The negative impact of the COVID-19 pandemic on breast cancer care in Brazil: a time series study in regions with different human development indices

BackgroundThe impact of the COVID-19 pandemic on breast cancer care across Brazilian regions with varying Human Development Index (HDI) levels remains unclear. This study evaluates the pandemic’s effects on screening mammograms, tumor staging at diagnosis, and treatment initiation in the Brazilian Public Health System between 2017 and 2022, focusing on regions with different HDI levels.MethodsThis ecological time series study uses an inflection point regression model and monthly percentage change (MPC) to analyze an open-access Brazilian Public Healthcare System dataset. The study focuses on trends and variations in these variables among women aged 50–69 in three state groups classified by HDI: Group A (very high), Group B (medium), and Group C (high).ResultsThe average monthly rate of screening mammograms was highest in Group A (10.70) and lowest in Group B (8.38). At the onset of the COVID-19 pandemic, screening rates dropped significantly, with the most significant decline in Group B (58.6% decrease) and the smallest in Group A (45.7% decrease), lasting for three months. Subsequently, this variable recovered until December 2022 but was insufficient to restore the total series MPC to pre-pandemic levels. Group B had the lowest average rate of early-stage (0-II) diagnoses (2.88), while Group C had the highest (3.68). Early-stage diagnoses declined in the first three months of the pandemic, followed by a partial recovery that was insufficient to restore the pre-pandemic MPC levels. The proportion of advanced-stage diagnoses was highest in Group B (49.02%) and lowest in Group A (45.97%). The pandemic maintained the upward trend of advanced-stage (III-IV) diagnoses across all groups in the total time series. The average proportion of treatments initiated after 60 days of diagnosis was above 60% across all groups, with Group B at 64.50%. This variable began to rise 3 to 4 months after the pandemic and continued increasing until December 2022, with a greater intensity than the pre-pandemic period across all groups.ConclusionThe COVID-19 pandemic reduced breast cancer screening and early diagnosis in Brazil, leading to more advanced cases and treatment delays across all regions, with varying impacts according to regional HDI levels.

Zoom Boom or Bust? Understanding Post-Pandemic Interest in Facial Plastic Surgery via Google Trends.

To understand post-pandemic interest in plastic surgery procedures via Joinpoint analysis of Google Trends search data. Google Trends was used to quantify search volumes from January 2019-December 2022 for select cosmetic face and body procedures in the United States. A keyword analytic tool (Keywords Everywhere) extracted absolute search volumes (average monthly searches). Joinpoint analysis assessed search trends over time reported as monthly percentage change (MPC). All procedures queried, including a non-cosmetic control (cataract surgery), demonstrated expected declines at the start of the COVID-19 pandemic. Blepharoplasty, face lift, neck lift, and Botox demonstrated statistically significant increase in search volumes that remained elevated relative to pre-pandemic levels. Rhinoplasty, fillers, and abdominoplasty interest increased initially followed by return to pre-pandemic levels by the end of 2022. The remainder of search terms did not show a clear temporal associated with COVID-19 lockdowns. The "Zoom Boom" appears to be a real phenomenon reflected by sustained increase in public interest in relation to facial plastic procedures. NA Laryngoscope, 2024.

EVALUATION OF THE EFFECT OF EXPANSIONARY MONETARY POLICIY IMPLEMENTED DURING COVID-19 ON THE TÜRKİYE, EU AND US ECONOMIES

In this article, the effect of expansionary monetary policy implemented during the covid-19 on the Türkiye, the EU and the USA economies has been evaluated. The beginning of the pandemic covers the period between January 2020 and January 2024. The effects of the monthly percentage change in M3 money supply on unemployment, real economic growth and inflation are presented comparatively with graphs. As a result, while Türkiye was the country where the increase in M3 money supply increased inflation the most, the country where unemployment increased most rapidly at the initial phase of the pandemic was the USA. However, over time, the Fed managed to reduce unemployment to historical low levels with the measures it took. The consequence of the contractionary monetary policy after the pandemic, inflation has been brought under control and the option of reducing interest rates has recently come to the fore. Rising inflation in the EU was also taken under control, but unemployment still remained high

Insights from Chilean NCDs Hospitalization Data during COVID-19.

The COVID-19 pandemic has affected the lifestyles of people of all ages, conditions and occupations. Social distance, remote working, changes in diet and a lack of physical activity have directly and indirectly affected many aspects of mental and physical health, particularly in patients with many comorbidities and non-communicable diseases (NCDs). In our paper, we analyzed COVID-19 hospitalized and non-hospitalized cases according to comorbidities to assess the average monthly percentage change (AMPC) and monthly percentage change (MPC) using open access data from the Chilean Ministry of Science, Technology, Knowledge and Innovation. As expected, the infection mainly affected patients with comorbidities, including cardiovascular risk factors. The hospitalized cases with obesity and chronic lung disease increased throughout the period of June 2020-August 2021 (AMPC = ↑20.8 and ↑19.4%, respectively, p < 0.05), as did all the non-hospitalized cases with comorbidities throughout the period (AMPC = ↑15.6 to ↑30.3 [p < 0.05]). The increases in hospitalizations and non-hospitalizations with comorbidities may be associated with physical inactivity. A healthy lifestyle with regular physical activity may have had a protective effect on the COVID-19 severity and related events in the post-pandemic period, especially for the NCD population.

A retrospective study of traffic offenses associated with driving under the influence of drugs in China

Objective This study aimed to investigate the prevalence and pattern of traffic offenses associated with driving under the influence of drugs (DUID) in 31 provinces of mainland China. Methods Traffic offenses were extracted from the nationally representative court file disclosure website. Drivers convicted of traffic offenses associated with DUID were included. The monthly percentage change (MPC) in rates was estimated by fitting negative binomial regression models to assess the time trends. Moran’s I was used to determine the correlations of DUID-related rates among surrounding provinces. Results In total, 896 individuals convicted of DUID offenses were identified (April 2007 to March 2022). Of these, 769 individuals were involved in traffic crashes, and they killed 629 people. Regarding the types of drugs, 638 used amphetamine-type stimulants (ATS; methamphetamine, 3,4-methylenedioxymethamphetamine, amphetamine, and tenamfetamine), 104 used ketamine, 104 used opioids (heroin, morphine, methadone, codeine, and tramadol), 20 used caffeine, 4 used tetrahydrocannabinol, and 1 used gamma-hydroxybutyric acid. The offense trends among overall drug users (MPC, −1.1; p < .001) declined from 2014 to 2020. The trends also decreased for DUID-related traffic crashes (−1.5; p < .001) and deaths (−1.7; p < .001) during the same period. Except in three provinces, ATS-related offense rates were higher than opioid-related offense rates. Ketamine-related offense rates showed a significant positive correlation among the surrounding provinces (Moran’s I, 0.22; p < .01), and South China had the highest ketamine-related offense rates. Conclusions In the sample, the case fatality rate was 70.7%, which was a strong indicator of underreporting, and most minor DUID-related offenses could not be captured by Chinese court files. The frequency of drug screening tests for people should be increased. The traffic police in Qinghai, Tibet, and Xinjiang should always be equipped with fast screening test kits for drugs, which could increase the possibility of identifying DUID offenders.

Trends in the Cost of Medicines, Consultation Fees and Clinic Visits in Malaysia's Private Primary Healthcare System: Employer Health Insurance Coverage.

To examine trends in the cost of medicines, consultation fees and clinic visits among the employees covered by the employer health insurance in Malaysia's private primary healthcare system in Malaysia. Retrospective cross-sectional study. PMCare claims database from January 2016 to August 2019. A total of 83,556 outpatient clinic visits involving 10,150 IIUM employees of the International Islamic University Malaysia (IIUM) to private general practitioners (GPs). During the study period, IIUM adopts the incentive structure of capping coverage at Ringgit Malaysia (RM) 45/outpatient visit (USD 10.58) to cover for consultation fees and medicine costs. The monthly percentage change in the number of clinic visits, medicine costs, consultation fees and total costs between January 2016 and August 2019. A simple linear regression using Stata v15.1 was also performed to measure the association between the characteristics of the prescribed medicines and medicine charges. The number of clinic visits per patient increased by 17% from January 2016 to August 2019, with consultation fees increasing by 113.9% and total costs by 7.9% per clinic visit per patient. Conversely, the cost of medicines and the number of medicines prescribed per clinic visit per patient decreased by 39.7% and 6.3%, respectively. Within the incentive structure of capping the total amount of coverage per clinic visit, medicine costs were reduced by decreasing the number of medicines prescribed, to offset the increased consultation fees. This may create perverse incentives that affect medicine use with negative consequences for the health system and health insurers.

Impact of European Union Label Changes for Fluoroquinolone-Containing Medicinal Products for Systemic and Inhalation Use: Post-Referral Prescribing Trends.

Concerns of the persistence and severity of the adverse effects of fluoroquinolones, mainly involving the nervous system, muscles and joints, resulted in the 2018 referral procedure led by the European Medicines Agency (EMA). They advised to stop prescribing fluoroquinolones for infections of mild severity or of a presumed self-limiting course and for prevention of infections, plus to restrict prescriptions in cases of milder infections where other treatment options are available, and restrict in at-risk populations. We aimed to examine whether the impact of EMA regulatory interventions implemented throughout 2018-2019 had an impact on fluoroquinolone prescribing rates. A retrospective population-based cohort study was conducted using electronic health care records from six European countries between 2016 and 2021. We analysed monthly incident fluoroquinolone use rates overall and for each fluoroquinolone active substance through flexible modelling via segmented regression to detect time points of trend changes, in monthly percentage change (MPC). The incidence of fluoroquinolone use ranged from 0.7 to 8.0/1000 persons per month over all calendar years. While changes in fluoroquinolone prescriptions were observed over time across countries, these were inconsistent and did not seem to be temporally related to EMA interventions (e.g., Belgium: February/May 2018, MPC - 33.3%, 95% confidence interval [CI] - 35.9 to - 30.7; Germany: February/May 2019, MPC - 12.6%, 95% CI - 13.7 to - 11.6]; UK: January/April 2016, MPC - 4.9%, 95% CI - 6.2 to - 3.6). The regulatory action associated with the 2018 referral did not seem to have relevant effects on fluoroquinolone prescribing in primary care.

Trends in Nicotine Strength in Electronic Cigarettes Sold in the United States by Flavor, Product Type, and Manufacturer, 2017-2022.

Most e-cigarettes contain highly addictive nicotine. This study assessed trends in nicotine strength in e-cigarettes sold in the United States during January 2017-March 2022. We obtained January 2017-March 2022 national retail e-cigarette sales data from NielsenIQ. We assessed monthly average nicotine strength overall, by e-cigarette product and flavor type, and manufacturer. A Joinpoint regression model assessed the magnitude and significance of changes in nicotine strength. During January 2017-March 2022, monthly average nicotine strength of e-cigarette products increased from 2.5% to 4.4%, an average of 0.8% per month (p < .001). Monthly average nicotine strength of disposable e-cigarettes increased the most (average monthly percentage change [AMPC] = 1.26%, p < .001) as compared to prefilled pods (AMPC = 0.6%, p < .001) and e-liquids (AMPC = 0.5%, p = .218). Monthly average nicotine strength for all flavors of e-cigarette products increased except for mint-flavored products. Increases were greatest for beverage-flavored products (AMPC = 2.1%, p < .001), followed by menthol-flavored products (AMPC = 1.2%, p < .001). Among the top 10 e-cigarette manufacturers assessed, monthly average nicotine strength decreased for Juul Labs products from 5% to 4.7% (AMPC = -0.1%, p < .001) but increased significantly for five manufacturers' products and remained unchanged at 5%-6% for four manufacturers' products. Monthly average nicotine strength of e-cigarette products increased overall, for most product and flavor types, and for some manufacturers in the United States during the study period. Imposing maximum limits on nicotine strength of e-cigarettes together with other evidence-based tobacco control strategies can help reduce the use of e-cigarettes among youth and increase tobacco product cessation among adults. From January 2017 to March 2022, the monthly average nicotine strength of disposable e-cigarettes increased substantially and exceeded prefilled pods since May 2020. E-cigarettes with menthol flavor and youth-appealing flavors, like fruit, also had sharp increases in monthly average nicotine strength. Among the top 10 e-cigarette manufacturers, monthly average nicotine strength increased or remained unchanged at a high nicotine level for all manufacturers' products, except Juul Lab's products. Comprehensive strategies including restricting sales of all flavored e-cigarettes, restricting youth tobacco product access, and imposing maximum limits on nicotine strength may help reduce youth e-cigarette use and increase tobacco cessation.

Suspected Nonfatal Cocaine-Involved Overdoses Overall and With Co-involvement of Opioids.

The Centers for Disease Control and Prevention (CDC) developed a syndrome definition for detection of suspected nonfatal cocaine-involved overdoses. The definition can be used to monitor trends and detect anomalies in emergency department (ED) syndromic surveillance data at the national, state, and local levels. This study describes the development of the nonfatal, unintentional/undetermined intent cocaine-involved overdose (UUCOD) definition and analysis of trends over time. CDC developed the UUCOD definition to query ED data in CDC's National Syndromic Surveillance Program (NSSP). Data between 2018 and 2021 were analyzed from 29 states sharing data access in the Drug Overdose Surveillance and Epidemiology (DOSE) System via NSSP. Using Joinpoint regression, trends were analyzed for UUCOD overall, by sex and age group, and for UUCOD co-involving opioids. Time trends between 2018 and 2021 were analyzed by examining average monthly percentage change. Individual trend segments and trend inflection points were analyzed by examining monthly percentage change. During 2018-2021, a total of 27 240 UUCOD visits were identified by the syndrome definition. Analyses identified different patterns in trends for males and females, with largely similar trends for persons aged 15 to 44 years and 45 years or older. Analyses also identified seasonal patterns with increases in spring/summer months in UUCOD overall and UUCOD co-involving opioids and declines for both in fall/winter months. This UUCOD syndrome definition will be useful for ongoing monitoring of suspected nonfatal overdoses involving cocaine and co-involving cocaine and opioids. Ongoing assessment of cocaine-involved overdose trends might identify anomalies requiring further investigation and inform deployment of resources.

Trends in Hysterectomy Rates Associated With the Coronavirus Disease 2019 (COVID-19) Pandemic.

To compare nationwide trends in the rate of inpatient and outpatient hysterectomy between 2019 and 2020 during the coronavirus disease 2019 (COVID-19) pandemic. Using weighted data from the National Inpatient Sample and the National Ambulatory Surgery Sample, we examined the number of hysterectomies performed by month from 2019 through 2020. Monthly trends were compared between years overall, stratified by the route of surgery (abdominal, laparoscopic, and vaginal) and by indication for surgery (benign, preinvasive, cancer). Trends analyses were conducted using Joinpoint regression and reported as average monthly percentage change (AMPC). Differences in demographic characteristics between the years were compared using χ 2 tests. From January 2019 through December 2020, after weighting, 1,029,792 hysterectomies were performed, including 548,802 (53.2%) in 2019 and 480,990 (46.7%) in 2020. Starting in January 2020, monthly cases declined significantly, from 40,240 to a nadir of 10,566 hysterectomies in April 2020 (AMPC -29.2%, 95% CI -39.8% to -16.8%) ( P <.001). The subsequent months saw a significant increase in cases, from the nadir in April 2020 to 40,023 cases in July 2020 (AMPC 39.4%, 95% CI 18.6-63.9%) ( P =.001), which then stabilized to the end of the year (AMPC -1.3%, 95% CI -4.8% to 2.4%) ( P =.46). In March 2020 there was a 24.0% decrease, in April 2020 a 74.2% decrease, and in May 2020 a 35.1% decrease compared with the respective months in 2019. The rates of vaginal hysterectomy declined more than the rates of other routes of surgery, and procedures performed for benign and preinvasive disease decreased more than those for cancer. The rate of hysterectomy in the United States decreased in 2020 compared with 2019, with the greatest decrease from March to May of 2020, corresponding with the initial wave of COVID-19.

Reduction of adverse outcomes from cesarean section by surgical-site infection prevention care bundles in maternity.

To reduce average surgical-site infection (SSI) rates to less than 7.5%, as well as other complications by incrementally implementing an SSI prevention care bundle in maternity: (1) ChloraPrep; (2) PICO dressings, performing elective cesarean sections in a main theater rather than a labor ward and warming blankets; (3) vaginal cleansing; and (4) Hibiscrub. In this prospective cohort study, the association between categorical variables was assessed by χ2 tests, temporal trends in the monthly percentage change of SSI were measured using the Joinpoint Regression Program v4.7.0.0. In all, 1682 women (mean age 33.1± 5.2 years) underwent either elective (53.9%) or emergency (46.1%) cesarean section. After a small initial increase (10.0%-11.8%), SSI progressively declined to 4.4% (χ2 = 22.1, P< 0.001), as did sepsis, reoperation or readmission for SSI: from 12.5% to 0.5% (χ2 = 90.1, P< 0.001). The rates of SSI fell progressively with the cumulative introduction care bundle components. The average monthly percentage change was -14.0% (95% confidence interval -21.8% to -5.4%, P= 0.004), and the average SSI rate was kept below 7.5% for the last 12 months of the study. The maternal SSI prevention care bundle is simple and inexpensive; it effectively reduces SSI after a cesarean section and should be offered routinely to women undergoing cesarean section.

A158 COMPARING CORTIMENT® AND PREDNISONE IN ULCERTATIVE COLITIS: A POPULATION-BASED STUDY OF OUTCOMES

BackgroundIn August 2016 Cortiment® was approved for use in ulcerative colitis (UC) patients in Canada, but not approved for reimbursement; the Canadian Agency for Drugs and Technology in Health cited no comparable benefit for its use over other approved UC medications. Real-world data comparing Cortiment® to other UC medications is limited, especially during the COVID-19 pandemic where the use of steroids is counter-indicated for COVID-19-related outcomes.AimsTo examine the comparative risk of hospitalization, surgery, and infection after initiation of Cortiment® or oral corticosteroids among UC patients using real-world dataMethodsUsing population-based data from Alberta Canada, two cohorts were compared: 1. Patients dispensed Cortiment® and an ICD diagnostic code for UC [9: 556.X; 10: K51.X] (August 1, 2016 to October 31, 2019); and, 2. Validated (algorithm) UC patients dispensed a >30 day supply or >500mg in 24 hours of prednisone/prednisolone (April 1, 2016 to October 31, 2019). All hospitalizations, IBD-surgery, or infections (i.e., pneumonia, c.diff, sepsis, tuberculosis) that occurred 6 or 12 months from initial medication dispensing were identified. Cox-proportional hazard models, with Hazard Ratios (HR), assessed comparative outcomes. Kaplan-Meier survival curves were created, and Poisson regression (or negative binomial) used to assess the Average Monthly Percentage Change (AMPC) with associated 95% confidence intervals (CI).ResultsWe identified 917 Cortiment® and 2,404 Prednisone patients. Over the study period, prednisone dispensing significantly decreased (AMPC:-2.53% [CI:-2.85,-2.21]) while Cortiment® remained stable. Dispensing of Cortiment® significantly decreased the hazard of hospitalization (all types, except surgery) at 12 months as compared to prednisone, and significantly decreased the hazard of an infection at both 6 and 12 months (Table 1, Fig 1).ConclusionsThe use of Cortiment® in a real-world setting is associated with fewer deleterious outcomes, and its use during a pandemic should be preferred, especially when it’s counterpart can exacerbate negative COVID-19-related outcomes.Table 1Cortiment (%)Prednisone (%)N9172,404AgeMedian (Q1; Q3)45.9 (33.3, 58.5)43.9 (31.8, 59.1)SexMale430 (46.9)1,356 (56.4)Female487 (53.1)1,048 (43.6)Cortiment; n(%)Prednisone; n (%)HR (95%CI)All Hosp6-months107 (11.67)409 (17.0)0.83 (0.63, 1.11)1-year152 (16.58)592 (24.6)0.64 (0.54, 0.77)IBD-Related6-months72 (7.85)279 (11.6)0.67 (0.52, 0.87)1-year102 (11.12)394 (16.4)0.66 (0.53, 0.82)IBD-Specific6-months58 (6.32)223 (9.28)0.91 (0.63, 1.32)1-year79 (8.62)312 (12.98)0.66 (0.51, 0.84)IBD-Surgery6-months13 (1.42)57 (2.37)0.61 (0.33, 1.11)1-year24 (2.62)101 (4.20)1.05 (0.61, 1.82)Infection6-months25 (2.73)152 (6.32)0.43 (0.28, 0.65)1-year41 (4.47)213 (8.86)0.49 (0.35, 0.69) Kaplan-Meier Survival Curves of 1-year Outcomes: A) All Hospitalizations; B) IBD-Related Hospitalizations; C) IBD-Specific Hospitalizations; and, D) Any Infection.Dashed LineCortiment CohortSolid LinePrednisone/Prednisolone CohortFunding AgenciesFerring Pharmaceuticals

Trends in Cigar Sales and Prices, by Product and Flavor Type-the United States, 2016-2020.

Cigar smoking has increased in recent decades as the cigar product landscape has diversified. This study assessed trends in US cigar sales during 2016-2020. Unit sales and average unit price for cigars were assessed during January 3, 2016-June 13, 2020, overall and by product and flavor type, for the 48 contiguous US states and D.C. Assessed cigar types were large cigars, little cigars, and cigarillos; assessed flavor types were tobacco/unflavored, candy/sweets, fruit, menthol, alcohol, coffee, other flavors, and no flavor stated. A joinpoint regression model was used to assess the magnitude and significance of sales trends. During January 3, 2016-June 13, 2020, unit sales of cigarillos increased (average monthly percentage change [AMPC] = 0.7%, p < .001), while unit sales of large cigars (AMPC = -0.8%, p < .001) and little cigars decreased (AMPC = -0.2%, p < .001). The average price of cigarillos gradually decreased since mid-August 2017 (AMPC = -0.1%, p < .001), and the average price of little cigars decreased from mid-June 2016 to mid-June 2019 (AMPC = -0.3%, p < .001). In contrast, the average price of large cigars increased during the entire study period (AMPC = 0.6%, p < .001). Irrespective of cigar type, tobacco-flavored/unflavored products were the most commonly sold cigars during the assessed period; however, sales of other flavors varied by cigar type. Cigar sales and price vary by type over time in the United States, including sales of cigarillos (94.2% of unit sales) increasing as their prices have decreased in recent years. Public health strategies are warranted to address the full scope of cigar types being used in the United States. Surveillance of cigar sales data, including product characteristics, can provide a timely complement to self-reported survey data of cigar use. This study assessed trends in US cigar sales during 2016-2020, including by product and flavor type. The findings indicate that sales of cigarillos, which comprise most cigar sales in the United States during the assessed period, increased as their prices decreased. Sales of certain flavors, such as candy/sweet cigarillos and coffee large cigars, increased significantly. These findings reinforce the importance of evidence-based strategies, including increasing price and restricting flavors, to reduce the affordability and consumption of cigars in the United States.

Long-term impact of the 2008 economic crisis in Spain on road traffic collisions mortality by socioeconomic position.

We aimed to assess the effect of the 2008 crisis on road traffic collision (RTC) mortality in Spain, by socioeconomic position (SEP) and type of road use. This prospective, country-wide study covered all adults living in Spain and aged ≥30 years in November 2001. The long-term effect of the crisis was assessed by measuring the monthly percentage change (MPC) in RTC mortality between the pre-crisis (2002-2007) and crisis period (2008-2011). During the recession, RTC mortality fell more in people with low compared to high SEP, so MPCs difference between periods were of a higher magnitude in the low compared to high SEP groups, especially among men motorcyclists. RTC mortality trends were favorable following the 2008 crisis, particularly among low-SEP groups. In men motorcyclists, the upward trend of the pre-crisis period reversed course.

Determining the nutritional immunity information-seeking behaviour during the COVID-19 pandemic in India: a Google Trends data analysis.

During COVID-19, the Internet was a prime source for getting relevant updates on guidelines and desirable information. The objective of the present study was to determine the nutritional immunity information-seeking behaviour during COVID-19 in India. Google Trends (GTs) data on relevant COVID-19 and nutritional topics were systematically selected and retrieved. Data on newly reported COVID-19 cases were also examined on a daily basis. The cross-correlation method was used to determine the correlation coefficient between the selected terms and daily new COVID-19 cases, and the joinpoint regression models were utilised to measure monthly percent change (MPC) in relative search volumes (RSV). Online. People using Google search during the period 1 January 2020-31 August 2020 in India. The date of peak searches can be attributed to the COVID-19 guidelines announcement dates. All the nutritional terms showed a significant increase in average monthly percentage change. The higher than the average daily rise in COVID-19 cases leads to a higher than average increase in RSV of nutritional terms with the greatest association after 14-27 d. The highest mean relative search volume for nutritional terms was from Southern India (49·34 ± 7·43), and the lowest was from Western India (31·10 ± 6·30). There was a significant rise in the Google searches of nutritional immunity topics during COVID-19 in India. The local/regional terms can be considered for better outreach of public health guidelines or recommendations. Further automation of Google Trends using programming languages can help in real-time monitoring and planning various health/nutritional events.

Differences and similarities between emergency department syndromic surveillance and hospital discharge data for nonfatal drug overdose

Emergency department syndromic surveillance and hospital discharge data have been used to detect and monitor nonfatal drug overdose, yet few studies have assessed the differences and similarities between these two data sources. The Centers for Disease Control and Prevention Drug Overdose Surveillance and Epidemiology system data from 14 states were used to compare these two sources at estimating monthly overdose burden and trends from January 2018 through December 2019 for nonfatal all drug, opioid-, heroin-, and stimulant-involved overdoses. Compared to discharge data, syndromic data captured 13.3% more overall emergency department visits, 67.8% more all drug overdose visits, 15.6% more opioid-involved overdose visits, and 78.8% more stimulant-involved overdose visits. Discharge data captured 18.9% more heroin-involved overdoses. Significant trends were identified for all drug (Average Monthly Percentage Change [AMPC]=1.1, 95% CI=0.4,1.8) and stimulant-involved overdoses (AMPC=2.4, 95% CI=1.2,3.7) in syndromic data; opioid-involved overdoses increased in both discharge and syndromic data (AMPCDischarge=0.9, 95% CI=0.2,1.7; AMPCSyndromic=1.9, CI=1.1,2.8). Results demonstrate that discharge data may be better for reporting counts, yet syndromic data are preferable to detect changes quickly and to alert practitioners and public health officials to local overdose clusters. These data sources do serve complementary purposes when examining overdose trends.

Effectiveness and trend forecasting of tuberculosis diagnosis after the introduction of GeneXpert in a city in south-eastern Brazil.

To evaluate the effectiveness of a rapid molecular test for the detection of tuberculosis (TB) and to predict the rates of disease in a municipality of Brazil where TB is endemic. An ecological study was carried out in Ribeirão Preto-SP on a population of TB cases notified between 2006 and 2017. Monthly TB incidence rates and the average monthly percentage change (AMPC) were calculated. In order to identify changes in the series, the breakpoint technique was performed; the rates were modelled and predictions of the incidence of TB until 2025 were made. AMPC showed a fall of 0.69% per month in TB and human immunodeficiency virus (TB-HIV) co-infection, a fall of 0.01% per month in general and lung TB and a fall of 0.33% per month in extrapulmonary TB. With the breakpoint technique, general and pulmonary TB changed in structure in late 2007, and extrapulmonary TB and TB-HIV co-infection changed in structure after 2014, which is considered the cut-off point. The IMA(3) models were adjusted for general and pulmonary TB and TB-HIV co-infection, and the AR(5) models for extrapulmonary TB, and predictions were performed. The rapid molecular test for TB is the method currently recommended by the WHO for the diagnosis of the disease and its main advantage is to provide faster, more accurate results and to already check for drug resistance. It is necessary that professionals encourage the use of this technology in order to optimize the diagnosis so that the treatment begins as quickly as possible and in an effective way. Only by uniting professionals from all areas with health policies aimed at early case identification and rapid treatment initiation it is possible to break the chain of TB transmission so that its rates decrease and the goals proposed by the WHO are achieved.

Exploring Public Awareness of Overwork Prevention With Big Data From Google Trends: Retrospective Analysis.

BackgroundTo improve working conditions and prevent illness and deaths related to overwork, the Taiwanese government in 2015, 2016, and 2018 amended regulations regarding working time, overtime, shifts, and rest days. Such policy changes may lead to a rising public awareness of overwork-related issues, which may in turn reinforce policy development.ObjectiveThis study aimed to investigate to what extent public awareness of overwork-related issues correlated with policy changes.MethodsPolicies, laws, and regulations promulgated or amended in Taiwan between January 2004 and November 2019 were identified. We defined 3 working conditions (overwork, long working hours, and high job stress) related to overwork prevention, generated a keyword for each condition, and extracted the search volumes for each keyword on the Google search engine as proxy indicators of public awareness. We then calculated the monthly percentage change in the search volumes using the Joinpoint Regression Program.ResultsApparent peaks in search volumes were observed immediately after policy changes. Especially, policy changes in 2010 were followed by a remarkable peak in search volumes for both overwork and working hours, with the search volumes for overwork increased by 29% per month from June 2010 to March 2011. This increase was preceded by the implementation of new overwork recognition guidelines and media reports of several suspected overwork-related events. The search volumes for working hours also steadily increased, by 2% per month in September 2013 and afterward, reaching a peak in January 2017. The peak was likely due to the amendment to the Labor Standards Act, which called for “1 fixed and 1 flexible day off per week,” in 2016. The search volumes for job stress significantly increased (P=.026) but only by 0.4% per month since March 2013.ConclusionsOver the past 15 years, Taiwanese authorities have revised and implemented several policies to prevent overwork-related health problems. Our study suggests a relationship between the implementation of policies that clearly defined the criteria for overwork and working hours and the rising public awareness of the importance of overwork prevention and shorter working hours.

A multimodal intervention program to control a long-term Acinetobacter baumannii endemic in a tertiary care hospital

BackgroundAcinetobacter baumannii causes frequently nosocomial infections worldwide. Its ability to survive on dry surfaces facilitates its spread and the persistence of endemic situations, especially in the intensive care units (ICUs).The objective of this paper is to describe a multicomponent intervention program designed to control a hyperendemic persistence of multidrug-resistant A. baumannii (MDR-Ab) and to characterize its impact.MethodsDesign: Quasi-experimental intervention study based on open cohorts.Setting: Public tertiary referral centre. Period: January 2009–August 2017.Intervention: multifaceted program based on environmental decontamination, hand hygiene, antimicrobial stewardship, contact precautions, active surveillance, weekly reports and regular meetings.Analysis: joinpoint regression and interrupted time-series analysis.ResultsThe intervention was successfully implemented. Through the study period, the compliance with contact precautions changed from 0 to 100% and with hand hygiene, from 41.8 to 82.3%. Between 2012 and 2016, the antibiotic consumption decreased from 165.35 in to 150.44 daily-defined doses/1000 patients-days in the ICU. The incidence density of MDR-Ab in the ICU was 10.9 cases/1000 patients-days at the beginning of the intervention. After this moment, the evolution of the incidence density of MDR-Ab was: between months 0 and 6°, it remained stable; between months 7° and 10°: there was an intense decrease, with an average monthly percentage change (AMPC) = − 30.05%; from 11° month until the end, the decrease was lighter but continuous (AMPC:-2.77%), achieving an incidence density of 0 cases/1000 patients-days on the 18° month, without any new case for 12 months. From the 30° month until the end of the study period, several little outbreaks of MDR-Ab were detected, all of them rapidly controlled. The strains of MDR-Ab isolated during these outbreaks were not clonally related with the previously endemic one, which supports its eradication from the environmental reservoirs.ConclusionThe multicomponent intervention performed by a multidisciplinary team was effective to eradicate the endemic MDR-Ab.
