Abstract
Abstract:
Background
CAP ( community acquired pneumonia ) is one of the most common infectious diseases that leads to hospitalization of patients. Also, the effects of vitamin D deficiency on the functioning of the immune system and its association with infectious diseases such as CAP have received much attention in recent years. Therefore, we decided to investigate the relationship between serum vitamin D levels and the incidence and severity of CAP pneumonia in this study.
Methods
In this case-control study, 75 patients with CAP and 75 healthy individuals were evaluated and serum levels of vitamin D in these two groups were measured and compared.
Results
The present study shows that for each unit increase in serum vitamin D level, the need for hospitalization in the ICU according to the IDSA criterion is reduced by seven percent and according to the CURB65 criterion, the need for hospitalization in the ward and ICU is reduced by fifteen percent. Vitamin D deficiency also increases the chance of developing community-acquired pneumonia by 3.08 times. And for every unit increase in vitamin D, the chance of developing community-acquired pneumonia decreases by 4 percent. And in people with vitamin D deficiency, the chance of being admitted to the ICU according to IDSA is 2.05 times and according to CURB65 is 2.84 times.
Conclusions
Overall, based on the results of this study, it is concluded that vitamin D deficiency is associated with an increased incidence as well as a greater severity of community acquired pneumonia.

Abstract
Introduction: Sequential word learning is a crucial aspect of memory research in cognitive neuroscience, emphasizing the importance of recalling words at the beginning (primacy) and end (recency) of a sequence. This study aims to investigate the extent of primacy and recency effects in patients with neglect syndrome caused by right parietal lobe damage.
Methods: This case-control study involved 18 patients with parietal lobe tumors, divided into two groups: 9 patients with neglect syndrome and nine without. Patients referred to the neurosurgery department of Shahid Tajrish Hospital with right parietal lobe lesions underwent neurological and psychological evaluations, including the cancellation test, line bisection test, copying test, and the 5-point test. Those diagnosed with neglect syndrome formed the syndrome group, while the rest constituted the control group. Both groups participated in immediate recall (short-term memory) and delayed recall (long-term memory) tests for sequential word learning, with results analyzed for primacy and recency effects.
Results: Among the 18 patients, 61% were men and 39% were women. Analysis of immediate and short-term memory tests for sequential word learning revealed no significant differences in primacy and recency effects between the two groups.
Conclusions: The findings suggest that patients with right parietal lobe damage and neglect syndrome do not exhibit significant differences in primacy or recency effects in verbal memory during sequential word learning compared to the control group. Consequently, immediate and short-term memory appears relatively unaffected in these patients.
