Healers and midwives accused of witchcraft (1563-1736) - What secondary analysis of the Scottish survey of witchcraft can contribute to the teaching of nursing and midwifery history.

BACKGROUND: Nearly 4000 people were accused of witchcraft in Scotland between 1563 and 1736. Some of these were healers, midwives, and nurses. OBJECTIVE: To investigate Scotland's folk-healers and midwives accused of witchcraft and review their work from a nursing and midwifery perspective. DESIGN: Secondary analysis of the Survey of Scottish Witchcraft. METHODS: Those on the Survey with witchcraft accusations relating to folk-healing or midwifery were identified and their biographies were created from Survey data (2021). Individual biographical data were descriptively analysed. Healing/midwifery practice information was tabulated and thematically analysed. RESULTS: 142 individuals were identified (85 % women), 51 % were found guilty, 90 % were executed. Most (98 %) were folk-healers with 10 accused for midwifery reasons. Mainly their work was accused of causing harm. Three themes emerged: their use of rituals; unorthodox religious practices and treatments. Rituals included actions carried out a certain number of times. Religious practices frequently referenced Catholicism. Many of their treatments for ingestion, application or bathing used items still recognised for their health properties. Approximately, 10 % of the 142, mainly in the 1500s/early 1600s, utilised expensive items and complex treatments which had more in common with 'elite' knowledge rather than simple folklore. CONCLUSIONS: Across all 142 people, many aspects of their work are identifiable within more contemporary nursing and midwifery practice including their use of rituals, treatments, and holism. Mostly the accused were folk-practitioners, but a few (1500s/early 1600s) appear to have been healers working akin to physicians. Following the Protestant reformation (1560) their work, unlike that of physicians, was marginalised, considered unorthodox and harmful because they were women and/or their work reflected Catholicism. European hospital nursing originates in the monastic houses, but little is known about these early religious nurses. This study is novel in suggesting that whoever taught these accused witch/healers may have been connected to the monastic hospitals pre-Reformation.

A hidden infection: Racemose neurocysticercosis causing hydrocephalus; a case report.

INTRODUCTION AND IMPORTANCE: Neurocysticercosis (NCC) is the most common helminthic central nervous system infection (CNS) in the Western hemisphere and the most common cause of acquired epilepsy worldwide. Due to its relatively prolonged latent period and clinical similarity to other infectious diseases - including bacterial or viral meningitis and other helminthic infections - NCC may be difficult to diagnose, especially for clinicians who rarely encounter it. CASE PRESENTATION: This case report discusses a patient with obstructive hydrocephalus and eosinophilic meningitis secondary to racemose NCC. The diagnosis process was initially complicated by the patient's history of pork allergy and absence of radiographic evidence of helminthic CNS infection. Further investigation showed a 4th ventricle multi-cystic lesion causing hydrocephalus which prompted a surgical intervention with a ventriculoperitoneal shunt (VPS) in conjunction with anti-helminthic medical treatment. At 1-year follow-up, the patient has reported recurrence of VPS related complications. CLINICAL DISCUSSION: Larval cysts typically deposit within the brain parenchyma, making them easily detected on head computed tomography (CT) scans and leading to neurologic sequelae such as epilepsy. In this case, the absence of CT evidence of NCC and the patient's lifelong history of pork allergy slowed the diagnosis process. CONCLUSION: Racemose NCC is a rare subset of the disease in which cyst clusters occupy the extra parenchymal space, thereby changing the symptomatic profile and making the cysts more difficult to visualize in imaging studies. In this case, magnetic resonance imaging (MRI) was the best imaging modality to diagnosis extra parenchymal NCC and guide its surgical management.

Intra-articular MMP-1 in the spinal facet joint induces sustained pain and neuronal dysregulation in the DRG and spinal cord, and alters ligament kinematics under tensile loading.

Chronic joint pain is a major healthcare challenge with a staggering socioeconomic burden. Pain from synovial joints is mediated by the innervated collagenous capsular ligament that surrounds the joint and encodes nociceptive signals. The interstitial collagenase MMP-1 is elevated in painful joint pathologies and has many roles in collagen regulation and signal transduction. Yet, the role of MMP-1 in mediating nociception in painful joints remains poorly understood. The goal of this study was to determine whether exogenous intra-articular MMP-1 induces pain in the spinal facet joint and to investigate effects of MMP-1 on mediating the capsular ligament's collagen network, biomechanical response, and neuronal regulation. Intra-articular MMP-1 was administered into the cervical C6/C7 facet joints of rats. Mechanical hyperalgesia quantified behavioral sensitivity before, and for 28 days after, injection. On day 28, joint tissue structure was assessed using histology. Multiscale ligament kinematics were defined under tensile loading along with microstructural changes in the collagen network. The amount of degraded collagen in ligaments was quantified and substance P expression assayed in neural tissue since it is a regulatory of nociceptive signaling. Intra-articular MMP-1 induces behavioral sensitivity that is sustained for 28 days (p < 0.01), absent any significant effects on the structure of joint tissues. Yet, there are changes in the ligament's biomechanical and microstructural behavior under load. Ligaments from joints injected with MMP-1 exhibit greater displacement at yield (p = 0.04) and a step-like increase in the number of anomalous reorganization events of the collagen fibers during loading (p ≤ 0.02). Collagen hybridizing peptide, a metric of damaged collagen, is positively correlated with the spread of collagen fibers in the unloaded state after MMP-1 (p = 0.01) and that correlation is maintained throughout the sub-failure regime (p ≤ 0.03). MMP-1 injection increases substance P expression in dorsal root ganglia (p < 0.01) and spinal cord (p < 0.01) neurons. These findings suggest that MMP-1 is a likely mediator of neuronal signaling in joint pain and that MMP-1 presence in the joint space may predispose the capsular ligament to altered responses to loading. MMP-1-mediated pathways may be relevant targets for treating degenerative joint pain in cases with subtle or no evidence of structural degeneration.

Intra-articular collagenase in the spinal facet joint induces pain, DRG neuron dysregulation and increased MMP-1 absent evidence of joint destruction.

Degeneration is a hallmark of painful joint disease and is mediated by many proteases that degrade joint tissues, including collagenases. We hypothesized that purified bacterial collagenase would initiate nociceptive cascades in the joint by degrading the capsular ligament's matrix and activating innervating pain fibers. Intra-articular collagenase in the rat facet joint was investigated for its effects on behavioral sensitivity, joint degeneration, and nociceptive pathways in the peripheral and central nervous systems. In parallel, a co-culture collagen gel model of the ligament was used to evaluate effects of collagenase on microscale changes to the collagen fibers and embedded neurons. Collagenase induced sensitivity within one day, lasting for 3 weeks (p < 0.001) but did not alter ligament structure, cartilage health, or chondrocyte homeostasis. Yet, nociceptive mediators were increased in the periphery (substance P, pERK, and MMP-1; p ≤ 0.039) and spinal cord (substance P and MMP-1; p ≤ 0.041). The collagen loss (p = 0.008) induced by exposing co-cultures to collagenase was accompanied by altered neuronal activity (p = 0.002) and elevated neuronal MMP-1 (p < 0.001), suggesting microscale collagen degradation mediates sensitivity in vivo. The induction of sustained sensitivity and nociception without joint damage may explain the clinical disconnect in which symptomatic joint pain patients present without radiographic evidence of joint destruction.

Remote Virtual Spinal Evaluation in the Era of COVID-19.

BACKGROUND: With the COVID-19 pandemic disrupting many facets of our society, physicians and patients have begun using telemedicine as a platform for the delivery of health care. One of the challenges in implementing telemedicine for the spine care provider is completing a comprehensive spinal examination. Currently, there is no standardized methodology to complete a full spinal examination through telemedicine. METHODS: We propose a novel, remote spinal examination methodology that is easily implemented through telemedicine, where the patient is an active participant in the successful completion of his or her examination. This type of examination has been validated in a neurology setting. To facilitate the telemedicine visit, we propose that video instruction be shared with the patient prior to the telemedicine visit to increase the efficacy of the examination. RESULTS: Since the issuance of stay-at-home order across the states, many spine practices around the country have rapidly adopted and increased their telemedicine program to continue provide care for patients during COVID-19 pandemic. At a tertiary academic center in a busy metropolitan area, nearly 700 telemedicine visits were successfully conducted during a 4-week period. There were no remote visits being done prior to the shutdown. CONCLUSIONS: Implementation of our proposed remote spinal examination has the potential to serve as a guideline for the spine care provider to efficiently assess patients with spine disease using telemedicine. Because these are only suggestions, providers should tailor examination to each individual patient's needs. LEVEL OF EVIDENCE: V. CLINICAL RELEVANCE: It is likely that physicians will incorporate telemedicine into health care delivery services even after the COVID-19 pandemic subsides because of telemedicine's efficiency in meeting patient needs. Using the standard maneuvers provided in our study, spine care providers can perform a nearly comprehensive spine examination through telemedicine. Further studies will be needed to validate the reproducibility and reliability of our methodology.

Intra-articular etanercept attenuates pain and hypoxia from TMJ loading in the rat.

Mechanical overloading of the temporomandibular joint (TMJ) and biochemical changes, like inflammation and hypoxia, contribute to cartilage degeneration and pain associated with osteoarthritis (OA). Yet, how overloading contributes to early dysregulation of chondrocytes is not understood, limiting the development of diagnostics and treatments for TMJ OA. Hypoxia-inducible factors (HIF)-1α/2α in chondrocytes were evaluated at Days 8 and 15 in a rat TMJ pain model induced by jaw loading (1 h/day for 7 days) using immunohistochemistry and compared between cases that induce persistent (3.5 N), acute (2 N), or no (0 N) sensitivity. Hypoxia was measured on Day 8 by immunolabeling of the tracer EF5 and 18 F-EF5 PET imaging. To assess the role of tumor necrosis factor (TNF) in painful TMJ loading, intra-articular etanercept was given before loading. Orofacial sensitivity was evaluated during and after loading. Facial grimace, TNF-α, HIF-2α, and hypoxia levels in the TMJ were measured after loading. HIF-2α was elevated (P = .03) after 3.5 N loading at Day 8, but HIF-1α was unchanged. EF5 uptake increased on Day 8 in the 3.5 N group (P < .048) by tissue assay and 18 F-EF5 PET. At Day 8, both HIF-2α (P = .01) and EF5 uptake (P = .005) were correlated with loading magnitude. Etanercept attenuated sensitivity (P < .01) and the facial grimace on Day 7 (P = .01). It also reduced (P < .01) HIF-2α and EF5 uptake on Day 8; but TNF-α levels were not different from controls at that time. Findings suggest that TMJ loading that induces persistent sensitivity upregulates the catabolic factor HIF-2α and reduces oxygen levels in the cartilage, which may be TNF-driven.

Email as an Encumbrance to Physician-patient Communication.

Physician-patient interaction through email poses several concerns regarding the security, efficiency, and misinterpretation of critical information. Incoming emails received by a single university-based physician in 2013 were analyzed in order to determine whether a general non-patient specific email is appropriate for patient use. Emails received were divided into seven categories: Informational, Academic, Advertisement, Organization/Department/ University, Mission Critical, Personal, and Patient. A total of 9,102 emails were received and read by the physician, with an average of 25 emails per day, out of which 823 (9%) emails were directly sent by patients. The total time spent reading emails was five days, seven hours, and 24 minutes. General email is not an effective means of streamlining physician-patient communication. Non-essential emails, which represent a majority of incoming messages, decrease the productivity of physicians and prevent them from responding to urgent messages in a timely manner. Additionally, this creates the chance for critical patient information getting lost with the volume of received emails. This could be detrimental to patient care and satisfaction. Recently, an online portal was instated to provide a method of secure communication, and less than five patient emails were received in the physician's personal email since then.

Grading facial expression is a sensitive means to detect grimace differences in orofacial pain in a rat model.

Although pre-clinical models of pain are useful for defining relationships between biological mechanisms and pain, common methods testing peripheral sensitivity do not translate to the human pain experience. Facial grimace scales evaluate affective pain levels in rodent models by capturing and scoring spontaneous facial expression. But, the Rat Grimace Scale (RGS) has not assessed the common disorder of temporomandibular joint (TMJ) pain. A rat model of TMJ pain induced by jaw loading (1 hr/day for 7 days) was used to investigate the time course of RGS scores and compare them between different loading magnitudes with distinct peripheral sensitivity profiles (0N-no sensitivity, 2N-acute sensitivity, 3.5N-persistent sensitivity). In the 3.5N group, RGS is elevated over baseline during the loading period and one day after loading and is correlated with peripheral sensitivity (ρ = -0.48, p = 0.002). However, RGS is not elevated later when that group exhibits peripheral sensitivity and moderate TMJ condylar cartilage degeneration. Acutely, RGS is elevated in the 3.5N loading group over the other loading groups (p < 0.001). These findings suggest that RGS is an effective tool for detecting spontaneous TMJ pain and that spontaneous pain is detectable in rats that develop persistent TMJ sensitivity, but not in rats with acute resolving sensitivity.

A Prospective Detailed Time Analysis Study of 18 Patients Undergoing Elective Single-Level Open Lumbar Microdiscectomy Spinal Surgery Compared with Centers for Medicare and Medicaid Services Reimbursement Guidelines.

BACKGROUND: Single-level open lumbar microdiscectomy surgery is one of the most straightforward and effective spinal surgeries performed by spinal surgeons today to treat disk herniation. Although a common operation, little in the literature is reported on the exact overall time, cost, and effort associated with the performance of this surgery. The consistency of this operation across institutions and disciplines makes it a good starting point to accurately track the total time and effort of all phases of the surgical intervention. METHODS: Eighteen patients undergoing elective single-level open lumbar microdiscectomy surgery were prospectively enrolled in this study. The time spent interacting with each patient by every member of the surgical team was tracked and recorded along will every phone call and e-mail. All perioperative times associated with the surgery were tracked and analyzed. Each patient was followed from their first interaction through surgery and for the first 3 months postoperatively. RESULTS: The advanced practice providers spent the most time with the patient both pre- and postoperatively followed by the surgeon and resident. A total of 2.98 hours was spent with the patient preoperatively in clinic and 1.69 hours postoperatively. The total time commitment of an institution treating this condition was 12.56 hours. CONCLUSIONS: Comparing our results with the Centers for Medicare and Medicaid Services data, a significant discrepancy and underestimation was observed. As such, we hope our results enable health care providers to more accurately allocate resources for the provision of high-quality medical care to patients with this increasingly common condition.

Radial Head Subluxation Among Young Children in the United States Associated With Consumer Products and Recreational Activities.

This study investigated the epidemiology of children treated in US emergency departments for radial head subluxation (RHS) associated with consumer products and recreational activities using data from the National Electronic Injury Surveillance System. An estimated 430 766 (95% confidence interval: 341 194-520 339) children ≤5 years of age were treated for RHS in US emergency departments from 1990 to 2011. The mean patient age was 2.1 years, and 56.5% of patients were girls. The most common mechanism of injury was a fall (43.2%), followed by arm pull (39.4%). The annual rate of RHS increased significantly by 190.1% during the 22-year study period. This is the largest study of RHS to date and the first to use a nationally representative sample to investigate secular trends and mechanisms of injury for RHS associated with consumer products and recreational activities. Events associated with consumer products and recreational activities are an important increasing source of RHS.

Vitamin D Deficiency in Slipped Upper Femoral Epiphysis: Time to Physeal Fusion.

BACKGROUND: Slipped upper femoral epiphysis (SUFE) has an incidence of 1 to 7 per 100,000 adolescents in the United Kingdom and its link with obesity is well established. With an increasing number of pediatric orthopaedic patients presenting with vitamin D deficiency, the aim of our study was to establish the prevalence of vitamin D deficiency in SUFE patients presenting to an orthopaedic department in the United Kingdom and whether a low vitamin D level increases the time to proximal femoral physeal fusion after surgical fixation. METHODS: A total of 27 pediatric patients, with a female to male ratio of 17:10 and a mean age of 11.5 years (SD=1.99), range 8 to 16 years, presented with a SUFE and their vitamin D level was assessed during the study period, June 2007 to July 2012 (inclusive). The majority of these patients (85.2%) were assessed as vitamin D deficient, with a serum 25-(OH)D<52 nmol/L. The time taken for >50% physeal fusion on anteroposterior radiography after surgical fixation reported in the literature is 9.6 months, with no reported vitamin D deficiency or insufficiency. RESULTS: In our study, the median time to physeal fusion in the vitamin D-deficient and vitamin D-insufficient patients was 25 months (interquartile range, 17 to 43 mo; mean of 29 mo, SD=16.8). A negative correlation was also observed between vitamin D level and the time taken for physeal fusion after surgical fixation. CONCLUSIONS: We conclude that a high prevalence of vitamin D deficiency has been observed in our SUFE patients. Comparing the time taken for physeal closure of 9.6 months in the literature with vitamin D-deficient patients, this is prolonged. Indeed, a negative correlation has been shown between vitamin D level and time to physeal fusion. This study highlights the need for regular vitamin D status assessment in SUFE patients to allow early implementation of treatment with vitamin D supplementation. The impact of vitamin D screening and supplementation on SUFE outcomes should be investigated further.

Photochemistry of nitrate chemisorbed on various metal oxide surfaces.

Atmospheric aerosols are known to provide an important surface for gas-solid interfaces that can lead to heterogeneous reactions impacting tropospheric chemistry. In this work, α-Fe2O3, TiO2, γ-Al2O3, SiO2 and ZnO, common components of atmospheric aerosols, served as models to investigate the gas-solid interface of nitric acid with aerosols in the presence of simulated solar radiation. Adsorbed nitrate and gaseous products can be continuously monitored with infrared spectroscopy (IR). Kinetic studies of adsorbed species were carried out using attenuated total reflectance infrared spectroscopy (ATR-FTIR). Ex situ simultaneous infrared spectroscopy of gas-phase products using a 2 m long path cell allowed the detection of gaseous products at early stages of the heterogeneous photochemical reaction. In addition, photoactive gaseous products, such as HONO, were detected as gas analysis was carried out outside the region of irradiation. All reactions were found to be first order with respect to adsorbed nitric acid and yielded gas-phase products such as NO, NO2, N2O4, N2O, and HONO. While the correlation between semiconductor properties of the metal oxide and the heterogeneous photochemical rate constant (j) is not direct, the semiconductor properties were found to play a role in the formation of relatively high proportions of greenhouse gas nitrous oxide (N2O).

Isotope trophic-step fractionation: a dynamic equilibrium model.

Trophic position is a fundamental feature of food-web structure, knowledge of which is being improved by stable isotope approaches which assume a constant enrichment in heavier isotopes in consumers relative to their diet. We argue that the typical enrichment reflects a dynamic equilibrium between fractionation vectors associated with assimilation and excretion. We develop a linear model to characterize the relationship between the equilibrium isotopic signature and the feeding rate influenced by isotopic discrimination during assimilation and excretion. We present new data for both diet switching and starvation experiments using a marine worm Nereis virens and use this, and previously published data for a fish, bird and mammal to calculate controlling parameters from observations of the isotopic signature following diet-switching and the onset of starvation. We show that the observed variance in isotopic signatures at each trophic step carries substantially more information than has been used hitherto and is influenced by feeding rate in addition to the isotopic signature of the food source. Using the linear model as a tool we predict that parasitic organisms may be depleted relative to the tissues of their host.
