Comparison of In-Hospital Mortality and Neurosurgical Intervention Between Intracranial Gunshot Wounds Arising From Long Guns and Handguns: A Propensity Score Matched Study.

Patients with intracranial gunshot wounds (IC-GSWs) often present with severe neurological injuries requiring prompt neurological evaluation. Neurosurgical intervention is reserved for those with reasonable chances of survival. Handguns and long guns, such as shotguns and rifles, have differing mechanisms of injury which may influence surgical candidacy and outcomes. This study aims to compare rates and types of neurosurgical intervention and inpatient outcomes in patients with IC-GSWs handguns and long guns. The National Trauma Data Bank was retrospectively queried for patients with IC-GSWs from 2017 to 2019. Patients with long gun IC-GSWs were propensity score matched with those with handgun IC-GSWs based on patient demographics, comorbidities, insurance status, injury extent and severity, and hospital trauma level. Group differences were compared using Student's t-tests and Pearson's χ2 tests, and multivariable logistic regression was used to identify predictors of in-hospital mortality. Overall, patients in the long gun group were more likely to undergo neurosurgical intervention (21% vs 17%, P = .02). Following propensity score matching, the long gun group had lower rates of in-hospital mortality (35% vs 43%, P < .01), lower rates of cardiac arrest (5% vs 8%, P = .02), and lower rates of reoperation (0% vs 2%, P = .02) than the handgun group. In multivariable regression, independent predictors of survival included long gun IC-GSWs (odds ratio [OR] 0.65, CI 0.52-0.83), neurosurgical foreign body removal (OR 0.44, CI 0.33-0.58), intracranial debridement (OR 0.47, 0.33-0.67), and craniectomy (OR 0.46, CI 0.34-0.63). Patients with IC-GSWs present to the hospital with severe neurological injury. Neurosurgical intervention was independently associated with decreased mortality. After matching, patients with long gun IC-GSWs experienced lower in-hospital mortality rates compared with those from handguns. This study suggests that patients suffering from long gun IC-GSW may respond particularly well to neurosurgical intervention and firearm type should be considered when determining neurosurgical candidacy.

Emphasizing the Importance of Naproxen Prophylaxis May Decrease the Rate of Heterotopic Ossification After Hip Arthroscopy

To investigate the incidence of heterotopic ossification (HO) in patients prescribed prophylactic nonsteroidal anti-inflammatory drugs (NSAIDs), both before and after the introduction of a standardized education protocol. A retrospective review was conducted using a database of hip arthroscopy patients treated by a single surgeon at an academic hospital from 2015 to 2023. The inclusion criteria were (1) primary hip arthroscopy for the treatment of femoroacetabular impingement, (2) completion of a 2-week course of prophylactic postoperative NSAIDs (500 mg of naproxen twice daily), and (3) availability of follow-up radiographs at the 6-month postoperative visit. The control cohort was merely prescribed the postoperative prophylactic NSAIDs, whereas the intervention cohort also received dedicated in-person education, emphasizing the importance of NSAID adherence. The presence of HO was determined through review of follow-up radiographs. Standard descriptive statistics were used to describe the findings. Both the control and intervention groups consisted of 200 continuous hip arthroscopy patients, with the control group treated from 2015 to 2017 and the intervention group treated from 2020 to 2023. Within the control group, 10 cases of HO (5%) were detected. Within the intervention group, 2 cases of HO (1%) were found. The Pearson χ2 test with Yates continuity correction produced a value of 4.21, with a P value of .04. In this study, we found a significantly lower incidence rate of HO in patients who received standardized education on the importance of NSAID compliance versus those who did not. This finding suggests that patient education may play a contributory role in reducing the incidence of HO after hip arthroscopy. Level III, comparative cohort study.

Comparison of polypharmacy and potentially inappropriate medication use in older adults with and without dementia receiving residential medication management reviews.

Among residents who had a residential medication management review (RMMR), there is a lack of studies assessing exposure to polypharmacy and potentially inappropriate medications (PIMs) in people with dementia. This study compared the exposure to polypharmacy and PIMs in residents with dementia and without dementia receiving RMMR. A retrospective analysis was performed using data of 16,261 residents living in 343 Australian residential aged care facilities who had an RMMR in 2019. Medication use was assessed as polypharmacy (defined as ≥9 medications) and use of ≥1 PIMs using the 2019 updated Beers criteria. Dementia diagnosis was determined with ICD-10 coding from medical records. Descriptive analyses reported resident demographics and patterns of medication use. Pearson's χ2 tests and logistic regression analysis were conducted to compare medication exposure between residents with and without dementia. Among 16,261 residents, 6781 (42%) had dementia. Residents with dementia were significantly more likely to be exposed to polypharmacy and PIMs, compared to those without dementia (74% vs. 70% and 83% vs. 73%, p < .001 respectively). Residents with dementia had 1.31 times the odds of exposure to polypharmacy (adjusted OR: 1.31, 95% CI: 1.22-1.41, p < .001) and 1.88 times the odds of being prescribed ≥1 PIMs than people without dementia (adjusted OR: 1.88, 95% CI: 1.73-2.04, p < .001). In a study of residents receiving RMMR, polypharmacy and PIMs were highly common, and those with dementia were more likely to be exposed to inappropriate polypharmacy. There is a need for targeted deprescribing strategies to immediately address inappropriate prescribing in residents, particularly those living with dementia.

Cytologic Parameters in Predicting the Outcome of Atypical Glandular Cells on Papanicolaou Smears: A Single-Institutional Experience.

Atypical glandular cells (AGCs) diagnosis on Pap (Papanicolaou) smears are uncommon and may represent various benign and malignant lesions. This study aims to report the incidence of AGC on Pap smear, to study the relationship of AGC with malignancy, and to determine cytomorphological features that help in predicting malignancy. Retrospective analytical study conducted in the Department of Oncopathology at Tertiary Cancer and Research Institute. In this retrospective study, we included cases diagnosed with AGC between July 2017 to July 2022. All slides were reviewed and subclassified according to the Bethesda 2014 classification system (TBS). The predetermined cytomorphological features observed in the smears were recorded. The follow-up histopathological diagnoses of the cases were retrieved. The significant cytomorphological and clinicopathological findings for malignancy were determined. Pearson χ2 test with SPSS software version 22 to compare cytologic features of cases with benign and malignant follow-up. The significant cytomorphological features observed in neoplastic cases were cells in 3-dimensional clusters, nuclear overlapping, reniform nucleus, irregular nuclear membrane, increased nuclear size, single macronucleoli, engulfed neutrophils, and prominently vacuolated cytoplasm. The diagnosis of AGC on cytology is associated with clinically significant lesions, and cytomorphologic parameters can be used to predict the benign and malignant outcome.

General features of existential depression in youth

IntroductionThe axial symptom of existential depression in youth is overvalued ideas about the meaninglessness of human life, its inconsistency with a certain “spiritual self-ideal”; ideas of humiliation, insolvency, low value, imperfection of society are noted, which accompanies varying degrees of severity of suicidal thoughts. The high suicidal risk, insufficient knowledge of such conditions makes it important to study.ObjectivesDetermination of the clinical and psychopathological consequences of existential depression in youth.Methods53 male 16-25 years old with F31.3, F31.4, F32, F33 (ICD-10) with the existential depression were examined with clinical-psychopathological method, psychometric assessment of depression was carried out using the HDRS scale, assessment of suicidal intentions - using the C-SSRS scale. Also were analyzed: premorbid personality structure, hereditary burden in first-degree relatives, the role of exogenous provocations. Statistical data processing was carried out using the STATISTICA software package 10.0 for WINDOWS (StatSoft, USA, was used Pearson χ² test, Student t-test. The critical level of statistical significance is p ≤ 0.05.ResultsA significant role in the manifestation of existential depression was played by exogenous provocations (χ²=9.47, p=0.05), especially psychotrauma: the most common were the death of a close relative or friend, unrequited love, and failure to enter the desired university.According to the premorbid personality structure schizoid (56.7%) and psychasthenic personalities (30.2%) prevailed. When assessing hereditary burden (χ²=9.59 p=0.047), pathocharacterological features were noted in first-degree relatives in 32.1% cases, affective disoders in 26, 4%.In terms of social and labor status (χ²=9.47, p=0.05), university students naturally predominated (56.6%). The average age of onset of depression was 17.8 ± 1.2 years, duration 3.7 ± 1.5 months. Non-suicidal self-harm was observed in 32.1%, especially in the initial stages of depression. Among suicidal tendencies (χ²=9.58, p=0.048), anti-vital thoughts (50.9%) and passive suicidal thoughts (34%) dominated; 5.7% of patients attempted suicide. On the HDRS scale, patients scored an average of 18.2±1.7 points, which reflected the severity of depression; the total score on the C-SSRS scale was 2.12±0.34.ConclusionsIn the formation of existential depression, a significant role of exogenous provocations, especially psychotrauma, was discovered; a high suicidal risk was confirmed. Existential depressive states differed in duration; patients of the identified typological varieties scored high on the HDRS and C-SSRS scales. In the future, it is planned to study the follow-up group for the purpose of a detailed analysis of the dynamics of such conditions and their nosological affiliation.Disclosure of InterestNone Declared

A test-based strategy for early return to work for health-care workers with COVID-19 during the Omicron wave, Brunei Darussalam, 2022.

This paper summarizes and evaluates a test-based strategy for early return to work for health-care workers (HCWs) with mild coronavirus disease in Brunei Darussalam during the Omicron wave in February 2022 and compares the characteristics of HCWs by how long it took them to return to work. The early return-to-work strategy involved testing on day 3 of infection with reverse transcription-polymerase chain reaction and with a rapid antigen test on days 5 and 6 or days 5 and 7. Data about infected HCWs were extracted from the Ministry of Health's public health surveillance database. Percentages and proportions were used for descriptive statistics, and Pearson's χ2 test and the paired t-test were used to compare return-to-work patterns with demographic factors and vaccination status of the HCWs, as well as between cycle threshold (Ct) values and occupational groups of HCWs. From 15 February to 15 March 2022, a total of 1121 HCWs were notified as being infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Of these, 175 (15.6%) were able to return to work on day 4 of their infection, 153 (13.6%) on day 6 and 268 (23.9%) on day 7; 525 (46.8%) required 10 days of home isolation. Statistically significant associations were observed between return-to-work periods and occupational group (P<0.01) and Ct value (P<0.01), but not between return to work and age, sex or vaccination status. This test-based strategy ensured a balance between mitigating a shortage of HCWs and enabling them to return to work early without compromising their safety and that of their patients.

Posterior Reversible Encephalopathy Syndrome in Eclamptic Patients: The Relationship between Blood Pressure, Cranial Involvement, and Seizure Recurrence

Objectives: Posterior reversible encephalopathy syndrome (PRES) is a clinic radiological disorder characterized by headache, epileptic seizure, encephalopathy, visual impairment, and focal neurological deficits. Gestational hypertension, which is a significant risk factor for PRES, may cause significant morbidity and mortality among pregnant women. Design: Twenty-four patients with PRES caused by eclampsia who were admitted to our hospital in the last 5 years were included in this study. Participants/Materials, Setting, Methods: Blood pressure at admission, the number of regions with vasogenic edema in the brain, and recurrent seizures were noted. Patients were divided into three groups: mild, moderate, and severe. Results: Using Kruskal-Wallis and Pearson χ2 tests, there was no statistical significance between the groups in terms of cranial involvement (p = 0.471). However, binary logistic regression analysis showed that seizure recurrence increased in correlation with blood pressure (p = 0.04). Limitations: PRES is a rare syndrome associated with several etiologies. In our study, only patients with PRES due to eclampsia were included. Therefore, the number of included patients was limited (24 participants). Conclusion: PRES may occur in eclamptic patients with mild, moderate, or severe blood pressure values. Evaluation by magnetic resonance imaging is needed to confirm the diagnosis. Early and rapid treatment is essential for reducing morbidity and mortality among pregnant women.

Abstract 4804: Prevalence of anal HPV infection in women attending a gynecology and colposcopy clinic: Assessing the potential impact of HPV vaccination

Abstract Human papillomavirus (HPV) accounts for over 80% of anal cancer cases. In the effort to prevent HPV-related cancers, the 9-valent HPV vaccine emerged as a crucial intervention, targeting HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58; the previous 4-valent (types 6,11,16,18) and 2-valent (types 16, 18). This study involved 213 women aged 21-50 attending gynecology and colonoscopy clinics in San Juan, Puerto Rico. The study assessed anal HPV prevalence and analyzed vaccination status-related differences. Anal swabs were collected for HPV testing using the ATILA AmpFire, targeting 17 HPV types. This method identified 15 high-risk HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, and 68) and two low-risk HPV types (6 and 11). Prevalence of any HPV, HR-HPV, and LR-HPV, and of specific HPV types were calculated by overall and vaccination status. Differences were assessed for statistical significance (p&amp;lt;0.05) using Fisher's exact or Pearson χ2 test. The mean age of women was 36.0 ± 5.9 years. Overall, 19.7% (n=44) had received the HPV vaccine; among them, 52.2% (n=23) had received the 4-valent vaccine, 2.3% had received the 2-valent vaccine, 2.3% had received the 9-valent vaccine, and 43.2% were uncertain about their specific HPV vaccine type. The prevalence of anal HPV infection was 68.5% for any HPV, 61.5% for HR-HPV, and 15.0% for LR-HPV. The most prevalent HR-HPV types were HPV 56 (13.2%), HPV 68 (11.7%), and HPV 66 (11.2%). There were no statistically significant differences in the prevalence of any HPV, HR-HPV, and LR-HPV between vaccinated and unvaccinated women. The most common HR-HPV type among vaccinated were HPV 66 (20.5%), HPV 31 (18.2%), HPV 56 (15.9%), while the most common among unvaccinated women were HPV 56 (12.4%), HPV 68 (12.4%), and HPV 16 (12.4%). Additionally, when evaluating as a grouped variable, the HPV genotypes covered by the 4-valent, unvaccinated women had a significantly higher prevalence of these types as compared to those vaccinated (28.9% vs. 13.6%, respectively, p-value =.03). The unvaccinated women showed a lower prevalence for HPV types covered by the 9-valent vaccine compared to the vaccinated cohort (43.2% vs. 45.5%). However, this difference was not statistically significant. We found a high prevalence of anal HPV among these women, with lower prevalence of 4-valent and 2-valent HPV types among vaccinated women, evidencing the pivotal role of HPV vaccination. Future research should assess the 9-valent vaccine's long-term effectiveness against more HPV types.

The occurrence of immune-related adverse events is an independent risk factor both for serum HBsAg increase and HBV reactivation in HBsAg-positive cancer patients receiving PD-1 inhibitor combinational therapy.

Previous studies have suggested the potential of PD-1/PD-L1 inhibitors in the treatment of chronic HBV infection. However, since phase III clinical trials have not yet been announced, additional clinical insights may be obtained by observing changes in serum hepatitis B surface antigen (HBsAg) and HBV-DNA levels in cancer patients undergoing PD-1 inhibitor therapy. To explore the effects of PD-1 inhibitor combinational therapy on serum HBsAg and HBV-DNA levels, investigate the incidence of HBsAg loss, HBV reactivation (HBVr), and immune-related adverse events (irAEs), and identify the risk factors associated with significant HBsAg fluctuations and HBVr. A retrospective study including 1195 HBsAg-positive cancer patients who received PD-1 inhibitors between July 2019 and June 2023 was conducted, and 180 patients were enrolled in this study. Serum HBsAg levels before and after PD-1 inhibitor administration were compared across different subgroups. The Pearson χ2 or Fisher exact test was performed to investigate the relationships between categorical variables. Univariable and multivariable analysis were performed to identify the risk factors associated with significant HBsAg fluctuations and HBVr. With the concurrent use of antiviral agents, serum HBsAg levels decreased (Z=-3.966, P < 0.0001) in 129 patients and increased (t=-2.047, P=0.043) in 51 patients. Additionally, 7 patients (3.89%) achieved serum HBsAg loss. Virus replication was suppressed in most of the enrolled patients. When divided patients into different subgroups, significant HBsAg decreases after PD-1 inhibitor administration were discovered in lower baseline HBsAg group (Z=-2.277, P=0.023), HBeAg-seronegative group (Z=-2.200, P=0.028), non-irAEs occurrence group (Z=-2.007, P=0.045) and liver cancer group (Z=-1.987, P=0.047). Of note, 11 patients and 36 patients experienced HBVr (6.11%) and irAEs (20%), respectively, which could lead to discontinuation or delayed use of PD-1 inhibitors. After multivariable analysis, HBeAg-seropositive (OR, 7.236 [95% CI, 1.757-29.793], P=0.01) and the occurrence of irAEs (OR, 4.077 [95% CI, 1.252-13.273], P=0.02) were identified as the independent risk factors for significant HBsAg increase, the occurrence of irAEs (OR, 5.560 [95% CI, 1.252-13.273], P=0.01) was identified as the only independent risk factor for HBVr. PD-1 inhibitors combined with nucleos(t)ide analogues (NAs) may exert therapeutic potential for chronic HBV infection in cancer patients. However, attention also should be paid to the risk of significant elevation in HBsAg levels, HBVr, and irAEs associated with PD-1 inhibitor combinational therapy.

The Clinical Relevance of Fractional Curettage in the Diagnostic Management of Primary Endometrial Cancer

Objective: Hysteroscopy and fractional curettage are commonly utilized techniques for the diagnosis of postmenopausal abnormal uterine bleeding and histopathological verification of primary endometrial cancer (EC). This study delves into the clinical significance of procuring preoperative endocervical tissue in conjunction with corpus fractions through fractional curettage. Design: This retrospective study encompassed a cohort of 84 patients diagnosed with T1 stage EC and 55 patients diagnosed with T2 stage EC, who underwent primary treatment between the years 2011 and 2021 at the University Hospital Frankfurt or Jung-Stilling Hospital Siegen. Materials, Setting, Methods: Among the postoperative T2 stage EC patients, a stratification was performed based on preoperative endocervical curettage (ECC) results obtained through fractional curettage. Categorical and continuous variables were compared utilizing the Pearson χ2 test, while for multivariate analyses and regression modeling, the Kaplan-Meier method and Cox regression models were respectively employed. Results: The median age of patients with pT2 stage EC was 64 years (range: 38–85). A predominant majority of these patients exhibited the endometrioid subtype of EC (90.9%). Upon conducting comparative analysis between groups, a notably higher frequency of laparotomies was observed (p = 0.002) among patients in whom preoperatively detected positive ECC was evident. The detection performance of fractional curettage in identifying positive ECC yielded a sensitivity of 70.9% and a specificity of 73.8%. In multivariate analysis, age at diagnosis (p = 0.022), positive ECC observed during fractional curettage (p = 0.036), and the FIGO stage (p = 0.036) emerged as prognostic determinant for progression-free survival. Independent prognostic factors for overall survival (OS) were age at diagnosis (p = 0.003), positive ECC (p = 0.008), histological grading (p = 0.016), and the FIGO stage (p = 0.022). A significant difference in OS was evident between patients characterized by preoperative negative ECC and those displaying positive ECC (81.8 vs. 59.5 months, p = 0.019). Limitations: Limitations include the retrospective design of the study as well as a small number of patients. Conclusions: Preoperative determination of endocervical involvement of primary T2 stage EC could be a prognostic indicator in decision-making to treat EC. The conduct of prospective trials is necessary to definitively establish the routine application and associated benefits of fractional curettage in the context of primary EC.

Perception and adoption of integrated plant disease management by family farmers in Ribeira Valley (São Paulo State, Brazil)

Family farming, crop diversity and traditional knowledge for plant diseases management characterize Ribeira Valley, São Paulo State, Brazil. Our aim was to diagnose the profile of family farmers from Registro, a municipality of Ribeira Valley, and to determine their perception and adoption of integrated plant disease management (IDM). Semi-structured questionnaire was conducted with farmers and data were analyzed by average, median, mode, Pearson's χ2 test and Monte Carlo simulation. Men and women are involved in farming, but men are prevalent (68%). There are few young people (18% were up to 30 years old), reaffirming their exodus from rural activities. These farmers grow and sell vegetable, fruit, medicinal, and ornamental plants, and they exchange information among themselves, with low demand for farm store sellers. Elimination of symptomatic plants is the main control (13% of strategies adopted). Crop residues elimination, crop rotation and resistant plants were also highlighted (12% each one). Most of the respondents did not know IDM concepts, and after the explanation, they agreed that it is possible put into practice. Dialogue between farmers is strategic for them to obtain information, and rural extension is important for the dialogical transmission of knowledge, and for IDM adoption and maintenance in small properties.

Traqueostomías abiertas y percutáneas en un nivel iii de atención. Estudio de corte transversal

IntroductionThere are 2types of tracheostomy: open (OT) and percutaneous (PT). There is no consensus on the technique of choice for the majority of patients, it is necessary to carry out studies on the clinical results with the use of the 2techniques. ObjectiveCompare the clinical results in patients undergoing OT and PT in the intensive care unit of Hospital Universitario San José, Colombia between 2013 and 2018. MethodsObservational cross-sectional study. A descriptive analysis was made and later both techniques were compared using Pearson's χ2 test for qualitative variables and the Mann-Whitney U test for quantitative ones. ResultsThree hundred and sixty-two patients were included, most underwent PT corresponding to 53.87%. Both groups were similar with respect to clinical and sociodemographic characteristics. The BMI was lower for the TP (P = 0.001). The length of stay in the ICU did not differ, with a median of 19 and 17 for patients with OT and PT, respectively (P = 0.287). Only surgeons performed OT and in PT 35.38% were anesthesiologists, 32.82% surgeons and 32.31% intensivists. The most frequent complication was bleeding, followed by infection, although without a statistically significant difference. Overall mortality of 34.8%, with 0.83% secondary to the procedure. ConclusionsBoth surgeries proved to be safe, with a similar prevalence in terms of complications. PT can be performed by different professionals, without increasing complications. There was a difference in decannulation time, this item should be expanded in future research.

Impact of the COVID-19 pandemic on the demographic and disease burden of pediatric malignant solid tumors in China: a single-center, cross-sectional study.

With the development of the novel coronavirus disease 2019 (COVID-19), China implemented measures in an attempt to control the infection rate. We conducted a single-center, cross-sectional study to ascertain the impact of the COVID-19 pandemic on the equitable availability of medical resources for children diagnosed with malignant solid tumors in China. Data on the demographics, clinical characteristics, and medical expenses of 876 patients diagnosed with neuroblastoma, rhabdomyosarcoma (RMS), Wilms tumor, hepatoblastoma (HB), Ewing sarcoma (ES), and central nervous system (CNS) tumors from 2019 to 2021, during the COVID-19 pandemic, were retrospectively collected from the National Center for Children's Health. The Pearson χ2 test and Mann-Whitney test were performed to analyze the differences among variables. Except for the regional origin of children with tumors during the epidemic, no significant differences were found in the demographic or clinical characteristics of patients at initial diagnosis. The number of patients from northern China and northeastern China who attended Beijing Children's Hospital (BCH) increased after the outbreak of COVID-19 (P=0.001). There was no significant alteration observed in the frequency of hospitalizations per individual per annum (P=0.641) or the mean expense incurred per individual per hospitalization (P=0.361). In addition, the medical insurance coverage rate of real-time settlement increased year by year. After the COVID-19 outbreak, the origin of patients with solid tumor who visited BCH was concentrated in the northern region of China. COVID-19 had no impact on the other demographic factors, clinical characteristics, or economic burden of patients with pediatric malignant solid tumors.

Head and Neck Soft Tissue Sarcoma Patient: Age and Tumor Region Are Predictive in Disease-Free Survival and Overall Survival

Head and neck soft tissue sarcoma (HNSTS), rare and heterogeneous malignancies, are treated primarily treated with surgery. However, prognostic indicators that might guide HNSTS management are poorly defined. Main purpose of this study is to find variables linked to HNSTS patients' prognosis. Assessment of the Tumor, Node, Metastatis (TNM) system is the secondary purpose. This study is a retrospective cohort performed on HNSTS patients who received surgery at the Department of Oral and Maxillofacial Head and Neck Oncology, Shanghai Ninth People's Hospital School of Medicine, Shanghai Jiao Tong University from January 1, 2006, to December 31, 2014. Strict inclusion criteria were applied. The predictor variable was a set of heterogenous risk factors and were grouped into the following categories: demographic (age and gender), clinical (primary tumor, tumor region, tumor size, and TNM stage), and treatment (surgical margin, treatment therapy). The primary outcome variables were time to 5-year disease-free survival (DFS) and 5-year overall survival (OS). The secondary outcome variables were time to 5-year tumor local recurrence and metastasis. Not applicable. Descriptive statistical analysis was carried out. Pearson χ2 test was employed in univariate analysis. Cox regression was modified for multiple variable analysis with components that had significant P values in univariate analysis or variables with potential prognostic value. Log-rank test was applied to compare survival situations under various variables. P value less than .05 was statistically significant. The sample was composed of 100 subjects with a mean age of 43.47 (standard deviation: 16.15) years old and 56 (56%) were male. The 5-year DSF and OS were 59 and 60%, respectively. Variables associated with poor DFS and OS were age > 60years (P=.003, hazard ratio [HR]: 4.95, 95% confidence interval [CI]: 1.71,14.1; P=.005, HR: 4.48, 95% CI: 1.57,12.8) and non-primary tumors (P＜.001, HR: 8.41, 95% CI: 2.85,24.8; P=.002, HR: 6.90, 95% CI: 2.46,19.4), respectively. Maxilla and skull base cancers had local recurrence (12/18, 66.7%) more common. T2 (TNM) tumor displayed higher tendency in DFS(P=.009, HR: 4.20, 95% CI: 1.42,12.4) and metastasis(P=.09, HR: 3.51, 95% CI: 0.82,15.0) than T1 (TNM) tumors. Poor prognosis is associated with maxilla and skull base tumors as well as patients over 60years. TNM stage appeared to have limited prognostic significance.

Which factors affect the lingual fracture pattern in sagittal split ramus osteotomy?

The purpose of this study was to elucidate the effects of mandibular anatomy and osteotomy technique on lingual fracture patterns in SSRO. The predictor variables were: length of horizontal medial osteotomy; type of border osteotomy; buccolingual width; and vertical length of the basal cortex. The outcome variable was the type of lingual split pattern. This was categorized into four types according to a lingual split scale (LSS): LSS 1, true Hunsuck; LSS 2, fracture line to posterior border of the ramus; LSS 3, through to mandibular canal; LSS 4, unfavorable fracture pattern.Data were analyzed using analysis of variance and the Pearson χ2 test. Values of p < 0.05 were considered statistically significant. The study sample comprised 312 lingual split patterns in 156 patients. The most common type of lingual split pattern was LSS 1 (n = 204). There was a significant relationship between inferior border osteotomy type and LSS type (p = 0.001). Whilst LSS 1 was the most common among all border osteotomy types. LSS 4 was most frequently observed in cases where the lower border osteotomy remained in the buccal surface.According to the results of this study, the likelihood of an unfavorable split pattern increases when the lower border osteotomy remains in the buccal surface.

Five-year outcomes for bell bottom, iliac branch endoprosthesis, and coil and cover approaches from the GREAT registry

ObjectiveThere are a variety of methods used today to treat common iliac aneurysms with endovascular techniques. Of these approaches, little is known about whether a particular limb strategy influences endoleak, reintervention, or aneurysm regression rates. We present 5-year data comparing endoleak, stent graft migration, fracture, aneurysm sac dynamics, and aortic rupture rates among patients treated with bell bottom limbs (BB), iliac branch endoprosthesis (IBE), and coil and cover (CC) approaches from the Global Registry for Endovascular Aortic Treatment registry. Secondary end points were all-cause mortality, stroke, reintervention, and paraplegia. MethodsSubjects from the GORE Global Registry for Endovascular Aortic Treatment were enrolled over a 5-year period from October 2017 to August 2022. We included 924 subjects in this study. Statistical data was generated on R software and limb groups were compared using the Pearson's χ2 test and the Kruskal-Wallis rank-sum test. ResultsWe found no statistical difference in endoleak rates, stent graft migration, fracture, or aortic rupture when stratified by limb strategy. There was no difference between limb approaches with regard to aneurysm sac dynamics among those with abdominal aortic aneurysms and common iliac aneurysms. Similarly, no statistical difference between limb strategies was found in all-cause mortality, stroke, paraplegia, or reintervention rates. Among patients that required an additional graft during reintervention, the highest rates were found within the IBE group 8.6%, compared with BB group 2.2% and CC group 1.3% (P = .006). ConclusionsOverall, there was no difference among limb strategies in endoleak rates, stent graft migration, aneurysm sac dynamics, aortic rupture rates, or our secondary end points. Increased rates of reintervention requiring an additional graft within the IBE group is noteworthy and must be weighed against the adverse effects of hypogastric sacrifice with the CC approach or potentially less advantageous seal zones in the BB approach. This finding suggests that all limb approaches have equivalent effectiveness in managing the aneurysmal common iliac artery; thus, the choice of limb strategy should be individualized and remain at physician discretion. Future research should include a more robust sample size to reproduce these findings.

The Effect of Pelvic Floor Muscle Exercises on Bowel Evacuation and Quality of Life in Following Intestinal Ostomy Closure: Randomized Controlled Trial.

This purpose of this study was to evaluate the effect of pelvic floor muscle exercises (PFMEs) on bowel evacuation problems and health-related quality of life (HRQOL) following ostomy closure. Randomized controlled trial. Forty individuals following ostomy closure consented to participate in the study; 6 participants (15%) did not complete the trial (2 died and 2 required a second ostomy) yielding a study sample of 34. Participants were randomly allocated to an Exercise Group (EG, n =17) and Control Group (CG, n =17). The mean age of the EG was 55.7 (SD 12.6) years, whereas the mean age of the CG was 62.0 (SD 12.1) years. The study setting was the surgery clinic of 4 hospitals in Ankara, Turkey. Data were collected between December 2018 and May 2020. The study intervention, PFME training by a clinician, was administered to participants in the EG; CG participants received no information regarding PFME. Data were collected during face-to-face interviews on the day before discharge and by phone at the first, second, third, and sixth months after surgery. A questionnaire was used for data collection that queried a demographic and pertinent clinical questions, along with the Assessment Form for Bowel Evacuation Habits and Psychosocial Problems, Wexner Scale, and the Short Form (SF-36) Health-related Quality of Life Scale. Descriptive statistics and Mann-Whitney U test, t-test, Pearson-χ2 test, Fisher's Exact test, Friedman test, and Cochran-Q test statistical analysis according to normal distribution were used in data evaluation. The number of defecations in the EG was statistically significantly lower than the CG at the second, third, and sixth months (P =.002, P =.002, P =.001, respectively). In addition, the number of individuals experiencing night defecation was statistically significantly less in the EG compared to the CG at the second-, third-, and sixth-month follow-ups (P =.001, P =.001, P =.028, respectively). HRQOL scores were also significantly higher in the EG. Pelvic floor exercises applied after ostomy closure are effective in reducing bowel evacuation and increasing quality of life. Given these findings, PFMEs are recommended for patients after ostomy closure.

The Effect of Cold Saline Irrigation of Dissection Planes in Rhinoplasty on Postoperative Edema and Ecchymosis

Periorbital edema and ecchymosis are frequently encountered after rhinoplasty and may be distressing to patients. Cold therapy is frequently employed in rhinoplasty to reduce postoperative edema and ecchymosis. The aim of this study was to evaluate the effect of cold saline irrigation (CSI) of dissection planes in rhinoplasty on postoperative edema and ecchymosis. The investigators designed a retrospective cohort study. The data of patients who underwent rhinoplasty in our clinic between January 2021 and January 2023 were scanned. Patients who underwent primary open rhinoplasty from the same surgeon and standard rhinoplasty steps were applied in the same way and order were included in the study. Patients who had systemic diseases and previous nose surgery, and patients whose photographs could not be accessed from the photograph archive were excluded. According to whether CSI was applied to the dissection plans during rhinoplasty, the patients were divided into the CSI group and the control group (without CSI). Patients' grades of periorbital edema and ecchymosis were the main outcome variables. The differences of outcome variables were compared between the 2 groups. Demographics (age, sex), and surgical detail (duration of surgery) were collected as covariates. The numerical variables were compared between the two groups using the student's t-test and Mann-Whitney U test, whereas the categorical variables were compared using Pearson's χ2 and Fisher's exact tests. P<.05 was considered statistically significant. Among the 167 patients who met the inclusion criteria, 60 patients were randomly selected, 30 patients in each group. No statistically significant difference was found between the two groups in terms of age (P=.45) and sex (P=.27). The mean ecchymosis grade was statistically significant lower in the CSI group than in the control group for all evaluation times (P<.05). Similarly, the mean edema grade was statistically significant lower in the CSI group than in the control group for all evaluation times, with the exception of the 10th and 15th day (P<.05). CSI of the dissection planes in rhinoplasty reduced the development of periorbital edema and ecchymosis. This procedure is straightforward, inexpensive, and effective.
