AbstractStreptococcussuis (S.suis) is an important zoonotic pathogen that causes septicaemia, meningitis and streptococcal toxic shock-like syndrome in its host, and recent studies have shown that S.suis could be competent for natural genetic transformation. Transformation is an important mechanism for the horizontal transfer of DNA, but some elements that affect the transformation process need to be further explored. Upon entering the competent state, Streptococcus species stimulate the transcription of competence-related genes that are responsible for exogenous DNA binding, uptake and processing. In this study, we performed conserved promoter motif and qRT-PCR analyses and identified CrfP as a novel murein hydrolase that is widespread in S.suis and stimulated with a peptide pheromone in the competent state through a process controlled by ComX. A bioinformatics analysis revealed that CrfP consists of a CHAP hydrolase domain and two bacterial Src homology 3-binding (SH3b) domains. Further characterization showed that CrfP could be exported to extracellular bacterial cells and lytic S.suis strains of different serotypes, and this finding was verified by TEM and a turbidity assay. To investigate the potential effect of CrfP in vivo, a gene-deletion mutant (ΔcrfP) was constructed. Instead of stopping the natural transformation process, the inactivation of CrfP clearly reduced the effective transformation rate. Overall, these findings provide evidence showing that CrfP is important for S.suis serovar 2 competence.
Suspected cyanide toxicity in cattle associated with ingestion of laurel - a case report
Authors: Kennedy Aideen , Brennan Audrey , Mannion Celine , Sheehan Maresa 
Published: March 2021

Abstract
Background
Cyanide is one of the most rapidly acting toxins affecting cattle, with poisoning typically occurring following ingestion of cyanogenic plants. Laurel (Prunus laurocerasus), is one such potentially toxic cyanogenic plant. This case report details fatalities in an Irish herd following the ingestion of laurel and aims to raise awareness of the potential risk that access to laurel hedges poses to farm animals.

Case presentation
Over a twelve-day period, the death occurred of 36 dairy-cross weanlings; the majority (22 weanlings) died over a two-day period. Two days following entry to a field bounded by a laurel hedge, the weanlings displayed signs of lethargy and profuse green diarrhoea. In the majority of animals there was a limited response to treatment with antimicrobials, vitamin B complex and fluid therapy. Recumbency and death ensued. Cyanosis was noted terminally. Two weanlings were submitted for post mortem examination. Laurel leaves were identified in the rumen contents of one weanling. Post mortem findings and additional test results on cohort animals suggested a number of pathological processes may have been involved in the animals, possibly complicating/exacerbating the effects of laurel ingestion. However, cyanide was considered a factor in a least some of the casualties and arrangements were made to test for cyanide on blood samples from a random selection of seven cohort animals. Although collected one week after exposure to the laurel hedge, toxic cyanide levels were recorded in a sample from one animal, which subsequently died.

Conclusions
The large fatality rate serves as a timely reminder to include plant poisoning as a differential diagnosis when dealing with large numbers of rapid fatalities. Failure to thoroughly examine rumen contents and collect a detailed history in this case, could easily have allowed death to be attributed to other causes and the involvement of cyanide toxicity to be missed. In cases of individual or group fatalities, history is invaluable and recent entry to new grazing areas or any potential diet change or access to garden plants should be thoroughly investigated.

Abstract
Background
The Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) is commonly used in hospitals to titrate medications for alcohol withdrawal syndrome (AWS), but may be difficult to apply to intensive care unit (ICU) patients who are too sick or otherwise unable to communicate.

Objectives
To evaluate the frequency of CIWA-Ar monitoring among ICU patients with AWS and variation in CIWA-Ar monitoring across patient demographic and clinical characteristics.

Methods
The study included all adults admitted to an ICU in 2017 after treatment for AWS in the Emergency Department of an academic hospital that standardly uses the CIWA-Ar to assess AWS severity and response to treatment. Demographic and clinical data, including Richmond Agitation-Sedation Scale (RASS) assessments (an alternative measure of agitation/sedation), were obtained via chart review. Associations between patient characteristics and CIWA-Ar monitoring were tested using logistic regression.

Results
After treatment for AWS, only 56% (n = 54/97) of ICU patients were evaluated using the CIWA-Ar; 94% of patients had a documented RASS assessment (n = 91/97). Patients were significantly less likely to receive CIWA-Ar monitoring if they were intubated or identified as Black.

Conclusions
CIWA-Ar monitoring was used inconsistently in ICU patients with AWS and completed less often in those who were intubated or identified as Black. These hypothesis-generating findings raise questions about the utility of the CIWA-Ar in ICU settings. Future studies should assess alternative measures for titrating AWS medications in the ICU that do not require verbal responses from patients and further explore the association of race with AWS monitoring.
Time for a renewed focus on the role of cleaners in achieving safe health care in low- and middle-income countries
Authors: Storr Julie , Kilpatrick Claire , Lee Karen 
Published: March 2021

AbstractWater, sanitation and hygiene, collectively known as WASH, is an enabler of infection prevention and control (IPC), both of which contribute to safe, quality health care and the prevention of spread of antimicrobial resistance (AMR). This discussion paper considers the importance placed on the role of hygiene, including cleaning and those who clean, in health care facilities, within the context of existing data, guidelines and initiatives. Informed by this, the paper presents five areas for consideration that have the potential to strengthen and further demonstrate the value of this important cadre of staff and their role in clean, safe healthcare, particularly in low- and middle-income countries. The considerations centre around actions to overcome the current data gaps, including the paucity of national data on environmental cleaning and the training of cleaners; strengthening the implementation of norms and standards; combining global and national advocacy efforts; revisiting investment; and addressing research gaps on the issue. The need to act, in line with WHO and UNICEF recommendations to address this overlooked and undercompensated workforce and to elevate their status as important contributors to IPC, WASH and AMR is a pressing one.
A rapid multiclass method for antibiotic residues in goat dairy products by UPLC-quadrupole/electrostatic field orbitrap high-resolution mass spectrometry
Authors: Zhang Lu , Shi Liang , He Qiang , Li Ying 
Published: March 2021

Abstract
Background
Sulfanilamides, quinolones, nitroimidazoles, tetracyclines, cephalosporins, macrolides, and β-lactam are common tools in agriculture and can be found in animal-based foods such as goat milk and goat dried milk. To evaluate the risk of these species, reliable analytical methods are needed for accurate concentration determination, especially in goat milk and goat dried milk.

Method
We describe a method based on PRiME extraction coupled with UPLC-quadrupole/electrostatic field orbitrap high-resolution mass spectrometry to accomplish this task.

Result
Under optimal conditions, the limit of quantification for all antibiotics was 0.5–100 μg/L in goat milk and goat dried milk samples. The recoveries were 60.6–110.0% for goat milk and 60.1–109.6% for goat dried milk with a coefficient of variation less than 15%. The detection limits were 0.5–1.0 μg/kg. The limits of quantification for the analytes were 5.0–10.0 μg/kg. Finally, the method was used to screen veterinary antibiotics in 50 local goat milk and goat dried milk samples; metronidazole and enrofloxacin were detected in goat milk.

Conclusion
This method offers good reliability and the capacity for simultaneous detection can be used to detect residual contents and evaluate health risks in goat milk and goat dried milk.

Published: March 2021

Abstract
Background
Our study was designed to reveal a detailed forest fire history at Catoctin Mountain Park, Maryland, USA. We compared the ages of living trees to known fire dates in the dendrochronological record. Seasonality and years of fires in the dendrochronological record were juxtaposed with specific dates of fires recorded in newspapers.

Results
Twenty-seven pines (Pinus L.) captured 122 fire scars representing 58 distinct fire years between 1702 and 1951. Climate was significantly hotter and drier in the years of burns that affected at least two trees and was wetter two years prior. Thirty-three fires described in local newspapers were reported largely in the spring and fall months (68% between March and June, 32% between September and December). Ninety-one percent of fire scars in our tree-ring chronology had dormant seasonality. The mean fire interval was 5.47 ± 10.14 (SD; standard deviation) yr, and the Weibull median fire interval was 3.22 yr during the entire chronology. The longest fire-free interval was from 1952 to 2018.
The size structure of living trees was biased toward smaller black gums (Nyssa sylvatica Marshall) and oaks (Quercus L.) that recruited in the 1930s and 1940s. Most living pitch pines (Pinus rigida Mill) recruited between 1890 and 1910, but a few individuals recruited before the 1850s. Diversity of tree stems smaller than 10 cm diameter at breast height (DBH) was generally lacking; the youngest tree >10 cm DBH in our study area had recruited by 1967.

Conclusions
The Catoctin Mountains experienced frequent fire during the 1800s and early 1900s. The causes of fires were diverse, including accidental ignitions and purposeful cultural burning for berry (Vaccinium L.) production. The current forest developed during a period of low deer density and after the demise of the charcoal iron industry ended an era of logging. The lack of fire since the 1950s has encouraged the development of a black gum dominated mid- and understory. Management with frequent fire would facilitate pine and oak regeneration.

Published: March 2021

PURPOSE: Patients have been increasingly using physician-rating websites (PRWs); however, few studies have analyzed the validity of star ratings on PRWs. We aimed to compare PRW patient satisfaction scores with internally generated patient satisfaction scores (internal scores) of physicians at a large quaternary cancer center. METHODS: We collected internal scores and PRW scores for physicians at MD Anderson Cancer Center. Internal scores were based on patient responses to the Clinician and Group Consumer Assessment of Healthcare Providers and Systems patient experience (CG-CAHPS) survey. Only physicians with an internal score on the basis of ≥ 30 patient reviews were included. The median numbers of reviews and median scores were compared between internal data and four PRWs (Google, HealthGrades, Vitals, and WebMD). Both internally and on PRWs, possible scores ranged from 1 (least satisfied) to 5 (most satisfied). RESULTS: Of 640 physicians with an internal score, 510 (79.7%) met the inclusion criteria. For these 510 physicians, the median (IQR) number of internal reviews was 49.5 (30-93) and the median (IQR) internal score was 4.89 (4.81-4.93); the median number of reviews on PRWs ranged from 2 to 7, and the median score on PRWs ranged from 4.40 to 5.00. No physician had an internal score < 4, but the proportions with score < 4 on PRWs ranged from 16% to 30%. CONCLUSION: Internal patient satisfaction scores were higher and calculated from more reviews than PRW patient satisfaction scores and correlated weakly with PRW scores. Given that patients rely on PRWs when evaluating potential physicians, we recommend publishing internal scores online to give patients more complete information regarding physician performance.
Predictors and Acceptability of Shared Physical Activity Participation in Parent–Child Dyads

Published: March 2021

ABSTRACT
Shared physical activity (PA) in children and their parents is an approach to increase PA participation for both children and adults. Understanding variables associated with shared PA is essential to inform effective, tailored PA interventions for families. The purpose of this study was to identify predictors and to assess the acceptability of shared PA in parent–child dyads. Each parent–child dyad (n = 31; mean ± SD age, parents: 38.0 ± 6.6 yr, children: 5.9 ± 1.7 yr) was guided through five standardized PAs (brisk walking, jumping games, body-weight exercises, dancing, and tag games) at a research fitness center. Parents reported demographic characteristics and PA-related variables (i.e., PA self-efficacy, family chaos, and annual household income). One week later, parents (n = 28) reported their dyad’s weekly minutes spent in shared PA. A forward selection procedure was used to determine the optimal regression model for predicting minutes of shared PA. McNemar’s tests were used to determine the dyad’s acceptability of each shared PA. Lower family chaos (β = −19.41, P = 0.034), higher parent body mass index (β = 7.65, P = 0.003), and higher annual household income (β = 11.85, P = 0.023) predicted minutes of shared PA. Jumping games, body-weight exercises, dancing, and tag games were not acceptable for parent–child dyads to participate in together (P < 0.05). Brisk walking was an acceptable shared PA (P = 0.125). Lower family chaos, higher parent body mass index, and higher annual household income predicted shared PA. Brisk walking was an acceptable PA for parent–child dyads to participate outside of a research laboratory setting. These results can aid future PA programs that include children and parents together.
An exploratory study of social media users’ engagement with COVID-19 vaccine-related content
Authors: Al-Zaman Md. Sayeed 
Published: March 2021

Background: Facebook, as the world’s most popular social media platform, has been playing various important roles throughout the COVID-19 pandemic, allowing users to produce and share health-related information that both eases and complicates public health communication. However, the characteristics of vaccine-related Facebook content and users’ reaction to the vaccine issue has been an unexplored area to date. Methods: To fill the previous knowledge-gap, this exploratory study wants to understand the communication climate of Facebook on the COVID-19 vaccine issue, including the nature of dominant content and users’ engagement patterns with them. Therefore, the study analyzes the 10,000 most popular Facebook posts with the highest interactions on the vaccine issue. Results: The results show that Facebook users prioritize more vaccine-related news links (71.22%) over other content. The declining interactions on the issue suggests that interaction growth mainly depends on positive news on the vaccine. Finally, users’ reaction to the vaccine issue is dominantly positive, though they may show a highly negative attitude toward vaccine misinformation. Conclusions: A few limitations and strengths of this study are discussed along with values and implications. This study for the first time analyzes Bangla language-based Facebook content related to the COVID-19 vaccine issue, which is largely overlooked in global academic research.
Fitness costs of individual and combined pyrethroid resistance mechanisms, kdr and CYP-mediated detoxification, in Aedes aegypti
Authors: Smith Letícia B. , Silva Juan J. , Chen Connie , Harrington Laura C. , Scott Jeffrey G. 
Published: March 2021

Background
Aedes aegypti is an important vector of many human diseases and a serious threat to human health due to its wide geographic distribution and preference for human hosts. A. aegypti also has evolved widespread resistance to pyrethroids due to the extensive use of this insecticide class over the past decades. Mutations that cause insecticide resistance result in fitness costs in the absence of insecticides. The fitness costs of pyrethroid resistance mutations in A. aegypti are still poorly understood despite their implications for arbovirus transmission.

Methodology/Principle findings
We evaluated fitness based both on allele-competition and by measuring specific fitness components (i.e. life table and mating competition) to determine the costs of the different resistance mechanisms individually and in combination. We used four congenic A. aegypti strains: Rockefeller (ROCK) is susceptible to insecticides; KDR:ROCK (KR) contains only voltage-sensitive sodium channel (Vssc) mutations S989P+V1016G (kdr); CYP:ROCK (CR) contains only CYP-mediated resistance; and CYP+KDR:ROCK (CKR) contains both CYP-mediated resistance and kdr. The kdr allele frequency decreased over nine generations in the allele-competition study regardless of the presence of CYP-mediated resistance. Specific fitness costs were variable by strain and component measured. CR and CKR had a lower net reproductive rate (R0) than ROCK or KR, and KR was not different than ROCK. There was no correlation between the level of permethrin resistance conferred by the different mechanisms and their fitness cost ratio. We also found that CKR males had a reduced mating success relative to ROCK males when attempting to mate with ROCK females.

Conclusions/Significance
Both kdr and CYP-mediated resistance have a fitness cost affecting different physiological aspects of the mosquito. CYP-mediated resistance negatively affected adult longevity and mating competition, whereas the specific fitness costs of kdr remains elusive. Understanding fitness costs helps us determine whether and how quickly resistance will be lost after pesticide application has ceased.

Background
Chagas disease (CD) is a chronic parasitic disease caused by Trypanosoma cruzi and is endemic to continental Latin America. In Spain, the main transmission route is congenital. We aimed to assess adherence to regional recommendations of universal screening for CD during pregnancy in Latin American women in the province of Alicante from 2014 to 2018.

Methodology/Principal findings
Retrospective quality study using two data sources: 1) delivery records of Latin American women that gave birth in the 10 public hospitals of Alicante between January 2014 and December 2018; and 2) records of Chagas serologies carried out in those centers between May 2013 and December 2018. There were 3026 deliveries in Latin American women during the study period; 1178 (38.9%) underwent CD serology. Screening adherence ranged from 17.2% to 59.3% in the different health departments and was higher in Bolivian women (48.3%). Twenty-six deliveries (2.2%) had a positive screening; CD was confirmed in 23 (2%) deliveries of 21 women. Bolivians had the highest seroprevalence (21/112; 18.7%), followed by Colombians (1/333; 0.3%) and Ecuadorians (1/348; 0.3%). Of 21 CD-positive women (19 Bolivians, 1 Colombian, 1 Ecuadorian), infection was already known in 12 (57.1%), and 9 (42.9%) had already been treated. Only 1 of the 12 untreated women (8.3%) was treated postpartum. Follow-up started in 20 of the 23 (87.0%) neonates but was completed only in 11 (47.8%); no cases of congenital transmission were detected. Among the 1848 unscreened deliveries, we estimate 43 undiagnosed cases of CD and 1 to 2 undetected cases of congenital transmission.

Conclusions/Significance
Adherence to recommendations of systematic screening for CD in Latin American pregnant women in Alicante can be improved. Strategies to strengthen treatment of postpartum women and monitoring of exposed newborns are needed. Currently, there may be undetected cases of congenital transmission in our province.
