Article Abstract
Background: Previous studies examined the effect of laparoscopic cholecystectomy (LC) versus open cholecystectomy (OC) on physiological variables of the respiratory system. In this study we compared changes in arterial blood gases-related parameters between LC and OC to assess their comparative influence on gas exchange.
Methods: We studied 28 patients, operated under identical anesthetic protocol (LC: 18 patients, OC: 10 patients). Measurements were made on the morning before surgery (BS), the second (AS2) and the eighth (AS8) postoperative day. Studied parameters, including alveolar-arterial difference in PO2 ((A-a)DO2) and oxygen content (Oct in vol%), were statistically compared.
Results: On AS2 a greater increase was found in ((A-a)DO2) for the OC compared to LC (4.673 ± 0.966 kPa versus 3.773 ± 1.357 kPa, respectively). Between BS and AS2, Oct in vol% decreased from 17.55 ± 1.90 to 15.69 ± 1.88 in the LC and from 16.99 ± 2.37 to 14.62 ± 2.23 in the OC, whilst a reduction (P = 0.093) between AS2 and AS8 was also found for the open method. Besides, on AS2, SaO2% decrease was greater in OC compared to LC (P = 0.096).
Conclusions: On AS2, the greater increase in OC-((A-a)DO2) associated with Oct in vol% and SaO2% findings also in OC group suggest that LC might be associated with lower risk for impaired tissue oxygenation.
Objective: Limited research exists regarding malpractice in dentistry. Temporomandibular joint disorders (TMDs) include intra- and extra-articular conditions that are managed by general dentists, orofacial pain specialists, and oral and maxillofacial surgeons. In this study, we investigate the rate of malpractice court trials involving treatment of TMD by these specialists.
Objective: To assess serum inflammatory biomarker levels in patients with different subtypes of diabetic macular edema (DME).
Methods: We retrospectively analyzed 50 eyes from 37 treatment-naïve DME patients who underwent intravitreal injection therapy between June and December 2023. Based on the morphological characteristics of macular edema in optical coherence tomography (OCT), the eyes were categorized into the cystoid macular edema (CME) group (n = 25) and diffuse retinal thickening (DRT) group (n = 25).

Background: This study aims to provide an estimated dataset of lens zonule balance tension (LZBT) measurements in cataractous lenses among Chinese patients and to conduct a statistical analysis of anterior segment parameters.
Methods: This is a cross-sectional study. We included a total of 833 eyes from 833 Chinese participants aged 23-91 years who underwent cataract surgery.
Background: In CT, the volumetric CT dose index (CTDI), dose-length product (DLP) and patient's size-specific dose estimates (SSDE) are used as diagnostic reference level (DRL) metrics.
Objectives: To develop clinical local DRL values for CT chest-abdomen-pelvis (CAP) examinations using the CTDI, DLP and SSDE, and to determine the image quality achieved.
Method: In total, 201 cancer patients were included in the study.
