RESUMEN
OBJECTIVE: Cervical cancer, linked to human papillomavirus (HPV), ranks fourth among women's cancers globally. Several studies have found an association between viral infections or cancer and dementia, which is a major public health concern. This study aimed to provide real-world data on the association between cervical cancer and the risk of dementia. METHODS: This population-based cohort study, utilizing Taiwan's National Health Insurance Research Database, included 53 905 patients, with 10 781 having cervical cancer, matching with 43 124 controls in a 1:4 ratio based on age and indexed date. Incidence density rates were used to calculate the incidence rate of dementia. Adjusting for comorbidities, a multivariable Cox proportional hazards regression model was used to estimate the hazard ratios and 95% confidence intervals. Additionally, the risk of dementia was further verified using the cumulative incidence analyzed by the Kaplan-Meier method. RESULTS: This study indicated a significantly higher dementia risk in the cervical cancer cohort compared with the non-cervical cancer cohort (adjusted HR (aHR)=1.64, 95% CI 1.16 to 2.26; p<0.001), suggesting a 1.64-fold increased risk. Notably, cervical cancer posed a greater risk of dementia (aHR=1.69, 95% CI 1.21 to 2.29; p<0.001) compared with carcinoma in situ of the cervix (p=0.18) and cervical intraepithelial neoplasia (p=0.23). The cumulative incidence of dementia in the cervical cancer group was significantly higher (log-rank test, p<0.001) than the control group. CONCLUSIONS: Cervical cancer (invasive disease) was associated with a significant risk of dementia, unlike carcinoma in situ of the cervix and cervical intraepithelial neoplasia (pre-invasive diseases), suggesting HPV infections may play a role in dementia, particularly oncogenic types. This highlights the importance of further investigation into the underlying mechanisms of the association between cervical cancer and dementia.

Introduction: Children and adolescents with autism spectrum disorder (ASD) may be particularly vulnerable to the impact of traumatic events, yet the association between ASD and the risk of developing acute stress disorder and post-traumatic stress disorder (PTSD) remains uncertain. This study aims to investigate this association, addressing the gap in large-scale evidence on the subject. Methods: Conducted as a retrospective and matched cohort study, data was sourced from the National Health Insurance Research Database (NHIRD) in Taiwan, spanning from January 1, 2000, to December 31, 2015. The study included patients aged 18 years or under newly diagnosed with ASD (n=15,200) and compared them with a matched control group (n=45,600). The Cox proportional regression model was employed to assess the risk of acute stress disorder and PTSD. Results: Over the 15-year follow-up period, a total of 132 participants developed either acute stress disorder or PTSD. Among them, 105 cases (0.691% or 64.90 per 100,000 person-years) were in the ASD group, while 27 cases (0.059% or 5.38 per 100,000 person-years) were in the control group. The adjusted hazard ratio for the ASD group was significantly higher compared to the control group (25.661 with 95% CI = 15.913-41.232; P < .001). Discussion: This study provides compelling evidence that individuals with ASD face an elevated risk of developing acute stress disorder and PTSD. The findings underscore the importance of clinicians recognizing and addressing this vulnerability in ASD individuals exposed to traumatic events. This emphasizes the need for heightened attention to the risk of PTSD and acute stress disorder in the ASD population.
RESUMEN
OBJECTIVE: Atypical antipsychotic-induced hyponatremia has been reported in patients with psychiatric disorders. To date, hyponatremia due to lurasidone, an atypical antipsychotic approved for the treatment of schizophrenia and bipolar depression, has never been reported. CASE REPORT: A female patient with bipolar depression and a history of subdural hematoma experienced a rapid onset of hyponatremia after the initiation of low-dose lurasidone. The hyponatremia worsened after the dose of lurasidone was increased and resolved only after lurasidone was ceased. According to the Naranjo Adverse Drug Reaction Probability Scale, this case report scores 6 as a possible drug reaction between lurasidone and hyponatremia. RESULTS: Based on laboratory results, the syndrome of inappropriate antidiuretic hormone secretion and thyroid or adrenal dysfunction as differential diagnoses were excluded. Lurasidone-induced polydipsia complicated by hyponatremia was confirmed. Lurasidone was subsequently discontinued. The sodium level returned to normal within 1 week without any sodium supplementation. CONCLUSIONS: This case report highlighted that low-dose lurasidone may induce polydipsia complicated by hyponatremia. Physicians should be aware of the adverse reactions of hyponatremia associated with lurasidone, particularly in patients with a history of intracranial hemorrhage.
