This work aimed to characterize, identify, and determine the deteriorating potential of the contaminating psychrotrophic bacteria in refrigerated raw milk. Samples were submitted to serial dilutions and plated in specific culture media to form a bacterial culture collection. The isolates were characterized for their morphology and biochemical characteristics. The deteriorating potential of the isolates was determined according to the proteolytic, lipolytic and lecithinase activities at 4.0 ºC, 6.5 ºC, and 25.0 ºC. The results obtained for deterioration potential were assessed by the multivariate statistical method and by the principal components analysis (PCA). A total of 159 isolates were characterized, and of these, 46 strongly proteolytic Gram-negative isolates were selected for identification using the API 20 NE kit. The predominant bacteria were Gram-negative and oxidase and catalase positive, with a predominance of bacteria of the genus Pseudomonas. Using PCA, it was shown that the bacteria with the greatest deterioration potential were lecithinase producers, and that, in the autumn, proteolytic bacteria predominated at 4.0 ºC. Of the 46 isolates identified, more than 80% belonged to the species Pseudomonas fluorescens. Thus, attention should be given to the importance of implementing microbial contamination prevention measures in the bulking process, since, even under refrigeration, psychrotrophic bacteria multiply and produce enzymes that deteriorate lipids and proteins, with consequent quality losses of the milk and its derivatives, yield losses in the production of dairy products, and economic losses.

Coronavirus disease 2019 (COVID-19) has dramatically changed people’s behavior, to prevent infection and overcome the general adversity caused by the implementation of infection-prevention measures. Here, we investigated the main coping-behavior and risk-perception factors, and the underlying psychological mechanisms (e.g., psychobehavioral characteristics) of coping behavior. We recruited 2,885 Japanese participants (1,524 women, ages 20–91 years). First, we identified four coping-behavior factors (two related to infection and two related to general adversity) and three risk-perception factors (one related to medical aspects and two related to society). Second, we demonstrated that infection prevention was promoted by female sex and etiquette in the Power to Live scale. General-adversity coping behavior was facilitated by shortages of daily necessities. Thus, we identified four parsimonious coping-behavior factors, as well as the risk-perception factors and demographic and psychobehavioral characteristics that influenced them. These results will benefit strategic approaches to optimize the social response to the pandemic.

AbstractThe purpose of this scoping review is to establish the state of the art on economic evaluations in the field of HIV/STI prevention in high-income countries with concentrated epidemic settings and to assess what we know about the cost-effectiveness of different measures. We reviewed economic evaluations of HIV/STI prevention measures published in the Web of Science and Cost-Effectiveness Registry databases. We included a total of 157 studies focusing on structural, behavioural, and biomedical interventions, covering a variety of contexts, target populations and approaches. The majority of studies are based on mathematical modelling and demonstrate that the preventive measures under scrutiny are cost-effective. Interventions targeted at high-risk populations yield the most favourable results. The generalisability and transferability of the study results are limited due to the heterogeneity of the populations, settings and methods involved. Furthermore, the results depend heavily on modelling assumptions. Since evidence is unequally distributed, we discuss implications for future research.

Maritime ports are critical logistics hubs that play an important role when preventing the transmission of COVID-19-imported infections from incoming international-going ships. This study introduces a data-driven method to dynamically model infection risks of international ports from imported COVID-19 cases. The approach is based on global Automatic Identification System (AIS) data and a spatio-temporal clustering algorithm that both automatically identifies ports and countries approached by ships and correlates them with country COVID-19 statistics and stopover dates. The infection risk of an individual ship is firstly modeled by considering the current number of COVID-19 cases of the approached countries, increase rate of the new cases, and ship capacity. The infection risk of a maritime port is mainly calculated as the aggregation of the risks of all of the ships stopovering at a specific date. This method is applied to track the risk of the imported COVID-19 of the main cruise ports worldwide. The results show that the proposed method dynamically estimates the risk level of the overseas imported COVID-19 of cruise ports and has the potential to provide valuable support to improve prevention measures and reduce the risk of imported COVID-19 cases in seaports.

В работе рассматриваются результаты авторского социологического исследования, проведённого в мае 2021 г. Опрос был проведен среди студентов, обучающихся в медицинском институте ФГБОУ ВО «Майкопский государственный технологический университет» («МГТУ»), с целью изучения отношения студенческой молодежи к необходимости соблюдения мер профилактики коронавирусной инфекции, а также к вакцинации населения и отношения к ним студентов медицинских специальностей в период локдауна и после него. Результаты проведённого исследования показали высокую степень ответственности студентов - будущих медиков за своё здоровье и здоровье окружающих. В то же время часть опрошенных демонстрировала в этот период нигилизм по отношению к мерам профилактики COVID-19. Вместе с тем участники опроса продемонстрировали высокий уровень толерантности по отношению к студентам - гражданам других государств, обучающимся вместе с ними. Ответы студентов медицинских специальностей на вопросы анкеты показывают понимание параметрики, смысла и содержания ограничений, введённых в период пандемии, и необходимости соблюдения жителями региона мер, рекомендованных Роспотребнадзором для профилактики и нераспространения коронавирусной инфекции. The work examines the results of the author's sociological study conducted in May 2021. The survey was conducted among students learning at the Medical Institute of the Maykop State University of Technology in order to study the attitude of students to the need to comply with measures to prevent coronavirus infection, as well as to vaccinate the population and the attitude of medical students to them during the lockdown period and after it. The results of the study showed a high degree of responsibility of students - future medical experts for their health and that of others. At the same time, some respondents demonstrated nihilism towards COVID-19 prevention measures during this period. At the same time, the survey participants showed a high level of tolerance towards students - citizens of other states studying with them. The answers of medical students to the questions of the questionnaire show an understanding of the parameters, meaning and content of the restrictions introduced during the pandemic, and the need for residents of the region to comply with the measures recommended by Rospotrebnadzor for the prevention and non-proliferation of coronavirus infection.

Background: Injury and illness surveillance in sports is the first step of the injury prevention model that generates effective injury prevention measures. Objectives: To identify the incidence, severity, and causes of injuries and illness in the Thailand national team during the 30th Southeast Asian (SEA) Games. Methods: All medical encounters were documented using the International Olympic Committee (IOC) injury and illness surveillance system for multi-sport events. We recorded the daily occurrence of injuries and illnesses reported by Thailand’s medical teams over the 12 days of the competition period. Results: Among 980 Thai athletes (568 male and 412 female), that participated in the 30th SEA Games, a total of 105 injuries and illnesses were reported. There were 84 injuries and 21 illnesses which equated to an incidence of 86 injuries and 21 illnesses per 1000 athletes. The most commonly injured body part was the lower leg (14% of all injuries), followed by the shoulder and clavicle. Ligament sprain or rupture and contusion (25% of all injuries) were reported as the most common type of injury. Of all injuries, 56 were classified as needing medical attention (only), 26 caused performance restriction, and two caused complete-time loss. The most common athlete illness was respiratory illness (48% of all illnesses) followed by gastrointestinal illness (19% of all illnesses). One-third (7 out of 21) of athlete illnesses restricted the athlete's performance, and the remaining 14 only required medical attention. Conclusions: Overall, 8% of athletes incurred at least one injury during the competition, and 2% suffered from an illness. Lower leg injury and respiratory illness were the most common, which is similar to other multi-sport events. Based on the research data, injury prevention, especially of ligamentous sprain and lower limb injuries, should be the focus in multi-sport events.

Within Organization for Economic Cooperation and Development (OECD) nations, South Korea has the highest suicide rate for which immediate prevention measures are sought including effective therapeutic counseling interventions. As such, the present study explored and examined experienced South Korean counselors' perception of therapeutic interventions for the prevention or delaying of completed suicide, using concept mapping methodology. The semi-structured interviews were provided to 15 study participants of experienced counselors having a minimum of 5 years of professional counseling career and at least 10 suicide crisis counseling sessions. A total of 77 statements were extracted with 8 major clusters: “Securing Safety,” “Active Advocacy for Client,” “Coping Skills Training,” “Conceptualization of Suicide Crisis,” “Emotional Identification and Validation,” “Empowerment,” “Counselor Self-Disclosure,” “Counselor Self-Awareness and Regulation.” From the results, the present study described unique findings in Korean counselors' perceptions of suicide crisis therapeutic intervention. Study limitations and future implications are further discussed.

The global impact of coronavirus disease 2019 (COVID-19) is unprecedented, and many control and prevention measures have been implemented to test for and trace COVID-19. However, invisible-spreaders, who are associated with nucleic acid detection and asymptomatic infections, have received insufficient attention in the current COVID-19 control efforts. In this paper, we analyze the time series infection data for Italy, Germany, Brazil, India and Sweden since the first wave outbreak to address the following issues through a series of experiments. We conclude that: 1) As of June 1, 2020, the proportion of invisible-spreaders is close to 0.4% in Sweden, 0.8% in early Italy and Germany, and 0.4% in the middle and late stages. However, in Brazil and India, the proportion still shows a gradual upward trend; 2) During the spread of this pandemic, even a slight increase in the proportion of invisible-spreaders could have large implications for the health of the community; and 3) On resuming work, the pandemic intervention measures will be relaxed, and invisible-spreaders will cause a new round of outbreaks.

Due to structural irregularity, curved bridgesaremore likely to cause non-uniform collisions and unseating between adjacent components when subjected to earthquakes. Based on the analysis of the collision response of curved bridges duringearthquakes, and according to the seismic characteristics of curved bridges, research was carried out on pounding mitigation and unseating prevention measures. A curved bridge with double column piers was taken as an engineering example, and a finite element model of curved bridges thatcould consider the non-uniform contact collision between adjacent components was built with ABAQUS software. Viscoelastic dampers, viscous dampers, and a lead rubber bearing were selected as the damping devices, and a steel wire rope-rubber mat was used as the pounding mitigation device to form the combinatorial seismic mitigation system. Based on the principle of energy dissipation combined with constraints, three kinds of combined seismic mitigation case were determined; a seismic response analysis was then performed. The results indicated that the three kinds of combined seismic case were effective atreducing the response topounding force, stress, damage, girder torsion and displacement, and achieved the goals of seismic mitigation and unseating prevention.

Abstract Introduction: Japan recently experienced two major heavy rain disasters: the West Japan heavy rain disaster in July 2018 and the Kumamoto heavy rain disaster in July 2020. Between the occurrences of these two disasters, Japan began experiencing the wave of the coronavirus disease 2019 (COVID-19) pandemic, providing a unique opportunity to compare the incidence of acute respiratory infection (ARI) between the two disaster responses under distinct conditions. Sources for Information: The data were collected by using the standard disaster medical reporting system used in Japan, so-called the Japan-Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED), which reports number and types of patients treated by Emergency Medical Teams (EMTs). Data for ARI were extracted from daily aggregated data on the J-SPEED form and the frequency of ARI in two disasters was compared. Observation: Acute respiratory infection in the West Japan heavy rain that occurred in the absence of COVID-19 and in the Kumamoto heavy rain that occurred in the presence of COVID-19 were responsible for 5.4% and 1.2% of the total consultation, respectively (P <.001). Analysis of Observation and Conclusion: Between the occurrence of these two disasters, Japan implemented COVID-19 preventive measures on a personal and organizational level, such as wearing masks, disinfecting hands, maintaining social distance, improving room ventilation, and screening people who entered evacuation centers by using hygiene management checklists. By following the basic prevention measures stated above, ARI can be significantly reduced during a disaster.
