BACKGROUND: Ethiopia enacted a comprehensive tobacco control law in 2019, which bans tobacco advertising and promotion activities. However, compliance with these laws at points-of-sale (PoS) has not been studied, resulting in a lack of research evidence on how the regulations are implemented. The purpose of the study was to assess compliance with tobacco advertising and promotion laws at PoS in 10 cities in Ethiopia.
METHODS: Multi-stage cluster sampling was used to select 1468 PoS (supermarkets, minimarkets, merchandise stores, regular shops, permanent kiosks, khat shops, street vendors, and food and drink wholesalers). Data were collected using standardized observational checklists. Tobacco advertising and promotion indicators were used to compute indoor and outdoor compliance. Poisson regression models with log link function and robust variance were used to assess factors associated with open display of cigarette packages and indoor non-compliance.
RESULTS: The average indoor compliance rate was 92.9% (95% CI:92.3-93.5). Supermarkets had the highest compliance (99.7%), while permanent kiosks showed the lowest compliance (89.8%). The highest average indoor compliance was observed at PoS in Addis Ababa (98.0%). About 60% of PoS were fully compliant in indoors. Indoor open display of cigarette packages was prevalent (32.5%, 95% CI:30.0-35.1). The average outdoor compliance was 99.6% (95% CI:99.5-99.7). Outdoor full compliance was 96.5%. Open display of cigarettes was significantly higher in permanent kiosks (adjusted prevalence ratio (adjPR) 6.73; 95% CI: 3.96-11.42), regular shops (adjPR 5.16; 95% CI: 3.05-8.75), and khat shops (adjPR 2.06; 95% CI: 1.11-3.83), while indoor non-compliance was significantly higher in these same types of PoS.
CONCLUSIONS: While outdoor compliance rates were relatively high, the lower indoor compliance rates particularly due to the high prevalence of open cigarette package displays indicates a major area for improvement in enforcing anti-tobacco advertising and promotion laws.

BACKGROUND: Pseudomonas aeruginosa is a leading cause of nosocomial Gram-negative bacteraemia. Water systems are a well-documented source of P. aeruginosa and established biofilms are difficult to remove.
OBJECTIVE: To evaluate the efficacy of regular flushing, peracetic acid disinfection, in-tap thermal disinfection, and in-line thermal disinfection to eradicate P. aeruginosa biofilm in a colonized tap model.
METHODS: A simulated tap system was constructed and inoculated with a reference and an environmental strain of P. aeruginosa to form biofilm. Water samples were collected from the taps and P. aeruginosa levels enumerated following disinfection methods. To simulate regular flushing, taps were flushed for 5 min, five times per day with water tested daily. Peracetic acid (4000 ppm) was manually injected into the system and flushed through the system with a pump. Thermal flushing at 60 °C was performed in-line and with an in-tap bypass valve. Tests were conducted with cross-linked polyethylene (PEX) piping and repeated with copper piping.
RESULTS: Regular flushing and peracetic acid applied with a pump did not reduce P. aeruginosa levels. A limited reduction was observed when manually injecting peracetic acid. In-tap thermal flushing eradicated P. aeruginosa in copper piping but not PEX. In-line thermal flushing was the most effective at reducing P. aeruginosa levels; however, it did not eradicate the biofilm.
CONCLUSIONS: In-line thermal flushing was the most effective method to remove P. aeruginosa biofilm. Results vary significantly with the strain of bacteria and the composition of the plumbing. Several methods used in combination may be necessary to remove established biofilm.

To detect the contaminate of faucets in hospitals and the splash during hand washing, and to explore the reasonable layout of hand washing pools. Two faucets with roughly the same spatial layout in the ICU of a third-class first-class general hospital were selected, and the farthest splashing distance and specific splashing points were measured by color paper. Samples were detected by ATP detection technology and routine microbial detection method, and the contaminate of faucets was analyzed. After 72 h of daily hand-washing activities, the furthest distance to the splash point was about 100 cm around the faucet, and the place 40-110 cm around the faucet was contaminated seriously. The farthest distance that the splash point reached was about 80 cm around the faucet with the center of the circle, and the area 40-60 cm around the faucet was heavily contaminated. The distance from the water outlet of the long handle and the short handle faucet to the detection point had a high negative correlation (r = - 0.811, P < 0.001) and a moderate negative correlation (r =  - 0.475, P = 0.001) with the number of splash points, respectively. The qualified rates of ATP detection and microbial culture were 25% and 15%, respectively. Pseudomonas aeruginosa, Staphylococcus epidermidis, and other pathogenic bacteria were detected in the water outlet of the faucet and the surrounding environment. Safe hand hygiene facilities are one of the important guarantees of hand hygiene effect. Clean objects and objects related to patients should not be placed within 1 m range near the water outlet of faucet. Anti-splash baffle should be installed as much as possible when conditions permit to reduce the contaminate caused by splash during hand washing.

Cryopreservation of red blood cells (RBCs) plays an indispensable role in modern clinical transfusion therapy. Researchers are dedicated to finding cryoprotectants (CPAs) with high efficiency and low toxicity to prevent RBCs from cryopreservation injury. This study presents, for the first time, the feasibility and underlying mechanisms of a novel CPA called tris(hydroxymethyl)aminomethane-3-propanesulfonic acid (TAPS) in RBCs cryopreservation. The results demonstrated that the addition of TAPS achieved a post-thaw recovery of RBCs at 79.12 ± 0.67%, accompanied by excellent biocompatibility (above 97%). Subsequently, the mechanism for preventing RBCs from cryopreservation injury was elucidated. On one hand, TAPS exhibits a significant amount of bound water and effectively inhibits ice recrystallization, thereby reducing mechanical damage. On the other hand, TAPS demonstrates high capacity to scavenge reactive oxygen species and strong endogenous antioxidant enzyme activity, providing effective protection against oxidative damage. Above all, TAPS can be readily removed through direct washing, and the RBCs after washing showed no significant differences in various physiological parameters (SEM, RBC hemolysis, ESR, ATPase activity, and Hb content) compared to fresh RBCs. Finally, the presented mathematical modeling analysis indicates the good benefits of TAPS. In summary, TAPS holds potential for both research and practical in the field of cryobiology, offering innovative insights for the improvement of RBCs cryopreservation in transfusion medicine.

OBJECTIVE: To describe fetal brain Magnetic Resonance Imaging (MRI) findings in a large series of monochorionic (MC) pregnancies complicated by Twin Anemia-Polycythemia Sequence (TAPS) prenatally diagnosed, so to characterize the potential intracranial complications associated with this condition, their frequency and potential treatment options.
METHODS: This is a retrospective study of MC twin pregnancies complicated by TAPS and undergone fetal MRI in a single institution from 2006 to 2023. MRI control was performed and post-natal ultrasound (US) or MRI were available.
RESULTS: 1250 MC pregnancies were evaluated in our institution. 50 pregnancies (4%) were diagnosed with TAPS, 29 underwent a fetal brain MRI. 13/29 pregnancies (44.8%) demonstrated brain findings at MRI in at least a twin. Neuroradiological findings were detected in 14/57 twins (24.6%). We detected four main categories of findings: hemorrhagic lesions, T2-weighted white-matter hyperintensities (WMH), brain edema-swelling and venous congestion. Nineteen findings were present in the anemic and three in the polycythemic twins, with a statistically significant ratio between the two groups (p-value = 0.01). Intrauterine MRI follow-up demonstrated the sequalae of hemorrhagic lesions. A complete regression of brain swelling, veins prominence and T2-WMHs was demonstrated after treatment. Postnatal imaging confirmed prenatal features.
CONCLUSIONS: Our work demonstrates that TAPS-related MRI anomalies consisted in edematous/hemorrhagic lesions that occur mostly in anemic rather than in polycythemic twins. Fetoscopic laser surgery could have a potential decongestant role. Therefore, prenatal MRI may help in counselling and management in TAPS pregnancies, especially for the planning of therapy and the monitoring of its efficacy.

BACKGROUND: Banning Point-of-Sale (POS) advertising and product display is an important tobacco control strategy. Depok, Indonesia enacted some regional tobacco control policies regulating the POS environment in 2021. This study examined changes in compliance before and after the implementation of these policies as of 2021.
METHODS: Data collectors visited 180 modern retailers (hyper/supermarkets/convenience stores) and 147 traditional retailers (warungs) in 2019. The same retailers were re-visited in 2021. Data collectors assessed compliance with tobacco product display, and advertising regulations at POS, including if products were displayed in spaces to target minors (near candy or at a child\'s eye-level). Data were analyzed using McNemar and Mann-Whitney U tests.
RESULTS: From 2019 to 2021, in modern retailers, tobacco product display (95.6% vs 52.2%) and product advertising (36.1% vs 3.9%) were significantly reduced (p<0.001). In traditional retailers, tobacco product display (94.6% in 2019, 91.2% in 2021, p>0.05) and product advertising (87.1% in 2019, 87.8% in 2021, p>0.05) remained common during both data collection periods. Tobacco products were commonly displayed in spaces to target minors in both modern retailers (43.3% in 2019, 34.4% in 2021, p>0.05) and traditional retailers (90.5% in 2019, 83.0% in 2021, p>0.05).
CONCLUSIONS: Compliance with bans on tobacco product advertising and display at modern retailers improved significantly from 2019 to 2021; however, most modern retailers continue to display tobacco products in 2021. Traditional retailers remain largely non-compliant. Tobacco products are commonly displayed in areas that target minors. The enforcement of regional regulations should be strengthened, particularly among traditional retailers.
CONCLUSIONS: In Depok, Indonesia, tobacco advertising and product display bans have been implemented; however, more work is needed to support compliance. Enforcement efforts, such as those carried out by civil police, can focus on tobacco product display bans in traditional and modern retailers, and traditional retailers need additional support to remove tobacco product advertising. Retailers may receive money from the tobacco industry for these advertisements. Creative solutions may include supporting retailers in finding alternative advertising revenue.

UNASSIGNED: The aim of our study was to compare maternal, chorionicity and neonatal complications in monochorionic (MC) twins between spontaneously conceived (SC) and assisted reproductive technologies (ART) pregnancies.
UNASSIGNED: This was a retrospective cohort study between January 2010 to December 2019 at a tertiary referral University center. All consecutive pregnancies with MC twins that delivered at our University hospital were included. Maternal, chorionicity and neonatal complications were recorded and compared between SC and ART pregnancies.
UNASSIGNED: 393 MC pregnancies were included for final analysis, including 353 (89.8%) SC and 40 (10.2%) pregnancies conceived after ART. Hypothyroidism was the only maternal condition seen significantly more often in ART pregnancies (35.0% vs 12.5%, p = 0.001). There were no significant differences in chorionicity complications, such as twin-twin transfusion syndrome, selective fetal growth restriction and twin anemia-polycythemia sequence (40.0% in ART pregnancies vs 31.6% in SC pregnancies, p = 0.291). At least one congenital anomaly in one twin was seen significantly more often in ART pregnancies (18.8% vs 8.1%, p = 0.004), especially congenital heart defects (16.3% vs 6.2%, p = 0.005). There were no other significant differences in neonatal outcomes between both groups, however, there were non-significant trends in gestational age at delivery (34 weeks in ART pregnancies vs 35 weeks, p = 0.078) and birthweight (1951 g ± 747 in ART pregnancies vs 2143 g ± 579, p = 0.066).
UNASSIGNED: This is the largest cohort study to date comparing maternal, chorionicity and neonatal complications between MC twin pregnancies after ART and after SC. Hypothyroidism was the only maternal condition occurring more frequently in pregnancies conceived after ART. There were no significant differences in chorionicity complications, in contrast to previously reported studies. While MC twins and ART pregnancies per se are known to be at risk for congenital heart defects, there seems to be a cumulative effect in MC pregnancies conceived after ART.
UNASSIGNED: Das Ziel dieser Studie war es, die mütterlichen, neonatalen und chorionizitätsbedingte Komplikationen von monochorialen (MC) Zwillingen bei spontan gezeugten (SG) bzw. mit Techniken der assistierten Reproduktion (ART) gezeugten Kindern zu vergleichen.
UNASSIGNED: Diese retrospektive Kohortenstudie untersucht den Zeitraum von Januar 2010 bis Dezember 2019 in einem Universitätsklinikum der Maximalversorgung. Alle konsekutiven in unserem Universitätskrankenhaus entbundenen Schwangerschaften mit MC Zwillingen wurden in die Studie aufgenommen. Die mütterlichen, neonatalen und chorionizitätsbedingten Komplikationen wurden aufgezeichnet und ihr Auftreten in SG- und ART-Schwangerschaften wurde verglichen.
UNASSIGNED: Insgesamt wurden 393 MC Schwangerschaften in die Endanalyse aufgenommen, davon waren 353 (89,8%) SG- und 40 (10,2%) ART-Schwangerschaften. Die Schilddrüsenunterfunktion war die einzige mütterliche Komplikation, die signifikant häufiger bei ART-Schwangerschaften auftrat (35,0% vs. 12,5%, p = 0,001). Es gab keine signifikanten Unterschiede in den chorionizitätsbedingten Komplikationen wie fetofetales Transfusionssyndrom, selektive fetale Wachstumsrestriktion und Zwillings-Anämie-Polyzythämie-Sequenz (40,0% in ART-Schwangerschaften vs. 31,6% in SG-Schwangerschaften, p = 0,291). Bei ART-Schwangerschaften trat mindestens eine angeborene Anomalie bei einem Zwilling signifikant häufiger auf (18,8% vs. 8,1%, p = 0,004), insbesondere angeborene Herzfehler (16,3% vs. 6,2%, p = 0,005). Es gab keine anderen signifikanten Unterschiede in den neonatalen Outcomes zwischen beiden Gruppen; es gab aber nichtsignifikante Trends hinsichtlich des Schwangerschaftsalters bei der Entbindung (34 Wochen für ART-Schwangerschaften vs. 35 Wochen, p = 0,078) und des Geburtsgewichts (1951 g ± 747 für ART-Schwangerschaften vs. 2143 g ± 579, p = 0,066).
UNASSIGNED: Es handelt sich hier um die bislang größte Kohortenstudie, die mütterliche, neonatale und chorionizitätsbedingte Komplikationen in MC Zwillingsschwangerschaften untersucht und das Auftreten von Komplikationen in ART-Schwangerschaften mit denen in SG-Schwangerschaften vergleicht. Die Schilddrüsenunterfunktion war die einzige mütterliche Komplikation, die häufiger bei ART-Schwangerschaften auftat. Im Gegensatz zu früheren Studien gab es keine signifikanten Unterschiede in den chorionizitätsbedingten Komplikationen. Während MC Zwillinge und ART-Schwangerschaften bekanntlich ein höheres Risiko für angeborene Herzfehler haben, scheint es einen kumulativen Effekt bei mit ART gezeugten MC Schwangerschaften zu geben.

BACKGROUND: Tobacco advertisement, promotion, and sponsorship (TAPS) in all forms influences youth smoking behaviors. TAPS exposure enhances their smoking frequency and vulnerability. A 2018 Indonesia Ministry of Health (MoH) Survey showed increased smoking prevalence among youth aged 10-18 years. Thus, our objective was to analyze the relationship between TAPS and the increased Indonesian youth smoking behavior.
METHODS: We conducted a secondary analysis of the Indonesian 2019 Global Youth Tobacco Survey. The sample size differed in each variable: current smokers n=3386, ever smoker n=3666, and cigarette consumption per day n=1355. We adjusted for socioeconomic and demographic variables and used logistic regression with youth smoking prevalence as the outcome and TAPS variables as the primary exposures.
RESULTS: The current male youth smoker prevalence was 38.3%, ever smoker was 67%, and high consumption per day smoker (≥2 cigarettes per day) was 39.1%. Youth respondents exposed to the promotion or sponsorship of cigarette products showed an increase in three smoking behaviors. In particular, when youth respondents were exposed to more than one type of cigarette promotion (AOR=1.67, 95% CI: 1.33-2.09) or noticed one type of cigarette sponsorship (AOR=2.06, 95% CI: 1.44-2.93), their odds of all three smoking behaviors (current smoker, ever smoker, and high consumption smoker) increased.
CONCLUSIONS: TAPS increase smoking behaviors among Indonesian youth. Therefore, to protect Indonesian youth health in the future, strategic action is needed to reduce youth smoking by banning all forms of TAPS in Indonesia.

The prevalence of teen smokers has increased during the Covid-19 pandemic. Smoking behavior occurs due to exposure to advertising and the promotion of cigarettes. This quantitative research was conducted using cross-sectional approach. The purpose of the study was to analyze the relationship between advertising exposure and cigarette promotion on adolescent smoking behavior in Malang Regency during the pandemic using the chi-square test. Random sampling on students from several high schools or equal degree in the Kepanjen District was done with a total of 145 respondents. The results showed that there was no significant relationship between age, types of cigarette advertising media at the point of sale, outdoor media, social media, internet, and newspapers or magazines by adolescent smoking behavior during the Covid-19 pandemic (p-value > 0.05). Exposure to cigarette advertisements on television, total exposure to cigarette advertisements, cigarette promotion, and gender had a significant relationship with adolescent smoking behavior during the pandemic (p value < 0.05). Adolescents are quite highly exposed to the various types of advertisements and promotions of cigarettes that can influence increased smoking behavior during the pandemic.

OBJECTIVE: Monochorionic (MC) triplet pregnancies are extremely rare and information on these pregnancies and their complications is limited. We aimed to investigate the risk of early and late pregnancy complications, perinatal outcome and the timing and methods of fetal intervention in these pregnancies.
METHODS: This was a multicenter retrospective cohort study of MC triamniotic (TA) triplet pregnancies managed in 21 participating centers around the world from 2007 onwards. Data on maternal age, mode of conception, diagnosis of major fetal structural anomalies or aneuploidy, gestational age (GA) at diagnosis of anomalies, twin-to-twin transfusion syndrome (TTTS), twin anemia-polycythemia sequence (TAPS), twin reversed arterial perfusion (TRAP) sequence and or selective fetal growth restriction (sFGR) were retrieved from patient records. Data on antenatal interventions were collected, including data on selective fetal reduction (three to two or three to one), laser surgery and any other active fetal intervention (including amniodrainage). Data on perinatal outcome were collected, including numbers of live birth, intrauterine demise, neonatal death, perinatal death and termination of fetus or pregnancy (TOP). Neonatal data such as GA at birth, birth weight, admission to neonatal intensive care unit and neonatal morbidity were also collected. Perinatal outcomes were assessed according to whether the pregnancy was managed expectantly or underwent fetal intervention.
RESULTS: Of an initial cohort of 174 MCTA triplet pregnancies, 11 underwent early TOP, three had an early miscarriage, six were lost to follow-up and one was ongoing at the time of writing. Thus, the study cohort included 153 pregnancies, of which the majority (92.8%) were managed expectantly. The incidence of pregnancy affected by one or more fetal structural abnormality was 13.7% (21/153) and that of TRAP sequence was 5.2% (8/153). The most common antenatal complication related to chorionicity was TTTS, which affected just over one quarter (27.6%; 42/152, after removing a pregnancy with TOP < 24 weeks for fetal anomalies) of the pregnancies, followed by sFGR (16.4%; 25/152), while TAPS (spontaneous or post TTTS with or without laser treatment) occurred in only 4.6% (7/152) of pregnancies. No monochorionicity-related antenatal complication was recorded in 49.3% (75/152) of pregnancies. Survival was apparently associated largely with the development of these complications: there was at least one survivor beyond the neonatal period in 85.1% (57/67) of pregnancies without antenatal complications, in 100% (25/25) of those complicated by sFGR and in 47.6% (20/42) of those complicated by TTTS. The overall rate of preterm birth prior to 28 weeks was 14.5% (18/124) and that prior to 32 weeks\' gestation was 49.2% (61/124).
CONCLUSIONS: Monochorionicity-related complications, which can impact adversely perinatal outcome, occur in almost half of MCTA triplet pregnancies, creating a challenge with regard to counseling, surveillance and management. © 2023 The Authors.
