Context Adverse childhood experiences (ACEs) negatively impact health outcomes later in life, in a dose–dependent relationship; however, little is known about the impact of the individual ACE categories and subjective cognitive decline (SCD) later in life. Objectives The aim of this study was to determine the associations among the eight ACEs and SCD. Methods We analyzed data from two cycles of the Behavioral Risk Factor Surveillance System (BRFSS; 2019–2020). We assessed the accumulation of ACEs and their association with SCD, and among individuals reporting only one ACE, we utilized logistic regression to compare the likelihood of reporting SCD and symptomology among the eight categories of adversity. Results Among included respondents, 10.14% reported experiencing SCD. More ACEs were reported among those with SCD (mean, 2.61; SD, 2.56) compared to those without SCD (mean, 1.44; SD, 1.91). Those with higher ACE scores were significantly less likely to have spoken with a healthcare provider about their cognitive decline. Individuals reporting one ACE of either family mental illness, family substance abuse, family incarceration, emotional abuse, or physical abuse had significantly greater odds of reporting memory loss compared to individuals with no ACEs. Conclusions Having multiple ACEs was significantly associated with higher odds of SCD and associated limitation of social activity and was inversely associated with getting help when it is needed. Further, many ACE categories were associated with SCD – a novel addition to the literature and the methodology utilized herein. Interventions focused on improving cognitive health and preventing cognitive decline should consider the potential role of ACEs among affected populations.

Context One of the two major pathways to become a physician in the United States is the Doctor of Osteopathic Medicine (DO) degree. A major distinctive feature is often perceived as the addition of manual training in osteopathic manipulative treatment (OMT) in the DO education. However, the profession also has a distinct philosophy imbedded in the curriculum of all osteopathic medical schools. Many medical schools offer professional degrees with graduates who may choose to continue their education in medicine, such as the Master of Science in Biomedical Sciences (MSBS). At our institution, there is no formal exposure to the differences between osteopathic and allopathic medicine in the MSBS curriculum, and most of this understanding is gained through out-of-classroom conversations. During the SARS-CoV-2 pandemic, virtual learning prohibited the usual gathering and discourse that occurs when students are learning on campus. Objectives The objective of this study is to create a curriculum in the form of a seminar series to assist premedical students in making an informed choice about which profession is the best fit for their own education and to gain an appreciation for osteopathic medicine. This appreciation could also aid in the future collaboration of premedical students with osteopathic providers, recommendations to patients, and potentially their own medical care. Questionnaires were utilized to determine if our osteopathic seminar series was effective at changing the preferences and understanding of MSBS students. We also sought to determine the effectiveness of virtual vs. in-person delivery of our curriculum. Methods A seminar series with pre-established objectives was developed and presented to MSBS students at an osteopathic institution during the Fall of 2020 and 2021. The 2020 seminar was delivered through a virtual conference platform, and the 2021 seminar was delivered in-person. An eight question pre-and postquestionnaire was given to participants to evaluate their preferences and understanding. Internal validity and differences between delivery formats were assessed. Results Both seminar series produced equally effective, significant changes in the preferences and perceptions of osteopathic medicine in both virtual and in-person delivery formats. Differences in pre-vs. post understanding across both seminar series were not consistently significant and were smaller than those observed in preferences and perceptions. Positive changes included an increased willingness to see a DO and to recommend a loved one see a DO as their personal physician. Preference changes between the in-person vs. virtual delivery platforms did not show significant differences; however, understanding did show some inconsistent differences. Conclusions This study demonstrates the utility of a virtual or in-person seminar to improve the preferences and perceptions of the osteopathic profession in MSBS students. The seminar series was successful in its goal of offering formal exposure to the osteopathic profession. The improved preferences and perceptions will have potential substantial benefits to the field of osteopathic medicine in the future. Further research is warranted to determine the most effective way to increase understanding of the osteopathic profession.

Context There is a common symptom pattern with most chronic low back pain (CLBP), suggesting that there is a common underlying etiology, belying the term “nonspecific.” Many studies of CLBP and its treatment have been conducted with the assumption of nonspecificity, and as a result, treatment has not been focused, thus there has not been a significant change in CLBP prevalence over the past several decades. It is the thesis of this study to show that there is an underlying, specific cause of CLBP and that the presumption that CLBP is nonspecific is misdirected. The lumbosacropelvic (LSP) region, including the sacroiliac joint (SIJ), is part of a neuromusculoskeletal (NMSK) feedback system, and it is proposed here that CLBP is the result of a change in the feedback (afferent) aspect in that system. Objectives The objectives of this study are to show that CLBP presents as a pattern of symptoms that actually represents the final common pathway for a dysfunctional LSP joint system. Rather than being “nonspecific,” the majority of CLBP has an underlying cause that is quite specific and predictable. Methods A total of 252 patients were seen for CLBP, 67% of whom were diagnosed with an SIJ dysfunction. The presence of pain was recorded from seven structures most closely associated with CLBP. The conditional probabilities of having each pain generator given a SIJ dysfunction and an SIJ dysfunction given the presence of the pain generator were estimated, and associations were analyzed utilizing chi-square tests. Phi coefficients and odds ratios were utilized to quantify the strength of the association. The multivariable logistic regression model was fit to relate the presence or absence of the SIJ dysfunction to the seven pain generators. Results The associations between SIJ dysfunction and each pain generator were statistically significant. Phi coefficients indicated moderate strengths of these bivariate associations. Iliolumbar ligament (ILL) and psoas muscle (PSM) were significant predictors of SIJ dysfunction in the multivariable model. Conclusions Seven pain generators had a strong association with SIJ dysfunction. This empirical clinical evidence supports our hypothesis that LSP system dysfunction, as evidenced by SIJ dysfunction, is a common source of symptom patterning associated with CLBP and is most likely the causal element. This is evidence that most CLBP is not “nonspecific” but rather the result of changes made by the NMSK control system for the LSP region.

Context The mechanisms by which osteopathic cranial manipulative medicine (OCMM) promotes health and healing have yet to be fully elucidated. One commonly utilized OCMM technique, compression of the fourth ventricle (CV4), has been theorized to balance autonomic nervous system (ANS) activity. There is growing evidence that the ANS also plays a significant mechanistic role in acupuncture. Potential connections between OCMM and acupuncture meridian theory largely remain unknown. Objectives By measuring specific electrical parameters at acupuncture points that have been shown to correlate with ANS activity, the objectives of this study were to: 1) determine if CV4 has any influence on the bioelectric properties of the acupuncture meridian system; and 2) determine if CV4 affects the ANS. Methods A total of 77 males and females ages 18–78 years, all volunteers recruited by local flyers and personal or phone contact, were randomized into CV4 (n=40) and Sham (n=37) groups. All CV4 participants were treated by the same physician utilizing standard CV4 protocol. The Sham treatment, performed by a different physician, consisted of the supine participant’s occiput resting passively on the physician’s finger pads for a similar duration as those in the CV4 group. Among several devices developed to assess ANS activity at acupuncture points, evidence suggests that the Apparatus for Meridian Identification (AMI) is the most accurate and valid. Utilizing the AMI, bioelectric skin parameters were measured immediately before and after CV4 or Sham treatments. Student’s or Welch’s t tests and Wilcoxon tests were utilized for analysis of normally and non-normally distributed data, respectively. Results Statistical significance was determined with a p value less than 0.05. Sham treatments showed insignificant (p=0.754) before vs. after differences in ANS activity measured at acupuncture points, whereas CV4 treatment significantly (p=0.00015) affected ANS activity. Conclusions This research suggests that CV4 has demonstrable biophysical effects on the acupuncture meridian system occurring via the ANS, and that the underlying mechanisms of OCMM and acupuncture may be related. Further studies are needed to clarify this.

Context Environmental exposures are associated with approximately 19% of disease globally, and exposure to neurotoxic chemicals is estimated to cost the United States $50 billion per year. Despite calls from the Institute of Medicine to increase training for clinicians regarding environmental health since the 1990s, there is still little instruction in environmental health for clinicians. This leaves gaps in knowledge that need to be bridged through outreach and education to practicing clinicians. Academic detailing (AD) is an educational intervention associated with improved prescribing practices in healthcare professionals but has not been applied to preventive or environmental health. Childhood lead exposure is a common condition associated with lifetime increased risk of cognitive and behavioral problems. Ohio has more than 2 million homes built before 1978, making exposure to lead-based paint a significant public health problem; however, only 50% of high-risk children are tested for lead. Few receive health promotion information regarding lead poisoning prevention, in part because this is not a part of training for healthcare providers (HCPs). Objectives The objectives of this study were twofold: (1) implement a pilot of AD sessions on the topic of childhood lead poisoning prevention with frontline HCPs and their staff in different practice settings; and (2) evaluate the acceptability of these training sessions utilizing quantitative and qualitative methods. Methods Physicians, nurses, social workers, community health workers, and clinical office staff were recruited from clinics who care for children at high risk for lead exposure. Trainings consisting of small group AD style sessions were presented at these sites. Learning objectives included increasing knowledge regarding lead testing requirements, enabling identification of lead’s impact on child development and equipping participants to provide anticipatory guidance for parents regarding lead poisoning prevention. Participants provided feedback through an anonymous questionnaire and qualitative feedback. Results There were 46 participants (12 physicians in practice/in training, 21 nursing or office staff, and 13 community health or social workers); more than 90% of the participants reported that the training achieved its learning objectives. Small-group presentations were preferred (91%); approximately 39% of participants requested an online format. Participants preferred that the presenters be either a public health or lead clinical expert, and they suggested that future activities include clinical vignettes. Conclusions Academic-detailing style training shows promise in promoting childhood lead poisoning prevention for frontline HCPs.

Context Mask wearing to mitigate the spread of COVID-19 and other viral infections may raise concerns on the effects of face masks on breathing and cardiopulmonary health. Non–evidence-based apprehensions may limit the use of masks in public. Objectives We will assess the parameters related to heart and lung physiology between healthy male and female adults exposed to wearing face masks (or not) under conditions of rest and graded exercise. Methods We performed a cross-sectional study including 20 male and 20 female adults who met our inclusion criteria. Adults with underlying respiratory and cardiac conditions were excluded. Physiologic parameters were measured while the participants underwent three activity levels (10 min each) in a randomly assigned order: rest, walking, and stair climbing. Each activity level was conducted under three mask conditions: no mask, surgical mask, and N95 respirator. Heart rate (HR) and blood oxygen saturation (SpO 2 ) were recorded via pulse oximeter after each activity. Perceived exertion was recorded utilizing a Borg 15-point scale. A mixed-effects analysis of variance (ANOVA) was utilized to interpret the results. Results A significant increase in perceived exertion was reported for N95 users (p<0.0001). There was also a significant increase in mean HR for N95 users in comparison to no-mask users (p=0.0031). The mean SpO 2 in females was higher than males under rest and walking conditions (p=0.0055). There was no change in SpO 2 between mask type overall, nor between mask type vs. exercise intensity, nor between mask type and sex. Conclusions Our findings provide evidence that surgical masks and N95 respirators do not influence SpO 2 at rest or during exercise.
