The Impact

The Kingdom of Saudi Arabia is one of the largest Arab countries with a moderate annual problem of tuberculosis that is either pulmonary or extra-pulmonary. TB is still one of the most significant health troubles in the KSA, affecting different nationalities (Saudis, non-Saudis), ages, provinces, and genders. The control of TB still faces some challenges in different provinces of the KSA. Data were collected, arranged, analyzed and presented in tables and figures. In this retrospective study, we appraised TB surveillance data for the period between 2013 (1434H) and 2018 (1439H). Data were handled using Microsoft Excel and SPSS version 23. Data were checked for normality using Shapiro-Wilk normality test at 0.05 levels to determine whether they are parametric or nonparametric. Chi-squared, Kruskal Wallis, and analysis of variance tests were used to evaluate trends at a significance level of p< 0.05. Statistical analyses were performed using IBM-SPSS version 23 for Mac OS. We appraised TB surveillance data for the period between 2013 (1434H) and 2018 (1439H). The data included the region of the country (province), age, sex, and nationality (Saudis, non-Saudis). The study evaluated the impact of TB on various nationalities (Saudis and non-Saudis), age groups (0-14, 15-34, 35-55, more than 55 years old), and genders (males and females). Non-Saudis had a higher incidence rate than Saudis in 2013-2018. The number of cases and incidence rates of TB recorded in males between 2013 to 2018 were about two to three times greater than estimates for females. The Makkah, Riyadh, and Jeddah regions attract enormous numbers of non-Saudi migrant workers, who account for ~60% of all TB cases in the KSA. Assessing the main TB risk factors contributing to high TB rates in non-Saudi workers is essential. Furthermore, periodical accurate studies, including evidence-based studies for optimum surveillance, avoidance, spread risk, inspection, control procedures and treatment of TB, should be conducted. These assessments would lead to evaluating the strengths and weaknesses of KSA-NTP’s TB action plan.

Abstract Background The Emergency Repartment (ER) is one of the most used areas in healthcare institutions. Problems with over utilisation and overcrowding have been reported worldwide. This study aims at examining the characteristics of paediatric ER visits, the rate of hospital admissions and its associated predictors at King Fahd Hospital of the University in the Eastern Province of Saudi Arabia. Methods This is a retrospective, medical record-based study. Variables included gender, age group, nationality, complaints, Triage level, shifts and seasons. Descriptive statistics were reported as frequencies/percentages. P-values were obtained through a Chi-Squared test while unadjusted and adjusted odds ratios were estimated by binary logistic regression, where admission was considered as the outcome. Results The total number of paediatric patients included was 46,374, and only 2.5% were admitted. Males comprised 55.4% while females comprised 44.6%. The most common age group were toddlers, and 92.4% of the total sample were Saudis. The most common complaint was fever (26.9%) followed by respiratory symptoms (24.9%). Only 7 patients (0.02%) were classified as triage I (Resuscitation), and most were triage IV (Less urgent) (71.0%). Most visits occurred during the winter months. Adjusted ORs showed that neonates had higher odds of admission (OR = 3.85, 95%CI = 2.57–5.76). Moreover, those presenting with haematological conditions showed an OR of 65.49 (95%CI = 47.85–89.64), followed by endocrine conditions showing an OR of 34.89 (95%CI = 23.65–51.47). Triage I had a very high odds of admission (OR = 19.02, 95%CI = 2.70–133.76), whereas triage V was associated with a very low odds of admission (OR = 0.30, 95%CI = 0.23–0.38). Conclusions A low rate of hospital admission was found in comparison with other rates worldwide. This was mostly attributed to an alarmingly high number of non-urgent ER visits. This further emphasises the problem with improper use of ER services, as these cases should be more appropriately directed towards primary healthcare centres. Further studies to examine the impact of prioritising patients in the ER based on the identified predictors of hospital admission, in addition to the standard triage system, are suggested.

Background:Infections have been associated with a higher risk of systemic lupus erythematosus (SLE) flares, but the impact of influenza infection on SLE flares has not been evaluated.Objectives:We evaluated the association between influenza infection and SLE flares resulting in hospitalization.Methods:SLE flares resulting in hospitalization and influenza cases were ascertained from the Korean national healthcare insurance database (2014-2018). We used a self-controlled case series design. We defined the risk interval as the first 7 days after the influenza index date and the control interval was defined as all other times during the observation period of each year. We estimated the incidence rates of SLE flares resulting in hospitalization during the risk interval and control interval and compared them using a Poisson regression model.Results:We identified 1,624 influenza infections among the 1,455 patients with SLE. Among those, there were 98 flares in 79 patients with SLE. The incidence ratio (IR) for flares during the risk interval as compared with the control interval was 25.75 (95% confidence interval 17.63 – 37.59). This significantly increased the IRs for flares during the risk interval in both women (IR 27.65) and men (IR 15.30), all age groups (IR 17.00 – 37.84), with and without immunosuppressive agent (IR 24.29 and 28.45, respectively), and with and without prior respiratory diseases (IR 21.86 and 26.82, respectively).Conclusion:We found significant association between influenza infection and SLE flares resulting in hospitalization. Influenza infection has to be considered as a risk factor for flares in all SLE patients regardless of age, sex, medications, and comorbidities.References:[1]Kwong, J. C. et al.

Abstract Background In response to the recent serogroup W invasive meningococcal disease (IMD-W) epidemic in the Netherlands, meningococcal serogroup C (MenC) conjugate vaccination for 14-month-olds was replaced with a MenACWY conjugate vaccination, and a mass campaign targeting 14-18 year-olds was executed. We investigated the impact of MenACWY vaccination implementation in 2018-2020 on incidence rates and estimated vaccine effectiveness (VE). Methods We extracted all IMD cases diagnosed between July 2014 and December 2020 from the national surveillance system. We calculated age group-specific incidence rate ratios by comparing incidence rates before (July 2017-March 2018) and after (July 2019-March 2020) MenACWY vaccination implementation. We estimated VE in vaccine-eligible cases using the screening method. Results Overall, IMD-W incidence rate lowered by 61% (95%CI 40-74). It declined by 82% (95%CI 18-96) in vaccine-eligible age group (15-36 month-olds and 14-18 year-olds) and by 57% (95%CI 34-72) in vaccine non-eligible age groups. VE was 92% (95%CI -20-99.5) against IMD-W vaccine-eligible toddlers. No IMD-W cases were reported in vaccine-eligible teenagers after the campaign. Conclusions The MenACWY vaccination programme was effective in preventing IMD-W in the target population. The IMD-W incidence reduction in vaccine non-eligible age groups may be caused by indirect effects of the vaccination programme. However, disentangling natural fluctuation from vaccine-effect was not possible. Our findings encourage the use of toddler- and teenager MenACWY vaccination in national immunization programmes especially when implemented together with a teenager mass campaign during an epidemic.

<p>This quasi-experimental, longitudinal, quantitative study investigated the impact of Extensive Reading (ER) on developing second language (L2) reading comprehension and writing skills among primary school EFL learners in two Arab countries, Egypt and Saudi Arabia. The study is based on an experiment conducted over a nine-month period on a convenience sample of 112 primary school students <em>(n=112</em>) divided into five groups, three experimental groups and two control group, where the students belonged to two different private schools in Egypt and two different international schools in two cities in Saudi Arabia. The experiment, in the form of an enrichment ER program, used graded readers for young learners and was designed to foster ER for pleasure. The study, guided by three hypotheses, incorporated two types of statistical analysis tests, paired samples t-tests and one-way analysis of variance (ANOVA). The statistical analysis tests performed indicated marked improvement in English proficiency in the two experimental groups, with particular reference to reading comprehension and writing. A number of pedagogical implications and recommendations for future research are given. Additionally, the study highlights the issue related to insufficient exposure to English for young Arab EFL learners in their daily lives, which, unfortunately, seems to cause relapses in their L2 intake, despite having an age advantage.</p>

Abstract Background Owing to a persistent increase of serogroup B Neisseria meningitidis (Nm) invasive infections in the Saguenay-Lac-Saint-Jean (SLSJ) region of the province of Quebec (Canada) since 2006, a wide-scale vaccination campaign of individuals aged 6 months to 20 years was conducted between May and December 2014 using the 4-component protein-based meningococcus serogroup B vaccine (4CMenB). Components of this vaccine have shown to potentially cross-react with Neisseria gonorrhoeae (Ng). The study objective was to assess the impact of the vaccination campaign on Ng incidence rate (IR). Methods Ng cases notified to public health authorities during prevaccination period (January 2006 to June 2014) and postvaccination period (July 2014 to June 2017) were analyzed. The impact of this mass campaign was estimated by a Poisson regression model, including the year (11 July–June categories), age (14–20 vs. 21 years and older), and the intervention (0 by default and 1 in those 14–20 years in the period of July 2014 to June 2017). Results Overall vaccine coverage was 82% in the target group. A total of 231 Ng cases were reported among persons 14 years and older (IR: 8.4/100,000 person-years) of the SLSJ region from January 2006 to June 2017. A decrease in the Ng number of cases and IR among individuals 14–20 years was observed during the post-vaccination period whereas it increased in those 21 years and older (figure). Estimate of vaccination impact was an Ng risk reduction of 59% (95% CI: −22% to 84%; P = 0.1). During the same period, Chlamydia trachomatis (Ct) infections increased among persons of both age groups in the SLSJ region. Conclusion Although the estimate of the impact of the campaign was not statistically significant, possibly due to limited size of the study population and the low incidence of the disease, it is congruent with results of a case–control study in New Zealand showing an OMV-MeNZB vaccine effectiveness of 31%. A higher effectiveness of 4CMenB is a plausible hypothesis as three additional proteins also found in Ng are included in the vaccine used in the SLSJ region. The results of this ecologic study suggest cross-protection of 4CMenB vaccine against Ng infections. Further studies on this topic are warranted.

ABSTRACT: Based on the data of “employment and food demand of urban migrant workers”, this paper empirically analyzed the impact of urban pension insurance on the nutritional intake structure of migrant workers. The results showed that participating in urban pension insurance can change the nutritional intake structure of migrant workers. Additionally, fat and protein replace carbohydrate as the main nutrition sources for migrant workers. After controlling the income and labor intensity of migrant workers and other factors, urban pension insurance has a positive effect on the intake of fat and protein of migrant workers for they increase by 13.5% and 8.8% respectively. There is no significant effect on the intake of carbohydrates of migrant workers. The calorie intake of migrant workers increases by 6.8% accounting for the change of nutritional intake structure. Endogenous and robustness tests showed that the above conclusions are robust. Heterogeneity analysis showed that there is no significant difference in the effect of urban pension insurance on calorie intake of migrant workers in different income levels and age groups.

The objective of the study: to study tuberculosis incidence in migrant workers in Russia from 2010 to 2019.Subjects and Methods: data from Federal Statistical Surveillance Forms No. 8 and 33 for 2010-2019, Federal Migration Service data on the number of migrant workers, and Rosstat data on the population of Russia. Pearson's chi-squared test was used for data analysis.Results. Over the past 10 years in Russia, the steadily decreasing tuberculosis incidence in the permanent population has had no direct impact on the spread of tuberculosis among migrant workers. The high incidence of tuberculosis among migrant workers which is many times higher than the one in the permanent population and reaches its maximum in the youngest age groups (18-24 and 25-34 years old), poses a serious threat to the infection control in the permanent population of Russia.

Abstract Background Increased incidence of invasive pneumococcal disease (IPD) attributable to non-vaccine serotypes (NVT) has been reported in several countries following introduction of PCV7 and PCV13 vaccines, concurrently with a reduction in vaccine-type IPD. Such serotype replacement has, importantly, emerged in England, offsetting the benefit of PCV introduction. We scrutinise most recent findings to assess if the estimated increase in NVT disease might result from surveillance artefacts. Methods Using IPD surveillance for 2000-2018, we estimate the impact of PCV7 and PCV13 introduction on age-serotype-specific incidence rates through a synthetic control regression model, building counterfactuals by combining age-specific incidences reported for pathogens unaffected by PCVs. Results Following the introduction of PCV7 and PCV13 (pre-2006 vs post-2011), total IPD incidence declined by 57% and by 76% in children younger than 5. PCV7-IPD decreased by 93% in all age groups, whereas PCV13-IPD declined by 68% since PCV13 was introduced. Importantly, NVT-IPD increased by 43% after PCV7, with non-significant statistical increases in most age groups. Conclusions Through appropriate statistical modelling, we disentangled the impact of vaccine and improved surveillance on the changes in IPD incidence rates. By controlling for the confounding effects of improved surveillance, we are able to estimate a lower serotype replacement. Key messages Pneumococcal vaccine has been beneficial despite serotype replacement. Adequate statistical methods are needed to disentangle the two phenomena.

Abstract Background Increasing evidence suggests that 1-dose human papillomavirus (HPV) vaccination may protect significantly against HPV-related disease. We provide nationwide, real-world data on the risk of genital warts (GWs) after &lt;3 vaccine doses. Methods All Danish women born in 1985–2003 were identified, and individual-level vaccination data were retrieved. The cohort was followed up for first occurrence of GWs until 31 December 2016. Using Poisson regression, we calculated incidence rates (IRs) of GWs per 100 000 person-years and IR ratios (IRRs) with corresponding 95% confidence intervals (CIs) for GWs, according to vaccination status, age at first dose, and calendar time. Results The cohort comprised 1 076 945 girls and women, of whom 485 408 were vaccinated. For girls initiating vaccination at age 12–14 years and 15–16 years, 1-dose vaccine effectiveness (VE) was 71% (IRR = 0.29; 95% CI, .22–.38) and 62% (0.38; .29–.49), respectively, compared with unvaccinated girls. In the same age groups, 2-dose VE was 78% (IRR, 0.22; 95% CI, .18–.26) and 68% (0.32; .26–.38), respectively. After 2009, the IRRs for 3 versus 1 dose and 2 versus 1 dose increased towards unity over calendar time, being 0.69 (95% CI, .57–.84) and 0.86 (.68–1.08) in 2016, respectively. Conclusions In this study, 1 or 2 doses of quadrivalent HPV vaccine was associated with substantial protection against GWs in girls vaccinated at age ≤16 years. The 1-dose VE approached that of 3 or 2 doses over calendar time, probably reflecting the impact of herd protection.
