RESUMO

Introduction: The Coronavirus Disease 2019 (COVID-19) pandemic posed critical challenges in providing care to ovarian cancer (OC) patients, including delays in OC diagnosis and treatment initiation. To accommodate for delays in OC surgery, the Society of Gynecologic Oncology (SGO) recommended preferential use of neoadjuvant chemotherapy during the pandemic. The purpose of this study was to assess the association of the COVID-19 pandemic with neoadjuvant chemotherapy use in patients diagnosed with OC. Methods: This retrospective cohort study included patients diagnosed with stage II-IV ovarian cancer of epithelial subtype between 01/01/2017-06/30/2021 at Kaiser Permanente Southern California (KPSC), a large integrated healthcare system in the United States. Ovarian cancer patients diagnosed between 2017-2020 were identified from KPSC's Surveillance, Epidemiology, and End Results (SEER)-affiliated cancer registry. Patients diagnosed in 2021 were identified from the electronic medical records (EMR) using ICD-10 diagnosis codes, followed by medical chart review to validate diagnosis and extract information on histology and stage at diagnosis. March 4, 2020 was used as the cut-off to define pre-pandemic and pandemic periods. Patients diagnosed with COVID-19 between OC diagnosis and treatment completion were excluded. Data on neoadjuvant chemotherapy use were extracted from the cancer registry and EMR, supplemented by chart review. Modified Poisson regression was used to evaluate the association of the pandemic with neoadjuvant chemotherapy use. Results: Of 566 OC patients, 160 (28.3%) were diagnosed in the pandemic period. Patients diagnosed in the pandemic period were slightly younger (mean age 62.7 vs 64.9 years, p=0.07) and had a higher burden of Charlson comorbidities (p=0.05) than patients diagnosed in pre-pandemic period. No differences in time to treatment initiation were observed by pandemic periods. Neoadjuvant chemotherapy use was documented in 58.7% patients during the pandemic period compared to 47.3% in pre-pandemic period (p=0.01). After adjusting for covariates, patients diagnosed in the pandemic period were 29% more likely to receive neoadjuvant chemotherapy than patients diagnosed in pre-pandemic period [RR(95%CI): 1.29(1.12-1.49)]. Discussions: Ovarian cancer patients diagnosed in the COVID-19 pandemic were more likely to receive neoadjuvant chemotherapy than patients diagnosed before the pandemic. Future research on patient outcomes and trends in the post-pandemic period are warranted.

RESUMO

Post-infectious myalgic encephalomyelitis/chronic fatigue syndrome (PI-ME/CFS) is a disabling disorder, yet the clinical phenotype is poorly defined, the pathophysiology is unknown, and no disease-modifying treatments are available. We used rigorous criteria to recruit PI-ME/CFS participants with matched controls to conduct deep phenotyping. Among the many physical and cognitive complaints, one defining feature of PI-ME/CFS was an alteration of effort preference, rather than physical or central fatigue, due to dysfunction of integrative brain regions potentially associated with central catechol pathway dysregulation, with consequences on autonomic functioning and physical conditioning. Immune profiling suggested chronic antigenic stimulation with increase in naïve and decrease in switched memory B-cells. Alterations in gene expression profiles of peripheral blood mononuclear cells and metabolic pathways were consistent with cellular phenotypic studies and demonstrated differences according to sex. Together these clinical abnormalities and biomarker differences provide unique insight into the underlying pathophysiology of PI-ME/CFS, which may guide future intervention.

RESUMO

PURPOSE: Uterine cancer risk is high in breast cancer survivors. Although breast cancer and uterine cancer share some common epidemiological risk factors, association of metabolic syndrome with incident uterine cancer in breast cancer survivors is under-studied. We evaluated the association of metabolic syndrome conditions with second primary uterine cancer in breast cancer survivors. METHODS: In this retrospective cohort study, 37,303 breast cancer patients diagnosed between 2008 and 2020 at Kaiser Permanente Southern California, an integrated healthcare system, were included. Data on cancer-related variables, sociodemographic, and clinical variables were extracted from KPSC's Surveillance, Epidemiology, and End Results (SEER)-affiliated cancer registry and electronic health records, as appropriate. Patients were followed from breast cancer diagnosis until 12/31/2021 for incident uterine cancer. Proportional hazards regression was used to report association [HR (95% CI)] between metabolic conditions and uterine cancer. RESULTS: More than half (53.1%) of the breast cancer survivors had 1-2 metabolic conditions; 19.4% had 3 + , while 27. 5% had no metabolic conditions. Median time to follow-up was 5.33 years and 185 (0.5%) patients developed second primary uterine cancer. Obesity was associated with an elevated uterine cancer risk in the adjusted model [HR (95% CI) 1.64 (1.20-2.25)]. Having 1-2 metabolic conditions (versus none) was not associated with increased uterine cancer risk [adjusted HR (95% CI) 1.24 (0.85-1.82)]; however, there was an increased uterine cancer risk with 3 + metabolic conditions [adjusted HR (95% CI) 1.82 (1.16-2.87)]. CONCLUSION: Although not statistically significant, we found a trend demonstrating greater uterine cancer risk by increasing numbers of metabolic syndrome conditions in breast cancer survivors.

RESUMO

PURPOSE: The purpose of this study was to assess the association of comorbidity burden with overall survival, accounting for racial/ethnic and socioeconomic differences in patients with cancer. METHODS: In this retrospective cohort study, patients newly diagnosed with cancer between 2010 and 2018 were identified from a large health plan in southern California. Cancer registry data were linked with electronic health records (EHR). Comorbidity burden was defined by the Elixhauser comorbidity index (ECI). Patients were followed through December 2019 to assess all-cause mortality. Association of comorbidity burden with all-cause mortality was evaluated using Cox proportional hazards model. Crude and adjusted hazard ratio (HR, 95%CI) were determined. RESULTS: Of 153,270 patients included in the analysis, 29% died during the ensuing 10-year follow-up. Nearly 49% were patients of color, and 32% had an ECI > 4. After adjusting for age, sex, race/ethnicity, cancer stage, smoking status, insurance payor, medical center, year of cancer diagnosis, and cancer treatments, we observed a trend demonstrating higher mortality risk by decreasing socioeconomic status (SES) (P-trend<.05). Compared to patients in the highest SES quintile, patients in the lowest, second lowest, middle, and second highest quintiles had 25%, 21%, 18%, and 11% higher risk of mortality, respectively [(HR, 95%CI): 1.25 (1.21-1.29), 1.21 (1.18-1.25), 1.18 (1.15-1.22), and 1.11 (1.07-1.14), respectively]. When we additionally adjusted for ECI, the adjusted HRs for SES were slightly attenuated; however, the trend persisted. Patients with higher comorbidity burden had higher mortality risk compared to patients with ECI score = 0 in the adjusted model [(HR, 95%CI): 1.22 (1.17-1.28), 1.48 (1.42-1.55), 1.80 (1.72-1.89), 2.24 (2.14-2.34), and 3.39 (3.25-3.53) for ECI = 1, 2, 3, 4, and >5, respectively]. CONCLUSIONS: Comorbidity burden affects overall survival in cancer patients irrespective of racial/ethnic and SES differences. Reducing comorbidity burden can reduce some, but not all, of the mortality risk associated with lower SES.

RESUMO

BACKGROUND: Cervical cancer oncogenesis starts with human papillomavirus (HPV) cell entry after binding to host cell surface receptors; however, the mechanism is not fully known. We examined polymorphisms in receptor genes hypothesized to be necessary for HPV cell entry and assessed their associations with clinical progression to precancer. METHODS: African American women (N = 1,728) from the MACS/WIHS Combined Cohort Study were included. Two case-control study designs were used-cases with histology-based precancer (CIN3+) and controls without; and cases with cytology-based precancer [high-grade squamous intraepithelial lesions (HSIL)] and controls without. SNPs in candidate genes (SDC1, SDC2, SDC3, SDC4, GPC1, GPC2, GPC3, GPC4, GPC5, GPC6, and ITGA6) were genotyped using an Illumina Omni2.5-quad beadchip. Logistic regression was used to assess the associations in all participants and by HPV genotypes, after adjusting for age, human immunodeficiency virus serostatus, CD4 T cells, and three principal components for ancestry. RESULTS: Minor alleles in SNPs rs77122854 (SDC3), rs73971695, rs79336862 (ITGA6), rs57528020, rs201337456, rs11987725 (SDC2), rs115880588, rs115738853, and rs9301825 (GPC5) were associated with increased odds of both CIN3+ and HSIL, whereas, rs35927186 (GPC5) was found to decrease the odds for both outcomes (P value ≤ 0.01). Among those infected with Alpha-9 HPV types, rs722377 (SDC3), rs16860468, rs2356798 (ITGA6), rs11987725 (SDC2), and rs3848051 (GPC5) were associated with increased odds of both precancer outcomes. CONCLUSIONS: Polymorphisms in genes that encode binding receptors for HPV cell entry may play a role in cervical precancer progression. IMPACT: Our findings are hypothesis generating and support further exploration of mechanisms of HPV entry genes that may help prevent progression to cervical precancer.

RESUMO

BACKGROUND: Lower socioeconomic status (SES) affects health care delivery and is associated with worse outcomes. Integrated healthcare systems (IHS) may help reduce barriers to health care and affect outcomes. Our aim was to compare outcomes of colon cancer cases diagnosed at the largest IHS in California, Kaiser Permanente Southern California (KPSC), to other insured patients (OI) to determine how SES influences mortality. METHODS: This retrospective cohort study included insured adults in southern California diagnosed with colon cancer between 2009 and 2014, using data from the California Cancer Registry, and followed through 2017. Main outcome was all-cause mortality. Person-year mortality rates were calculated for two groups, KPSC and OI. Multivariable hazard ratios were calculated for association between SES quintiles and mortality. RESULTS: Total of 15 923 patients were diagnosed with colon cancer, 4195 patients (26.3%) within KPSC and 11 728 patients (73.7%) in OI. The overall mortality rate per 1000 person-years (PY) was lower in KPSC [103.8/1000 PY (95% CI:98.5-109.3)] compared to OI [139.3/1000 PY (95% CI:135.2-143.4)]. Compared to the highest SES group, the lowest SES group did not experience higher mortality risk in the KPSC population, after adjusting for race/ethnicity and other factors (HR, 95% CI = 1.13, .93-1.38). However, in OI patients, lowest and lower-middle SES groups had higher mortality risk compared to the highest SES group (HR, 95% CI = 1.26, 1.13-1.40 and 1.28, 1.16-1.41, respectively). DISCUSSION: Lower SES was associated with higher mortality risk within the OI group; however, within KPSC no such association was observed. Care coordination in IHS settings mitigate SES-related mortality differences.

RESUMO

Mastering manual small-incision cataract surgery (MSICS) for beginner surgeons is difficult. In the initial days of residency or training, surgeons struggle to make a proper scleral tunnel and keratome entry. It commonly results in premature entry and iris prolapse. Most of the literature has shed light on premature entry during tunnel construction by a crescent blade, whereas a significant majority of iris prolapse happens due to improper keratome entry. This novel trypan blue dye-assisted tunnel staining (TBTS) technique helps in proper tunnel demarcation which can reduce the incidence of premature entry with a keratome.

RESUMO

Learning manual small-incision cataract surgery (SICS) is essential for ophthalmic surgeons as it provides an alternative to phaco-emulsification in complicated cases. Nearly 10% of ophthalmic surgeons are left-handed. Left-handed surgeons do face more difficulties because of their laterality, which have been highlighted in various surveys even in other surgical specialities. Surgical training programs, residency programs, and fellowships have traditionally been designed considering the right hand as the dominant hand. Left-handed surgeons (LHSs) are at disadvantage as they are trained by right-handed surgeons (RHSs), which may result in more initial intra-operative errors. Intra-ocular lenses are also designed such that dialing into the bag is relatively difficult for LHSs. Developing customized training modules for LHSs can help them overcome the laterality challenges and enhance their surgical capabilities. In this article, we herein present a brief description of the SICS technique for LHSs, elaborating the crucial steps and customized maneuvers that, if performed differently, may make surgeries easier for them.

RESUMO

Cervical cancer is one of the top malignancies in women around the globe, which still holds its place despite being preventable at early stages. Gynecological conditions, even maladies like cervical cancer, still experience scrutiny from society owing to prevalent taboo and invasive screening methods, especially in developing economies. Additionally, current diagnoses lack specificity and sensitivity, which prolong diagnosis until it is too late. Advances in omics-based technologies aid in discovering differential multi-omics profiles between healthy individuals and cancer patients, which could be utilized for the discovery of body fluid-based biomarkers. Body fluids are a promising potential alternative for early disease detection and counteracting the problems of invasiveness while also serving as a pool of potential biomarkers. In this review, we will provide details of the body fluids-based biomarkers that have been reported in cervical cancer. Here, we have presented our perspective on proteomics for global biomarker discovery by addressing several pertinent problems, including the challenges that are confronted in cervical cancer. Further, we also used bioinformatic methods to undertake a meta-analysis of significantly up-regulated biomolecular profiles in CVF from cervical cancer patients. Our analysis deciphered alterations in the biological pathways in CVF such as immune response, glycolytic processes, regulation of cell death, regulation of structural size, protein polymerization disease, and other pathways that can cumulatively contribute to cervical cancer malignancy. We believe, more extensive research on such biomarkers, will speed up the road to early identification and prevention of cervical cancer in the near future.

RESUMO

BACKGROUND: Evidence on distribution of cardiovascular disease (CVD) risk factors in patients with head and neck squamous cell carcinoma (HNSCC) is limited. We assessed disparities in prevalence and incidence of CVD risk factors in patients with HNSCC. METHODS: Electronic health records (EHR) data on 2262 patients with HNSCC diagnosed between 2012 and 2018 at a NCI-designated cancer center were included. Prevalence of CVD risk factors at baseline and incidence at 1-year post HNSCC diagnosis were assessed using logistic and robust Poisson regression, respectively. RESULTS: At baseline, 31.72% white patients with HNSCC had dyslipidemia, compared to 24.29% blacks (p < 0.008); diabetes was more prevalent in blacks (p < 0.027). Odds of ≥1 prevalent CVD clinical risk factor at baseline was lower in blacks (OR, 95%CI: 0.71, 0.54-0.93) and in rural patients (OR, 95%CI: 0.70, 0.58-0.85). At 1 year, risk of incident diabetes was higher in rural patients (RR, 95%CI: 1.63, 1.21-2.19). CONCLUSIONS: Demographic disparities were observed in distribution of CVD risk factors in patients with HNSCC.

RESUMO

Human papillomavirus (HPV) is a common sexually transmitted disease worldwide. While burden of HPV-associated cancers and mortality is higher in low-income countries, there is limited data about knowledge of it among health care students and professionals. We assessed awareness and knowledge of HPV, its related diseases, and HPV vaccine among 333 participants, composed of 146 medical students (MSs) and professionals (MPs) and 187 nursing students (NSs) and professionals (NPs) using a 40-question survey between July 2018 and February 2019. Surveys were conducted in English language using both paper and an online version. Most participants reported that they had heard of HPV and cervical cancer. However, 91.76% of MPs and 77.97% of MSs, but only 41.11% of NPs and 36.17% NSs reported knowing that HPV types 16 and 18 caused cervical cancer. Likewise, about two-thirds of MPs and MSs reported having the knowledge that HPV 6 and 11 caused genital warts versus only a little over one-fourth of NPs and NSs. Only 55.91% of NPs and 51.61% of NSs were aware that HPV could cause cancer in both men and women, whereas 42.35% of MPs, 64.41% of MSs, 41.76% of NPs, and 40.66% of NSs were aware that the vaccine could be given to both boys and girls. While medical professionals were relatively more knowledgeable about HPV and related diseases, overall, knowledge about the HPV vaccine was low among all groups. This knowledge gap is concerning and warrants further attention to fight HPV-related public health burden in Nepal.

RESUMO

Background: Risk of incident cardiovascular disease (CVD) in head and neck squamous cell carcinoma (HNSCC) patients is under-reported. We assessed the association of HNSCC-related factors and traditional risk factors with 1- and 5-year CVD risk in HNSCC patients without prevalent CVD at cancer diagnosis. Methods: A clinical cohort of 1,829 HNSCC patients diagnosed between 2012 and 2018, at a National Cancer Institute (NCI)-designated cancer center was included. Information on HNSCC-related factors [HNSCC anatomical subsite, stage at diagnosis, treatment, and tumor human papillomavirus (HPV) status] were extracted from the tumor registry. Data on traditional risk factors (hypertension, dyslipidemia, diabetes, tobacco smoking status, and obesity) were extracted from the electronic health records system (EHR) at baseline (HNSCC diagnosis). A composite of ischemic heart disease, heart failure, and ischemic stroke was the outcome of interest in time to event analysis. Hazard ratio (HR) (95% CI) were reported with death as a competing risk. Results: In patients diagnosed with HNSCC, 10.61% developed incident CVD events by 1-year post cancer diagnosis. One-year CVD risk was lower in patients using antihypertensive medications at baseline, compared to patients without baseline hypertension [HR (95% CI): 0.41 (0.24-0.61)]. One-year CVD risk was high in patients receiving HNSCC surgery. Patients receiving radiation therapy had a higher 5-year CVD risk than surgery patients [HR (95% CI): 2.17 (1.31-3.04)]. Patients using antihypertensive medications had a lower 5-year CVD risk than patients without baseline hypertension [HR (95% CI): 0.45 (0.22-0.75)]. Older age and diabetes were associated with increased 1- and 5-year CVD risk. HPV-negative patients were older (p 0.006) and had a higher 5-year cumulative incidence of CVD (p 0.013) than HPV-positive patients. Conclusion: Traditional risk factors and cancer-related factors are associated with CVD risk in HNSCC patients. Future research should investigate the role of antihypertensive medications in reducing CVD risk in HNSCC patients.

RESUMO

Eccrine poroma is a rare tumor arising from sweat glands with common location being soles and palms. We are reporting a case of 70-year male patient with large lower lid mass lesion. Owing to its location and history of growth, malignancy was suspected. Biopsy proved it to be eccrine poroma which is a benign lesion. Complete excision with lid reconstruction was done. Eccrine poroma, though rare, should be kept in the differential diagnosis of eyelid tumors. Owing to the risk of malignant transformation and difficulty in clinical differentiation between poroma and porocarcinoma, wide excision should be done.

RESUMO

BACKGROUND: Anal cancer is rare in the general population in both genders in the US, but an increased incidence of anal cáncer (AC) has been reported among people living with HIV-1 infection (PLWH) and little is known among the population in South US. METHODS: In a retrospective study design, electronic health records from 2006 to 2018 were reviewed in a HIV clinical cohort at the University of Alabama at Birmingham. Associations of demographic, sociodemographic, and HIV-clinical indicators were examined in univariate analyses between high-grade squamous intraepithelial lesions (HSIL) and AC cases and condition-free individuals. Factors for anal/rectal cytology screening tests among PLWH were also assessed over time. Ages at onset of anal cancer were compared with the general US population reported by the National Surveillance, Epidemiology, and End Results Program. RESULTS: A total of 79 anal HSIL (96% men) and 43 cancer (100% men) patients were observed along with 4367 HSIL/cancer-free patients (75.9% men). HSIL (P < 0.0001) and AC (0.0001 < P < 0.01) were associated with being men who have sex with men (MSM). An incidence of 258 per 100,000 person-year was observed among this clinical cohort of PLWH. PLWH who were 45-54 years appeared to be at highest risk of AC (58.1%), as compared to those 55-64 years in the general population. Overall, 79% of PLWH anal cancers were diagnosed among those under 55 years (vs 39.5% in general population) indicating early onset of AC. In total 29.1% of HSIL and 44.2% of AC patients had not received an anal/rectal cytology examination 1 year prior to diagnosis. CONCLUSION: AC incidence among HIV-infected men was 161 times higher than general population with an earlier age of onset/diagnosis. Many patients with AC had missed screening opportunities that could potentially have captured neoplasia in pre-cancerous stages. AC-related screening guidelines need to be integrated into routine clinical care, especially among PLWH at highest risk such as MSM and those with lower CD4 counts.

RESUMO

BACKGROUND: Treatment of congenitally corrected transposition of great arteries (cc-TGA) with anatomic repair strategy has been considered superior due to restoration of the morphologic left ventricle in the systemic circulation. However, data on long term outcomes are limited to single center reports and include small sample sizes. AIM: To perform a systematic review and meta-analysis for observational studies reporting outcomes on anatomic repair for cc-TGA. METHODS: MEDLINE and Scopus databases were queried using predefined criteria for reports published till December 31, 2017. Studies reporting anatomic repair of minimum 5 cc-TGA patients with at least a 2 year follow up were included. Meta-analysis was performed using Comprehensive meta-analysis v3.0 software. RESULTS: Eight hundred and ninety-five patients underwent anatomic repair with a pooled follow-up of 5457.2 patient-years (PY). Pooled estimate for operative mortality was 8.3% [95% confidence interval (CI): 6.0%-11.4%]. 0.2% (CI: 0.1%-0.4%) patients required mechanical circulatory support postoperatively and 1.7% (CI: 1.1%-2.4%) developed post-operative atrioventricular block requiring a pacemaker. Patients surviving initial surgery had a transplant free survival of 92.5% (CI: 89.5%-95.4%) per 100 PY and a low rate of need for pacemaker (0.3/100 PY; CI: 0.1-0.4). 84.7% patients (CI: 79.6%-89.9%) were found to be in New York Heart Association (NYHA) functional class I or II after 100 PY follow up. Total re-intervention rate was 5.3 per 100 PY (CI: 3.8-6.8). CONCLUSION: Operative mortality with anatomic repair strategy for cc-TGA is high. Despite that, transplant free survival after anatomic repair for cc-TGA patients is highly favorable. Majority of patients maintain NYHA I/II functional class. However, monitoring for burden of re-interventions specific for operation type is very essential.

RESUMO

Background: Rurality, race, and age at diagnosis are important predictors in head and neck cancer (HNC) prognosis. However, literature on the associations of rurality and race with age at HNC diagnosis is limited. Data on geographical, racial, and gender disparities in young HNC patients (diagnosed ≤45 years) are also scarce. Materials and Methods: This retrospective study assesses rural-urban, racial, and gender disparities in age at HNC diagnosis, using electronic medical records (Cerner) data of 4258 HNC patients (1538 residing in rural counties and 2720 in urban counties) from National Cancer Institute-designated cancer center in Alabama. Rurality was defined based on 2010 U.S. Census Bureau's rural-urban classification. Logistic regression was used to assess the association of young HNC diagnosis with demographical, behavioral, and clinical variables. ArcGIS 10.2 was used to map geospatial distribution of age and population-adjusted HNC case across rural and urban counties. Results: Patients from rural counties were less likely to be diagnosed at younger age (≤45 years) compared with urban counties (odds ratio [OR] [95% confidence interval (CI)]: 0.74 [0.58-0.93]). Most patients present at stage III/IV (64.9% in rural and 60.2% in urban). Compared with white patients, black patients were 70% more likely to get diagnosed at a young age (95% CI: 1.23-2.35). Young patients were more likely to be females and blacks compared with older patients (p<0.0001). Among oral cavity cancer patients, rural patients were 51% less likely to get diagnosed at young age compared with urban patients (95% CI: 0.27-0.89). Conclusions: Head and neck cancer screening is not routinely conducted so most show up at later stage of cancer. There is also evidence of disparities in age at HNC diagnosis based on rurality, race, and gender; targeted screening can help in reducing these disparities.

RESUMO

BACKGROUND: Little is known about outcomes in patients after being hospitalized for care of cancer or comorbid conditions and the disparity between African-American and White cervical cancer patients. METHODS: Using the national inpatient sample (HCUP-NIS) database of the Healthcare Cost and Utilization Project between 2002-2014, we included 5217 African-American and 21,752 White patients hospitalized with a primary diagnosis of cervical cancer. We examined racial differences in hospitalization outcomes; length of stay (LOS) in hospital, mortality in hospital, post-operative complications in patients who underwent hysterectomy and discharge disposition. Patients were matched on age at primary diagnosis, insurance status, residential region, and median income of residential area, modified Deyo comorbidity index, stage of disease and treatment. Categorical outcomes were analyzed by conditional logistic regression accounting for matched study design and odds ratios (95%CI) were reported. LOS was analyzed using t-test and beta estimate for difference in means was reported. RESULTS: The LOS was significantly lower for Whites compared to African-American cervical cancer patients when matched on demographic only (ß=-0.41, p-value<0.0005, presentation + demographic (ß=-0.41, p-value<0.0006) and treatment + presentation + demographic variables (ß=-0.46, p-value<0.0001). White cervical cancer patients were commonly discharged to other intermediate nursing facility (OR = 1.30, 95%CI = 1.20-1.41, matched on demographic only; OR = 1.31, 95%CI = 1.21-1.43, matched on presentation + demographic; and OR = 1.32, 95%CI = 1.22-1.43), matched on treatment + presentation + demographic). Similar trends were seen in both older (≥65 years) and younger (<65 years) patients, when stratified by age. CONCLUSION: Disparities in hospitalization outcomes in cervical patients are not observed when different characteristics of African-American and White cervical patients are accounted for and matched.

RESUMO

The current study demonstrates oxidative damage and associated neurotoxicity following pH stress in two freshwater carp Labeo rohita and Cirrhinus cirrhosus. Carp (n = 6, 3 replicates) were exposed to four different pH (5.5, 6, 7.5, and 8) against control (pH 6.8 ± 0.05) for 7 days. After completion of treatment, levels of enzymatic (superoxide dismutase [SOD], catalase [CAT], glutathione reductase [GRd]) and non-enzymatic antioxidants (malondialdehyde [MDA], glutathione [GSH]), brain neurological parameters (Na+-K+ATPase, acetylcholinesterase [AcHE], monoamine oxidase [MAO], and nitric oxide [NO]), xanthine oxidase (XO), heat shock proteins (HSP70 and HSP90), and transcription factor NFkB were measured in carp brain. Variation in the pH caused a significant alteration in the glutathione system (glutathione and glutathione reductase), SOD-CAT system, and stress marker malondialdehyde (MDA). Xanthine oxidase was also induced significantly after pH exposure. Brain neurological parameters (MAO, NO, AChE, and Na+-K+ATPase) were significantly reduced at each pH-treated carp group though inhibition was highest at lower acidic pH (5.5). Cirrhinus cirrhosus was more affected than that of Labeo rohita. Molecular chaperon HSP70 expression was induced in all pH-treated groups though such induction was more in acid-stressed fish. HSP90 was found to increase only in acid-stressed carp brain. Expression of NFkB was elevated significantly at each treatment group except for pH 7.5. Finally, both acidic and alkaline pH in the aquatic system was found to disturb oxidative balance in carp brain which ultimately affects the neurological activity in carp. However, acidic environment in the aquatic system was more detrimental than the alkaline system regarding oxidative damage and subsequent neurotoxicity in carp brain.

RESUMO

PURPOSE: To report the incidence, modes of injury, treatment, and short-term outcomes in eyes with post-traumatic elevated intraocular pressure (IOP). METHODS: This was a 5-year hospital-based retrospective study of children ≤16 years who presented with open (OGI) or closed globe injury (CGI) and developed elevated IOP >21 mmHg. Those with a minimum follow up of 3 months were included. Analysis of various parameters such as influence of demographics, mode of injury, IOP, best-corrected visual acuity (BCVA), and effect of medical and surgical treatment on IOP and BCVA was done. RESULTS: Out of 205 pediatric eyes with ocular trauma, 121 (59%) had CGI and the remaining 84 (41%) had OGI. Thirty-two eyes (15.6%) developed elevated IOP. The incidence of elevated IOP following CGI [25 eyes (20.6%)] was significantly higher than that following OGI [7 eyes (8.3%, P = 0.02)]. Hyphema (37.5%) and lens-related mechanisms (18.75%) were the most common causes of elevated IOP. The mean IOP at the time of diagnosis was 29.8 + 6.3 mmHg and reduced to 16.2 ± 2.2 mmHg at last follow up (P < 0.001). Surgical management was required in 12 eyes (37%) and significantly more eyes with CGI required trabeculectomy (24% in CGI vs. 0% in OGI, P = 0.03). Poor baseline vision and vitreoretinal involvement [0.67 line decrement, 95% confidence interval (CI) =0.1-1.25 lines, P = 0.025] increased risk of poor visual outcome. CONCLUSION: Post-traumatic IOP elevation occurred in 15% pediatric eyes, was more common with CGI compared to OGI and nearly one-fourth of eyes with CGI required glaucoma filtering surgery for IOP control. Overall, medical management was needed in 63% eyes and 37% required surgical management. Visual acuity was poor in eyes with OGI due to posterior segment involvement.

RESUMO

BACKGROUND: Patients presenting with hypertensive urgency / emergency (HUE) often have systolic heart failure(SHF). Coronary angiography is routinely done for these patients to rule out obstructive coronary artery disease (Obs-CAD). We performed a retrospective study to investigate predictors of ObsCAD in this population. METHODS: Patients who underwent angiography to investigate SHF and had hospital admission(s) for HUE in the preceding 6 months were included in the study. Chart review was performed to obtain demographic, clinical and imaging / angiographic data. A risk score was formulated based on multivariable logistic regression analysis. RESULTS: 205 patients [age 58.9 ±â€¯14.4 years; 62.4% male; 39.5% diabetic; median EF 25% (Inter Quartile Range: 11)] were included in the study. 33.1% patients (n = 68) had obs-CAD. Patients with obs-CAD were older, diabetic, more likely to have a history of stroke, echocardiographic regional wall motion abnormalities (RWMA) while African Americans were less likely to have obs-CAD. On multivariable analysis, only non-African American race (OR: 2.18; CI: 1.08-4.4) and RWMA (OR: 5.62; CI: 2.47-12.81) remained significant predictors of obs-CAD. A risk score (RANDS) from 0 to 9 was formulated which had a c-statistic of 0.75 with a sensitivity and specificity of 84% and 53% for predicting obsCAD respectively. CONCLUSION: Our results suggest that only a minority of patients with HUE and SHF have obs-CAD. A simple risk score may be used to stratify this population and lower risk individuals may be screened with non-invasive testing instead of invasive catheterization. These results should be validated in large registry populations.
