The Impact of Light Touch and Pin Prick on Functional Outcomes in Patients with Traumatic Spinal Cord Injury.

A spinal cord injury (SCI) can cause severe lifelong functional disability and profoundly affect an individual's daily life. We investigated the prediction of patients' post-SCI functional outcomes by evaluating sensory scores rather than motor scores, as the latter's association with functional outcomes is well established. We examined patients' responses to a light touch (LT) and pin prick (PP) at admission and the response data's usefulness as predictors of functional outcomes (i.e., ability to perform activities of daily living) at discharge. This exploratory observational study used data from the Japanese National Spinal Cord Injury Database (SCI-J). Data from 3,676 patients who met the inclusion criteria and were admitted for an SCI between 1997 and 2020 were analyzed. The motor score of the Functional Independence Measure (mFIM) at discharge was used as an index of functional outcome. A multiple regression analysis revealed that the mFIM was associated with both the LT response (ß=0.07 (0.01), p<0.001) and the PP response (ß=0.07 (0.01), p<0.001) at admission. The false discovery rate log-worth values for LT and PP were 6.6 and 8.5, respectively. Our findings demonstrate that LT and PP scores at admission can help predict patients' functional outcomes after an SCI, although the magnitude of their contributions is not high.

COVID-19 fatality and DALYs, and associated metabolic disorders and ambient air pollutants in pre-Omicron era of the pandemic: an international comparative study.

BACKGROUND: Air pollution and a number of metabolic disorders have been reported to increase the risk of severe COVID-19 outcomes. This study explored the association between severe COVID-19 outcomes, metabolic disorders and environmental air pollutants, at regional level, across 38 countries. METHODS: We conducted an ecological study using COVID-19 data related to countries of the Organization for Economic Cooperation and Development (OECD), with an estimated population of 1.4 billion. They were divided into 3 regions: 1. Europe & Middle east; 2. Americas (north, central & south America); 3. East-Asia & West Pacific. The outcome variables were: COVID-19 case-fatality rate (CFR) and disability-adjusted life years (DALYs) at regional level. Freely accessible datasets related to regional DALYs, demographics and other environmental pollutants were obtained from OECD, WHO and the World in Data websites. Generalized linear model (GLM) was performed to determine the regional determinants of COVID-19 CFR and DALYs using the aggregate epidemiologic data (Dec. 2019-Dec. 2021). RESULTS: Overall cumulative deaths were 65,000 per million, for mean CFR and DALYs of 1.31 (1.2)% and 17.35 (2.3) years, respectively. Globally, GLM analysis with adjustment for elderly population rate, showed that COVID-19 CFR was positively associated with atmospheric PM2.5 level (beta = 0.64(0.0), 95%CI: 0.06-1.35; p < 0.05), diabetes prevalence (beta = 0.26(0.1), 95%CI: 0.12-0.41; p < 0.001). For COVID-19 DALYs, positive associations were observed with atmospheric NOx level (beta = 0.06(0.0), 95%CI: 0.02-0.82; p < 0.05) and diabetes prevalence (beta = 0.32(0.2), 95%CI: 0.04-0.69; p < 0.05). At regional level, adjusted GLM analysis showed that COVID-19 CFR was associated with atmospheric PM2.5 level in the Americas and East-Asia & Western Pacific region; it was associated with diabetes prevalence for countries of Europe & Middle east and East-Asia & Western Pacific region. Furthermore, COVID-19 DALYs were positively associated with atmospheric PM2.5 and diabetes prevalence for countries of the Americas only. CONCLUSION: These findings confirm that diabetes and air pollution increase the risk of disability and fatality due to COVID-19, with disparities in terms of their impact. They suggest that efficient preventive and management programs for diabetes and air pollution countermeasures would have curtailed severe COVID-19 outcome rates.

Tumor-to-blood pool ratio of 18F-fluorodeoxyglucose-positron emission tomography's standardized uptake value as a useful parameter indicating malignant transformation in pancreatic branch-duct intraductal papillary mucinous neoplasm compared to the international Fukuoka guidelines: a retrospective cohort study from surgical resections.

BACKGROUND: Identifying malignant transformation in pancreatic branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) remains challenging, but the standardized uptake value (SUV) obtained from 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET)/CT has the potential to become a valuable parameter for differentiation. This study aimed to assess the effectiveness of SUV of FDG-PET/CT in distinguishing low-grade dysplasia (LGD), high-grade dysplasia (HGD), and intraductal papillary mucinous carcinoma (IPMC) within BD-IPMNs. METHODS: We assessed 58 patients with confirmed BD-IPMN undergoing surgery between 2008 and 2022. Receiver operating characteristic curves were plotted using the tumor-to-blood pool ratio (TBR) of FDG-PET/CT in two scenarios: one considering HGD + IPMC as positive and the other considering only IPMC as positive. RESULTS: In the cohort of 58 cases, there were 39 females, and the median age was 71 years. The median TBR value was 1.45 (range, 0.35-25.44). The TBRs exhibited a significant correlation with each histopathology (p < 0.001). Furthermore, in the multivariate analysis, TBR was independently significant in both scenarios, with HGD + IPMC defined as malignant (p = 0.001) and with only IPMC defined as malignant (p = 0.024). CONCLUSIONS: TBR might have the potential to serve as a valuable parameter for indicating malignant transformation in pancreatic BD-IPMNs.

The Association between Preoperative Blood Pressure Elevations and Postoperative Adverse Outcomes after Non-cardiac Surgery: A Single-center Retrospective Observational Study.

Blood pressure (BP) often rises before surgery. This study investigated whether BP elevation immediately before surgery was associated with adverse outcomes. Medical records of 11,732 patients (average age: 61 years; male: 47.4%) who underwent non-cardiac elective inpatient surgery under general anesthesia at Kagawa University Hospital between January 2011 and June 2019 were reviewed. Differences between the first BP values measured on the day before surgery and the first BP values in the operating room were defined as Δ systolic BP (ΔSBP) and Δ diastolic BP (ΔDBP). The relationships between ΔSBP/ΔDBP and 30-day mortality, 30-day readmission, and over-the-standard length of hospital stay (OSLOS) were assessed. OSLOS was defined as a hospital stay longer than mean+2 standard deviations and was calculated using the Japanese Diagnosis Procedure Combination data. In univariate analysis, the differences in ΔSBP and ΔDBP between the OSLOS and standard LOS groups were both 2 mmHg. In multivariate logistic regression analysis, only ΔDBP was associated with OSLOS. The adjusted odds ratio (95% confidence interval) for the largest quartile was 1.31 (1.02-1.69) (p<0.05). ΔDBP was associated with OSLOS; however, there may be little need to worry about large ΔSBPs and ΔDBPs in clinical practice.

Country-level and regional COVID-19 burden and determinants across OECD member states and partner countries.

BACKGROUND: COVID-19 pandemic is tremendously impacted by socioeconomic and health determinants worldwide. This study aimed to determine factors associated with COVID-19 fatality among member states and partner countries of the Organization for Economic Cooperation and Development (OECD). METHODS: An ecological study was conducted using COVID-19 data of 48 countries for the period between 31 December 2019-31 December 2021. The outcome variables were COVID-19 case fatality rate (CFR) and years of life lost to COVID-19 (YLLs). Countries' sociodemographics and COVID-19-related data were extracted from OECD website, Our World in Data, John Hopkins Coronavirus Resource Center, Economist Intelligence Unit (EIU) and WHO. RESULTS: In the first year of the pandemic (December 2019-January 2021), highest CFR was observed in Mexico, 8.51%, followed by China, 5.17% and Bulgaria, 4.12%), and highest YLLs was observed in Mexico, 2,055 per 100,000. At regional level, highest CFR was observed in North & central America, 4.25 (3.71) %, followed by South America (2.5 (0.1) %); whereas highest YLLs was observed in South America region 1457.5 (274.8) per 100,000, followed by North & central America, 1207.3 (908.1) per 100,000. As of 31 December 2021, Mexico (7.52%) and Bulgaria (4.78%) had highest CFR; on the other hand, highest YLLs was observed in England, 26.5 per 1,000, followed by the United States, 25.9 per 1,000. At regional level, highest CFR (3.37(3.19) %) and YLLs (16.7 (13) per 1,000) were both observed in North & central America. Globally, the analysis of the 2-year cumulative data showed inverse correlation between CFR and nurse per 10,000 (R = -0.48; p < 0.05) and GDP per capita (R = -0.54; p < 0.001), whereas positive correlation was observed between YLLs and elderly population rate (R = 0.66; p < 0.05) and overweight/obese population rates (R = 0.55; p < 0.05). CONCLUSION: This study provides insights on COVID-19 burden among OECD states and partner countries. GDP per capita, overweight/obesity and the rate of elderly population emerged as major social and health determinants of COVID-19 related burden and fatality. Findings suggest that a robust economy and interventions designed to promote healthy longevity and prevent weight gain in at-risk individuals might reduce COVID-19 burden and fatality among OECD states and partner countries.

Malaria rapid diagnostic test (HRP2/pLDH) positivity, incidence, care accessibility and impact of community WASH Action programme in DR Congo: mixed method study involving 625 households.

BACKGROUND: Malaria is one of the most prevalent and deadliest illnesses in sub-Saharan Africa. Despite recent gains made towards its control, many African countries still have endemic malaria transmission. This study aimed to assess malaria burden at household level in Kongo central province, Democratic Republic of Congo (DRC), and the impact of community participatory Water, Sanitation and Hygiene (WASH) Action programme. METHODS: Mixed method research was conducted in two semi-rural towns, Mbanza-Ngungu (a WASH action site) and Kasangulu (a WASH control site) in DRC between 1 January 2017 through March 2018, involving 625 households (3,712 household members). Baseline and post-intervention malaria surveys were conducted with the use of World Bank/WHO Malaria Indicator Questionnaire. An action research consisting of a six-month study was carried out which comprised two interventions: a community participatory WASH action programme aiming at eliminating mosquito breeding areas in the residential environment and a community anti-malaria education campaign. The latter was implemented at both study sites. In addition, baseline and post-intervention malaria rapid diagnostic test (RDT) was performed among the respondents. Furthermore, a six-month hospital-based epidemiological study was conducted at selected referral hospitals at each site from 1 January through June 2017 to determine malaria trend. RESULTS: Long-lasting insecticide-treated net (LLIN) was the most commonly used preventive measure (55%); 24% of households did not use any measures. Baseline malaria survey showed that 96% of respondents (heads of households) reported at least one episode occurring in the previous six months; of them only 66.5% received malaria care at a health setting. In the Action Research, mean incident household malaria cases decreased significantly at WASH action site (2.3 ± 2.2 cases vs. 1.2 ± 0.7 cases, respectively; p < 0.05), whereas it remained unchanged at the Control site. Similar findings were observed with RDT results. Data collected from referral hospitals showed high malaria incidence rate, 67.4%. Low household income (ORa = 2.37; 95%CI: 1.05-3.12; p < 0.05), proximity to high risk area for malaria (ORa = 5.13; 95%CI: 2-29-8.07; p < 0.001), poor WASH (ORa = 4.10; 95%CI: 2.11-7.08; p < 0.001) were predictors of household malaria. CONCLUSION: This research showed high prevalence of positive malaria RDT among the responders and high household malaria incidence, which were reduced by a 6-month WASH intervention. DRC government should scale up malaria control strategy by integrating efficient indoor and outdoor preventive measures and improve malaria care accessibility.

Behavior problems and dysfunctional parenting: Cross-sectional study in Japan.

BACKGROUND: The Japanese government has established a law encouraging early detection and treatment of developmental disorders in children. Child behavior problems (CBP) tend to be recognized at school as a result of developmental disorders. The aim of this study was to identify factors associated with CBP in Japan. We hypothesized that factors other than developmental disorders are important in explaining CBP. METHODS: The study was conducted between February and March 2015. Parents of 3,515 children aged 2-5 years attending one of 34 public nursery schools in Takamatsu, Kagawa, Japan received self-administered questionnaires addressing parental socioeconomic factors, mental health, parenting style (i.e. hostile, overreactive, or lax), developmental disorders in children, and CBP. A multiple regression analysis was applied to explore associations between CBP and possible factors. RESULTS: Overall, 1,410 mothers were eligible to participate in the study. Children diagnosed with developmental disorders accounted for 7.8% of the sample, while on the Eyberg Child Behavior Inventory 17% of children had behavior problems needing clinical intervention. After adjustment for confounding factors, as well as for the diagnosis of developmental disorders, poor mental status and all three dysfunctional parenting styles had strong associations with CBP, and hostile, overreactive, and lax parenting had standardized ß-values (ß) of 0.29, 0.28, and 0.15, respectively (P < 0.01). A problematic relationship between the parents was also significantly associated with CBP (ß = -0.29, P < 0.01). CONCLUSION: When CBP are identified, parenting skills, mental health status and parental relationships should be considered along with the possibility of developmental disorders in the development of interventions.

Quality of dying and death desired by residents of Kagawa Prefecture, Japan: a qualitative study.

BACKGROUND: Achieving a desirable death is an urgent aging-related problem in Japan. However, measures of the quality of death and dying in Japan are lacking. This study aimed to identify components of a desirable death in the residents of Kagawa prefecture, Japan, through focus group interviews. METHODS: A group interview was conducted with 30 residents aged 20-80 (Mage = 50.9, SD = 22.1 years; 43.3% ≥ 65 years; 40.0% unemployed) who had experienced the death of a closely associated person. Participants were grouped into four generations with diverse characteristics (e.g., age, sex, occupation). The interview lasted 1-2 h and involved one interviewer, one observer, and one recorder. The interview theme was "What is a desirable death?" Participants were asked "What do you want to achieve before you die?" or "What would a close friend want to experience when death is near?" We then extracted important items related to "desirable death" using serialization and observation records, while also consulting three analysts. The analysis results of the four generations were ultimately integrated into final categories. RESULTS: The most common experience of a familiar death was that of parents, followed by grandparents. Half of participants had witnessed the death. Through category analysis, eight important categories related to desirable death were ultimately extracted. Nine items were identified as common to all generations. While the elderly generation had wide-ranging opinions, the younger generations' opinions tended to concentrate on satisfaction with life and family relations. CONCLUSION: Eight concepts were extracted as important factors of a desirable death from the residents of Kagawa prefecture, Japan.

Long-term effects of low-intensity training with slow movement on motor function of elderly patients: a prospective observational study.

BACKGROUND: Slow-motion training, which comprises exercising using extremely slow-movements, yields a training effect like that of high-intensity training, even when the applied load is small. We developed a slow-training exercise program that allows elderly people to safely use their own body weight without a machine. Previously, it was confirmed that functional gait and lower limb muscle strength were improved by low-intensity training using bodyweight training for 3 months. This study evaluated the long-term effects of low-intensity training using body weight with slow-movements on the motor function of frail, elderly patients. METHODS: Ninety-six elderly men and women aged 65 years or older whose level of nursing care was classified as either support required (1 and 2) or long-term care required (care levels 1 and 2) volunteered to participate. Two facilities were used. Participants at the first facility used low-intensity training using body weight with slow-movements (low-stress training [LST] group, n = 65), and participants at another facility used machine training (MT group, n = 31). Exercise interventions were conducted for 12 months, once or twice per week, depending on the required level of nursing care. Changes in motor function were examined. RESULTS: Post-intervention measurements based on the results of the chair-stand test after 12 months showed significant improvements from pre-intervention levels (P < 0.0001) in the LST group and MT group. Although the ability of performing the Timed Up & Go test and the ability to stand on one leg with eyes open improved in both groups, no significant change was observed. When changes after 12 months were compared between the two groups, no significant difference was observed for any variables. CONCLUSIONS: Slow body weight training for 12 months without a machine improved the lower limb muscle strength. Therefore, it could have the same effects as training using a machine.

Cost of illness of non-alcoholic liver cirrhosis in Japan: A time trend analysis and future projections.

AIM: Liver cirrhosis is a preneoplastic condition to hepatocellular carcinoma that is an important worldwide public health concern, and its economic burden has been estimated in some countries. The objective of this study was to estimate and predict the cost of illness (COI) associated with non-alcoholic liver cirrhosis in Japan. METHODS: Using a COI method on available data from government statistics, we estimated the economic burden in 3-year intervals from 1996 to 2014. We then predicted the COI in 3-year intervals from 2017 to 2029 using fixed and variable model estimations. With fixed model estimation, only the estimated future population was used as a variable. Variable model estimation considered the time trends of health-related indicators throughout the past 18 years. RESULTS: The estimated COI of non-alcoholic liver cirrhosis was ¥208.1bn in 2014. The COI of non-alcoholic liver cirrhosis had a downward trend from 1996 to 2014. The predicted future COI of non-alcoholic liver cirrhosis was ¥144.3-210.5bn, ¥106.0-213.8bn, ¥88.6-213.4bn, ¥76.7-215.5bn, and ¥66.4-214.3bn in 2017, 2020, 2023, 2026, and 2029, respectively. CONCLUSIONS: The results of this study suggest that the COI of non-alcoholic liver cirrhosis in Japan has steadily decreased and will continue to decrease. Treatment of patients with hepatitis C virus infection with newly introduced technologies has high therapeutic effectiveness, which will affect the future prevalence of non-alcoholic liver cirrhosis. When interpreting the results of long-term estimation, it should be noted that the results of this study were based on present conditions.

Effects of low-intensity bodyweight training with slow movement on motor function in frail elderly patients: a prospective observational study.

BACKGROUND: Slow-motion training, an exercise marked by extremely slow movements, yields a training effect like that of a highly intense training, even when the applied load is small. This study evaluated the effects of low-intensity bodyweight training with slow movement on motor function in frail, elderly patients. METHODS: Ninety-seven elderly men and women aged 65 years or older, whose level of nursing care was classified as either support required (1 and 2) or long-term care required (care level 1 and 2), volunteered to participate. Two facilities were used. Participants in the first facility used low-intensity bodyweight training with slow movement (the LST group, n = 65), and participants in another facility used machine training (the control group, n = 31). Exercises were conducted for 3 months, once or twice a week, depending on the required level of nursing care. Changes in motor function were examined. RESULTS: Post-exercise measurements showed significant improvements from the pre-exercise levels after 3 months, based on the results of the Timed Up and Go test (p = 0.0263) and chair-stand test (p = 0.0016) in the low-intensity exercise with slow movement and tonic force generation (LST) group. Although the ability to stand on one leg with eyes open tended to improve, no significant change was found (p = 0.0964). CONCLUSIONS: We confirmed that carrying out LST bodyweight training for 3 months led to improvements in ambulatory function and lower-limb muscle strength. In this way, it is possible that LST training performed by holding a bar or by staying seated on a chair contributes to improved motor function in elderly patients within a short time.

Revisiting Microsurgical Distal Bypass for Critical Limb Ischemia.

Background The purpose of this study was to investigate the efficacy of introducing microsurgical techniques to distal bypass surgery for critical limb ischemia. Methods Datasets of 83 consecutive microsurgical distal bypasses in a multicenter (SKY) study were compared with the results of the PREVENT III (PIII) study regarding the following: (1) patients' characteristics, (2) clinical severity according to the PIII risk score, (3) conduits and procedures for revascularization, (4) proximal and distal anastomosis sites, and (5) primary patency and amputation-free survival (AFS) rates at 1 year. Results The high-risk group in the SKY study was larger compared with that in the PIII study (37 vs. 9%, respectively; p < 0.0001). Although all patients underwent revascularization in the perimalleolar region (100 vs. 65.1%, respectively; p < 0.0001), the primary patency rate at 1 year was 71.8%, compared with 59.9% in the PIII study (p = 0.0227). The AFS rate at 1 year was not significantly different between the SKY and PIII studies (80.6 vs. 75.1%, respectively; p = 0.189); however, there was a significant difference between the high-risk subsets of each group: 74.1% in the SKY study and 45% in the PIII study (p < 0.0001). Conclusions Our data demonstrated that microsurgical distal bypass is an effective and durable procedure, especially for high-risk patients. We believe that microsurgical techniques should be considered for distal bypass to optimize the treatment of ischemic limbs with severe peripheral artery disease.

A Comparison of Sleep Duration Accuracy Between Questionnaire and Accelerometer in Middle Childhood.

Purpose Healthy sleep is vital to children's well-being, and assessing sleep efficiently and accurately can help understand children's lifestyles. Due to the difficulty in objectively measuring sleep duration using wearable sensors in large-scale surveys of children, self-administered questionnaires are often used in Japan; however, their accuracy is uncertain. We evaluated and compared the accuracy of questionnaire-based sleep times to those of wearable sensors. Methods This observational study was conducted between November 2019 and January 2020. A self-administered questionnaire on lifestyle habits and ActiGraph GT3X+ (ActiGraph, Inc., Pensacola, USA) accelerometer data were collected from 40 fourth-grade elementary school students in Kagawa Prefecture, Japan. We analyzed measurements for 256 days out of 280 days (40 persons × 7 days) after excluding days when the rate of wearing the accelerometer was < 90%. Results The median sleep duration per accelerometry was 453 minutes, and the median time in bed was 519 minutes. Questionnaire-based time in bed was 11 minutes longer, with relatively high inter-individual variability. The difference in bedtime was 26 minutes earlier, and wake-up time was 12 minutes earlier for the questionnaire. The average sleep efficiency was 87.4%, and one-third of the children had sleep efficiency < 85%. Conclusion The difference in sleep duration by questionnaire compared to accelerometry was approximately 10 minutes, suggesting the questionnaire may determine sleep duration with accuracy.

Pre-existing arteriosclerotic intimal thickening in living-donor kidneys reflects allograft function.

BACKGROUND: Donor shortage is a serious problem worldwide and it is now debated whether kidneys from marginal donors are suitable for renal transplantation. Recent studies have shown that the findings of preimplantation kidney biopsy are useful to evaluate vasculopathy in the donated kidney, and may predict transplant outcomes in deceased- donor kidney transplantation. However, few studies have focused on the pathological findings of preimplantation biopsy in living-donor kidney transplantation. Therefore, we investigated whether arteriosclerotic vasculopathy in living-donor kidneys at the time of transplantation predicts the recipient's kidney function (allograft function) later in life. METHODS: We retrospectively analyzed 75 consecutive adult living-donor kidney transplants performed at Kagawa University Hospital. Renal arteriosclerotic vasculopathy was defined according to the presence of fibrous intimal thickening in the interlobular artery. RESULTS: Forty-one kidneys exhibited mild arteriosclerotic vasculopathy on preimplantation kidney biopsies. The decreases in estimated glomerular filtration rate after donation were similar in donors with or without renal arteriosclerotic vasculopathy. Pre-existing arteriosclerotic vasculopathy did not affect graft survival rate, patient survival rate or the incidence of complications. Recipients of kidneys with arteriosclerotic vasculopathy had lower allograft function at 1 and 3 years after transplantation than the recipients of arteriosclerosis-free kidneys with or without donor hypertension. In multivariate analysis, fibrous intimal thickening on preimplantation biopsy was predictive of reduced allograft function at 1 year after transplantation. CONCLUSIONS: The present study demonstrated that mild arteriosclerotic vasculopathy in the donated kidney is an important pathological factor that reflects future impaired function of renal allografts from marginal donors.

The number of physicians is related to the number of nighttime emergency surgeries in Japan: An ecological study.

PURPOSE: Increasing the number of physicians per population may improve the quality of medical services, but there are few reports on this aspect in the field of surgery. This study aimed to examine whether the number of physicians is associated with the number of nighttime emergency surgeries, which may be one of the indicators of the quality of medical services in the field of surgery. METHODS: This was a prefecture-based ecological study utilizing open data from Japanese government surveys conducted between 2015 and 2019. The relationship between the number of physicians and the number of nighttime emergency surgeries in 47 prefectures of Japan was evaluated by correlation analysis and panel data regression analysis. The correlation analysis was conducted between the number of physicians per 100,000 population and the number of nighttime emergency surgeries per 100,000 population per year in each prefecture in Japan. In the panel data regression analysis, panel data of the prefectures in Japan from 2015 to 2019 were created. We evaluated whether the number of physicians was related to the number of nighttime emergency surgeries, independent of the number of acute care beds per 100,000 population, population density, and the elderly population ratio. RESULTS: From the correlation analysis, the correlation coefficient between the number of physicians per 100,000 population and the number of nighttime emergency surgeries per 100,000 population was 0.533 (P < 0.001). In the panel data regression analysis, there was a significant association between the number of physicians per 100,000 population and the number of nighttime emergency surgeries per 100,000 population (P < 0.001). The regression coefficient (95% confidence interval) for the number of physicians per 100,000 population was 0.246 (0.113-0.378). CONCLUSION: The number of physicians is associated with the number of nighttime emergency surgeries.

COVID-19 outbreak trends in South Africa: A comparison of Omicron (B.1.1.529), Delta (B.1.617.2), and Beta (B.1.351) variants outbreak periods.

OBJECTIVES: We provided COVID-19 outbreak trends in South Africa during the Omicron (B.1.1.529), Delta (B.1.617.2), and Beta (B.1.351) variants outbreak periods from November 2020 to March 2022. METHODS: We used the time series summary data of the COVID-19 outbreak for South Africa available in the COVID-19 data repository created by the Center for System and Science and Engineering at Johns Hopkins University and the Our World in Data database by the University of Oxford from January 2020 to March 2022. We used the joinpoint regression model with a data-driven Bayesian information criterion method for analyzing the outbreak trends. In addition, we used density ellipses and partition modeling on the outbreak data. RESULTS: During the Omicron outbreak period, COVID-19 cases in South Africa significantly jumped by 4.7 times from December 01 to December 08, 2021. The average daily growth rate of incidence peaked at 23,000 cases/day until December 16, 2021, which was 18.6 % higher than the peak growth during the Delta outbreak period. South Africa experienced peak growth in COVID-19 cases with 18,611 cases/day (January 04 to January 14, 2021) during the Beta outbreak period and with 19,395 cases/day (July 01 to July 11, 2021) during the Delta outbreak period. Density ellipsoid showed a significant correlation between daily cases and daily death count during the Beta and Delta outbreak period which was not prominent in the Omicron outbreak period. Comparatively higher daily death tolls were reported in days with a recovery rate of less than 89.1 % and 91.9 % in the Beta and Delta outbreak period respectively. The backlog counts may be one of the reasons for the significant increase in daily death tolls during the Omicron period. CONCLUSIONS: During the Omicron period, COVID-19 cases peaked growth was 18.6 % higher than the peak growth during the Delta outbreak period. Despite that fact, growth in death trends in the Omicron outbreak period was found low which might be due to the low mortality rate and case fatality proportion. The emergence of the Omicron variant once again reminds us that- "no one is safe until everyone is safe".

Modulatory Effects of NBF1, an Algal Fiber-Rich Bioformula, on Adiponectin and C-Reactive Protein Levels, and Its Therapeutic Prospects for Metabolic Syndrome and Type-2 Diabetes Patients.

An unhealthy diet can lead to the development of metabolic disorders. C-reactive protein (CRP) has been reported to be an inflammatory component of metabolic disorders. Additionally, reduced adiponectin (APN) levels is known as a predictor of metabolic disorders. We report on the beneficial effects of NBF1, an algal fiber-rich formula, on CRP, APN, and diabetes markers. Additionally, associations between dietary nutrients, CRP, and APN were investigated. A dietary survey that used a brief self-administered diet history questionnaire, a validated 58-item fixed-portion-type questionnaire, and a 4-week placebo-controlled dietary intervention were carried out. The latter consisted of a twice daily intake of 3 g of sujiaonori alga-based powder as a supplement (NBF1, n = 16), whereas the placebo group received the same amount of corn starch powder (n = 15). CRP and APN levels were assayed by ELISA. Clinical cases comprising three subjects with metabolic disorders treated with NBF1, including two type 2 diabetes mellitus patients and one subject with hypercholesterolemia, are also reported. They received 2.1g NBF1 once daily for 12 weeks. Intakes of algal fiber and n-3 PUFA were positively associated with the increase of APN, and n-3PUFA intake was inversely associated with CRP. All cases had improved metabolic health profile.

Trends in per Capita Food and Protein Availability at the National Level of the Southeast Asian Countries: An Analysis of the FAO's Food Balance Sheet Data from 1961 to 2018.

We aimed to analyze the temporal trends in the per capita food (kcal/day/person) and protein (g/day/person) availability at the national level in the Southeast Asian (SEA) countries from 1961 to 2018. To avoid intercountry variations and errors, we used a dataset derived from the FAO's old and new food balance sheets. We used the joinpoint model and the jump model to analyze the temporal trends. The annual percentage change (APC) was computed for each segment of the trends. Per capita food and protein availability in the SEA countries increased significantly by 0.8% per year (54.0%) and 1.1% per year (85.1%), respectively, from 1961 to 2018. During the 1960s, 1970s, and 1980s the per capita food availability in mainland SEA did not change significantly and was less than 2200 kcal/person/day. Since the early 1990s, food availability increased appreciably in the mainland SEA countries, except for Cambodia, which has experienced the increasing trend from the late 1990s. Distinct from the mainland, maritime SEA countries showed an up-down-up growth trend in their per-capita food availability from 1961 to 2018. Food-availability growth slowed down for Brunei (since the mid-1980s) and Malaysia (since mid-the 1990s) whereas it increased for Indonesia (1.5% per year), Timor-Leste (0.9% per year), and the Philippines (0.8% per year). Per capita protein availability trends in the mainland SEA countries were similar to the countries' per capita food availability trends. Since the late 1980s, Thailand and since the late 1990s, other mainland SEA countries experienced a significant growth in their per capita protein availability. Since the late 1990s, per capita protein availability in Vietnam increased markedly and reached the highest available amount in the SEA region, following Brunei and Myanmar. Per capita protein availability increased almost continuously among the maritime SEA countries, except for Timor-Leste. Marked inequality did exist between maritime and mainland SEA countries in per capita food-availability growth till the mid-1990s. Considerable increases in per capita food availability have occurred in most of the SEA countries, but growth is inadequate for Timor-Leste and Cambodia.

Income Change One Year after Confirmed Cancer Diagnosis and Its Associated Factors in Japanese Patients.

The number of patients who survive for a long time after cancer diagnosis is rapidly increasing; however, such patients experience major problems such as returning to work and changes in their income. This study aimed to determine the extent of income changes of cancer patients during the first year after cancer diagnosis and identify the influencing factors. From November 2019 through January 2020, we conducted a multicenter, self-administered anonymous survey of cancer patients in Kagawa Prefecture, Japan. The number of questionnaires collected was 483 (recovery rate 60.4%), and the number of participants who met the inclusion criteria was 72. Mean year-on-year income level one year since cancer diagnosis was 66% (SD: 32%; median: 70%). Cancer stage (p = 0.016), employment status at diagnosis (p = 0.006), and continued employment at the same workplace (p = 0.001) were associated with income change. Findings from this study showed that cancer patients lost one-thirds of their income one year after their diagnosis. It was related to the stage of their illness, employment status, and continued employment at their workplace just before the diagnosis. Employers should provide cancer patients with the support they need to keep them employed.
