Does Parkinson's disease affect sleep quality?

BACKGROUND: Parkinson's disease (PD) is a common neurodegenerative disease that is linked to several motor and nonmotor symptoms, including sleep disturbances. Patient quality of life has been shown to be disproportionally impacted by disease. OBJECTIVES: To investigate sleep quality among individuals with PD, and to assess the severity of sleep disturbances and their impact on daytime activities. SUBJECTS AND METHODS: A case‒control with 44 patients with Parkinson's disease and 80 apparently healthy control participants was recruited from several hospitals and clinics. Each participant provided a thorough medical history and underwent a physical examination, and a questionnaire comprising the standard PSQI was used to assess sleep quality. Independent samples t test and Spearman's correlation analysis were used with a p value equal to or less than 0.05 which was considered significant. RESULTS: The mean global PSQI score was 11.55 ± 4.412 for PD patients and 5.73 ± 3.22 for the control group with significant p value, Sleep latency onset was 75.57 min for PD patients and 22.81 min for the control group with significant p value. There was no significant correlation between age and other sleep-related variables. A total of 86.4% of patients with Parkinson's disease suffered from varying degrees of daytime dysfunction compared to 61.25% of the controls. CONCLUSION: Parkinson's disease patients had poorer sleep quality than the controls. Age and sex were not found to be expected as a factor for sleep quality in patients with Parkinson's disease. Daytime dysfunction rates are high in patients with Parkinson's disease.

Pregabalin versus Gabapentin Efficacy in the Management of Neuropathic Pain Associated with Failed Back Surgery Syndrome.

OBJECTIVE: Failed back surgery syndrome (FBSS) is a common long-term complication following spine surgeries characterized by chronic persistent pain; different strategies of management were employed to deal with it. This clinical trial aims to compare the efficacy of Pregabalin and Gabapentin in the management of this condition. METHODS: A double-blind, randomized, comparative study (clinical trial registry NCT05324761 on 11th April 2022) with two parallel arms with Pregabalin and Gabapentin were used in arms one and two, respectively. Visual analog scale was used for basal and endpoint assessment of pain. T-test and analysis of covariance were used to deal with different variables. A pairwise test was used to compare pairs of means. RESULTS: Of 66 patients referred to the trial, 64 were eligible, with 60 patients completing the 30 days trial. Both pregabalin and gabapentin effectively reduce pain, with significant p-values of 0.001 for each group. However, the pregabalin group was superior to gabapentin in pain reduction (p=0.001). Gender was an insignificant factor (p=0.574 and p=0.445 for the pregabalin and gabapentin groups, respectively, with a non-significant reduction (p=0.393) for both groups in total. Location of stenosis before surgery and type of surgery performed show non-significant effect on pain reduction for both groups. CONCLUSION: Both pregabalin and gabapentin effectively and safely relieve neuropathic pain associated with FBSS; pregabalin was significantly more effective irrespective of the patients' gender.

Sleep quality in COVID-19 recovered patients.

Objective: Novel coronavirus disease 2019 is known to have poor impacts on health with health systems facing serious challenges. Limited information is available on health issues for patients who have recovered from the disease. Our study aims to investigate the extent of sleep disorders in patients who have recovered from the coronavirus disease. Material and Methods: A casecontrol study with 256 patients who had recovered from coronavirus disease 2019 was carried out, with 491 patients enrolled as the control. All participants were 18 years or older, and sleep quality was assessed using the Pittsburgh sleep quality index. Furthermore, sleep latency and hours needed for sleep were calculated. Chi-square and t-test statistical methods were used to analyze the variables. Results: A total of 215 (84%) recovered patients were associated with poor sleep quality, with 384 patients (78%) in the control group. The PSQI values for recovered and control groups were 8.77±3.7591 and 8.139±3.068, respectively, with a significant p-value of 0.014. Average hours needed for sleep were 6.899±3.7869 and 6.44±1.477 for recovered and control patients, respectively, with a significant p-value of 0.01. The difference in sleep latency was non-significant (p=0.374), with 29.01±39.3702 and 33.520±38.208 minutes for recovered and control patients, respectively. Conclusion: Sleep disorders were more prevalent among patients who had recovered from COVID-19 than the control group.

Prevalence of pineal gland and choroid plexus calcification among iraqi patients attending CT scan units / Prevalencia de calcificación de la glándula pineal y del plexo coroideo entre pacientes iraquíes que asisten a las unidades de tomografía computarizada

SUMMARY: Pineal gland calcification is the most common physiological intracranial calcification followed by the choroid plexus calcification. The objective of the study was to determine the prevalence of the pineal gland and choroid plexus calcification among the Iraqi population attending computed tomography scan units in Baghdad, estimate the mean diameters of the pineal gland calcification, and to detect any correlation between these calcifications with age and sex. This multi-centric cross-sectional study examined 485 CT scans of Iraqi patients between the ages of 1 and 100 years attending CT scan units in the period 1 December 2018 to 1 April 2019. Descriptive and inferential statistics were used. The prevalence of pineal gland calcification was found to be 68 % with the 30-39 age group and male sex predominance. It was found to increase after the first decade of life without real consistency. The mean for pineal gland calcification anterior-posterior diameter was 4.55±2.13 and the mean of the right-left diameter was 3.95±1.54. These diameters were found to differ according to sex and age. Choroid plexus calcification was found to have a prevalence of 53.6 %. In most cases, choroid plexus calcification was found bilaterally (77.3 %). There was no difference in sex, but choroid plexus. In conclusion, calcification was noticed to increase gradually according to age. Both pineal gland and choroid plexus calcification have a relatively high prevalence. While pineal gland calcification formation was demonstrated to have a close relation to age and sex, choroid plexus calcification formation was noticed to relate only to age.

RESUMEN: La calcificación de la glándula pineal es la calcificación intracraneal fisiológica más común después de la calcificación del plexo coroideo. El objetivo del estudio fue determinar la prevalencia de calcificación de la glándula pineal y del plexo coroideo entre la población iraquí que asiste a las unidades de tomografía computarizada en Bagdad, estimar los diámetros medios de la calcificación de la glándula pineal y detectar la posible correlación entre estas calcificaciones con la edad y el sexo. Este estudio transversal multicéntrico examinó 485 tomografías computarizadas de pacientes iraquíes entre 1 y 100 años de edad que asistieron a unidades de tomografía computarizada en el período del 1 de diciembre de 2018 al 1 de abril de 2019. Se utilizaron estadísticas descriptivas e inferenciales. Se encontró una prevalencia de calcificación de la glándula pineal del 68 % con predominio del sexo masculino en el grupo de 30 a 39 años. Se observó que aumentaba después de la primera década de vida sin una coherencia real. La media del diámetro anteroposterior de la calcificación de la glándula pineal fue de 4,55 ± 2,13 y la media del DIÁ- METRO derecho-izquierdo fue de 3,95 ± 1,54; estos diámetros difieren según el sexo y la edad. La calcificación del plexo coroideo tiene una prevalencia del 53,6 %. En la mayoría de los casos, la calcificación del plexo coroideo se encontró de forma bilateral (77,3%). No hubo diferencia de sexo, no obstante en el plexo coroideo se observó que la calcificación aumentaba gradualmente según la edad. Tanto la calcificación de la glándula pineal como del plexo coroideo tienen una prevalencia relativamente alta. Si bien se demostró que la formación de calcificación de la glándula pineal está relacionada con la edad y el sexo, se observó que la formación de calcificación del plexo coroideo se relaciona solo con la edad.

Sleep Disorders Following Mild and Moderate Traumatic Brain Injury.

(1) Background: Sleeping disorders are frequently reported following traumatic brain injury (TBI). Different forms of sleeping disorders have been reported, such as sleepiness, insomnia, changes in sleeping latency, and others. (2) Methods: A case-control study with 62 patients who were victims of mild or moderate TBI with previous admissions to Iraqi tertiary neurosurgical centers were enrolled as the first group, and 158 patients with no history of trauma were considered as the control. All were 18 years of age or older, and the severity of the trauma and sleep disorders was assessed. The Pittsburgh sleep quality index was used to assess sleep disorders with average need for sleep per day and average sleep latency were assessed in both groups. Chi-square and t-test calculations were used to compare different variables. (3) Results: 39 patients (24.7%) of the controlled group experienced sleeping disorders compared to TBI group with 45 patients (72.6%), P-value < 0.00001. A total of 42 patients were diagnosed on admission as having a mild degree of TBI (mean GCS 13.22 ± 1.76) and 20 patients were diagnosed with moderate TBI (mean GCS11.05 ± 1.14. 27). A total of 27 (46.28%) patients with mild severity TBI and 18 patients (90%) of moderate severity were considered to experience sleeping disorders, P-value 0.0339. Each of the mild and moderate TBI subgroups show a P-value < 0.00001 compared to the control group. Average sleep hours needed per day for TBI and the control were 8.02 ± 1.04 h and 7.26 ± 0.58 h, respectively, P-value < 0.00001. Average sleep latency for the TBI and the control groups were 13.32 ± 3.16 min and 13.93 ± 3.07 min respectively, P-value 0.065. (4) Conclusion: Sleep disturbances are more common following mild and moderate TBI three months after the injury with more hours needed for sleep per day and no significant difference in sleep latency. Sleep disturbances increase in frequency with the increase in the severity of TBI.
