Effect of body mass index on post-treatment oral function in patients with oral cancer: a cross-sectional study

This single-center cross-sectional study used sequential sampling to examine the influence of body mass index (BMI) on oral function after oral cancer treatment. Patients who completed primary oral cancer treatment between September 2019 and March 2023 (102 patients, 74 male [72.5%] and 28 female [27.5%]; mean age, 69.6 years) were analyzed. Patient background data were collected from electronic medical records. Post-treatment oral function measurements were conducted on all patients using six assessment tools. Statistical analysis was conducted using Pearson’s correlation coefficient, one-way analysis of variance, the Jonckheere–Terpstra test, and multiple linear regression. Pre-treatment BMI showed a statistically significant relationship with postoperative oral function, particularly tongue pressure (P = 0.01). While the mean values of the groups showed no significant differences, the Jonckheere–Terpstra test revealed a statistically significant trend toward a stepwise increase in tongue pressure for each BMI group (P = 0.03). Multiple linear regression analysis revealed a statistically significant correlation between tongue pressure and pre-treatment BMI (P < 0.05). Pre-treatment BMI was significantly associated with tongue pressure. Since BMI is a variable factor that can be controlled by nutritional therapy even before treatment, nutritional intervention, weight control, and treatment strategies including reconstructive interventions to maintain tongue pressure may be important in oral cancer treatment.

No single safe zone exists for the valgus cut angle to reproduce neutral mechanical alignment in the presence of femoral bowing in total knee arthroplasty.

The aim of this study is to report the prevalence of femoral bowing in the Egyptian arthritic knees as a representative of the middle eastern population and to study the correlation between the femoral bowing and the degree of arthritis, varus deformity and the distal femoral valgus cut angle (VCA). This is a single-center observational cross-sectional study. Out of 562 knees Scheduled for TKA, 124 knees were excluded leaving 438 knees eligible for the study. The following angles were measured by two independent orthopedic surgeons: Femoral bowing angle (FBA), HKA angle, LDFA, MPTA and VCA. Out of 438 knees, 21knees (4.8%) had medial bowing (< - 3°), 111 (25.3%) had normal bowing (+ 3° to - 3°) and 306 (69.9%) had LFB of which 111 (25.34%) had mild LFB (+ 3 to + 5°) and 195 (44.52%) had severe LFB (> + 5°) bowing. LFB was more in older age group (p = 0.005), in females (p < 0.001), and in grade 4 OA, (p < 0.001). Also, there was a significant positive correlation between FBA and age and increasing varus HKA, and with varus orientation of the distal femur and the tibial plateau. The mean and the 95% confidence interval of the VCA for the medial bowing group was 3.43 (3.01-3.85°), for the normal bowing group was 5.42 (5.15-5.68°), for the mild lateral bowing was 6.74 (6.47-7°), and for the severe bowing group was 9.23 (8.89-9.55°). There is no single safe zone for the VCA to reproduce postoperative neutral coronal alignment especially in cases of severe lateral femoral bowing in TKA. However, the VCA should be analyzed in term of how much femoral bowing exists. In other words, for each subset of femoral bowing there is a safe zone for the VCA.

Prevalence and predictors of polypharmacy and comorbidities among patients with chronic obstructive pulmonary disease: a cross-sectional retrospective study in a tertiary hospital in Saudi Arabia

ObjectiveThis study aimed to determine the prevalence of polypharmacy, comorbidities and to investigate factors associated with polypharmacy among adult patients with Chronic Obstructive Pulmonary Disease (COPD).MethodsThis was a retrospective single-centre cross-sectional study. Patients with a confirmed diagnosis of COPD according to the GOLD guidelines between 28 February 2020 and 1 March 2023 were included in this study. Patients were excluded if a pre-emptive diagnosis of COPD was made clinically without spirometry evidence of fixed airflow limitation. Population characteristics were presented as frequency for categorical variable. Logistic regression analysis was used to identify predictors of polypharmacy.ResultsThe study sample included a total of 705 patients with COPD. Most of the study sample were males (60%). The mean age of the study population was 65 years old. The majority of the study population had comorbid diseases (68%), hypertension and diabetes were the most common co-existent diseases. Around 55% of the study sample had polypharmacy. Females were significantly less likely to be on polypharmacy compared to males (OR = 0.68, 95% CI = [0.50–0.92], P-value = 0.012)). On the other hand, older patients aged 65.4 or more (OR = 2.31, 95% CI = [1.71–3.14], P-value ≤ 0.001), those with high BMI (≥ 29.2) (OR = 1.42, 95% CI = [1.05–1.92], P-value = 0.024), current smokers (OR = 1.9, 95% CI = [1.39–2.62], P-value ≤ 0.001), those who are receiving home care (OR = 5.29, 95% CI = [2.46–11.37], P-value ≤ 0.001), those who have comorbidities (OR = 19.74, 95% CI = [12.70–30.68], P-value ≤ 0.001) were significantly more likely to be on polypharmacy (p ≤ 0.05).ConclusionsPolypharmacy is common among patients with COPD. Patients with high BMI, previous ICU hospitalization and older age are more likely to have polypharmacy. Future analytical studies are warranted to investigate outcomes in patients with COPD and polypharmacy.

Can pre-analytical procedures improve microbiological culture yield in patients with periprosthetic infections?

BackgroundThe detection of causative pathogens plays a crucial role in the diagnosis and targeted treatment of periprosthetic joint infections (PJI). While there have been improvements in analytic methods in the past, pre-analytical procedures have not yet been sufficiently investigated. The objective of this study was to compare the culture yield of four different pre-analytical procedures.MethodsPatients with perioperative diagnosis of PJI were included in a single center cross-sectional study (2021–2022). Tissue samples (n = 20) of each patient were randomly and equally distributed to each of the four study arms. Tissue samples were either send to the laboratory without culture medium (group A) or were transported in thioglycolate medium immediately after sampling at three different temperatures (room temperature, 4 °C, 37° for 24 h; group B-D). Culture media were investigated for growth on days 1, 3, 7, 12, 14. All organisms, the number of positive samples and the time to positivity were recorded and compared between the study arms. Single positive cultures were considered as contamination.ResultsIn total, 71 patients were included. The proportions of culture negative samples (10–15%) and polymicrobial infections (51–54%) were comparable between the four arms. Seven patients (10%) were culture-negative in group A, but showed growth in thioglycolate media (group B-D). Furthermore, 13% of patients showed growth in all groups, but additional organisms were cultured in thioglycolate. There was growth beyond day 7 of culturing only in thioglycolate, but not in group A. A storage temperature of 4 °C showed a longer time to positivity compared to the other groups (p < 0.001).ConclusionsPre-analytical storage of tissue samples in thioglycolate broth did not improve the culture yield and did not detect additional cases of infection compared to the standard (pre-analytical storage in sterile containers). However, including a thioglycolate medium to the sampling algorithm reduced the rate of culture-negative infections and helped to identify additional organisms.

Is Arterial Stiffness Interconnected with Cardiovascular Drug Prescription Patterns, Body Composition Parameters, and the Quality of Blood Pressure Regulation in Hypertensive Patients?

Background: Arterial hypertension (AH) is a significant risk factor for cardiovascular disease and is associated with increased arterial stiffness, particularly as measured by pulse wave velocity (PWV). This study aims to explore the relationships between age groups, antihypertensive and new oral antidiabetic drugs, body composition, and arterial stiffness parameters in hypertensive patients. Methods: A single-center cross-sectional study was conducted including 584 participants who underwent 24 h ambulatory blood pressure monitoring (including central blood pressure (BP) and PWV measurement), body composition analysis, and provided medical history and current pharmacotherapy data. Results: The study found that PWV was significantly higher in patients with poorly regulated BP in those aged 65 years and older. Significant PWV predictors included systolic BP, heart rate, peripheral mean arterial pressure, peripheral pulse pressure, augmentation index, calcium channel blockers, moxonidine, sodium–glucose co-transporter 2 inhibitors, urapidil, and statin prescription. Also, statistically significant negative correlations were found between PWV and visceral fat level, fat-free mass, and the percentage of muscle mass. Conclusions: The findings suggest that arterial stiffness is interconnected with peripheral and central blood pressure parameters, body composition parameters, and prescribed hypertensive and new antidiabetic drugs.

Sleep disruption in patients with active and treated endogenous Cushing's syndrome.

The hypothalamic-pituitary-adrenal axis is a critical regulator of circadian rhythm in humans. Impaired sleep adversely affects metabolic, emotional, and cognitive health. To characterize sleep disturbances in patients with active and treated Cushing's syndrome (CS), and identify factors associated with impaired sleep in treated patients. Single-center cross-sectional study. Patients with pituitary or adrenal CS enrolled in an observational study completed Nottingham Health Profile (NHP), CushingQoL, and Hospital Anxiety and Depression assessments. Cross-sectional analysis was conducted including patients with active and treated disease. 113 (94 female) patients with CS were included, 104 pituitary and 9 adrenal, with mean age at diagnosis of 43.9 ± 13.4 years. Mean and maximum duration of follow up was 5.1 and 23 years. Mean NHP sleep score was lower (i.e., improved) in patients with treated vs. active disease (29.6 ± 30.2 vs. 51.9 ± 30.9, p = 0.0005), as was CushingQoL sleep score (p = 0.015), but 41.5% of patients with treated disease stated they often or always had trouble sleeping. The proportion of treated vs. active patients taking medication for sleep, mood, or pain was not different. Neither NHP nor CushingQoL pain scores were lower in treated vs. active patients (p = 0.39 and 0.53). In patients with treated CS, anxiety and depression correlated with worse sleep scores. Patients with treated CS report improved sleep quality compared to those with active disease, but almost half of treated patients still report sleep challenges. The need for sleep medications, reported by one third of patients, was not different after CS treatment. Ongoing mood disturbances may play a role in persistent sleep disruption. Further work should focus on determinants of sleep impairments in treated CS patients.

The simultaneous presence of active BK, Epstein Barr, and human cytomegalovirus infection and their correlation by host factors in patients suspected of kidney transplant rejection

AimsThis study aims to evaluate the presence of EBV, HCMV, and BKV genomic sequences in the plasma samples (active infection/viremia) of kidney transplant recipients suspected of rejection and to investigate host and risk factors related to the activation of these viruses in these patients.MethodsIn this cross-sectional single-center study, plasma samples were collected from 98 suspected kidney transplant rejection patients at Labafinejad Hospital, Tehran, Iran, between December 2022 and June 2023. Quantitative real-time PCR assays for HCMV, EBV, and BK were performed using GeneProof Real-time PCR kits. ROC curve analysis was used to determine the viral load cutoff point for each virus.FindingsHCMV active viremia was detected in 18 (18.36%) recipients, EBV active viremia in 7 (7.14%), and BKV active viremia in 5 (5.10%). ROC results indicated viral load cutoff points of 778, 661, and 457 points for HCMV, EBV, and BKV, respectively. The duration of time after transplantation significantly differed between active viremia and no viremia groups (120.5 vs. 46 months, P = 0.014). In the BKV active viremia group, the increase in creatinine compared to baseline creatinine was significantly higher than in the no viremia group (2.7 vs. 0.8, P = 0.017). The odds ratio of HCMV active viremia in patients taking tacrolimus was 2.84 times higher, and the odds of HCMV active viremia in patients taking antithymocyte globulin was 3.01 times higher than in patients not taking these drugs.ConclusionRapid and timely diagnosis of viral active infections in kidney transplant patients is crucial for effective disease management and implementation of appropriate treatment strategies. Identifying potential risk factors, including host and treatment-related factors that influence transplantation, can facilitate the development of suitable preventive strategies.

Emergency department service utilisation of older patients with urgent conditions: a cross-sectional observational study

BackgroundAs with many countries worldwide, Singapore is experiencing a rapidly ageing population. Presentation of older persons for urgent but non-emergent conditions to the Emergency Department (ED) represents a growing group of patients utilising public healthcare emergency services and puts a strain on current ED resources. The medical conditions vary, and resources used has been poorly characterized.MethodsThis is a single-center cross-sectional observational study of patients aged 55 to 75 years old who visited the ED with urgent conditions, Patient Acuity Category Scale (PACS) P2 or P3, who were subsequently discharged. The patients visited a public hospital in Singapore on four randomly selected weekdays in April 2023. The utilisation of hospital resources and manpower was studied. A formulated criteria was used to determine the appropriate site of care, such as an Urgent Care Centre (UCC), Primary Care Providers (PCP) clinic or the ED.ResultsThere were 235 eligible patients during the study period, with a mean age of 65.1 years of which a majority, 183 (77.9%) were allocated to patient acuity category scale P2. Most of the patients were walk-in patients with no referrals (169 (71.9%)). Based on the criteria, the majority of 187 (79.6%) of these patient may be safely managed at an outpatient setting; 71 (30.2%) patients by PCP, 116 (49.4%) patients may be managed by an UCC, with the remaining 48 (20.4%) requiring ED care.ConclusionOur findings indicate that a significant portion of discharged older ED adults with urgent but non-emergent conditions may be adequately managed at outpatient medical services that are appropriately resourced. More research is needed on healthcare initiatives aimed at developing the capabilities of outpatient medical services to manage mild to moderate acute conditions to optimise ED resource allocation.

Evaluation of serum vitamin B12 and D, iron, ferritin, folate, calcium, phosphorus and magnesium levels in children in palliative care clinic: a single-center cross-sectional study

BackgroundPediatric palliative care (PPC) patients are at an elevated risk of malnutrition. Nutritional inadequacy can also cause micronutrient deficiencies. These factors can lead to weight loss, stunted growth, and poor quality of life. Despite the prevalence of these issues, limited research exists in the micronutrient status of PPC patients. The purpose of this study was to determine the vitamin B12 and D, iron, ferritin, folate, calcium, phosphorus, and magnesium levels of PPC patients to contribute to a better understanding of their micronutrient needs as well as the appropriate management of diet and treatment approaches.MethodsThis was a single-center observational cross-sectional retrospective study. This study evaluated the levels of vitamin B12, 25-hydroxyvitamin D, iron, ferritin, folate, calcium, phosphorus, and magnesium in PPC patients. The patients were classified according to the Chronic Complex Conditions (CCC) v2 and then compared.ResultsA total of 3,144 micronutrient data points were collected from 822 hospitalizations of 364 patients. At least one micronutrient deficiency was identified in 96.9% of the patients. The most prevalent deficiencies were observed for iron, calcium, and phosphate. In addition, 25-hydroxyvitamin D deficiency was observed in one-third of patients. Calcium, magnesium, phosphorus, folate, and 25-hydroxyvitamin D were negatively correlated with age.ConclusionThe results of this study indicate that micronutrient deficiencies are highly prevalent in PPC patients. These findings have the potential to contribute to improvements in the nutritional and therapeutic management of patients.

Barriers to adherence to secondary prevention therapy in patients with ischemic heart disease: a cross-sectional study of a Mexican reference center.

This article aims to assess the adherence level to second-line therapy for cardiovascular prevention in a tertiary hospital in Mexico City and identify key barriers to adequate pharmacological adherence. A single-center prospective cross-sectional study was conducted between August 2018 and February 2020. Sociodemographic data were collected, and the Morisky medication adherence scale was performed. Directed interviews during medical consultations were also conducted to determine reasons for non-adherence. Showed that out of 991 patients included with a median age of 65 (58.72) years, 70.3% exhibited inadequate adherence, with forgetfulness being the most common reason (55.4%). Patients receiving combined therapy with coronary revascularization showed higher adherence compared to those on optimal medical therapy alone. Low educational level (OR 1.68, IC 95% 1.23-2.23, p = 0.0001) and the use of optimal medical therapy alone (OR 1.2, I 95% 1.11-2.007 p = 0.007) were identified as predictors of poor adherence. Among patients with ischemic heart disease and pharmacological therapy for secondary prevention, inadequate adherence is observed in 70% of cases. Factors associated with poor pharmacological adherence were low educational level and prescription of medical therapy without revascularization.

Knowledge and perception among adults of their congenital heart disease: A single center cross-sectional study

Introduction and objective: Congenital heart disease (CHD) is a complex condition requiring a multidisciplinary approach. It is crucial that adults with CHD (CHD) have adequate knowledge of their condition, enabling them to engage in their healthcare decisions and self-management. We aimed to investigate knowledge and perception among adults of their CHD.Methods: Single-center, observational, cross-sectional study. A 25-item adapted survey of Leuven Questionnaire for CHD was used to assess four main domains: (1) disease and treatment, (2) endocarditis and preventive measures, (3) physical activity and (4) reproductive issues.Results: 148 patients participated in the study. Patients had a significant lack of knowledge localizing their heart defect, recognizing drug side effects, acting in case of experiencing drug side effects, recognizing at least two symptoms of clinical deterioration, to adequately define endocarditis and most typical signs and risk factors, to acknowledge the hereditary nature of their CHD and risk of clinical deterioration during pregnancies. Patients with an education level ≥12th grade have higher knowledge in various items and, overall, the complexity of CHD was not associated with a better performance.Conclusion: This study highlights the existing knowledge gaps among adults with CHD. It underscores the need for tailored information and structured educational programs to improve management. By addressing these challenges, healthcare providers can enhance patient outcomes, improve quality of life, and promote long-term well-being for individuals with CHD.

Factors associated with pseudoparalysis in patients with extensive chronic and atraumatic rotator cuff injury

BackgroundPatients with massive chronic atraumatic rotator cuff injuries can be asymptomatic or present severe shoulder dysfunction, a condition known as pseudoparalysis. Our hypothesis is that integrity of the subscapularis, hypertrophy of the Teres minor, and a complete tear of the long head of the biceps tendon are associated with improved active forward flexion range in such patients. Therefore, the objective of this study was to evaluate factors associated with pseudoparalysis. MethodsThis was a single-center cross-sectional study that included patients with massive chronic atraumatic rotator cuff injuries. Range of motion of the affected shoulder, demographic data, specific tests for rotator cuff assessment, and imaging studies were collected. ResultsA total of 68 patients (71 shoulders) were included in the study. At initial evaluation, 41 patients exhibited active forward flexion of the shoulder greater than 90º (No Pseudoparalysis group). Patients with active forward flexion less than 90º (n = 29) underwent subacromial injection of local anesthetic and were then reevaluated. In 15 patients the pseudoparalysis was resolved (False Pseudoparalysis group) and 14 maintained active forward flexion of less than 90° (True Pseudoparalysis group). ConclusionWe concluded that the presence of shoulder shrug sign, Goutallier grade III and IV fatty infiltration and a full-thickness tear of the subscapularis were risk factors for the occurrence of pseudoparalysis. Tear extension, as described by Wieser et al, also demonstrated statistical difference between groups, with greater anterior tear extension (involvement of subscapularis tendon) and greater global tear extension observed in True Pseudoparalysis group.

Behavioral Problems and Self-Feeding Independence Among Patients With Acute Stroke: A Single-Center Study.

Self-feeding independence is often the first goal in acute stroke rehabilitation. Attention deficits appear frequently after stroke, but neuropsychological tests may be difficult to perform in the acute phase, and the effect on self-feeding activities may be difficult to detect. Therefore, we aimed to clarify behavioral problems with self-feeding using the Moss Attention Rating Scale (MARS), a behavioral observational rating scale of attentional function, for a better understanding of the effects of self-feeding. To identify behavioral problems caused by attention deficits among patients with acute stroke who need assistance in self-feeding, using the MARS. Cross-sectional single-center study. St. Marianna University Yokohama Seibu Hospital, Kanagawa, Japan. A total of 96 patients (42 women and 54 men) were admitted to the hospital for stroke treatment. Patients' median age was 75.0 yr. The date of evaluation was a median of 3.0 days from admission. The primary outcome was the FIM® eating subscore. The secondary outcome was the MARS score. Significant differences were noted in the total raw MARS, logit, and three-factor scores for self-feeding independence (p < .01). The effect size of the consistent or sustained factor on independence was large (r = .83). Behavioral problems related to self-feeding dependence include the inability for sustained attention. Our results suggest that sustained concentration during self-feeding is necessary for eating independence. Rehabilitation focused on sustained attention is important for independent self-feeding. Plain-Language Summary: A patient's self-feeding independence is often the first goal in acute stroke rehabilitation. Patients frequently experience attention deficits after a stroke, but neuropsychological tests may be difficult to perform in the acute phase of rehabilitation, and the effect of attention deficits on self-feeding may be difficult to identify. To have a better understanding of the effects on self-feeding, this study aimed to identify behavioral problems using the Moss Attention Rating Scale (MARS). The study found that the MARS can be used to identify behavioral problems related to self-feeding independence, which can help occupational therapists to develop rehabilitation programs for their clients who have experienced a stroke.

ESKAPE Pathogens: Antimicrobial Resistance Patterns, Risk Factors, and Outcomes a Retrospective Cross-Sectional Study of Hospitalized Patients in Palestine.

Antimicrobial resistance to ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp). remains a major challenge in hospital settings. This study aimed to determine the ESKAPE antimicrobial resistance patterns and associated factors with multi-drug resistance strains among hospitalized patients in a single tertiary care medical hospital in Palestine. A single-center retrospective cross-sectional study was conducted by reviewing patients' electronic medical records and laboratory results from November 1, 2021, to November 30, 2022, at the Palestine Medical Complex in Palestine. The study included patients aged > 18 years who had been infected with ESKAPE pathogens 48 hours after hospital admission. This study included 231 patients, of whom 90.5% had MDR infections. In total, 331 clinical samples of ESKAPE pathogens were identified. A. baumannii was the most prevalent MDR pathogen (95.6%) with Carbapenem-resistant exceeding 95%, followed by K. pneumoniae (83.8%) with extended-spectrum cephalosporin resistance exceeding 90%, S. aureus (68.2) with 85% oxacillin-resistance, E. faecium (40%) with 20% vancomycin resistance, P. aeruginosa (22.6%) with 30% carbapenem resistance. Furthermore, emergent colistin resistance has been observed in A. baumannii, K. pneumoniae, and P. aerogenesis. Risk factors for MDR infection included age (p< 0.035), department (p< 0.001), and invasive procedures such as IUC (p< 0.001), CVC (p< 0.000), and MV (p< 0.008). Patients diagnosed with MDR bacteria had increased 30-day mortality (p< 0.001). The findings of this study show alarming MDR among hospitalized patients infected with ESKAPE pathogens, with resistance to first-line antimicrobial agents and emerging resistance to colistin, minimizing treatment options. Healthcare providers and the Ministry of Health must take steps, adopt policies to prevent antimicrobial resistance, adhere to infection control guidelines, implement antimicrobial stewardship programs to prevent and limit the growing health crisis, and support research to discover new treatment options.

Role of quantitative planar lung perfusion scintigraphy and tomography in identifying target lobes in patients with emphysematous phenotype of advanced chronic obstructive pulmonary disease: a retrospective cross-sectional study.

Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease. Despite optimal medical therapy and pulmonary rehabilitation, bronchoscopic and surgical lung volume reduction may still be necessary. Identifying the target lobe is crucial for the success of these treatments. This study aims to compare the role of quantitative planar lung perfusion scintigraphy (QPLPS) with quantitative lung computed tomography (StratX®), which is used in identifying the target lobe before the Zephyr® endobronchial valve (EBV) placement in patients with the emphysematous phenotype of advanced COPD. A single-center retrospective cross-sectional study was performed in the Department of Pulmonology at the University of Health Sciences Turkey, Yedikule Chest Diseases and Thoracic Surgery Education and Research Hospital between June 2019 and June 2022. The study included 46 patients with the emphysematous phenotype of advanced COPD, who were all candidates for Zephyr® EBV therapy. The target lobes were assessed using the QPLPS and StratX® and the agreement between the methods was analyzed by the Kappa statistic method. Additionally, demographic characteristics, respiratory function tests, distributions of emphysema, and 6-minute walk test results of patients were recorded. The median age was 67 (42-80) years and 42 (91.3%) were male. In QPLPS, the perfusion percentages were 7.47%±3.31%, 9.59%±2.67%, and 13.32%±2.59% for the 1st, 2nd and 3rd target lobes, respectively while in StratX®, the voxel densities were 68.28%±9.16%, 63.79%±7.42%, and 60.69%±5.35%. In StratX®, the fissure integrity (FI) at the target lobe was 76.25%±21.18%, 84.68%±17.67%, and 86.19%±13.19%, respectively. There was a significant agreement between the methods in identifying the first, second, and third target lobes in all patients (Kappa coefficient: 0.897, 0.700, and 0.522), and also in identifying the first and second target lobes in patients with heterogeneous (Kappa coefficient: 0.879, and 0.735), and homogeneous subgroups (Kappa coefficient: 0.919, and 0.672). There is an agreement between QPLPS and StratX® in identifying the target lobe in patients with severe emphysema, including those with homogeneous diseases. However, StratX® may be preferred, considering that it also predicts FI.

Factors Associated with Vaccination Adequacy in People Living with HIV: A Cross-Sectional Study

People living with HIV (PLHIV) are at greater risk of illness and death from vaccine-preventable diseases. This study aimed to identify the predictors associated with the recommended vaccination schedule for this group. This was a single-center cross-sectional study conducted in a large Brazilian municipality, evaluating the vaccination statuses of 645 PLHIV for nine immunizers. The primary outcome was the adequacy of the vaccination schedule. The vaccination status was assessed for the diphtheria/tetanus, hepatitis B, hepatitis A, measles/mumps/rubella, yellow fever, 13- and 23-valent pneumococcal, meningococcal C, and HPV vaccines. Those who had received all of the recommended vaccinations in accordance with the schedule established by the government at the time of the assessment, without any delays, were classified as having received an “adequate schedule”. The independent variables included sociodemographic, clinical–epidemiological, and social vulnerability factors, analyzed by multiple logistic regression with adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). Only 47 individuals (7.3%) had an adequate vaccination schedule for all vaccines. The vaccines with the highest adequacy rate were diphtheria and tetanus (533; 82.6%), and the one with the lowest rate was measles/mumps/rubella (MMR) (243; 37.7%). The main predictors of a complete vaccination schedule were the age group, place of clinical follow-up, and where they received their last doses of vaccines. Educational interventions for PLHIV and health professionals are needed to improve the vaccination coverage in this group.

Ultra-processed foods consumption is positively associated with the clinical activity of inflammatory bowel diseases - a cross sectional single center study

Introduction: Western diet pattern and its food components have been suggested to impact inflammatory bowel diseases (IBD) clinical course. However, the importance of food processing level is uncertain. We aimed to evaluate whether the intake of foods with varying processing levels is associated with disease activity in IBD patients. Methods: This cross-sectional study was performed at a tertiary center between August 2019 to June 2022. Consecutive adult IBD patients were recruited. Clinical disease activity was defined using HBI (Crohn's disease) and SCCAI (ulcerative colitis). Dietary intake was assessed using a food frequency questionnaire (FFQ) and a dedicated validated processed food questionnaire (PFQ) that categorizes dietary intake into three groups of processed food levels: unprocessed/minimally processed, processed, and ultra-processed. Adjusted odds ratios for active disease were determined using a multivariable logistic regression. Results: A total of 242 IBD patients (62.8% Crohn’s disease patients) were enrolled, of whom 73.1% were in clinical remission. A higher (upper tertile vs. lowest tertile) unprocessed/minimally processed foods consumption was negatively associated with active disease (OR=0.38, 95%CI 0.14-0.99), while high consumption of ultra-processed foods (UPFs) was positively associated with clinically active disease (OR=3.82, 95%CI 1.49-9.8). Consumption of UPF groups, almost invariably, were positively associated with clinically active disease, while consumption of the ultra-processed meats group, had the strongest association (OR=4.45, 95%CI 2.07-9.79). Conclusion: Higher consumption of UPFs is positively associated with clinically active IBD, while higher consumption of unprocessed/minimally processed foods may be protective. Prospective studies are needed to confirm these associations.

Paediatric maxillofacial fractures have increased in incidence and their nature and aetiology have changed during three decades

The safety of children’s living environment is affected by several factors. Safer living environments have been offered as one explanation to decreases in children’s fractures. Earlier studies provide evidence of a decreasing trend in children’s fractures in the past decades. The objective of this study was to investigate demographic and clinical features of paediatric maxillofacial fractures during three time periods. A retrospective cross-sectional single-centre study was designed. The study included 474 patients aged ≤ 15 years admitted to Helsinki University Hospital in Finland with maxillofacial fractures during 1980–1989, 1993–2002 and 2013–2018. Maxillofacial fractures increased by 25% during the study period. The increase was greater in boys (28%) than in girls (19%), and significant in age groups 0–5 years (71%) and 13–15 years (32%). Exclusively mandibular fractures decreased by 20%, while exclusively midfacial fractures increased more than four-fold and exclusively upper-third fractures five-fold. Being hit by object and falls from height increased more than two-fold. A temporary increase in assaults and decrease in bicycle accidents in the middle period of the study was observed. During the three decades, paediatric maxillofacial fractures have increased and both fracture type and underlying aetiology have changed. These findings reflect improvements in diagnostics, traffic safety, regulations and technology. The role of factors such as interpersonal violence and economic fluctuation on the incidence of childhood maxillofacial fractures is discussed.

Association between serum remnant cholesterol level and metabolic dysfunction-associated steatotic liver histology.

Estimated remnant cholesterol (Rem-C) level, a risk factor for cardiovascular disease (CVD), is associated with metabolic dysfunction-associated steatotic liver disease (MASLD) diagnosed via ultrasonography. However, the relationship between accurate serum Rem-C level measurements and histological findings of MASLD remains unclear. We aimed to elucidate the relationship between accurately measured serum Rem-C levels and histological findings of MASLD. Cross-sectional single-center observational study. We assessed 222 patients (94 men and 128 women; age 20-80) who were diagnosed with MASLD via liver biopsy with available medical history, physical examination, and biochemical measurement data. Serum ester-type cholesterol and free cholesterol contents in the remnant lipoproteins were measured using an enzymatic method. Serum Rem-C levels were significantly higher in patients with NAFLD activity score (NAS) 5-8, ＞66% steatosis grade, lobular inflammation with ≥5 foci, and many cells/prominent ballooning cells (a contiguous patch of hepatocytes showing prominent ballooning injury) than in patients with NAS 1-4, <33% steatosis grade, lobular inflammation with <2 foci, and few ballooning cells (several scattered balloon cells), respectively. While univariate analysis revealed no significant association between Rem-C levels and advanced fibrosis, a significant association between Rem-C levels and NAS was evident. This relationship remained significant in multivariate analysis adjusted for confounders. Furthermore, in the analysis by sex, these relationships were significant for men but not for women. High serum Rem-C levels were associated with high NAS, but not with fibrosis stage, particularly in men. Controlling serum Rem-C level may improve MASLD activity.

Correlation between non-alcoholic fatty liver disease and metabolic parameters in persons with newly diagnosed type 2 diabetes mellitus.

There are limited studies investigating the association between type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease (NAFLD) in the region of Bihar, India. To estimate the prevalence of NAFLD in persons with newly diagnosed T2DM in the population of North Bihar, India. This single centre cross-sectional study was undertaken in the Research Centre for Diabetes Hypertension and Obesity, Samastipur, Bihar, India. Data were collected from persons newly diagnosed with T2DM or those diagnosed within 6 months of when the study was conducted between December 2022 to May 2023. A total of 148 people with newly diagnosed T2DM were included (median age 47 years, 46.6% female) and 109 patients with liver disease on ultrasound evaluation. The persons with liver disease consumed more fats and oils (88.1% vs 74.4%, P = 0.042) and they had significantly greater body mass index (27.4 vs 23.0, P < 0.001), waist circumference (37 vs 33, P < 0.001), and waist-to-hip ratio (1.00 vs 0.70, P = 0.025). Females were associated with greater liver disease [odds ratio (OR): 3.09, 95% confidence interval (CI): 1.09-8.80, P = 0.32]. Waist circumference (OR: 1.42, 95%CI: 1.22-1.66, P < 0.001) and low-density lipoprotein cholesterol (OR: 1.01, 95%CI: 1.01-1.02, P = 0.048) were associated with any liver disease. The factors most associated with grade 2/3 liver disease was right upper quadrant pain or heaviness (OR: 5.22, 95%CI: 1.40-19.41, P = 0.14), greater income (OR: 3.58, 95%CI: 1.28-10.04, P = 0.015) and waist circumference (OR: 1.31, 95%CI: 1.02-1.69, P = 0.036). NAFLD is common in new/recently diagnosed T2DM and disease burden is high and common among patients who are either high consumers of fats and oils or have obesity-associated markers.
