Attitudes and barriers associated with seasonal influenza vaccination uptake among public health students; a cross-sectional study

Abstract: Although research has explored influenza vaccination uptake among medical and college students, there is a dearth of research in understanding influenza vaccination uptake and attitudes toward the vaccine among future public health practitioners Undergraduate public health students represent future public health practitioners who may be a significant educational resource for health information, including the importance of vaccinations This cross-sectional study utilized survey data from 158 undergraduate public health students attending a large public university in Southern California The survey assessed public health students’ attitudes and beliefs towards the seasonal influenza vaccine and seasonal vaccination rates among this population Over 88% of respondents reported having been encouraged to receive the seasonal influenza vaccine, while only 430% reported receipt Of the students who reported not receiving the vaccine, 494% believed it may give them the flu, 304% believed there may be dangerous side effects, and 289% believed they were not at risk for contracting the flu Access to health care practitioners (OR: 3947, 95% CI [1308–11906]) and social encouragement (OR: 3139, 95% CI [1447–6811]) were significantly associated with receipt of the seasonal influenza vaccine As public health program curriculum includes information about seasonal influenza vaccination and 68% of the sample were seniors soon to be exiting the program with an undergraduate degree in public health education, this low seasonal influenza vaccination rate is disturbing This study may add to the body of data demonstrating how knowledge of the vaccine does not always guarantee vaccine uptake Results of the current study suggest that it may be beneficial to provide additional information targeted to public health students, aimed at mediating safety concerns and increasing social pressure to assist in improving vaccine acceptance and rates in this population Maximizing seasonal influenza vaccination uptake by addressing attitudes, barriers and misperceptions may not only improve vaccination rates among public health students, but also in communities served by these future public health practitioners

Adverse Childhood Experiences and Health Indicators in a Young Adult, College Student Sample: Differences by Gender

Abstract: The original Adverse Childhood Experiences (ACE) study demonstrated strong, graded relationships between child maltreatment and household dysfunction and adult health status. The present study re-examined these relationships in a sample of young adult, college students to better characterize the developmental timing of health problems related to ACE exposure and differences by biological sex. A cross-sectional general health questionnaire that included items on ACE was administered to young adults (ages 18–29) at universities in California (n = 3880), Minnesota (n = 7708), and Texas (n = 451) between 2017 and 2018. Seven ACE were assessed: psychological, physical, or sexual abuse; violence between parents; or living with household members who were substance misusers, mentally ill, or ever imprisoned. Binary health indicators were regressed on number of ACE as 0 (referent), 1, 2, 3, and 4 or more using logistic regression controlling for age, biological sex, race/ethnicity, and site. Approximately 51.7% of the sample reported at least one ACE with a significantly higher rate among Texas participants (p < 0.001). We observed graded relationships between levels of ACE exposure and physical, mental, and behavioral health indicators including cigarette use, e-cigarette use, drinking and driving, obesity, lifetime depression, suicide ideation and attempt, non-suicidal self-injury, and lack of restful sleep. ACE-exposed females reported worse mental health status than ACE-exposed males while males reported more substance use than females. Most outcomes did not vary significantly by sex. The strong, graded relationships observed between ACE exposure and health status among young adults reinforce the need for trauma-informed intervention programs on college campuses.

Adverse Childhood Experiences, Ethnicity, and Substance Use among College Students: Findings from a Two-State Sample.

Abstract: Objectives: Despite college students reporting high rates of substance use and adverse childhood experiences (ACE), few studies have examined ACE-related substance use patterns with diverse student...

The origin of fatal pulmonary emboli: a postmortem analysis of 500 deaths from pulmonary embolism in trauma, surgical, and medical patients.

Abstract: Background The traditional theory that pulmonary emboli (PE) originate from the lower extremity has been challenged. Methods All autopsies performed in Los Angeles County between 2002 and 2010 where PE was the cause of death were reviewed. Results Of the 491 PE deaths identified, 36% were surgical and 64% medical. Venous dissection for clots was performed in 380 patients; the PE source was the lower extremity (70.8%), pelvic veins (4.2 %), and upper extremity (1.1%). No source was identified in 22.6% of patients. Body mass index (adjusted odds ratio [AOR] 1.044, 95% confidence interval [CI] 1.011 to 1.078, P = .009) and age (AOR 1.018, 95% CI 1.001 to 1.036, P = .042) were independent predictors for identifying a PE source. Chronic obstructive pulmonary disease (AOR .173, 95% CI .046 to .646, P = .009) was predictive of not identifying a PE source. Conclusions Most medical and surgical patients with fatal PE had a lower extremity source found, but a significant number had no source identified. Age and body mass index were positively associated with PE source identification. However, a diagnosis of chronic obstructive pulmonary disease was associated with no PE source identification.

MOESM3 of Current knowledge and perspectives of Paenibacillus: a review

Abstract: Isolated from a wide range of sources, the genus Paenibacillus comprises bacterial species relevant to humans, animals, plants, and the environment. Many Paenibacillus species can promote crop growth directly via biological nitrogen fixation, phosphate solubilization, production of the phytohormone indole-3-acetic acid (IAA), and release of siderophores that enable iron acquisition. They can also offer protection against insect herbivores and phytopathogens, including bacteria, fungi, nematodes, and viruses. This is accomplished by the production of a variety of antimicrobials and insecticides, and by triggering a hypersensitive defensive response of the plant, known as induced systemic resistance (ISR). Paenibacillus-derived antimicrobials also have applications in medicine, including polymyxins and fusaricidins, which are nonribosomal lipopeptides first isolated from strains of Paenibacillus polymyxa. Other useful molecules include exo-polysaccharides (EPS) and enzymes such as amylases, cellulases, hemicellulases, lipases, pectinases, oxygenases, dehydrogenases, lignin-modifying enzymes, and mutanases, which may have applications for detergents, food and feed, textiles, paper, biofuel, and healthcare. On the negative side, Paenibacillus larvae is the causative agent of American Foulbrood, a lethal disease of honeybees, while a variety of species are opportunistic infectors of humans, and others cause spoilage of pasteurized dairy products. This broad review summarizes the major positive and negative impacts of Paenibacillus: its realised and prospective contributions to agriculture, medicine, process manufacturing, and bioremediation, as well as its impacts due to pathogenicity and food spoilage. This review also includes detailed information in Additional files 1, 2, 3 for major known Paenibacillus species with their locations of isolation, genome sequencing projects, patents, and industrially significant compounds and enzymes. Paenibacillus will, over time, play increasingly important roles in sustainable agriculture and industrial biotechnology.

Distinguishing Sudden Infant Death Syndrome From Child Abuse Fatalities

Abstract: Fatal child abuse has been mistaken for sudden infant death syndrome. When a healthy infant younger than 1 year dies suddenly and unexpectedly, the cause of death may be certified as sudden infant death syndrome. Sudden infant death syndrome is more common than infanticide. Parents of sudden infant death syndrome victims typically are anxious to provide unlimited information to professionals involved in death investigation or research. They also want and deserve to be approached in a nonaccusatory manner. This clinical report provides professionals with information and suggestions for procedures to help avoid stigmatizing families of sudden infant death syndrome victims while allowing accumulation of appropriate evidence in potential cases of infanticide. This clinical report addresses deficiencies and updates recommendations in the 2001 American Academy of Pediatrics policy statement of the same name.
