Does Pneumococcal Vaccination Have an Effect on Hospital Costs?

OBJECTIVE: It is known that inpatient hospital costs are much higher than outpatient services. It was aimed to investigate the effect of pneumococcal vaccination on hospitalizations. MATERIAL AND METHODS: The direct hospitalization costs, length of stay, and factors of the vaccinated and unvaccinated patients in the same hospital during the 12-month follow-up of the patients who received pneumococcal vaccine between November 15, 2018, and November 15, 2020, in 3 chest diseases and thoracic surgery training and research hospitals were analyzed by obtaining Hospital Information Management System records. Data were collected with Statistical Package for the Social Sciences version 23 program (IBM Corp.; Armonk, NY, USA) , and statistical evaluation was made. RESULTS: The mean age of 800 hospitalized patients, of whom 400 were unvaccinated and 400 were vaccinated, was 68.48 ± 11.97. There was no significant difference in the mean age of vaccinated and unvaccinated patients (P > .05). Five hundred sixty-six patients (70.8%) were aged 65 and over. Two hundred eighty (51.2%) of men were vaccinated and 120 (47.2%) of women were vaccinated, and there was no significant difference (P > .05). The mean hospital stay of these patients was 11.01 days, and those in the vaccinated group had an average mean hospital stay of 9.11 days and those in the unvaccinated group had a mean hospital stay less than 12.91 days (P < .001). Total 1-year hospitalization costs were $501.653.53 and the cost per person was calculated as $627.07. The cost per capita for the vaccinated group was $550.52, which was lower than the average cost of the unvaccinated group ($703.62) (P < .05). When comparing the status of being vaccinated, comorbidity, mortality, mean length of stay, chronic obstructive pulmonary disease, and heart disease were found to be statistically significant (P < .05). CONCLUSION: In our study, it was revealed that vaccination of patients hospitalized in chest disease hospitals with the pneumococcal vaccine reduced the average length of hospital stay by 41.7% and the cost of hospitalization by 27.8%.

The Significance of Skip Mediastinal Lymph Node Metastasis in the Prognosis of Patients with Resected Non-Small-Cell Lung Carcinoma: Is It Really a Better N2 Disease Subtype?

OBJECTIVE: In this study, we aimed to reveal the prognostic differences between skip and non-skip metastasis mediastinal lymph node (MLN) metastasis. METHODS: A total of 202 patients (179 males and 23 females; mean age, 59.66 ± 9.89 years; range: 29-84 years) who had ipsilateral single-station MLN metastasis were analyzed in two groups retrospectively between January 2009 and December 2017: "skip ipsilateral MLN metastasis" group (sN2) (n = 55,27.3%) [N1(-), N2(+)], "non-skip ipsilateral MLN metastasis" group (nsN2) (n = 147,72.7%) [N1(+), N2(+)]. RESULTS: The mean follow-up was 42.63 ± 34.91 months (range: 2-117 months). Among all patients, and in the sN2 and nsN2 groups, the median overall survival times were 63.5 ± 4.56, 68.8 ± 7, and 59.3 ± 5.35 months, respectively, and the 5-year overall survival rates were 38.2%, 46.3%, and 36.4%. CONCLUSION: Skip metastasis did not take its rightful place in TNM classification; thus, further studies will be performed. To detect micrometastasis, future studies on skip metastasis should examine non-metastatic hilar lymph nodes (LNs) through staining methods so that heterogeneity in patient groups can be avoided, that is, to ensure that only true skip metastasis cases are included. Afterwards, more accurate and elucidative studies on skip metastasis can be achieved to propound its prognostic importance in the group of N2 disease.

Could ferritin level be an indicator of COVID-19 disease mortality?

While the number of coronavirus disease-2019 (COVID-19) cases is increasing day by day, there is limited information known about the hematological and laboratory findings of the disease. We aimed to investigate whether serum ferritin level predicts mortality is a marker for rapid progression for inpatients. Our study included 56 patients who were died due to COVID-19 as the study group, and 245 patients who were hospitalized and recovered as the control group. The laboratory data of the patients were evaluated from the first blood tests (pre) taken from the first moment of admission to the hospital and the blood tests taken from before the patient's discharge or exitus (post) were evaluated retrospectively. The mean age of the nonsurvivor group was 62.0 ± 15.7 and the mean age of the control group was 54.34 ± 13.03. Age and length of stay are significantly higher in the nonsurvivor group. When comparing the pre- and postvalues of ferritin, according to the two groups separately, there was no significant difference in the control group and a high level of significance was observed in the nonsurvivor group (p < .01). COVID-19 disease caused by severe acute respiratory syndrome coronavirus-2 causes high mortality with widespread inflammation and cytokine storm. Ferritin is a cheap and widespread available marker, ferritin, which can be used for its predictivity of the mortality and hope it would be a useful marker for clinicians for the management of the disease.

Does the Hospital Admission of Patients with Respiratory Disease Increase in Izmir When the PM10 Level is High?

OBJECTIVES: Air pollution is caused by exhaust emissions from motor vehicles, fuel consumption for heating of residences, and especially emissions from industrial facilities around the world. The exposure to outdoor air pollution has been associated with acute and chronic health problems, from irritation to death. In this study, we aimed to determine whether air pollution increases the frequency of hospital admission and whether there is a difference between disease subgroups, age, and gender, in the 2-year period in Izmir province where - air pollution is increasing. MATERIALS AND METHODS: Collection of health data for the project compiled by the Ministry of Health, in cooperation with the Izmir Provincial Health Directory Information Processing Department, and information obtained on the age groups, gender, admission time, and diagnosis of illness [International Classification of Diseases (ICD)10 code] on the residents of Izmir in 2016/2017. RESULTS: The daily numbers of patients with respiratory complaints and air pollution were found to be related. Both air pollution and the admission rate increase in the January-March period. In male patients, the risk of hospitalization increases for 1.14%. Males had a higher increase in the rate of diagnosis of chronic rhinitis (increase of 6.22%) than females who had an increase of 0.97%. It was observed that there was a 2.62% increase in the incidence of bronchiectasis, 2.53% in that of asthma, and 2.49% in that of dyspnea. CONCLUSION: There was a significant increase in respiratory diseases during the days when the air pollution was high, and this was observed as the upper respiratory tract infection and acute bronchitis in the young group and chronic respiratory diseases in the elderly group upon hospital admissions. The reduction of air pollutants and inhalation of clean air are the most important aspects in providing a healthier and longer life.

Fully endoscopic interlaminar and transforaminal lumbar discectomy: clinical results of 857 surgically treated patients.

Minimally invasive surgical techniques are becoming increasingly common in spinal surgery in an attempt to decrease tissue trauma during surgery, which in turn decreases post-operative pain and opioid use. The aim of this study was to investigate the clinical outcomes of a large group of patients with lumbar disc disease who underwent full endoscopic surgery. 857 patients who underwent fully endoscopic lumbar discectomy were investigated retrospectively. General demographics were evaluated in terms of mean operating time, mean length of hospital stay, mean time to return to work, complications and recurrences. Clinical outcomes were evaluated using visual analogue scale (VAS) for low back and leg pain, and Oswestry Disability Index (ODI) for functional assessment. The mean follow-up time was 36 months. The operation time ranged from 20 to 65 minutes (39 min on average), and there was no measurable intraoperative blood loss. Patients were mobilised on average 3.5 hours after the surgery. The length of hospital stay after the operation was 12-24 hours (18 hours on average). During postoperative follow-up, 19 patients required revision surgery due to recurrence (2.2%). There was one case of nerve root injury in which the patient recovered well following physical therapy, and 11 cases of paresthesia that gradually improved following 2-6 weeks of rehabilitation and treatment with pregabalin. All types of lumbar disc herniations are accessible via the full-endoscopic technique. Full-endoscopic discectomy, as a minimally invasive procedure, has the technical advantages of less paraspinal muscle dissection, less tissue trauma, less risk of spinal instability, and minimal blood loss.

Investigation of vascular endothelial dysfunction in the patients with age-related macular degeneration.

PURPOSE: This study aims to evaluate the association between age-related macular degeneration (AMD) and cardiovascular disease by using the noninvasive flow-mediated dilation (FMD) test to show endothelial dysfunction as an indicator of subclinical atherosclerosis. METHOD: Participants in this study included 30 dry AMD patients, 30 wet AMD patients, and 30 healthy controls without any systemic disease, including AMD. FMD and the intima media thickness (IMT) of the carotid artery were compared between the groups. RESULTS: Comparison of FMD between the groups showed a 10.96% brachial artery dilation in the healthy controls, 3.99% in the dry AMD group, and 5.03% in the wet AMD group. While a significant difference was not observed between the wet and dry AMD groups, comparison of the control group to the wet and dry AMD groups yielded a significant difference. When brachial artery dilation below 7% was accepted as an abnormal FMD, 26.7% of the healthy controls, 66.7% of the dry AMD patients and 76.7% of the wet AMD patients were found to be abnormal. Similarly, while no significant difference was observed between the wet and dry AMD groups, comparison of the control group with the wet and dry AMD patients yielded a significant difference. When an IMT below 0.7 mm was accepted as abnormal, 26.7% of the healthy controls, 33.3% of the dry AMD, and 43.3% of the wet AMD were found to have an abnormal IMT. However, differences between the groups did not reach statistical significance. CONCLUSIONS: In this study, use of the FMD test showed endothelial dysfunction among AMD patients. No significant differences were found between the dry and wet AMD patient groups.
