Correlation between inflammatory markers with cognitive function in coronavirus disease‐19 (COVID‐19) patients

AbstractBackgroundCoronavirus disease‐2019 (COVID‐19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) and remains an ongoing global pandemic. Although it mainly affects the respiratory system, its manifestation in other organs including nervous system has been increasingly recognized. Previous studies have shown the association between several inflammatory markers with disease severity and mortality in COVID‐19 patients but their association with cognitive function remains unclear. This study aimed to determine the correlation between inflammatory markers with cognitive function in COVID‐19 patients.MethodThis was a cross‐sectional study involving COVID‐19 patients during admission using consecutive sampling method in Adam Malik General Hospital Medan Indonesia. Cognitive function was assessed in several domains using Forward Digit Span (FDS), Backward Digit Span (BDS), and Trail Making Tests A and B (TMT‐A and TMT‐B), to assess attention, working memory and executive function, respectively. We measured neutrophil to lymphocyte ratio (NLR,) C‐reactive protein (CRP), D‐dimer, and ferritin serum levels as inflammatory markers.ResultThis study involved 40 COVID‐19 patients consisting of 13 (32.5%) males and 27 (67.5%) females, the median age value of the patients was 39.5(19‐65) years. We found that higher ferritin level was correlated with worse FDS and BDS scores (r = ‐0.365 p = 0.020 and r = ‐0.408 p = 0.009, respectively)and that d‐dimer level was significantly correlated with worse BDS score (r = ‐0.369 p = 0.019). Higher D‐dimer and ferritin levels were also significantly correlated with longer time of completion of TMT‐B (r = 0.363 p = 0.022 and r = 0.433 p = 0.005, respectively) and higher ferritin level was also correlated with longer time of completion of TMT‐A (r = 0.438 p = 0.005). There were no significant correlation between NLR and CRP level with cognitive function.ConclusionHigher inflammatory markers were correlated with attention, working memory and executive function in COVID‐19 patients.

Profile of Hippocampal Volume of Adults in North Sumatera

BACKGROUND: Hippocampus is a brain region that includes in the limbic lobe. It is formed by two groups of neurons that look such as letter C, which were facing each other – dentate gyrus and Ammon’s horn and played an essential role in the development of memory. AIM: The objective of this study is to find the volume of the right and left hippocampal volume and the measurement of the total volume. To the best of our knowledge, this is the first study in Indonesia that measures the hippocampal volume of healthy adults. METHODS: We collected 54 subjects of healthy adults in Medan Indonesia, with the inclusion criteria: Age 15–40 years, cooperative and willing to be interviewed, and did not have a family history of mental disorders. Exclusion criteria for the control group were excluded from the study: Having a history of previous mental disorders and a general medical condition that affected brain structure, and obesity. We used MINI ICD-10 structured clinical interview to rule out the mental disorders. Hippocampal measurement was done by manual segmentation using AnalyzePro software that was developed by Mayo Clinic and followed the protocol of manual segmentation of hippocampal measurement from the Alzheimer’s Disease Neuroimaging Initiative: Magnetic resonance imaging methods. RESULTS: We found that the total hippocampal volume was 3979.77 ± 678.51 mm3. COCLUSION: Our findings of hippocampal volume were smaller than other Asian people. Few conditions had been thought related to it, that is, chronic stress exposure inducing prolonged hypothalamic-pituitary-adrenal axis activation that leads to loss of hippocampal neurons and neural level conditions resulting from gene-environment interaction. This smaller hippocampal volume can also predict verbal memory function in the future.

Correlation of Cystatin-c with Albumin Creatinine Ratio for the Diagnosis of Diabetic Nephropathy in Patients with Type 2 Diabetes: A Cross-sectional Study in Medan Indonesia

BACKGROUND: Diabetic nephropathy (ND) is one of the main complications of chronic microvascular diabetes mellitus (DM) and the leading cause of the end-stage renal disease (ESRD), accounting for nearly half of all ND cases with ESRD incidence in developed countries. Recently, cystatin C serum has been considered as a new biomarker for the diagnosis of kidney damage. Cystatin-C is an appropriate marker for GFR measurement because it is not affected by age, weight, gender, and protein intake. Early detection of abnormal renal function is essential to slow progression to a further stage of nephropathy or the final stage of kidney disease. AIM: The aim of the study was to analyze the correlation between cystatin-C and ACR to early detection of nephropathy complications. MATERIALS AND METHODS: This study uses an observational analytical research design with a cross-sectional approach. The research was conducted on patients with type 2 diabetes mellitus (T2DM) who were visiting the primary health service in Medan that met the inclusion and exclusion criteria. The sample count was 89 respondents. The sampling method is done through consecutive sampling. The source of this research data is primary data, including the results of cystatin-c examination and albumin. Data analysis used Spearman correlation using SPSS for Windows software. RESULTS: There was a significant relationship between cystatin-C levels and albuminuria (p<0.05). CONCLUSION: Diabetic nephropathy is a clinical syndrome characterized by persistent albuminuria and progressive decline of renal function, cystatin-C and albuminuria levels can be used as early detection of nephropathy complications.

The arrangement of Hamdan Sukaraja Slum Settlements in Medan Indonesia, through the concept of affordable vertical village

Initially, the city of Medan consisted of villages, often called urban villages, which evolved to form cities. Sukaraja and Hamdan villages are old villages that are part of the Sultanate of Deli and reflect the sociocultural character of the local people of Medan. Now, these villages have grown to the banks of the Deli River. The residents choose to live in riverbank areas that are not well-designed and create unhealthy slums that have social, economic, and cultural problems. These villages will be displaced soon by the discourse of the toll project in the city of Medan on the Deli River. This paper aims to analyze and provide solutions to the problems of the development of slums in the Deli River area. Both environmental, architectural, social, and economic issues of the population. Based on data analysis, the people of Hamdan and Sukaraja villages need livable housing at an affordable cost and can support the community’s economy. This study recommends a vertical village design with an Ecological Architecture approach and integrated with sustainable economic systems. The vertical village design also accommodates the economic empowerment of Sukaraja and Hamdan villagers by developing and integrating businesses that have grown previously in this village.

Association of Vitamin D Level and Nerve Conduction Study Parameters with Cognitive Function in Diabetic Neuropathy Patients

BACKGROUND: Type 2 diabetes mellitus (T2DM) and its major long-term complication, diabetic polyneuropathy (DPN), continue to be a major global health problem and are important contributors of significant disability worldwide. Vitamin D plays a significant role in their pathogenesis as well as in the development of dementia in non-diabetic patients. Nevertheless, the role of Vitamin D in the development of cognitive impairment in DPN patients has not yet been extensively studied. AIM: We aimed to investigate the association between Vitamin D level and cognitive function in DPN patients and to evaluate several potential contributor factors to cognition, including demographic factors, glycemic control, and nerve conduction study (NCS) parameters. METHODS: Thirty-one DPN patients were included in this cross-sectional study. Patients were recruited from the outpatient endocrinology and neurology clinic of Haji Adam Malik General Hospital Medan Indonesia. We used the diabetic neuropathy examination (DNE) scale, diabetic neuropathy symptom (DNS) scale, and NCS to determine the presence and severity of the neuropathy. We measured the levels of Vitamin D, random blood sugar, and glycated hemoglobin (HbA1c). Cognitive function was assessed using the Indonesian version of Montreal Cognitive Assessment (MoCA-INA), trail making test A and B (TMT A and TMT B), and verbal fluency test. RESULTS: Most of the patients were female (80.6%), with a mean age of 55.71 ± 8.34 years. The proportion of patients with abnormal cognitive function was higher than cognitively unimpaired patients. The mean of MoCA-INA score and level of Vitamin D was lower than normal, 23.32 ± 3.00 and 24.91 ± 13.59 ng/ml, respectively. Using the Pearson correlation test, we did not find any significant association of Vitamin D level, NCS parameters, and other clinical characteristics with global cognitive function. Age and level of education were significantly associated with MoCA-INA score. Blood sugar level was significantly higher in patients with normal TMT-A and TMT-B tests compared to patients with abnormal results. CONCLUSION: Vitamin D and NCS parameters are not associated with cognitive function. Of the demographic and clinical characteristics, a significant association exists between age, level of education, and blood sugar level and cognition. This might suggest the complexity underlying cognitive impairment in T2DM patients.
