RESUMEN

BACKGROUND: Elderly are one of the most heterogeneous and vulnerable groups who have a higher risk of nutritional problems. Malnutrition is prevalent among hospitalized elderly but underdiagnosed and almost undistinguishable from the changes in the aging process. The Geriatric Nutritional Risk Index (GNRI) is a tool created to predict nutrition-related complications in hospitalized patients. This study aims to measure the prevalence of nutritional risk using the GNRI among hospitalized elderly Egyptian inpatients and to determine the association between the GNRI and selected adverse clinical outcomes. METHODS: A hospital-based prospective cohort study was conducted among 334 elderly patients admitted to a tertiary specialized geriatric university hospital in Cairo, Egypt from August 2021 to June 2022. Within 48 hours after hospital admission, socio-demographic characteristics, blood biomarkers, anthropometric measurements, and nutritional risk assessment by the GNRI score were obtained. Patients were divided into three groups based on their GNRI: high, low, and no nutritional risk (GNRI<92, 92-98, and >98) respectively. Patients were followed up for the occurrence of adverse outcomes during hospital stay (bed sores, Healthcare-Associated Infections (HAIs), hospital Length of Stay (LOS), and hospital mortality) and three months after discharge (non-improvement medical status, appearance of new medical conditions, hospital readmission and 90-day mortality). Multivariable regression and survival analysis were conducted. RESULTS: The prevalence of high-nutritional risk was 45.5% (95% CI, 40%-51%). Patients with high risk had significantly longer LOS than those with no risk. The high-nutritional risk was significantly associated with the development of bed sores (Adjusted Odds Ratio (AOR) 4.89; 95% CI, 1.37-17.45), HAIs (AOR: 3.18; 95% CI, 1.48-6.83), and hospital mortality (AOR: 4.41; 95% CI, 1.04-18.59). The overall survival rate was significantly lower among patients with high-nutritional risk compared to those with no risk. CONCLUSION: GNRI is a simple and easily applicable objective nutritional screening tool with high prognostic value in this Egyptian sample of patients. The findings of this study signal the initiation of the application of this tool to all geriatric hospitals in Egypt.

RESUMEN

A novel and sensitive fluorescence ratiometric method is developed for urea detection based  on the pH-sensitive response of two fluorescent carbon dot (CD) systems: R-CDs/methyl red (MR) and NIR-CDs/Cu2+. The sensing mechanism involves breaking down urea using the enzyme urease, releasing ammonia and increasing pH. At higher pH, the fluorescence of NIR-CDs is quenched due to the enhanced interaction with Cu2+, while the fluorescence of R-CDs is restored as the acidic MR converts to its basic form, removing the inner filter effect. The ratiometric signal (F608/F750) of the R-CDs/MR and NIR-CDs/Cu2+ intensities changed in response to the pH induced by urea hydrolysis, enabling selective and sensitive urea detection. Detailed spectroscopic and morphological investigations confirmed the fluorescence probe design and elucidated the sensing mechanism. The method exhibited excellent sensitivity (0.00028 mM LOD) and linearity range (0.001 - 8.0 mM) for urea detection, with successful application in milk samples for monitoring adulteration, demonstrating negligible interference and high recovery levels (96.5% to 101.0%). This ratiometric fluorescence approach offers a robust strategy for selective urea sensing in complicated matrices.

RESUMEN

BACKGROUND & AIMS: HCV test and treat campaigns currently exclude pregnant women. Pregnancy offers a unique opportunity for HCV screening and to potentially initiate direct-acting antiviral treatment. We explored HCV screening and treatment strategies in two lower middle-income countries with high HCV prevalence, Egypt and Ukraine. METHODS: Country-specific probabilistic decision models were developed to simulate a cohort of pregnant women. We compared five strategies: S0, targeted risk-based screening and deferred treatment (DT) to after pregnancy/breastfeeding; S1, World Health Organization (WHO) risk-based screening and DT; S2, WHO risk-based screening and targeted treatment (treat women with risk factors for HCV vertical transmission [VT]); S3, universal screening and targeted treatment during pregnancy; S4, universal screening and treatment. Maternal and infant HCV outcomes were projected. RESULTS: S0 resulted in the highest proportion of women undiagnosed: 59% and 20% in Egypt and Ukraine, respectively, with 0% maternal cure by delivery and VT estimated at 6.5% and 7.9%, respectively. WHO risk-based screening and DT (S1) increased the proportion of women diagnosed with no change in maternal cure or VT. Universal screening and treatment during pregnancy (S4) resulted in the highest proportion of women diagnosed and cured by delivery (65% and 70%, respectively), and lower levels of VT (3.4% and 3.6%, respectively). CONCLUSIONS: This is one of the first models to explore HCV screening and treatment strategies in pregnancy, which will be critical in informing future care and policy as more safety/efficacy data emerge. Universal screening and treatment in pregnancy could potentially improve both maternal and infant outcomes. IMPACT AND IMPLICATIONS: In the context of two lower middle-income countries with high HCV burdens (Egypt and Ukraine), we designed a decision analytic model to explore five different HCV testing and treatment strategies for pregnant women, with the assumption that treatment was safe and efficacious for use in pregnancy. Assuming direct-acting antiviral treatment during pregnancy would reduce vertical transmission, our findings indicate that the provision of universal (rather than risk-based targeted) screening and treatment would provide the greatest maternal and infant benefits. While future trials are needed to assess the safety and efficacy of direct-acting antivirals in pregnancy and their impact on vertical transmission, there is increasing recognition that the elimination of HCV cannot leave entire subpopulations of pregnant women and young children behind. Our findings will be critical for policymakers when developing improved screening and treatment recommendations for pregnant women.

RESUMEN

BACKGROUND: Waterpipe tobacco smoking rates in the Eastern Mediterranean region are among the highest worldwide, yet little evidence exists on its economics. Estimates of demand elasticities for tobacco products are largely limited to cigarettes. This study aimed to estimate own-price and cross-price elasticities of demand for cigarettes and waterpipe tobacco products in Lebanon, Jordan and Palestine. METHODS: A volumetric choice experiment was conducted using nationally representative household surveys. The choice experiment elicited respondents' stated purchases of eight cigarette and waterpipe tobacco product varieties by hypothetically varying prices. Data were analysed using zero-inflated Poisson models that yielded demand elasticity estimates of cigarette and waterpipe tobacco consumption. RESULTS: The study included 1680 participants in Lebanon (50% female), 1925 in Jordan (44.6% female) and 1679 in Palestine (50% female). We found the demand for premium cigarettes to be price elastic (range, -1.0 to -1.2) across all three countries, whereas the demand for discount cigarettes was less elastic than premium cigarettes in Lebanon (-0.6) and Jordan (-0.7) and more elastic in Palestine (-1.2). The demand for premium waterpipe tobacco was highly elastic in Lebanon (-1.9), moderately elastic in Jordan (-0.6) and inelastic in Palestine (0.2). The cross-price elasticity between cigarettes and waterpipe tobacco was near zero, suggesting that the two products are not considered to be close substitutes by consumers. CONCLUSIONS: These results serve as a strong evidence base for developing and implementing fiscal policies for tobacco control in the Eastern Mediterranean region that address cigarettes and waterpipe tobacco products.

RESUMEN

INTRODUCTION: Despite the high prevalence of waterpipe tobacco smoking in the Eastern Mediterranean region, evidence supporting its fiscal measures is limited. We modelled the impact of waterpipe tobacco-specific excise taxes on consumption, government revenue and premature deaths averted in Jordan, Lebanon and Palestine. METHODS: We developed a simulation model using country-specific and market share-specific price, consumption and price elasticity data from WHO, UN Comtrade and nationally representative surveys. We modelled increases to specific excise taxes to meet a 35.9% tax burden on 20 g of waterpipe tobacco in Lebanon and Jordan, in line with the global average, and to double government revenues from excise duties in Palestine, which has surpassed this average. RESULTS: Specific excise tax was raised by $1.14 ($0.18-$1.32) in Jordan, $2.41 ($0.03-$2.44) in Lebanon (alongside removal of ad valorem taxes) and $2.39 ($1.72-$4.11) in Palestine per 20 g of waterpipe tobacco. Government revenue increased by $126.3 million in Jordan, $53.8 million in Lebanon and $162.4 million in Palestine while waterpipes smoked decreased by 32.4% in Jordan, 71.0% in Lebanon and 16.3% in Palestine. The corresponding numbers of premature deaths averted annually were approximately 162 000; 1 000 000; and 52 000. DISCUSSION: Increases in waterpipe tobacco-specific excise taxes substantially reduce smoking and increase government revenue and averted premature deaths in Jordan, Lebanon and Palestine. This has positive implications for both public health and financing and should be considered a policy priority.

RESUMEN

Economic evaluation of tobacco control policies is common in high-income settings and mainly focuses on cigarette smoking. Evidence suggests that increasing the excise tax of tobacco products is a consistently effective tool for reducing tobacco use and is an efficient mechanism for increasing government revenues. However, less research has been conducted in low/middle-income countries where other tobacco forms are common. This paper presents insights from our work on the economics of waterpipe tobacco smoking conducted in the Eastern Mediterranean Region where waterpipe smoking originated and is highly prevalent. The specific areas related to economics of waterpipe smoking considered herein are: price elasticity, taxation, government revenue, expenditure and healthcare costs. This paper aims to provide practical guidance for researchers investigating the economics of waterpipe tobacco with potential implications for other novel tobacco products. We present lessons learnt across five thematic areas: data, demand, taxes, equity and health modelling. We also highlight knowledge gaps to be addressed in future research. Research implications include designing comprehensive assessment tools that investigate heterogeneity in waterpipe smoking patterns; accounting for cross-price elasticity of demand with other tobacco products; exploring the change in waterpipe tobacco smoking in response to a tax increase and analysing the equity impact of waterpipe tobacco control interventions.

RESUMEN

BACKGROUND: Coronavirus disease-2019 (COVID-19) could be associated with morbidity and mortality in immunocompromised children. OBJECTIVE: The objective of this study was to measure the frequency of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among hospitalized children with cancer and to detect the associated clinical manifestations and outcomes. METHODOLOGY: A prospective noninterventional study including all hospitalized children with cancer conducted between mid-April and mid-June 2020 in Ain Shams University Hospital, Egypt. Clinical, laboratory, and radiologic data were collected. SARS-CoV-2 infection was diagnosed by reverse transcription polymerase chain reaction tests in nasopharyngeal swabs. RESULTS: Fifteen of 61 hospitalized children with cancer were diagnosed with SARS-CoV-2. Their mean age was 8.3±3.5 years. Initially, 10 (66.7%) were asymptomatic and 5 (33.3%) were symptomatic with fever and/or cough. Baseline laboratory tests other than SARS-CoV-2 reverse transcription polymerase chain reaction were not diagnostic; the mean absolute lymphocyte count was 8.7±2.4×109/L. C-reactive protein was mildly elevated in most of the patients. Imaging was performed in 10 (66.7%) patients with significant radiologic findings detected in 4 (40%) patients. Treatment was mainly supportive with antibiotics as per the febrile neutropenia protocol and local Children Hospital guidance for management of COVID-19 in children. CONCLUSIONS: Pediatric cancer patients with COVID-19 were mainly asymptomatic or with mild symptoms. A high index of suspicion and regular screening with nasopharyngeal swab in asymptomatic hospitalized cancer patients is recommended.

RESUMEN

BACKGROUND: Smoking negatively impacts COVID-19 severity and adverse outcomes. Evidence on whether smoking is associated with SARS-Co-V2 infection and having a positive test is scarce, particularly from low-and middle-income countries, where most of the world's billion smokers live. The inconsistency in relevant findings calls for study designs and analyses to account for possible confounders including background characteristics and pre-existing co-morbidities, to disentangle the specific effect of smoking. In healthcare workers (HCWs) the frequency of exposure to COVID-19 cases adds another layer of risk that was not factored in previous studies. We examined the association of HCWs' tobacco/nicotine use (never, former, and current use) with having a positive SARS-Co-V2 test result and symptoms suggestive of infection, accounting for demographics, exposures, and co-morbidities. METHODS: A prospective cohort study of 4040 healthcare workers with baseline and follow-up screening took place during April-June 2020 in 12 healthcare facilities in Cairo, Egypt. Data on demographics, tobacco/nicotine use (manufactured or roll-your-own cigarettes, waterpipe tobacco, and electronic devices), co-morbidities, symptoms, exposures, and SARS-Co-V2 investigations were analyzed. Multinomial and multivariable logistic regression analyses were performed. RESULTS: Overall, 270/4040 (6.7, 95%CI: 5.9-7.5) had positive SARS-CoV-2 tests, 479 (11.9%) were current and 79 (2.0%) were former tobacco/nicotine users. The proportion of positive tests was 7.0% (243/3482, 95%CI: 6.1-7.8) among never, 5.1% (4/79, 95%CI: 0.1-10.0) among former, and 4.8% (23/479, 95%CI: 2.9-6.7) among current users. HCWs' SARS-CoV-2 test results did not vary significantly by single/multiple or daily/non-daily tobacco/nicotine use. Compared to never users, former users were more likely to self-report a pre-existing medical condition (ORadjusted1.87, 95%CI: 1.05-3.33, p = 0.033), and to experience symptoms suggestive of COVID-19 (ORadjusted1.76, 95%CI: 1.07-2.90, p = 0.027). After adjustment, former (ORadjusted0.45, 95%CI: 0.11-1.89, p = 0.273) and current (ORadjusted0.65, 95%CI: 0.38-1.09, p = 0.101) tobacco/nicotine use was not associated with HCWs' SARS-CoV-2 positive test results. CONCLUSIONS: This is the first report on this association from low- and middle-income countries with high tobacco/nicotine use prevalence. In this HCW cohort, having a positive SARS-CoV-2 test was not associated with tobacco/nicotine use after accounting for demographics, exposures, and co-morbidities. Additional population-based studies could use such preliminary evidence to investigate this controversial association.

RESUMEN

OBJECTIVES: Despite the high burden of hepatitis C virus (HCV) infection in Egypt, screening of pregnant women is not yet universal, making national and global elimination unlikely. This study assessed the proportion of pregnant women who were screened for HCV infection at delivery, the prevalence and risk factors for HCV infection, the associated adverse neonatal outcomes, and the real-life linkage to care of infected women and follow-up of their infants' HCV status and timing of testing. METHODS: Data were collected from medical records of a retrospective cohort of all pregnant women who were admitted to a university hospital in Cairo for delivery between January and June 2018 (n = 6734). HCV antibody- and RNA-positive women and their infants were prospectively followed-up by phone interviews till September 2019. RESULTS: 2177 (32.3%) pregnant women were screened for HCV infection. 19 (0.9%) tested HCV antibody- and RNA-positive. Being ≥ 30 years old (ORa 3.6, 95% CI: 1.4-9.2; P = 0.009), history of abortion (ORa 3.5, 95% CI: 1.2-10.3; P = 0.022) and blood transfusion (ORa 29.1, 95% CI: 9.6-88.4; P < 0.001) were independent risk factors for infection. Adverse neonatal outcomes did not vary significantly among HCV antibody-positive and antibody-negative women. Only 13 (68.4%) HCV antibody- and RNA-positive women started treatment with direct-acting antivirals (DAAs) post-breastfeeding (two completed the treatment course and were cured). Four (21.1%) did not start treatment, and two (10.5%) were lost to follow-up. All infants of the 13 HCV antibody- and RNA-positive women who started DAA therapy tested HCV RNA-negative within their first year of life. CONCLUSION: Extending screening services to all pregnant women and better linkage to care are essential for the national elimination of HCV infection.


OBJECTIFS: Malgré la charge élevée de l'infection par le virus de l'hépatite C (VHC) en Egypte, le dépistage des femmes enceintes n'est pas encore universel, ce qui rend peu probable l'élimination nationale et mondiale. Cette étude a évalué la proportion de femmes enceintes qui ont été dépistées pour l'infection par le VHC à l'accouchement, la prévalence et les facteurs de risque d'infection par le VHC, les résultats néonatals indésirables associés et le ralliement réel avec les soins aux femmes infectées et le suivi du statut VHC de leurs nourrissons et le calendrier des tests. MÉTHODES: Les données ont été collectées à partir des dossiers médicaux d'une cohorte rétrospective de toutes les femmes enceintes admises dans un hôpital universitaire du Caire pour un accouchement entre janvier et juin 2018 (n = 6734). Les femmes testées positives pour les anticorps et l'ARN du VHC et leurs nourrissons ont fait l'objet d'un suivi prospectif par des entretiens téléphoniques jusqu'en septembre 2019. RÉSULTATS: 2.155 (32,3%) femmes enceintes ont été dépistées pour l'infection au VHC. 19 (0,9%) ont été testées positives pour les anticorps et l'ARN du VHC. Avoir ≥30 ans (ORa: 3,6 ; IC95%: 1,4-9,2; p = 0,009), les antécédents d'avortement (ORa : 3,5 ; IC 95%: 1,2-10,3; p = 0,022) et la transfusion sanguine (ORa: 29,1 ; IC95%: 9,6-88,4; p <0,001) étaient des facteurs de risque indépendants d'infection. Les résultats néonatals défavorables ne variaient pas de manière significative entre les femmes positives et négatives aux anticorps anti-VHC. Seules 13 (68,4%) femmes positives pour les anticorps et l'ARN du VHC ont commencé un traitement avec des antiviraux à action directe (AAD) après l'allaitement (deux ont terminé le traitement et ont été guéries). Quatre (21,1%) n'ont pas commencé le traitement et deux (10,5%) ont été perdus de vue. Tous les nourrissons des 13 femmes positives pour l'anticorps et l'ARN du VHC qui ont commencé un traitement par AAD ont été testés négatifs pour l'ARN du VHC au cours de leur première année de vie. CONCLUSION: L'extension des services de dépistage à toutes les femmes enceintes et un meilleur lien avec les soins sont essentiels pour l'élimination nationale de l'infection par le VHC.

RESUMEN

BACKGROUND: Egypt is one of three countries where half of female genital mutilation/cutting (FGM/C) victims live, despite its ban. To inform policy on the awareness of this ban and the impact of other interventions, this study sought to assess FGM/C-related knowledge, perceptions, and determinants of disagreement with FGM/C and circumcision of future daughters among university students. METHODS: A cross-sectional study was conducted using a self-administered questionnaire in a random sample of 502 male and female students in Menoufia University between September and December 2017. Bivariate and multivariable logistic regression analyses were performed. RESULTS: Students were 21.0 ± 1.6 years old; 270 (54.0%) were males, 291 (58.0%) were non-medical students, and 292 (58.2%) were rural residents. 204 (46.7%) students were not aware of the ban and their main source of information about FGM/C was educational curricula or health education sessions (162, 37.0%). Only 95 (19.0%) students had good knowledge about FGM/C. 217 (43.3%) students were neutral towards discontinuing FGM/C. 280 (56.2%) students disagreed with FGM/C. 296 (59.3%) students disagreed with circumcision of their future daughters; independent determinants of this outcome were awareness of the ban (ORa = 1.9) and disagreement with: FGM/C preserves females' virginity (ORa = 5.0), has religious basis (ORa = 3.8), makes females happier in marriage (ORa = 3.5), enhances females' hygiene (ORa = 2.1). CONCLUSIONS: Knowledge about FGM/C and its ban is low, even in this educated population. FGM/C is still misperceived as a religious percept. Maximizing the utilization of health education and curricula might help increase anti-FGM/C attitudes among university students with neutral perceptions and initiate the much-needed momentum for elimination.

RESUMEN

INTRODUCTION: There is a tendency of waterpipe smokers to advance their practice toward concurrent use (poly-tobacco use) of other tobacco products and nicotine delivery systems. This study investigated poly-tobacco use among waterpipe smokers, and its effect on their quit intention. METHODS: Descriptive cross-sectional design was utilized to recruit a convenience sample of university students who used waterpipe in three East Mediterranean countries. Using an internet-based survey, data were collected regarding participants' demographics, use of alternative tobacco products and nicotine delivery systems, and waterpipe quitting profile. Results: A total of 2290 students agreed to participate, among which 1116 (45.3%) reported using at least one tobacco product beside waterpipe. Poly-tobacco use was highest (61.1%) in Egypt, followed by Jordan (45.1%) and Palestine (33.1%). Across countries, cigarettes were the most common product (45.2%, n = 924) followed by cigar (18.6%, n = 374) and e-shisha (17.5%, n = 353). Conversely, the least reported product was smokeless tobacco (7.5%, n = 151) preceded by regular pipe (9.5%, n = 193). Participants who were males (OR = 2.83, 95% CI: 2.18-3.65), older (22-29 years) (OR = 1.15, 95% CI: 1.09-1.22), unemployed (OR = 1.58, 95% CI: 1.22-2.04), and those who initiated waterpipe at a younger age (OR = 0.87, 95% CI: 0.87-0.91) had higher odds of being poly-smokers. Poly-tobacco users were significantly more resistant to quit waterpipe. Conclusion: This study demonstrates poly-tobacco use as a rising phenomenon among waterpipe smokers and highlights the necessity for initiating advanced interventions to help waterpipe poly-tobacco users quit this dangerous type of addiction. Various country-specific programs are needed considering the various products used by the users.

RESUMEN

BACKGROUND: Although Egypt places four generic pictorial health warnings (PHWs) on the front and back half of waterpipe tobacco packs (WTPs), waterpipe tobacco smoking (WTS) rates have continued to rise. It has been suggested that PHWs would be more salient if placed on the waterpipe device itself. This qualitative study explored how participants perceived the effects placing PHWs on waterpipe devices would have on warning salience and uptake or quitting of WTS. METHODS: We conducted 10 focus groups and 10 in-depth interviews with 90 adult waterpipe smokers and non-smokers, men and women, who lived in rural, semi-urban and urban regions of Egypt. We presented participants with four novel PHWs of different sizes positioned randomly at four locations on a waterpipe device (the glass body, metal holder, mouthpiece or hose), one at a time. At each session, participants viewed a PHW on all four locations. Novel warnings were shown on plain labels with a dark uniform background and featured pictures, text and the quitline number. Transcripts were analysed using thematic analysis. RESULTS: Participants thought placing PHWs on waterpipe devices might increase salience, prevent WTS initiation or trigger quit attempts; they favoured placing PHWs on the glass body, mouthpiece or waterpipe hose. Both waterpipe smoker and non-smoker participants thought these potential effects would affect non-smokers or non-established smokers more than established waterpipe users. CONCLUSIONS: Our exploratory study suggests that PHWs featured prominently on waterpipe devices could potentially deter experimentation with waterpipe tobacco products and promote cessation, especially among non-established users.

RESUMEN

A simple and highly sensitive ultra-high-performance liquid chromatographic-diode array (UHPLC-DAD) detection method was developed and validated for the simultaneous estimation of levetiracetam (LEV) and lacosamide (LAC). It was clinically proven that the combination of LEV and LAC exhibits a synergistic effect against refractory seizures in mice, which was the motivation for the analysis of this binary mixture both in bulk and in human urine samples. The binary mixture was resolved on a Hypersil BDS C18 analytical column, utilizing a mobile phase of 0.050 mol L-1 phosphate buffer (pH 5.60), methanol and acetonitrile in the ratio (80:10:10 v/v/v) using catechol as an internal standard. The mobile phase was pumped at a flow rate of 1.2 mL min-1 with diode array detection at 205 nm for both drugs and 270 nm for IS. Calibration curves were linear with correlation coefficient >0.9990 over the studied concentration range of 0.1-70.0 µg mL-1 for both drugs. The developed method was reproducible with low relative standard deviation values for intra- and inter-day precision (<2.0%). Both drugs were determined in bulk, pharmaceutical formulations and human urine samples without any interference from complex matrices.

RESUMEN

The prevalence of waterpipe tobacco smoking in the Eastern Mediterranean Region is at alarmingly high levels, especially among young people. The objective of this research was to evaluate the preferences of young adult waterpipe smokers with respect to potential individual-level determinants of waterpipe smoking using discrete choice experiment methodology. Participants were young adult university students (18-29 years) who were ever waterpipe smokers, recruited from universities across four Eastern Mediterranean countries: Jordan, Oman, Palestine and the United Arab Emirates. The Internet-based discrete choice experiment, with 6 × 3 × 2 block design, evaluated preferences for choices of waterpipe smoking sessions, presented on hypothetical waterpipe café menus. Participants evaluated nine choice sets, each with five fruit-flavored options, a tobacco flavored option (non-flavored), and an opt-out option. Choices also varied based on nicotine content (0.0% vs. 0.05% vs. 0.5%) and price (low vs. high). Participants were randomized to receive menus with either a pictorial + text health-warning message or no message (between-subjects attribute). Multinomial logit regression models evaluated the influence of these attributes on waterpipe smoking choices. Across all four samples (n = 1859), participants preferred fruit-flavored varieties to tobacco flavor, lower nicotine content and lower prices. Exposure to the health warning did not significantly predict likelihood to opt-out. Flavor accounted for 81.4% of waterpipe smoking decisions. Limiting the use of fruit flavors in waterpipe tobacco, in addition to accurate nicotine content labeling and higher pricing may be effective at curbing the demand for waterpipe smoking among young adults.

RESUMEN

Background: The objective of this study was to examine waterpipe tobacco smoking patterns, places of smoking, and prices paid among university students in the Eastern Mediterranean Region. Methods: A cross-sectional online survey was administered to a convenience sample of university students in three countries. Participants were young adults (18-29 years) who were ever waterpipe smokers, from Egypt (n = 728), Jordan (n = 790), and Palestine (n = 722). Measures included past-30-day waterpipe smoking, frequency, intensity, place of smoking, and prices paid per waterpipe smoking session and for packaged waterpipe tobacco. Logistic regression models evaluated the factors associated with past-30-day waterpipe smoking. Results: Past-30-day waterpipe smoking (prevalence) was observed among 60.7%, 67.7% and 63.1% of students from Egypt, Jordan, and Palestine, respectively. Among past-30-day smokers, past-5-day waterpipe smoking (frequency) was observed among 28.9%, 51.5%, and 48.6% of participants, respectively. Smoking in a café was highest among participants from Egypt (74.0%), followed by those from Palestine (44.8%), and Jordan (43.0%). Mean price paid per session was USD 0.99 (Egypt), USD 8.07 (Jordan), USD 6.05 (Palestine). The corresponding mean prices per packet were USD 0.86, USD 4.96, and USD 5.55, respectively. Predictors of past-30-day waterpipe smoking included younger age of initiation, male gender, employment, and smoking waterpipe alone. Conclusions: This study contributes to our understanding of waterpipe smoking patterns, places of smoking, and prices paid among young adults in a region with alarmingly high smoking rates. Understanding waterpipe smoking behaviors can inform the design of policy and educational interventions to curb its rising threat.

RESUMEN

BACKGROUND: Normal serum alanine aminotransferase (ALT) levels differ with age, gender, and body mass index. Adjusting the upper limits of normal (ULN) for ALT needs further research in different populations. Aim of this work was to monitor the effect of successful chronic hepatitis C (CHC) treatment on the ALT levels in patients with normal pretreatment ALT. METHODS: Data of 1160 CHC patients with persistent pretreatment normal liver enzymes were retrospectively analyzed. Treatment response to direct acting antiviral agents (DAAs) therapy was recorded. Changes in ALT levels before and after treatment were analyzed by patients' demographic, laboratory, and radiologic characteristics. Areas under the receiver operating characteristic curve (AUROC) of ALT after treatment were used to generate a new ALT ULN. RESULTS: Males were 568 (49%) and females 592 (51%) with a mean age of 50.7 years. After treatment, mean (±SD) of ALT levels significantly decreased from (26.3±7.8) to (19.1±10.9). This reduction was more significant in interferon-free than interferon-based regimens. ROC curve analyses suggested a new ALT ULN cut off (26.4 IU/L) in the treated patients (sensitivity=78.6%, specificity=83.8%, AUROC=0.89. This cutoff dropped to 14.7 IU/L in cirrhotic patients (sensitivity=77.4%, specificity=44.7%, AUROC=0.612). The identified cutoffs were 16.3 IU/L (sensitivity=66.7%, specificity=47.5%, AUROC=0.499) and 15.5 IU/L (sensitivity=76.5%, specificity=51.3%, AUROC=0.576) in males and females, respectively. CONCLUSION: The current ALT ULN needs readjustment to identify new normal cutoffs in CHC patients. Posttreatment cutoffs differ according to gender, pretreatment liver affection, and treatment regimen.

RESUMEN

BACKGROUND: The use of multiple tobacco products is an emerging trend. Studies on multiple use among waterpipe smokers are limited. OBJECTIVES: We aimed to estimate the proportion of other tobacco products used by current adult waterpipe smokers in Egypt and identify the determinants of multiple tobacco product use. METHODS: Population-based surveys were conducted using interview questionnaires during 2015-2017 in urban Cairo and rural Menoufia. Participants aged 18 years and older were selected using purposive quota non-random sampling. The total sample included 2 014 participants. We analysed the data on 1 490 current waterpipe smokers. Variables recorded included: tobacco use, health beliefs, waterpipe smoking behaviour, sociodemographic characteristics, and perceived effectiveness of pictorial health warnings on waterpipe tobacco packs. Current waterpipe smokers were classified as waterpipe-only users and multiple tobacco product users. RESULTS: Almost half (47.9%) of the current waterpipe smokers used multiple tobacco products; 93.4% were dual users and 6.6% poly-users. The other tobacco products used were cigarettes (86.4%), electronic nicotine delivery systems (ENDS) (7.0%) or both (6.6%). Multiple users were more likely to be younger than waterpipe-only users. Young adult female waterpipe smokers used ENDS 12 times more than young adult males (48.8% versus 4.1% respectively). Non-daily waterpipe smoking, usually smoking at cafes, higher education and knowledge of pictorial health warnings were independent predictors of multiple tobacco product use. CONCLUSION: Multiple tobacco product use was common among current waterpipe smokers in our study. Interventions to tackle non-cigarette and multiple tobacco use, especially in young adults, are urgently needed.

RESUMEN

BACKGROUND & AIMS: >80% of people chronically infected with hepatitis C virus (HCV) live in resource-limited countries, yet the excess mortality associated with HCV infection in these settings is poorly documented. METHODS: Individuals were recruited from three villages in rural Egypt in 1997-2003 and their vital status was determined in 2008-2009. Mortality rates across the cohorts were compared according to HCV status: chronic HCV infection (anti-HCV antibody positive and HCV RNA positive), cleared HCV infection (anti-HCV antibody positive and HCV RNA negative) and never infected (anti-HCV antibody negative). Data related to cause of death was collected from a death registry in one village. RESULTS: Among 18,111 survey participants enrolled in 1997-2003, 9.1% had chronic HCV infection, 5.5% had cleared HCV infection, and 85.4% had never been infected. After a mean time to follow-up of 8.6years, vital status was obtained for 16,282 (89.9%) participants. When compared to those who had never been infected with HCV in the same age groups, mortality rate ratios (MRR) of males with chronic HCV infection aged <35, 35-44, and 45-54years were 2.35 (95% CI 1.00-5.49), 2.87 (1.46-5.63), and 2.22 (1.29-3.81), respectively. No difference in mortality rate was seen in older males or in females. The all-cause mortality rate attributable to chronic HCV infection was 5.7% (95% CI: 1.0-10.1%), while liver-related mortality was 45.5% (11.3-66.4%). CONCLUSIONS: Use of a highly potent new antiviral agent to treat all villagers with positive HCV RNA may reduce all-cause mortality rate by up to 5% and hepatic mortality by up to 40% in rural Egypt.
