ABSTRACT

BACKGROUND: To investigate the antibiotic resistance of Helicobacter pylori (H. pylori) strains to clarithromycin, metronidazole, amoxicillin, levofloxacin, furazolidone, and tetracycline in Chinese children.

MATERIALS AND METHODS: This multicenter, retrospective study was conducted from January 2016 through May 2023. Gastric mucosa biopsies were obtained from pediatric participants who underwent upper gastrointestinal endoscopy at 96 hospitals in northern, southwestern, and southeastern China. The susceptibility of H. pylori to six commonly used antibiotics was determined by agar dilution method.

RESULTS: Among the 3074 H. pylori isolates, 36.7% were resistant to clarithromycin, 77.3% to metronidazole, 16.6% to levofloxacin, and 0.3% to amoxicillin. No strains were detected to be resistant to furazolidone or tetracycline. During the 8-year study period, resistance to clarithromycin and metronidazole showed a significant upward trend, while the resistance pattern of the other antibiotics demonstrated a slight but nonsignificant fluctuation. Significant regional differences were found in the distribution of clarithromycin resistance among the northern (66.0%), southwestern (48.2%), and southeastern (34.6%) regions. The metronidazole resistance rate was significantly lower in the southeastern coastal region (76.3%) than in the other two regions (88.2% in the north and 87.7% in the southwest). Multi-drug resistance for two or more antibiotics was detected in 36.3% of the H. pylori strains, and the predominant multi-resistance pattern was the dual resistance to clarithromycin and metronidazole.

CONCLUSIONS: The prevalence of H. pylori resistance to clarithromycin and metronidazole is rather high in Chinese children and has been increasing over time. A relatively high resistance rate to levofloxacin was also noticed in children, while almost all strains were susceptible to amoxicillin, furazolidone, and tetracycline. It will be of great clinical significance to continuously monitor the antibiotic-resistance patterns of H. pylori in the pediatric population.

ABSTRACT

BACKGROUND: Temporomandibular disorders are the most common condition affecting the orofacial region, resulting in pain and dysfunction.

OBJECTIVE: This study aimed to elucidate the ambiguous association between cervical features and temporomandibular disorders by measuring the rotations between the skull-atlas, atlas-axis and mandible-atlas and examining the relationship between these rotations and temporomandibular disorders.

METHODS: Cone-beam computed tomography (CBCT) images from 176 patients, 97 females and 79 males with an average age of 25.7 years were used in this study. The patients were divided into two groups: those with joint dysfunction (n = 88) and those without (n = 88). The study employed various methods to determine rotations in the skull-atlas, atlas-axis and mandible atlas based on anatomical landmarks and measurements. These methods include the use of specific planes, angles and distances to identify and measure rotation. Data analysis was performed using the TURCOSA statistical software (Turcosa Analytics Ltd Co, Turkey, www.turcosa.com.tr).

RESULTS: The results showed that the degree of rotation between the skull and the atlas was higher in the TMD group than in the control group (p < .001). Similarly, Atlas-axis rotation was significantly higher in the TMD group (p < .001). However, no significant difference was found between mandible atlas rotations in the two groups (p = .546). The study also found a significant difference between the direction of rotation between the atlas and axis and the direction of mandible atlas rotation (p < .001) as well as between skull and atlas rotations and mandible-atlas rotations (p < .001).

CONCLUSION: Overall, the study suggests that there is a relationship between the skeletal structures of the cranio-cervico-mandibular system and TMD. Skull-atlas and atlas-axis rotations may play an important role in the aetiology of TMD in individuals with TMD. Therefore, it is important to evaluate rotations in the skull-atlas-axis region for the treatment of TMD.

ABSTRACT

PURPOSE: The role of the choroid in Leber hereditary optic neuropathy (LHON) remains unclear. The literature is scarce, with conflicting results and lacks axial length measurements. Therefore, we aimed to analyse the choriocapillaris (CC) vessel density (VD) and choroidal thickness (ChT) in all stages of LHON using swept source (SS) technology and considering the possible influence of axial length on choroidal parameters.

METHODS: This was a prospective cross-sectional observational study. A total of 119 eyes of 60 patients with molecularly confirmed LHON across all stages and 120 eyes of 60 control participants were included. We obtained the CC VD using optical coherence tomography angiography maps centred on the fovea. ChT was measured from the Bruch’s membrane to the choroid-sclera interface in the macular and peripapillary regions.

RESULTS: The CC VD was not significantly affected in any sector or average, except for a slight change in the superior region of chronic eyes (52.08 ± 1.62% vs. 53.50 ± 2.29%, p = 0.002). ChT demonstrated a trend towards decreased values in asymptomatic eyes and increased values in the symptomatic stages that failed to reach statistical significance in sectors corresponding to the papillomacular bundle except for the macular nasal inner sector of chronic eyes (281.10 ± 67.12 μm vs. 252.08 ± 70.55 μm, p = 0.045). No significant correlations were observed between visual acuity and CC VD or ChT.

CONCLUSION: The CC VD remained stable across the LHON stages. Choroidal vasculature does not appear to play a role in LHON pathophysiology. Further research is needed on ChT as a potential biomarker of LHON.

ABSTRACT

INTRODUCTION: Carbon-assisted Q-switched Nd:Yag laser treatment consists in applying a topical carbon suspension all over the face followed by irradiation with a Q-switched 1064 Nd:YAG laser. The delivery of multiple microdroplets of dilute Onabotulinum Toxin-A into the dermis, has been investigated as a tool for facial rejuvenation. The aim of this study is to assess the effectiveness of the combined treatment with botulinum toxin and carbon peel laser (performed with a standardized technique) in patients with seborrhea, dilated pores and wrinkles, and to demonstrate its benefits in improving the overall skin aspect.

MATERIAL AND METHODS: Patients enrolled in this prospective pilot study were subjected to 3 sessions of the combined treatment carried out 3 months apart. To evaluate the improvement of skin texture, wrinkles, dilated pores and acne lesions, several scales have been used, namely Fitzpatrick Wrinkle Assessment Scale (FWAS), the Physician Global Aesthetic Improvement Scale (GAIS), a photographic scale for the pore assessment and the Investigator Global Assessment of Acne (IGA). Face Q was also administered to assess patients’ satisfaction. The scores obtained were compared using a paired T-test.

RESULTS: Twenty patients were recruited. Difference of pre and post-treatment scores of the FWAS, GAIS, IGA, Face Q and the photographic scale for the pore assessment were statistically significant (p < 0,05).

CONCLUSIONS: This combined protocol could be considered as an useful tool to treat skin flaws affecting texture, microroughness and seborrhea and to reduce enlarged pore size and its versatility allows customized treatment with minimum discomfort in patients.

ABSTRACT

BACKGROUND: Primary liver cancer (PLC) has placed an increasing economic and resource burden on the health care system of the United States. We attempted to quantify its epidemiology and associated costs using a national inpatient database.

METHODS: Hospital discharge and insurance claims data from the National Inpatient Sample were used to conduct this analysis. Patients diagnosed with PLC (hepatocellular carcinoma or cholangiocarcinoma) were included in the study population, which was then stratified using patient demographics, comorbidities, degree of cancer spread, liver disease complications, and other descriptors. Trends were analyzed via regression curves for each of these strata from the years 2016 to 2019, with special attention to patterns in hospitalization incidence, inpatient mortality rate, total costs, and average per-capita costs. The resulting curves were evaluated using goodness-of-fit statistics and P-values.

RESULTS: Aggregate hospitalization incidence, inpatient mortality rates, and total costs were found to significantly increase throughout the study period (P=0.002, 0.002, and 0.02, respectively). Relative to their demographic counterparts, males, White Americans, and those older than 65 years of age contributed the largest proportions of total costs. These population segments also experienced significant increases in total expenditure (P=0.04, 0.03, and 0.02, respectively). Admissions deemed to have multiple comorbidities were associated with progressively higher total costs throughout the study period (P=0.01). Of the categorized underlying liver diseases, only admissions diagnosed with alcoholic liver disease or nonalcoholic fatty liver disease saw significantly increasing total costs (P=0.006 and 0.01), although hepatitis C was found to be the largest contributor to total expenses.

CONCLUSIONS: From 2016 to 2019, total costs, admission incidence, and inpatient mortality rates associated with PLC hospitalization increased. Strata-specific findings may be reflective of demographic shifts in the PLC patient populations, as well as changes in underlying chronic liver disease etiologies.

ABSTRACT

BACKGROUND: Pancreatic cancer is the third leading cause of cancer deaths in the United States. Despite decreasing cancer mortality rates as a whole, pancreatic cancer death rates in the United States remain steady and demonstrate racial/ethnic disparities. Divergent cancer mortality trends have also been observed between metro and nonmetro populations. We therefore aimed to compare metro and nonmetro trends in pancreatic cancer mortality rates in the United States from 1999 to 2020 and investigate potential sex and racial/ethnic differences.

METHODS: We analyzed National Center for Health Statistics data for all pancreatic cancer deaths among individuals aged 25 years or older in the United States. We estimated the average annual percent change (AAPC) in age-standardized pancreatic cancer mortality rates in metro versus nonmetro areas by sex and race/ethnicity.

RESULTS: Of the total 810,425 pancreatic cancer-related deaths identified from 1999 to 2020, 668,547 occurred in metro areas and 141,878 in nonmetro areas. Non-Hispanic Black individuals had the highest rates of pancreatic cancer mortality regardless of metropolitan status. In both metro and nonmetro areas, pancreatic cancer mortality rates among non-Hispanic White individuals increased over the study period (AAPC: metro, males, 0.32%; females, 0.27%; nonmetro, males, 0.77%; females, 0.62%). Non-Hispanic Black individuals in metro areas had a decrease in pancreatic cancer mortality (AAPC: males, -0.25%; females, -0.29%), but rates among non-Hispanic Black women in nonmetro areas increased (AAPC, 0.49%).

CONCLUSIONS: There are variations not only in pancreatic cancer mortality by metro and nonmetro status but also by sex and race/ethnicity within these areas. Individuals who live in nonmetro areas have higher pancreatic cancer mortality rates and increasing death rates compared with their metro counterparts. These findings highlight the need for targeted cancer prevention strategies that are specific to metro or nonmetro populations.

ABSTRACT

BACKGROUND: Acute gastric variceal bleeding (AGVB) is a potentially fatal consequence of portal hypertension, accounting for 10% to 30% of all variceal bleeding. Although endoscopic cyanoacrylate glue injection is a common treatment for acute hemostasis, it has been linked to significant side effects. In the treatment of AGVB, there is limited evidence of the efficacy and relative safety of endoscopic human thrombin injection over glue injection.

MATERIALS AND METHODS: A total of 52 AGVB patients were randomized to receive either thrombin injection (25 patients) or glue injection (27 patients). The primary outcome was the incidence of any glue or thrombin injection-related post-therapy complications. Initial hemostasis, rebleeding, and mortality were all secondary end goals.

RESULTS: Both groups had comparable baseline data. Hemostasis of active bleeding at endoscopy was 100.0% (10/10) in the thrombin group and 87.5% (7/8) in the glue group (P=0.44). Treatment failure after 5 days occurred in 2 patients (6.1%) in the glue group compared with none in the thrombin group (P=0.165). Between 6 and 42 days after index bleeding, rebleeding occurred in 4 patients in the thrombin group compared with 6 patients in the glue group (P=0.728). In the thrombin group, none of the patients had post-treatment ulcers on gastric varices compared with 14.81% (4/27) that occurred in the glue group (P=0.045), a statistically significant observation. Overall, complications occurred in 4 (20%) and 11 (40.7%) patients in the thrombin and glue groups, respectively (P=0.105). Two patients in the glue group died.

CONCLUSION: To achieve successful AGVB hemostasis, endoscopic thrombin injection has been proven efficacious. However, glue injection may be linked to a higher rate of rebleeding and post-therapy gastric variceal ulceration compared with thrombin.

ABSTRACT

PURPOSE OF STUDY: The project aimed to determine the impact of a standardized bowel regimen protocol for patients receiving opioids on the rate of stool softener prescription, occurrence of bowel movements of oncology patients, and improving the length of stay (LOS).

PRIMARY PRACTICE OF SETTING: Oncology unit in a community hospital.

METHODOLOGY AND SAMPLE: A posttest design was utilized, and a prospective medical record review of patients was completed after 8 weeks of the pilot study. The study sample (N = 164) included oncology patients admitted to a community hospital in the Southeast. The χ2 test was used to determine the impact of implementing a bowel panel order on the rate of stool softener prescriptions, the occurrence of bowel movements, and the LOS.

RESULTS: Only 43% (n = 40) of the patients from the comparison group were ordered laxatives, and more patients from the intervention group (68%; n = 49) received the bowel regimen protocol, whereas 26% (n = 19) of the patients used a laxative or stool softener using providers’ preference and demonstrated statistical significance (p = .001). In the intervention group, 93% of the patients (n = 67) reported having bowel movements compared with the comparison group, whereas only 32% (n = 32) demonstrated statistical significance (p = .001). The average LOS in the intervention group is less than 9 days compared with the comparison group, which was at 9 days (p = .001).

IMPLICATIONS TO CASE MANAGEMENT PRACTICE: Case managers play a critical role in coordinating care, improving transitions of care, and reducing LOS. Case managers can have a significant impact by monitoring and reminding nurses to report the gastrointestinal movements of oncology patients and then escalate opioid-induced constipation with the providers immediately. Case managers can facilitate the implementation of bowel regimen protocols, which may reduce hospitalizations and enhance patient outcomes, by taking this action.

ABSTRACT

AIM: Chronic graft versus host disease (cGVHD) is a major cause of morbidity postallogeneic peripheral blood stem cell transplant (PBSCT). There is paucity of literature describing incidence, risk factors, characteristics, and outcome of cGVHD in children undergoing haploidentical PBSCT with post-transplant cyclophosphamide (PTCy). Here, we describe our experience from our center regarding the same.

METHODS: All children who underwent haploidentical PBSCT with PTCy between January 2016 and December 2021 at our center and survived beyond day+100 post-transplant were included in this retrospective study. Conditioning regimens used were: Thiotepa-Fludarabine-Cyclophosphamide with 2 Gy single fraction total body irradiation, Thiotepa-Busulfan-Fludarabine, Fludarabine-total body irradiation and Fludarabine-Melphalan. Peripheral blood was used as stem cell source in all patients. GVHD prophylaxis was PTCy 50 mg/kg on day +3 and +4, Mycophenolate mofetil and Calcineurin inhibitors. Clinical and laboratory data was electronically retrieved and analyzed based on National Institute of Health Consensus Criteria-2014 at regular intervals. Impact of various patient, donor, and transplant-related factors on development of cGVHD were analyzed. Incidence of relapse, event free survival (EFS) and overall survival (OS) were calculated and compared between cGVHD and no cGVHD groups. Patients with rejection were excluded from risk factor analysis for cGVHD but were considered for survival analysis.

RESULTS: Fifty-one children included in this study. Median age of transplant of our cohort was 7.5 years with male:female=1.6:1. Eight patients had rejection with autologous recovery. History of acute GVHD (aGVHD) was present in 15/51 (Grade III to IV in 7/51). cGVHD developed in 19/51 patients (mild-9/51, moderate-6/51, and severe-4/51). Skin was the most common organ involved (100%) followed by gastrointestinal tract (47.4%), liver (36.8%), eyes (21%), lungs (21%), mouth (15.7%), and joints (5.2%). Advanced donor age (>30 y) and previous aGVHD were found to be significantly associated with increased risk of developing cGVHD. At last follow-up, complete response and partial response of cGVHD was seen in 6/19 and 4/19 patients, respectively. Overall mortality was 15/51 (cause of mortality was relapse of cancer 8/15, cGVHD-3/15, other 4/15). EFS and OS of full cohort was 55% and 70.6%, respectively. Compared with patients without cGVHD, patients with cGVHD demonstrated a lower relapse (18.2% vs. 40%, P=0.2333), higher EFS (68.4% vs. 53.1%, P=0.283), and higher OS (73.7% vs. 68.8%, P=0.708).

CONCLUSION: Incidence of cGVHD was high in children undergoing haploidentical PBSCT with PTCy. Other than PBSC graft source; donor age and previous aGVHD were the risks factors for development of cGVHD. Patients with cGVHD had lower incidence of relapse translating into better survival but this difference was not statistically significant.

ABSTRACT

OBJECTIVE: To compare the long-term overall survival (OS) of right versus left thoracic esophagectomy, and to evaluate whether surgical quality impacts comparison result.

BACKGROUND: Controversy regarding the optimal thoracic esophagectomy approach persists for esophageal squamous cell carcinoma (ESCC). No study has assessed the effect of surgical quality in comparison between right and left approaches.

METHODS: We consecutively recruited 5556 operable ESCC patients from two high-volume centers in China, of whom 2220 and 3336 received right and left thoracic esophagectomy, respectively. Cumulative sum was used to evaluate the learning curve for operation time of right approach, as the indicator of surgical proficiency.

RESULTS: With a median follow-up of 83.1 months, right approach, harvesting more lymph nodes, tended to have a better OS than left approach (Mean: 23.8 vs. 16.7 nodes; adjusted HR=0.93, 95% CI: 0.85-1.02). Subset analysis by the extent of lymphadenectomy demonstrated that right approach with adequate lymphadenectomy (≥ 15 nodes) resulted in statistically significant OS benefit compared with left approach (adjusted HR=0.86, 95% CI: 0.77-0.95), but not with limited lymphadenectomy. Subset analysis by surgical proficiency showed that proficient right approach conferred a better OS than left approach (adjusted HR=0.75, 95% CI: 0.64-0.88), but improficient right approach did not have such survival advantage.

CONCLUSIONS: Surgical quality plays a crucial role in survival comparison between surgical procedures. Right thoracic esophagectomy performed with adequate lymphadenectomy and surgical proficiency, conferring more favorable survival than left approach, should be recommended as the preferred surgical procedure for localized ESCC.
