How the language we speak determines the transmission of COVID-19.

BACKGROUND: Little body of research has focused on the epidemic transmissibility and language interface. AIMS: In this paper, we aim to investigate whether (i) the feature of aspiration found in the phonological inventory of several languages and (ii) the frequency of occurrence of stop consonants are associated with the transmission of COVID-19 among humans. METHODS: The study's protocol was based on a corpus of countries infected by COVID-19 and of which the linguistic repertoire includes a widely spoken language in individuals' everyday communication. We tested whether languages with and without aspiration differ in terms of COVID-19 reproduction number, and whether the frequency of occurrence of stop consonants in several languages correlates with the virus reproduction number. RESULTS: The results demonstrated no significant effect of aspiration on the transmission of the virus, while a positive correlation between the frequency of occurrence and transmissibility was observed only for the consonant /p/; this might suggest that languages that use /p/ more frequently might spread the virus more easily. CONCLUSIONS: The findings of this study can offer a tentative picture of how speaking specific sounds can be associated with COVID-19 transmissibility.

Establishing measurement properties in the assessment of inter-recti distance of the abdominal muscles in a postnatal women.

BACKGROUND: Diastasis of the rectus abdominis muscle is often evaluated in clinical practice but it is unknown which clinical method has the best measurement properties. OBJECTIVE: The aim of this study was to determine: (i) the criterion validity of the callipers, tape measure and finger-width to evaluate the inter-recti distance of the abdominal muscles compared to ultrasound; and (ii) inter-rater and retest reliability of these methods. DESIGN: Measurement study. METHODS: Two physiotherapists assessed the inter-recti distance of rectus abdominis on 50 women postnatally using the three clinical methods. These measurements were compared to ultrasound and assessed for inter-rater and retest reliability. RESULTS: Callipers had very good positive correlations with ultrasound (r = 0.85 to 0.99) and narrow limits of agreement (LOA) (<6 mm). Finger-width and tape measure had moderate to very good correlation with ultrasound (tape measure r = 0.82 to 0.98; finger-width r = 0.75 to 0.98) with wider limits of agreement (tape measure LOA <8 mm; finger-width LOA <18 mm). Callipers demonstrated excellent inter-rater (ICC = 0.80 to 0.99) and retest (ICC = 1.00) reliability. Inter-rater reliability testing was very good for tape measure (ICC = 0.80 to 0.97) and moderate to very good (ICC = 0.44 to 0.85) for finger-width. Retest reliability demonstrated very good reliability (ICC = 0.99 to 1.00) for both finger-width and tape measure. The largest inter-recti distances, strongest correlations and reliability were found at the level of the lower umbilicus. CONCLUSION: Callipers, tape measure and finger-width are valid and reliable methods of measuring inter-recti distance in postnatal women. Validity, and relative and absolute reliability were found to be the strongest using the callipers.

The impact of oral probiotics on vaginal Group B Streptococcal colonisation rates in pregnant women: A pilot randomised control study.

OBJECTIVE: To perform a pilot project to determine if this research design was appropriate to explore potential causal relationships between oral probiotic use and vaginal Group B Streptococcal (GBS) colonisation rates in pregnant women. METHOD: Thirty-four GBS-positive women at 36 weeks pregnant were recruited. The participants were randomly allocated to the control group, who received standard antenatal care, or to the intervention group, who received standard antenatal care and a daily oral dose of probiotics for three weeks or until they gave birth. A vaginal GBS swab was collected three weeks post consent or during labour. FINDINGS: No significant difference was found in vaginal GBS rates between the control and intervention groups. Only seven of 21 women in the intervention group completed the entire 21days of probiotics. A subgroup analysis, including only those who had completed 14days or more of probiotics (n=16), also showed no significant difference in vaginal GBS when compared to the control. The findings did show significantly more vaginal commensals in the probiotics group (p=0.048). DISCUSSION: Five possible reasons for the lack of significant results are: the length of the intervention was too short; the dosage of the probiotics was too low; the wrong strains of probiotics were used; the sample size was inadequate; or oral probiotics are ineffective in impacting vaginal GBS. IMPLICATIONS: The finding of a significant increase of vaginal commensals in women who completed 14days or more of probiotics supports the potential of probiotics to impact vaginal GBS in pregnancy.

Avian flu: how informed are children in Greece?

OBJECTIVES: The current cluster of avian influenza outbreaks in birds has occurred in areas where humans live in proximity to poultry. Dissemination of accurate information may be the cornerstone for proper community preparation. In the herein presented study, we attempted to asses the information level among Greek children regarding avian flu. METHODS: A descriptive study was carried out in 2006 in ten Greek prefectures to determine the information level among students about transmission ways, symptoms and prevention measures of avian flu. RESULTS: A total of 1400 Greek students participated in the study. Approximately 75% of the students reported to know what bird flu is and 53% reported to know that there has been at least one case of avian flu in Greece. More than half (55.6%) reported that an effective vaccine against avian flu does exist; of the students asked, 47% reported that avian flu can be transmitted from human to human whereas 21.4% believed that humans can suffer from avian flu. Media contribution in providing information was very high among students. CONCLUSION: The level of information about avian flu among Greek students was found inadequate especially in some questions regarding serious aspects of avian flu. This study highlights the need for adaptation of health programs in Greek schools, which should include the provision of accurate information.

Assessing the level of awareness of avian influenza among Greek students.

INTRODUCTION: Current concern regarding avian influenza, the so-called 'bird flu', concerns H5N1, a highly pathogenic avian influenza form that has spread across Asia, into Western Europe and Africa. The wide spread of bird flu makes it a serious threat to humans. A key factor in reducing the risk of an influenza pandemic is adequate preparedness, including providing prospective, accurate information to the public. In our study, we attempted to assess the level of information among Greek students aged 8 to 15 years, regarding avian influenza. METHODS: A descriptive study was carried out in 6 Greek prefectures to determine the information level regarding avian influenza among students, concerning methods of transmission, symptoms and prevention measures. RESULTS: In total, 2805 Greek students participated in the study (47% male and 53% female). Approximately 90% of the students reported knowing what 'bird flu' is, and 25% wrongly answered that there had been at least one human infection from avian influenza in Greece. Nearly half the students (46.2%) reported that an effective vaccine exists against avian influenza, and almost all the study participants (95.7%) believed that they should not touch an ill or dead bird. Forty-two per cent of the students reported that avian influenza can be transmitted from human to human, and only 11.9% believed that humans can present symptoms after being infected. The media was their main source of information. CONCLUSION: The level of information about avian influenza among Greek students was found to be satisfactory, if not ideal. These findings, along with the potential for a future avian influenza pandemic, highlight the need for intensified health education programs in Greek schools, in order to deal with this serious public health problem.
