Croatian Translation and Validation of the Patient Satisfaction with Nursing Care Quality Questionnaire (PSNCQQ).

Patient satisfaction is a crucial measure of the quality of healthcare, especially with regard to nursing services in hospital settings. Understanding and increasing patient satisfaction with nursing care is critical to improving overall healthcare and ensuring positive patient experiences during their hospital stay. The aim of this research was to evaluate the psychometric properties of the Croatian version of the Satisfaction with Nursing Care Quality Questionnaire (PSNCQQ), test the reliability and validity of the tool after translation, and investigate differences in patient satisfaction based on demographic variables, as well as their contribution to satisfaction with the quality of nursing care. After translation and adaptation, the Croatian version of the PSNCQQ was applied to 350 hospitalized patients (average age 51.19 years (range: 18-87)), of whom 194 (55.4%) were men and 156 (44.6%) were women. The results showed high internal consistency (Cronbach's α = 0.977) and confirmed the one-factor structure of the questionnaire, explaining 70.64% of the total variance. Confirmatory factor analysis supported the unidimensional model, showing strong fit indices (χ2 = 583.047, df = 149, p < 0.001, GFI = 0.861, AGFI = 0.818, NFI = 0.936, TLI = 0.946, CFI = 0.955, RMSEA = 0.080, PCLOSE < 0.001). In conclusion, the validation of the PSNCQQ in the Croatian language increases resources for evaluating and improving the quality of nursing care. This research lays the foundation for future studies and practical applications aimed at improving patient satisfaction and nursing care outcomes in Croatia, but there are also limitations to this study, including its one-institution scope, the possible influence of factors outside the current treatment on satisfaction, and the lack of comparison with objective clinical indicators.

Evaluation of PD-L1 Expression in Colorectal Carcinomas by Comparing Scoring Methods and Their Significance in Relation to Clinicopathologic Parameters.

BACKGROUND: This study aims to evaluate PD-L1 expression in colorectal carcinomas (CRCs) by using the tumor proportion score (TPS) and the combined positive score (CPS), and to investigate whether there is a correlation with clinicopathologic features. METHODS: A cross-sectional study was conducted that included samples from patients with colorectal adenocarcinoma treated with colon resection and rectal resection after neoadjuvant radio- and chemotherapy at the Department of Abdominal Surgery at Pozega Hospital in the period from 2017 to 2022. The study included 102 tumor tissue samples from patients after resection and the pathohistological diagnosis of adenocarcinoma. RESULTS: In our study, the PD-L1 positivity rate after the TPS was 42 (41%) samples, and after the CPS, 97 (95%) of them (p < 0.001). The positive expression of PD-L1 in tumor cells using the TPS method showed a statistically significant association with adenocarcinoma (TPS ≥ 10-50% and ≥50%). There were significantly more that were moderately differentiated, with TPS ≥ 50%, and those poorly differentiated had values ≥ 10-50%. There were significantly more patients with a status of more than one positive lymph node with TPS values ≥ 10-50%. Patients without metastases in the lymph nodes are significantly more likely to have CPS values > 50%, compared with other lymph node statuses. CONCLUSIONS: These results suggest that the total number of PD-L1-expressing cells, including tumor and immune cells, is a more sensitive biomarker than the number of PD-L1-expressing tumor cells alone in CRC.

Influence of Personality Traits and Organizational Justice on Job Satisfaction among Nurses.

The purpose of this research was to examine whether demographic variables, personality traits, and workplace variables (working in shifts, job tenure, and perceived organizational justice) contribute the most to the prediction of job satisfaction in nurses. The survey included 161 nurses. The instruments used in this research were as follows: the Demographic Data Questionnaire, the Perceived Organizational Justice Scale, the Job Satisfaction Scale, and the NEO five-factor inventory. The study findings indicated that age, health status, distributive justice, and procedural justice positively contribute to job satisfaction among nurses, while neuroticism contributes negatively. Older nurses, those in better health, those who are satisfied with the organization's decision-making process, and those who feel adequately rewarded for their contributions tend to be more satisfied with their jobs. Conversely, nurses with a higher level of the neuroticism personality trait tend to be less satisfied with their job. The strongest predictors of job satisfaction among nurses were found to be health status, the personality trait of neuroticism, and distributive and procedural justice, with the age of nurses being slightly less powerful but still significant.

Esophagogastric anastomosis in rats: Improved healing by BPC 157 and L-arginine, aggravated by L-NAME.

AIM: To cure typically life-threatening esophagogastric anastomosis in rats, lacking anastomosis healing and sphincter function rescue, in particular. METHODS: Because we assume esophagogastric fistulas represent a particular NO-system disability, we attempt to identify the benefits of anti-ulcer stable gastric pentadecapeptide BPC 157, which was in trials for ulcerative colitis and currently for multiple sclerosis, in rats with esophagocutaneous fistulas. Previously, BPC 157 therapies have promoted the healing of intestinal anastomosis and fistulas, and esophagitis and gastric lesions, along with rescued sphincter function. Additionally, BPC 157 particularly interacts with the NO-system. In the 4 d after esophagogastric anastomosis creation, rats received medication (/kg intraperitoneally once daily: BPC 157 (10 µg, 10 ng), L-NAME (5 mg), or L-arginine (100 mg) alone and/or combined or BPC 157 (10 µg, 10 ng) in drinking water). For rats underwent esophagogastric anastomosis, daily assessment included progressive stomach damage (sum of the longest diameters, mm), esophagitis (scored 0-5), weak anastomosis (mL H2O before leak), low pressure in esophagus at anastomosis and in the pyloric sphincter (cm H2O), progressive weight loss (g) and mortality. Immediate effect assessed blood vessels disappearance (scored 0-5) at the stomach surface immediately after anastomosis creation. RESULTS: BPC 157 (all regimens) fully counteracted the perilous disease course from the very beginning (i.e., with the BPC 157 bath, blood vessels remained present at the gastric surface after anastomosis creation) and eliminated mortality. Additionally, BPC 157 treatment in combination with L-NAME nullified any effect of L-NAME that otherwise intensified the regular course. Consistently, with worsening (with L-NAME administration) and amelioration (with L-arginine), either L-arginine amelioration prevails (attenuated esophageal and gastric lesions) or they counteract each other (L-NAME + L-arginine); with the addition of BPC 157 (L-NAME + L-arginine + BPC 157), there was a marked beneficial effect. BPC 157 treatment for esophagogastric anastomosis, along with NOS-blocker L-NAME and/or NOS substrate L-arginine, demonstrated an innate NO-system disability (as observed with L-arginine effectiveness). BPC 157 distinctively affected corresponding events: worsening (obtained with L-NAME administration that was counteracted); or amelioration (L-arginine + BPC 157-rats correspond to BPC 157-rats). CONCLUSION: Innate NO-system disability for esophagogastric anastomoses, including L-NAME-worsening, suggests that these effects could be corrected by L-arginine and almost completely eliminated by BPC 157 therapy.

Brain-gut Axis and Pentadecapeptide BPC 157: Theoretical and Practical Implications.

BACKGROUND: Brain-gut interaction involves, among others, peptidergic growth factors which are native in GI tract and have strong antiulcer potency and thus could from periphery beneficially affect CNS-disorders. We focused on the stable gastric pentadecapeptide BPC 157, an antiulcer peptidergic agent, safe in inflammatory bowel disease trials and now in multiple sclerosis trial, native and stable in human gastric juice. METHODS: Review of our research on BPC 157 in terms of brain-gut axis. RESULTS: BPC 157 may serve as a novel mediator of Robert's cytoprotection, involved in maintaining of GI mucosa integrity, with no toxic effect. BPC 157 was successful in the therapy of GI tract, periodontitis, liver and pancreas lesions, and in the healing of various tissues and wounds. Stimulated Egr-1 gene, NAB2, FAK-paxillin and JAK-2 pathways are hitherto implicated. Initially corresponding beneficial central influence was seen when BPC 157 was given peripherally and a serotonin release in particular brain areas, mostly nigrostriatal, was changed. BPC 157 modulates serotonergic and dopaminergic systems, beneficially affects various behavioral disturbances that otherwise appeared due to specifically (over)stimulated/damaged neurotransmitters systems. Besides, BPC 157 has neuroprotective effects: protects somatosensory neurons; peripheral nerve regeneration appearent after transection; after traumatic brain injury counteracts the otherwise progressing course, in rat spinal cord compression with tail paralysis, axonal and neuronal necrosis, demyelination, cyst formation and rescues tail function in both short-terms and long-terms; after NSAIDs or insulin overdose or cuprizone encephalopathies were attenuated along with GI, liver and vascular injuries. CONCLUSION: BPC 157, a gastric peptide, may serve as remedy in various CNS-disorders.

The use of piezoelectric effect to improve instrument quality and patient safety in laparoscopic surgery.

The piezoelectric properties of some natural crystals and polymers can also be used in surgery. For this purpose, a prototype of an endoscopic instrument was constructed with piezoelectric material attached to its working end with the aim of recognizing pulsating blood vessels during laparoscopic surgery. To test the properties of the new instrument in laboratory conditions, simulated blood circulation was used with the possibility of changing pressure and frequency. The instrument was tested in the pressure range of 40-180 mm Hg at constant frequency of 72/min and frequency range of 36-130 beats per minute at constant pressure of 120 mm Hg. Test results showed that the instrument with certainty recognized a pulsating "blood vessel" in the expected pressure ranges and at different blood pump frequencies. Given the piezoelectric material's very small dimensions and flexible form, it can be installed at the working end of most standard laparoscopic instruments and thus significantly increase certainty in the recognition of arteries during surgery, which would reduce the possibility of their injury or accidental ligation.
