The incidence and predictors of antibiotic-associated encephalopathy: a multicenter hospital-based study.

This study aimed to evaluate the incidence and likelihood of antibiotic-associated encephalopathy (AAE), comparing rates among the classes of antibiotics in monotherapy or in combination therapy. We also investigated the associations between the incidence of AAE and the glomerular filtration rate (GFR) and electroencephalogram features. Consecutive admissions that used any kind of antibiotics to treat infectious diseases were identified from six hospitals. We classified antibiotics according to three distinct pathophysiologic mechanisms and clinical subtypes. We searched for the incidence of AAE as the primary outcome. A total of 97,433 admission cases among 56,038 patients was identified. Cases that received type 1 antibiotics had significantly more frequent AAE compared to those that received type 2 antibiotics (adjusted odds ratio [OR], 2.62; 95% confidence interval [CI] 1.15-5.95; P = 0.021). Combined use of type 1 + 2 antibiotics was associated with a significantly higher incidence of AAE compared to the use of type 2 antibiotics alone (adjusted OR, 3.44; 95% CI 1.49-7.93; P = 0.004). Groups with GFR < 60 mL/min/1.73 m2 had significantly higher incidence rates of AAE compared to those with GFRs ≥ 90 mL/min/1.73 m2 among cases that received type 1 + 2 antibiotics. Detection of spike-and-wave or sharp-and-wave patterns on electroencephalogram was significantly more common in the combination therapy group. Combination use of antibiotics was associated with a higher incidence of AAE compared to monotherapy. The incidence of AAE significantly increased as renal function decreased, and epileptiform discharges were more likely to be detected in cases receiving combined antibiotics.

Guillain-Barré Syndrome After COVID-19 Infection in Korea: A Case Series.

Guillain-Barré syndrome (GBS) is an autoimmune-driven condition characterized by acute polyneuropathy, often emerging as a sequel to prior infections or vaccinations. This study presents the first reported cases of GBS emerging after the full recovery from coronavirus disease 2019 (COVID-19) infection in Korea. Despite experiencing mild acute COVID-19 symptoms, these patients faced substantial weakness attributed to GBS, significantly affecting their daily lives. The timely administration of intravenous immunoglobulin treatment halted the progression of symptoms, underscoring the critical importance of early intervention. These cases highlight the potential for neurological complications associated with COVID-19 and underscore the necessity for continuous monitoring and timely medical care.

Unilateral Myoclonus as an initial manifestation in Moyamoya disease with asymmetric vasculature.

Movement disorders have been identified as a rare early manifestation of the Moyamoya disease. Herein, we present a case of a 34-year-old man with a genetically confirmed Moyamoya disease who showed unilateral myoclonus as an initial manifestation. Neuroimaging studies showed prominent asymmetrically developed Moyamoya disease on the right hemisphere with near-complete loss of normal vessels while the left hemisphere was adjunctively fed with extension of posterior cerebral artery: uneven progression of vasculature. 99mTc-hexamethylpropylene amine oxime single-photon emission computed tomography demonstrated impaired vascular reserve. Electroencephalography showed occasional sharp waves on right temporal area. The phenomenon of this patient could be explained in the context of excitable cortex and hypoactive subcortical substrate that might imply putative contradictory neurobiology in Moyamoya disease.

Protein food avoidance behaviour among cancer patients - perspectives of nutrient intake and diet quality.

BACKGROUND AND OBJECTIVES: Previous study reported that high proportion of Chinese cancer patients practise food avoidance behaviour for fear of cancer recurrence. The present study aims at documenting the degree of food avoidance behaviours and its association with nutrient intake and diet quality among Chinese cancer patients. METHODS AND STUDY DESIGN: Cross-sectional face-to-face interviews were conducted with 245 patients suffering from nasopharyngeal and colorectal cancer to investigate their food avoidance behaviour. Participant's nutrient intake was assessed by 3-day diet record. Diet quality was measured by Diet Quality Index - International (DQI-I). RESULTS: As many as 86% cancer participants reported practicing food avoidance behaviours. The nutrients to which less than half of the participants met its daily requirement include vitamin D (0%), vitamin E (0.4%), calcium (7.8%), zinc (26.1%) and vitamin B1 (32.2%). Among all participants, only 47.8% met their daily energy requirement. Those reported having high degree of food avoidance behaviours are more likely to have low intake of protein, zinc and iron. However, there was no association between FAB and overall diet quality although the Variety subscale of DQI-I showed that food avoidance behaviours negatively link to participant's dietary sources of protein. CONCLUSIONS: Degree of practicing food avoidance behaviour is negatively associated with nutrients of animal origin, in particular protein. However, the overall diet quality was not affected by such. The study results provided important information to frontline clinical workers who are dealing with cancer patients practising non-mainstream diet.

Simultaneously Occurring Ischemic Stroke, Leg Artery Occlusion, and Pulmonary Embolism Induced by a Uterine Myoma.

OBJECTIVES: Paradoxical embolism from venous thrombosis through the patent foramen ovale is a rare but well-known cause of stroke in young adults. Here, we report a case of simultaneous middle cerebral artery infarction, multiple occlusions of the leg arteries, and pulmonary thromboembolism from the venous thrombus, all due to compression of the external iliac vein by a uterine leiomyoma. MATERIALS AND METHODS (CASE PRESENTATION): A 44-year-old woman presented with left hemiparesis and central-type left facial palsy. She denied a history of hypertension, diabetes mellitus, previous cerebral infarction, myocardial infarction, smoking, or oral contraceptive use. The patient recovered completely after injection of tissue plasminogen activator. Brain diffusion-weighted imaging showed an acute right middle cerebral artery infarction. Transcranial Doppler with saline agitation test revealed a right-to-left shunt, suggesting a patent foramen ovale. Chest computed tomography revealed multiple pulmonary thromboembolisms. Lower extremity sonography and lower extremity computed tomography revealed a multifocal thrombus in the major veins and arteries of the left leg. Moreover, a large uterine myoma compressing the left external iliac vein was noted on lower extremity computed tomography. RESULTS: After the treatment of pulmonary thromboembolism and venous thrombosis with rivaroxaban, surgical thrombectomy of the left popliteal artery, patent foramen ovale closure, and total hysterectomy were performed. Subsequently, she had no recurrent paradoxical embolism or pulmonary thromboembolism. CONCLUSION: Structural abnormalities in the pelvic cavity are not commonly suspected as stroke etiology. However, examination of the pelvic cavity is advisable in young female stroke patients with pulmonary thromboembolism or other paradoxical embolisms.

Recurrent Transient Neurological Deficit Due to Intracerebral Steal Phenomenon in Association with a Developmental Venous Anomaly.

We report a symptomatic developmental venous anomaly (DVA) not causing parenchymal abnormality to provide a pathophysiologic clue in patients with recurrent transient neurologic deficit. A 32-year-old male presented with recurrent transient motor aphasia and headache in the left fronto-temporal region for three years. The symptoms usually lasted for one hour. Brain computed tomography (CT) angiography and magnetic resonance imaging using gradient recalled echo showed a prominent penetrating vein at the left frontal periventricular region. Brain CT perfusion imaging performed during the symptoms revealed increased perfusion in the corresponding area with relatively decreased perfusion in the left fronto-temporal cortices. Digital subtraction angiography revealed collecting venous blood from the left septal and thalamostriate veins draining into the left cavernous sinus without early arteriovenous shunting. In this patient, an inciting incident might have led to imbalance of the venous flow surrounding the DVA, causing venous hypertension and the intracerebral steal phenomenon in the surrounding area. The relatively hypoperfused cortical area adjacent to the DVA could be considered the cause of the transient motor aphasia, while venous hypertension could be the cause of the headache.

Neuropsychiatric symptoms and striatal monoamine availability in early Parkinson's disease without dementia.

BACKGROUND AND OBJECTIVE: Neuropsychiatric symptoms are relatively common in Parkinson's disease (PD). Many studies have revealed that striatal monoamine availability is associated with specific neuropsychiatric symptoms. This study was aimed to investigate the association between comprehensive neuropsychiatric symptoms and striatal monoamine availability in patients with early PD without dementia. METHODS: A total of 156 newly diagnosed patients with PD without dementia were included. All patients' mental and behavioral problems were assessed with the 12-item Neuropsychiatric Inventory (NPI). They underwent positron emission tomography (PET) with 18F-N-(3-fluoropropyl)-2beta-carbon ethoxy-3beta-(4-iodophenyl) nortropane and brain magnetic resonance imaging (MRI). Patients were divided into no neuropsychiatric symptoms and neuropsychiatric symptoms groups according to total NPI score. After normalizing the PET images to spatially normalized MRI, regional standardized uptake value ratios (SUVRs) with a volume of interest template were analyzed for the two groups. RESULTS: Ninety-eight patients had more than one neuropsychiatric symptom. The SUVR of the thalamus in neuropsychiatric symptoms group was significantly lower than the SUVR in no neuropsychiatric symptoms group independent of age, sex, disease duration, or severity of motor symptoms. CONCLUSION: Patients with early PD who have neuropsychiatric symptoms had a lower monoamine availability in the thalamus than those with no neuropsychiatric symptoms. This finding suggests that decreased monoamine transporter availability in the thalamus may be an imaging biomarker of neuropsychiatric symptoms in patients with PD.

Long-term use of antibiotics and risk of type 2 diabetes in women: a prospective cohort study.

BACKGROUND: Accumulating evidence suggested that long-term antibiotic use may alter the gut microbiome, which has, in turn, been linked to type 2 diabetes. We undertook this study to investigate whether antibiotic use was associated with increased risk of type 2 diabetes. METHODS: This prospective cohort study included women free of diabetes, cardiovascular disease and cancer in the Nurses' Health Study (NHS 2008-2014) and NHS II (2009-2017). We evaluated the overall duration of antibiotics use in the past 4 years and subsequent diabetes risk with Cox proportional-hazards regression adjusting for demography, family history of diabetes and lifestyle factors. RESULTS: Pooled analyses of NHS and NHS II (2837 cases, 703 934 person-years) revealed that a longer duration of antibiotic use in the past 4 years was associated with higher risk of diabetes [Trend-coefficient = 0.09, 95% confidence interval (CI) 0.04 to 0.13]. Participants who received antibiotics treatment for a medium duration of 15 days to 2 months [hazard ratio (HR) 1.23, 95% CI 1.10 to 1.39] or long duration of >2 months (HR 1.20, 95% CI 1.02 to 1.38) had higher risk of type 2 diabetes as compared with non-users. Subgroup analyses suggested that the associations were unlikely to be modified by age, family history of diabetes, obesity, smoking, alcohol drinking, physical activity and overall diet quality. CONCLUSIONS: A longer duration of antibiotic use in recent years was associated with increased risk of type 2 diabetes in women. Physicians should exercise caution when prescribing antibiotics, particularly for long-term use.

What Happened to People with Non-Communicable Diseases during COVID-19: Implications of H-EDRM Policies.

People with existing non-communicable diseases (NCDs) are particularly vulnerable to health risks brought upon by emergencies and disasters, yet limited research has been conducted on disease management and the implications of Health-EDRM policies that address health vulnerabilities of people with NCDs during the COVID-19 pandemic. This paper reports the baseline findings of an anonymous, random, population-based, 6-month cohort study that aimed to examine the experiences of people with NCDs and their relevant self-care patterns during the COVID-19 pandemic. A total of 765 telephone interviews were completed from 22nd March to 1st April 2020 in Hong Kong, China. The dataset was representative of the population, with 18.4% of subjects reporting at least one NCD. Results showed that low household income and residence in government-subsidized housing were significant predictors for the subjects who experienced difficulty in managing during first 2 months of the pandemic (11% of the NCD patients). Of those on long-term NCD medication, 10% reported having less than one week's supply of medication. Targeted services for vulnerable groups during a pandemic should be explored to support NCD self-care.

Associations between dietary patterns and the risk of breast cancer: a systematic review and meta-analysis of observational studies.

BACKGROUND: Epidemiologic evidence suggests that certain dietary patterns were associated with breast cancer risk, but the results have been inconclusive. We assessed the associations between different dietary patterns and the risk of breast cancer by conducting a meta-analysis of observational studies. METHODS: Relevant articles were searched in PubMed, Embase, and Cochrane library databases through September 2017. Multivariable-adjusted relative risks (RRs) and 95% confidence intervals (CIs) comparing the highest and lowest categories of Western and prudent dietary patterns were combined by using the random-effects meta-analyses. RESULTS: We identified 32 eligible articles including 14 cohort and 18 case-control studies (34 Western and 35 prudent studies). The pooled analyses found that a Western dietary pattern was associated with a 14% increased risk (RR 1.14, 95% CI 1.02, 1.28), whereas a prudent dietary pattern was associated with an 18% reduced risk of breast cancer (RR 0.82, 95% CI 0.75, 0.89). In addition, sub-group analyses showed that the positive association between a Western dietary pattern and breast cancer risk was significant among postmenopausal (RR 1.20, 95% CI 1.06, 1.35), but not premenopausal women (RR 1.18, 95% CI 0.99, 1.40), and significant for hormone receptor-positive tumors (RR 1.18, 95% CI 1.04, 1.33), but not receptor-negative tumors (RR 0.97, 95% CI 0.83, 1.12). In contrast, the inverse association between a prudent dietary pattern and breast cancer was significant in premenopausal (RR 0.77, 95% CI 0.61, 0.98), but not postmenopausal women (RR 0.88, 95% CI 0.74, 1.03), and significant for both hormone receptor-positive and receptor-negative tumors. CONCLUSIONS: The results of the current meta-analysis suggest a possible increased risk of breast cancer associated with a Western dietary pattern and a reduced risk with a prudent dietary pattern. Large-scale cohort studies with a high quality need to be conducted to further confirm the findings of the current meta-analysis. As dietary patterns are modifiable, these findings may provide viable strategies for breast cancer prevention through changes in dietary intake.

Association between whole grain intake and breast cancer risk: a systematic review and meta-analysis of observational studies.

BACKGROUND: Epidemiological studies have found that high whole grain intake may be associated with a reduced risk of breast cancer. However, the evidence has not been consistent. We conducted a meta-analysis to quantitatively assess the association between whole grain intake and breast cancer risk. METHODS: Relevant observational studies were identified by searching PubMed, Embase, Cochrane library databases, and Google Scholar through April 2017. Summary relative risk (RR) estimates were calculated using random-effects meta-analysis. RESULTS: A total of 11 studies, including 4 cohort and 7 case-control studies and involving 131,151 participants and 11,589 breast cancer cases, were included in the current meta-analysis. The pooled RR of breast cancer for those with high versus low whole grain intake was 0.84 (95% confidence interval [CI]: 0.74 to 0.96, p = 0.009; I2 = 63.8%, p for heterogeneity = 0.002). Subgroup analysis by study design found a significant inverse association in the case-control studies (RR: 0.69; 95% CI: 0.56 to 0.87, p = 0.001; I2 = 58.2%, p for heterogeneity = 0.026), but not in the cohort studies (RR, 0.96; 95% CI: 0.82 to 1.14, p = 0.69; I2 = 66.7%, p for heterogeneity = 0.029). In addition, stratified analysis suggested that sample size could be a potential source of heterogeneity. CONCLUSIONS: Results of the current meta-analysis suggest that high intake of whole grains might be inversely associated with a reduced risk of breast cancer, and the inverse association was only observed in case-control but not cohort studies. More large-scale cohort studies are needed to confirm the inverse association observed.

Systematic Review of Guidelines on Managing Patients with Harmful Use of Alcohol in Primary Healthcare Settings.

AIM: To appraise existing alcohol guidelines for identifying and managing harmful alcohol use in primary healthcare settings. METHODS: Seven databases and 18 health organization or medical society websites were systematically searched from inception to 31 October 2016. Guidelines in English language, developed by a national or international medical specialty society, government or health organization, and containing recommendations for identifying and managing harmful use of alcohol in primary healthcare settings, were included. The Appraisal of Guidelines Research and Evaluation II (AGREE II) instrument was used to appraise the guidelines. RESULTS: Of the 970 literature identified, 17 were included for review, with 13 guidelines developed for use in Western countries and 4 for international use. The AGREE II scores ranged from 2.0 to 5.3, out of 7. Variations in terminology of harmful alcohol use were seen, with 'harmful drinking' and 'problem drinking' being mostly used. All guidelines were in favor of screening and brief interventions due to their effectiveness and cost-effectiveness. Potential benefits and costs of applying screening and brief interventions were found, but there was a lack of evidence for long-term effects or specific populations. CONCLUSIONS: All 17 guidelines recommended screening and brief interventions due to its associated health and financial benefits. Policy makers are highly encouraged to integrate these practices into primary healthcare settings taking the drinking status, culture and resources into account. SHORT SUMMARY: Screening and brief interventions were recommended by all 17 guidelines on managing patients with harmful use of alcohol in primary healthcare settings. Policy makers and healthcare practitioners are highly encouraged to implement these recommendations.

A hybrid seasonal prediction model for tuberculosis incidence in China.

BACKGROUND: Tuberculosis (TB) is a serious public health issue in developing countries. Early prediction of TB epidemic is very important for its control and intervention. We aimed to develop an appropriate model for predicting TB epidemics and analyze its seasonality in China. METHODS: Data of monthly TB incidence cases from January 2005 to December 2011 were obtained from the Ministry of Health, China. A seasonal autoregressive integrated moving average (SARIMA) model and a hybrid model which combined the SARIMA model and a generalized regression neural network model were used to fit the data from 2005 to 2010. Simulation performance parameters of mean square error (MSE), mean absolute error (MAE) and mean absolute percentage error (MAPE) were used to compare the goodness-of-fit between these two models. Data from 2011 TB incidence data was used to validate the chosen model. RESULTS: Although both two models could reasonably forecast the incidence of TB, the hybrid model demonstrated better goodness-of-fit than the SARIMA model. For the hybrid model, the MSE, MAE and MAPE were 38969150, 3406.593 and 0.030, respectively. For the SARIMA model, the corresponding figures were 161835310, 8781.971 and 0.076, respectively. The seasonal trend of TB incidence is predicted to have lower monthly incidence in January and February and higher incidence from March to June. CONCLUSIONS: The hybrid model showed better TB incidence forecasting than the SARIMA model. There is an obvious seasonal trend of TB incidence in China that differed from other countries.

Maternal understanding of commercial cord blood storage for their offspring - a survey among pregnant women in Hong Kong.

OBJECTIVE: To assess the knowledge on commercial cord blood banking (CCBB) among pregnant women. DESIGN: Cross-sectional survey. Setting. Antenatal clinics of two major public maternity units in Hong Kong. POPULATION: Pregnant women. METHODS: Self-administered questionnaire. MAIN OUTCOME MEASURES: The survey explored knowledge about the use of self-stored umbilical cord blood (UCB) stem cells and attitude towards CCBB. RESULTS: Of the 2,000 women recruited, 1 866 (93.3%) completed the questionnaire. The majority (78.2%) had no idea that there was the chance of using self-stored stem cells. Moreover, most of the respondents were unclear about which diseases other than leukemia are amenable to treatment with UCB stem cells in general. Only 20.3% of women knew that stem cells are available from the Red Cross in case their children need hematopoietic cell transplantation. CONCLUSIONS: The results of this study revealed inadequate knowledge on UCB stem cell banking and its applications among most of our pregnant women. The government and clinicians should combine efforts to provide accurate information on utilization of UCB stem cells during antenatal care.
