in-vivo and in-vitro screening models employed in Alzheimer's disease research. In-vivo models, including transgenic mice expressing AD-related mutations, offer profound insights into disease progression and potential therapeutic targets. A thorough understanding of these models and mechanisms will facilitate the development of novel therapies and interventions for Alzheimer's disease. This review aims to provide an overview of the current experimental models in AD research, assess their strengths and weaknesses as model systems, and underscore the future prospects of experimental AD modeling. METHODS: We conducted a systematic literature search across multiple databases, such as Pub- Med, Bentham Science, Elsevier, Springer Nature, Wiley, and Research Gate. The search strategy incorporated pertinent keywords related to Alzheimer's disease, in-vivo models, in-vitro models, and screening mechanisms. Inclusion criteria were established to identify studies focused on in-vivo and in-vitro screening models and their mechanisms in Alzheimer's disease research. Studies not meeting the predefined criteria were excluded from the review. RESULTS: A well-structured experimental animal model can yield significant insights into the neurobiology of AD, enhancing our comprehension of its pathogenesis and the potential for cutting-edge therapeutic strategies. Given the limited efficacy of current AD medications, there is a pressing need for the development of experimental models that can mimic the disease, particularly in pre-symptomatic stages, to investigate prevention and treatment approaches. To address this requirement, numerous experimental models replicating human AD pathology have been established, serving as invaluable tools for assessing potential treatments. CONCLUSION: In summary, this comprehensive review underscores the pivotal role of in-vivo and in-vitro screening models in advancing our understanding of Alzheimer's disease. These models offer invaluable insights into disease progression, pathological mechanisms, and potential therapeutic targets. By conducting a rigorous investigation and evaluation of these models and mechanisms, effective screening and treatment methods for Alzheimer's disease can be devised. The review also outlines future research directions and areas for enhancing AD screening models.

RESUMO

The present study is an acoustic analysis of Indian English, specifically examining the speech patterns and characteristics of three different groups with different native languages. This study investigates fundamental frequency (fo), fo range, fo variance, formant frequencies, and vowel space size in 42 native male and female speakers of Odia, Bangla, and Hindi. Furthermore, it investigated the potential correlation between fundamental frequency and vowel space, examining whether variations in vowel space size could be influenced by gender-specific perceptual factors. The paper emphasizes that in a multilingual context, gender identification can be efficiently correlated with both fo and formant frequencies. To measure a range of acoustic characteristics, speech samples were collected from the recording task. Analysis was done on PRAAT. The study revealed significant differences between genders for the examined acoustic characteristics. Results indicate differences in the size of gender-specific variations among the language groups, with females exhibiting more significant differences in fo, formant frequencies, and vowel space than males. The findings show no significant correlation between fo and vowel space area, indicating that other features are responsible for large vowel space for females. These findings display significant potential toward creating a robust empirical framework for gender profiling that can be utilized in a wide range of forensic linguistics investigations.

RESUMO

PURPOSE: The onset of labor prior to 37 weeks of gestation is preterm labor. Incidence ranges from 5% to 7% of live births in developed countries, but higher in developing countries (10-13%). Preterm birth is a major threat in perinatal health care, as well as a risk factor for neurological impairment and disability. Considering that infection is the major risk factor for preterm labor in rural areas, this study was performed to assess the cytological changes in the cervical mucus of normal-term and preterm labor cases. METHOD: A hospital-based cross-sectional observational study was conducted in the Department of Obstetrics and Gynecology at a tertiary care center in western Uttar Pradesh (UP), India. The sample size calculated was 90. The neutrophil-to-lymphocyte ratio (NLR) in cervical mucus, along with serum inflammatory biomarkers such as CRP and serum alkaline phosphatase, were compared in both groups. RESULT: The incidence of preterm labor increased with an increase in parity, and progression to preterm delivery is faster in the higher parity group. C-reactive protein (CRP) (p value = < 0.001) and serum alkaline phosphatases (taking 220IU/L as the cutoff value), as well as the NLR (p value < 0.001) in cervical mucus in preterm labor, are significantly higher than those in term labor cases, which can be used to predict preterm labor. CONCLUSIONS: Higher levels of serum alkaline phosphatase (> 220 IU/L) and CRP positivity can be used as prognostic markers. Using a cutoff value of 5 for the NLR in the cervical mucus of preterm labor patients proved to be a highly accurate predictor (82.2%) for preterm labor diagnosis.

RESUMO

Background and Objective: Nasopharyngeal carcinoma (NPC) is a tumor of the head and neck that arises from the mucosal epithelium of the nasopharynx. Epstein-Barr virus (EBV) is a human herpes virus and the necessary cause for NPC. The 5-year survival rate for NPC patients is higher when diagnosed at an earlier stage of disease. Therefore, NPC screening should be prioritized for early detection. The objective of this narrative review is to synthesize the existing literature from the past decade describing evaluations of EBV-based serological markers for NPC screening. Methods: We performed a literature search in PubMed for studies published from 2010 to 2020. Studies were required to be English-language articles. Twelve articles fulfilled all inclusion criteria, including eight studies conducted among the general population in southeastern China, three studies in genetically high-risk Taiwanese families, and one study comparing EBV serology versus circulating EBV DNA for NPC prediction. Key Content and Findings: Studies suggest that EBV-based serology has the potential to be an effective tool to aid in early detection of NPC. The synthesized research also collectively suggests that incorporation of antibody against multiple EBV targets, as well as efforts to optimize assay output, can improve the ability of EBV serological markers to detect NPC. Finally, recent data from the only randomized trial provide preliminary evidence that screening using anti-EBV immunoglobulin A (IgA) antibody may achieve the goal of reducing mortality from NPC. Conclusions: Late diagnosis is one of the reasons for poor survival after an NPC diagnosis. In high-risk areas, early diagnosis aided by EBV antibody could therefore improve survival.

RESUMO

Introduction: Natural carotenoids are well known for their anti-oxidant property and also shown to have antimicrobial and anticancer efficacy. Production of carotenoids from microbial resources mainly from yeast has attracted commercial interest. Breast cancer has the highest incidence among women, and therapy resistance and lack of effective therapeutic strategies are major treatment bottlenecks, particularly for triple-negative subtypes. Yeast carotenoids are recently being evaluated for affordable, non-toxic, natural product-based therapies. In the present study, we have shown an environment-friendly and inexpensive method for carotenoid production from yeasts, utilizing "mandi" wastes, and investigated the biomedical properties of carotenoids, particularly antineoplastic properties. Methods: Vegetable "mandi" waste was used to prepare waste hydrolysate, a culture medium, in which oleaginous red yeast Rhodosporidium sp. was grown. Carotenoid pigments were extracted using the solvent extraction method and analyzed by UV spectroscopy, thin-layer chromatography (TLC), and high-performance liquid chromatography (HPLC). Antimicrobial, antioxidant, and anticancer activities of the extract were evaluated, followed by in silico docking and absorption, distribution, metabolism, and excretion/toxicity (ADME/T) studies. Results: Carotenoid extract was found to be composed of three main pigments-ß-carotene, torulene, and torularhodin. Extract exhibited significant antioxidant, antimicrobial, and anti-breast cancer activities in vitro while being biocompatible. Interestingly, carotenoids have shown better efficacy in triple-negative breast cancer (TNBC) cells than ER+PR+ cells. In silico evaluation predicted binding with breast cancer-specific molecular targets, specifically the three components showed good binding energy toward VEGF receptors and good drug likeliness properties, as well as less toxicity. Discussion: This is the first report on anti-breast cancer activities, particularly targeting TNBC cells by red yeast carotenoids (ß-carotene, torulene, and torularhodin) produced via a sustainable environment-friendly bioprocess utilizing waste hydrolysate.

RESUMO

BACKGROUND: Patients with HIV (PHIV) are living longer with the adoption of anti-retroviral therapy. As such, more patients are presenting with advanced cancer diagnoses, including peritoneal surface malignancies. The objective of this study was to assess the safety of CRS/HIPEC in this cohort of patients. CASE: Five PHIV were identified, four of whom underwent CRS/HIPEC. Primary sites of disease were low-grade appendiceal mucinous tumors in three patients and peritoneal mesothelioma in the other. Operative time ranged from 7 to 14 h. One patient developed a Clavien grade II complication postoperatively. There was no instance of neutropenia identified. One patient died of disease 19 months after surgery; the remaining three patients are alive 11, 21, and 33 months postoperatively. CONCLUSION: This study demonstrates that CRS/HIPEC can be performed in PHIV without prohibitive complications and operative recovery approximates that of non-HIV patients. Though more study is needed, HIV should not preclude a patient from being offered CRS/HIPEC.

RESUMO

We evaluated antibody against Epstein-Barr virus glycoproteins (gp350, gH/gL, gB, gp42) in 97 nasopharyngeal carcinoma (NPC) cases and 97 cancer-free controls. Each unit increase in log-transformed antibody against gp350 and gH/gL was associated with 2.27 (95% confidence interval [CI], 1.20-4.29) and 2.18 (95% CI, 1.22-3.90) higher odds of NPC, respectively. This association was more apparent for NPC diagnosed within 5 years of antibody measurement.

RESUMO

Elevated cancer-specific mortality in PWH has been demonstrated for non-AIDS-defining malignancies. However, additional clinical endpoints of interest, including patient-reported outcomes (PROs), have not been systematically examined in PWH and cancer. We evaluated differences in patient-reported symptomology between cancer patients with versus without HIV using data from 12,529 patients at the Moffitt Cancer Center, including 55 with HIV. The symptoms were assessed using the Edmonton Symptom Assessment Scale (ESAS), which asks patients to rank 12 symptoms on a scale of 1−10, with scores ≥7 considered severe. The responses across all questions were summed to create a composite score. Vital status through t July 2021 was determined through linkage to the electronic health record. PWH reported a higher composite ESAS score on average (44.4) compared to HIV-uninfected cancer patients (30.7, p-value < 0.01). In zero-inflated negative binomial regression models adjusted for cancer site, sex, and race, the composite ESAS scores and the count of severe symptoms were 1.41 times (95% CI: 1.13−1.77) and 1.45 times (95% CI: 1.09−1.93) higher, respectively, in cancer patients with HIV. Among PWH, higher ESAS scores were associated with mortality (p-value = 0.02). This is the first demonstration of uniquely poor PROs in PWH and cancer and suggests that patient symptom monitoring to improve clinical endpoints deserves further study.

RESUMO

BACKGROUND: Tumor-infiltrating lymphocytes (TIL) confer a survival benefit among patients with ovarian cancer; however, little work has been conducted in racially diverse cohorts. METHODS: The current study investigated racial differences in the tumor immune landscape and survival of age- and stage-matched non-Hispanic Black and non-Hispanic White women with high-grade serous ovarian carcinoma (HGSOC) enrolled in two population-based studies (n = 121 in each racial group). We measured TILs (CD3+), cytotoxic T cells (CD3+CD8+), regulatory T cells (CD3+FoxP3+), myeloid cells (CD11b+), and neutrophils (CD11b+CD15+) via multiplex immunofluorescence. Multivariable Cox proportional hazard regression was used to estimate the association between immune cell abundance and survival overall and by race. RESULTS: Overall, higher levels of TILs, cytotoxic T cells, myeloid cells, and neutrophils were associated with better survival in the intratumoral and peritumoral region, irrespective of tissue compartment (tumor, stroma). Improved survival was noted for T-regulatory cells in the peritumoral region and in the stroma of the intratumoral region, but no association for intratumoral T-regulatory cells. Despite similar abundance of immune cells across racial groups, associations with survival among non-Hispanic White women were consistent with the overall findings, but among non-Hispanic Black women, most associations were attenuated and not statistically significant. CONCLUSIONS: Our results add to the existing evidence that a robust immune infiltrate confers a survival advantage among women with HGSOC; however, non-Hispanic Black women may not experience the same survival benefit as non-Hispanic White women with HGSOC. IMPACT: This study contributes to our understanding of the immunoepidemiology of HGSOC in diverse populations.

RESUMO

Plasmodial resistance to a variety of plant-based antimalarial drugs has led toward the discovery of more effective antimalarial compounds having chemical or biological origin. Since natural compounds are considered as safer drugs, in this study, yeast strains were identified and compared for the production of carotenoids that are well-known antioxidants and this metabolite was tested for its antiparasitic activity. Plasmodium falciparum 3D7 strain was selected as the target parasite for evaluation of antimalarial activity of yeast carotenoids using in vitro studies. Data were analyzed by FACS (fluorescence-activated cell sorter) and counted via gold standard Giemsa-stained smears. The extracted yeast carotenoids showed a profound inhibitory effect at a concentration of 10-3 µg/µl and 10-4 µg/µl when compared to ß- carotene as control. SYBR Green1 fluorescent dye was used to confirm the decrease in parasitaemia at given range of concentration. Egress assay results suggested that treated parasite remained stalled at schizont stage with constricted morphology and were darkly stained. Non-toxicity of carotenoids on erythrocytes and on human liver hepatocellular carcinoma cells (HepG2 cells) was shown at a given concentration. This report provides strong evidence for antimalarial effects of extracted yeast carotenoids, which can be produced via a sustainable and cost-effective strategy and may be scaled up for industrial application.

RESUMO

Particulate-bound poly-aromatic hydrocarbons (PAHs) are of great concern due to their mutagenicity and carcinogenicity effect on human health. In this context, identification, quantification and inhalation cancer risk (ICR) assessment due to PM10- and PM2.5-bound PAHs has been carried out at six monitoring stations in a critically polluted Jharia coalfield/Dhanbad City. Identification of pollution sources at study area has been performed by using PCA statistical methods. Air quality index (AQI) and air quality health index (AQHI) were calculated based on the concentration levels of PM10. Location-wise direct comparison between AQI, AQHI and ICR was performed to analyse the risk levels. Consequently, maximum concentration levels of particulate (PM2.5 and PM10)-bound total PAHs (400 and 482 ng/m3) were recorded at the monitoring station Lodna Thana, followed by Bank More and Sijua Stadium, respectively. It was also observed that mine fire-affected station Lodna Thana was exaggerated with presence of PAHs due to wood and open coal burning activities. Moreover, about 1000 and 889 cases of inhalation cancer risk were estimated due to direct exposure of PM10- and PM2.5-bound PAHs in the study area, respectively. Active mine fire-affected station Lodna Thana was recorded with maximum probability of lung tumour due to inhalation cancer risk. This study has reported higher AQHI at station Dugdha Basti, Lodna Thana and Bank More, which results increased number of tumours due to ICR. This result concludes that Jharia coalfield/Dhanbad City are not only critically polluted area but it is also an inhalation cancer prone area due to direct exposure of active mine fire.

RESUMO

This study was a cross-sectional study to examine problematic mealtime behaviors among children with autism spectrum disorder (ASD) in Florida. Forty-one parents completed a 48-item survey. The mean age of their children was 8.1 years and 73% were male. The data were divided and compared by age group: Ages 2⁻6, 7⁻11, and 12⁻17. Data from the 3- to 6-year-old children were extracted and compared with the references from Provost et al. (2010). There were age differences in eating difficulties at home (p = 0.013), fast food restaurants (p = 0.005), and at regular restaurants (p = 0.016). The total mealtime behavior score was significantly higher in early childhood (p < 0.001) and mid-childhood (p = 0.005) than adolescents. More parents of ages 3⁻6 with ASD reported difficulties with breastfeeding (p < 0.01); concerns about eating (p < 0.001); difficulties related to mealtime locations (p < 0.05), craving certain food (p < 0.05), and being picky eaters (p < 0.01) compared to typically developing children. The total mealtime behavior score was significantly higher in children with ASD than typically developing children (p < 0.001). The results indicate that early childhood interventions are warranted and further research in adolescents is needed.
