Harmful female footwear: A public health perspective.

Footwear fashion is an instance of a socially formed attitude affecting somatic population health. High-heeled, particularly pointy-toed shoes are posed to structurally distort and overload feet leading to musculoskeletal sequelae. Here we compiled multilanguage website images presenting female footwear produced by the top manufacturers to assess the advertising effects on the prevailing height of heels worn by women. The method was based on the analysis of websites using the command "woman shoes" in scores of languages of the Internet Google browser. We then compared the results of the internet search with those of a live street surveillance of the footwear worn by 100 adult women in the downtown Warsaw metropolis in Poland. We found that stiletto heels with pointed shoe tips significantly predominated in images representing the countries belonging to the Western cultural sphere compared to less affluent world areas where low or flat heels prevailed. However, we noted a gradual departure from the fashion of high heels over the last decade, confirmed by live street surveillance, liable to reflect changes in the website presentations of top shoe manufacturers consistent with increasing awareness of potential harm by high heels. Yet the female aptitude for wearing more physiologic shoe models appears to exceed that resulting from marketing campaigns. Doing away with high-heeled pointy-toed shoes requires intensification of pro-health preventive measures in the field of public health.

Minocycline prevents hypoxia-induced seizures.

Severe hypoxia induces seizures, which reduces ventilation and worsens the ictal state. It is a health threat to patients, particularly those with underlying hypoxic respiratory pathologies, which may be conducive to a sudden unexpected death in epilepsy (SUDEP). Recent studies provide evidence that brain microglia are involved with both respiratory and ictal processes. Here, we investigated the hypothesis that microglia could interact with hypoxia-induced seizures. To this end, we recorded electroencephalogram (EEG) and acute ventilatory responses to hypoxia (5% O2 in N2) in conscious, spontaneously breathing adult mice. We compared control vehicle pre-treated animals with those pre-treated with minocycline, an inhibitory modulator of microglial activation. First, we histologically confirmed that hypoxia activates microglia and that pre-treatment with minocycline blocks hypoxia-induced microglial activation. Then, we analyzed the effects of minocycline pre-treatment on ventilatory responses to hypoxia by plethysmography. Minocycline alone failed to affect respiratory variables in room air or the initial respiratory augmentation in hypoxia. The comparative results showed that hypoxia caused seizures, which were accompanied by the late phase ventilatory suppression in all but one minocycline pre-treated mouse. Compared to the vehicle pre-treated, the minocycline pre-treated mice showed a delayed occurrence of seizures. Further, minocycline pre-treated mice tended to resist post-ictal respiratory arrest. These results suggest that microglia are conducive to seizure activity in severe hypoxia. Thus, inhibition of microglial activation may help suppress or prevent hypoxia-induced ictal episodes.

Aging and the carotid body: A scoping review.

The carotid body (CB) is a neuroepithelial tissue consisting of O2-sensitive glomus cells that constantly scan the arterial blood for O2 and generate a discharge as an inverse function of O2 content. Aging is a cumulative result of decreased O2 supply paralleled by a decreased O2 tissue demand and oxidative damage to cells derived from aerobic metabolism. Here we studied how CB affects the aging process. This is a study of CB ultrastructural morphometry and immunohistochemical expression of proteins underlying CB responsiveness. The study was based on human CBs obtained from cadavers of people who died due to traumatic events in young and old age. The study was supplemented by investigations of CBs obtained from young and old rats subjected to chronic normoxic and hypoxic conditions. We found changes in the old normoxic CBs akin to the effects of chronic hypoxia such as enhanced extracellular matrix, reduced synaptic contacts between glomus cells, fewer glomus cells, secretory vesicles, and mitochondria. These changes were accompanied by enhanced expressions of hypoxia-inducible factor one-alpha (HIF-1α), vascular endothelial growth factor (VEGF), and nitric oxide synthase (NOS2). We conclude that hypoxia and aging share a common background consisting of deficient O2 tissue supply, mitochondrial dysfunction, and a limited ability to deal with increased cellular oxidative stress. Aging leads to adaptative reductions in CB responsiveness to hypoxia shifting the chemosensory setpoint upward. We submit that the attenuated CB sensitivity at old age may be tantamount to "physiological denervation" leading to a gradual loss of the chemosensing role in the prevention of tissue hypoxia by increasing lung ventilation.

Surgical safety checklist: an element of work organization in the operating theater / Lista de verificação de segurança cirúrgica: um elemento de organização do trabalho no bloco cirúrgico

Objectives: the surgical safety checklist (SSC) is a document that is intended to increase patient safety in the operating theater by eliminating avoidable errors. The original document has been published in English by the WHO which recommends its obligatory use. The document's name is often distorted when translated into European languages, for instance into the "surgical control list". This article aims to assess the consequences of the distortion of the originally intended meaning for the completion of SSC in the operating theater. Methods: we compared the exactness of the meaning of translation in 29 European languages based on Google translator. Particular attention was paid to the presence of essential words such as "checklist" and "safety" in the translation. Results: we found that in 15 out of the 29 languages, the translation of these two words was incorrect, particularly in Slavic languages. The most often mistranslation was the "control card" or "control list", which was a misnomer. Conclusions: the translation of the SSC name into native languages is inadequate in about one-half of the cases, which may jeopardize its proper use by team members of the operating theater, and thus the patient perioperative safety.

Objetivo: a lista de verificação de segurança cirúrgica (SSC) é um documento que visa aumentar a segurança do paciente no centro cirúrgico, eliminando possíveis erros. O documento original foi publicado em inglês pela OMS que recomenda seu uso obrigatório. O nome do documento é frequentemente distorcido quando traduzido para idiomas europeus, por exemplo, na "lista de controle cirúrgico". Este artigo visa avaliar as consequências da distorção do significado originalmente pretendido para a realização do SSC na sala de cirurgia. Métodos: para isso, comparamos a exatidão do significado da tradução em 29 idiomas europeus com base no tradutor do Google. Atenção especial foi dada para a presença de palavras essenciais como "lista de verificação" e "segurança" na tradução. Resultados: descobrimos que em 15 dos 29 idiomas, a tradução dessas duas palavras estava incorreta, principalmente em idiomas eslavos. A tradução incorreta mais frequente era o "cartão de controle" ou "lista de controle", o que era um equívoco. Conclusão: a tradução do nome do SSC para as línguas nativas é inadequada em cerca de metade dos casos, o que pode comprometer seu uso adequado pelos membros da equipe de centro cirúrgico e, portanto, a segurança perioperatória do paciente.

Role of microglia in blood pressure and respiratory responses to acute hypoxic exposure in rats.

Microglia modulate cardiorespiratory activities during chronic hypoxia. It has not been clarified whether microglia are involved in the cardiorespiratory responses to acute hypoxia. Here we investigated this issue by comparing cardiorespiratory responses to two levels of acute hypoxia (13% O2 for 4 min and 7% O2 for 5 min) in conscious unrestrained rats before and after systemic injection of minocycline (MINO), an inhibitor of microglia activation. MINO increased blood pressure but not lung ventilation in the control normoxic condition. Acute hypoxia stimulated cardiorespiratory responses in MINO-untreated rats. MINO failed to significantly affect the magnitude of hypoxia-induced blood pressure elevation. In contrast, MINO tended to suppress the ventilatory responses to hypoxia. We conclude that microglia differentially affect cardiorespiratory regulation depending on the level of blood oxygenation. Microglia suppressively contribute to blood pressure regulation in normoxia but help maintain ventilatory augmentation in hypoxia, which underscores the dichotomy of central regulatory pathways for both systems.

Medical Records: A Historical Narrative.

The history of medical records is thousand-year-long, with earlier roots in ancient civilizations. Until the 19th century, medical records mainly served educational purposes, later assuming other roles such as in insurance or legal procedures. This article comprehensively describes and reviews the development of medical records from ancient to modern times in Europe and North America, reflecting alterations and adaptations compliant with the mental and technological capabilities of a given period. We searched PubMed and Google Scholar databases to collect pertinent articles. English articles or those having English abstracts were considered. The search terms included "Medical Records," "Health Records," "History of Medicine," and "eHealth" and covered the last hundred years. References were also picked out from the identified articles. Overall, 600 articles were identified, 158 of which were judged thematically relevant. The general conclusion is that medical records undergo a revolutionary change from paper-based to electronic format, which reflects the development of eHealth systems. The migration process to eHealth records involves the use of artificial intelligence (AI) algorithms that streamline medical services by using faster and simpler working methods. AI benefits both patients and providers as it improves patient management and communication among medical centers, spares resources, identifies contamination or infections, and limits health costs. These advantages have become pointedly apparent during the recent COVID-19 scourge.

Expression of p11 and TASK1 Channels in Rat Carotid Body Glomus Cells Subjected to Chronic Intermittent Hypoxia.

Chronic intermittent hypoxia (CIH) has been used as a model to mimic nocturnal apnea, which is associated with hypertension. One of the mechanisms for hypertension in patients with nocturnal apnea is an enhancement of the plasma membrane response to acute hypoxia in carotid body glomus cells. Hypoxia is known to induce depolarization via inhibiting TWIK-related acid-sensitive K+ (TASK) channels, one type of leak K+ channels, in glomus cells. The present experiment was undertaken to immunocytochemically investigate the effects of CIH on the expression and intracellular localization of TASK1 channels and p11 that critically affect the trafficking of TASK1 to the cell surface. The expression levels of TASK1 proteins and p11 and their intracellular localization in rat carotid body glomus cells were not noticeably affected by CIH, suggesting that the enhanced membrane response to acute hypoxia is not due to an increase in surface TASK channels.

Dual orexin receptor blocker suvorexant attenuates hypercapnic ventilatory augmentation in mice.

Suvorexant (Belsomra(R)), a dual orexin receptor antagonist widely used in the treatment of insomnia, inhibits the arousal system in the brain. However, the drug's ventilatory effects have not been fully explored. This study aims to investigate the expression of orexin receptors in respiratory neurons and the effects of suvorexant on ventilation. Immunohistology of brainstem orexin receptor OX2R expression was performed in adult mice (n = 4) in (1) rostral ventral respiratory group (rVRG) neurons projecting to the phrenic nucleus (PhN) retrogradely labeled by Fluoro-Gold (FG) tracer, (2) neurons immunoreactive for paired like homeobox 2b (Phox2b) in the parafacial respiratory group/retrotrapezoid nucleus (pFRG/RTN), and (3) neurons immunoreactive for neurokinin 1 receptor (NK1R) and somatostatin (SST) in the preBötzinger complex (preBötC). Additionally, we measured in vivo ventilatory responses to hyperoxic hypercapnia (5% CO2) and hypoxia (10% O2) before and after suvorexant pretreatment (10 and cumulative 100 mg/kg) in unrestrained mice (n = 10) in a body plethysmograph. We found the OX2R immunoreactive materials in pFRG/RTN Phox2b and preBötC NK1R/SST immunoreactive neurons but not in FG-labeled rVRG neurons, which suggests the involvement of orexin in respiratory control. Further, suvorexant expressly suppressed the hypercapnic ventilatory augmentation, otherwise unaffecting ventilation. Central orexin is involved in shaping the hypercapnic ventilatory chemosensitivity. Suppression of hypercapnic ventilatory augmentation by the orexin receptor antagonist suvorexant calls for caution in its use in pathologies that may progress to hypercapnic respiratory failure, or sleep-disordered breathing. Clinical trials are required to explore the role of targeted pharmacological inhibition of orexin in ventilatory pathologies.

In Silico Finite Element Modeling of Stress Distribution in Osteosynthesis after Pertrochanteric Fractures.

A stabilization method of pertrochanteric femur fractures is a contentious issue. Here, we assess the feasibility of rapid in silico 2D finite element modeling (FEM) to predict the distribution of stresses arising during the two most often used stabilization methods: gamma nail fixation (GNF) and dynamic hip screw (DHS). The modeling was based on standard pre-surgery radiographs of hip joints of 15 patients with pertrochanteric fractures of type A1, A2, and A3 according to the AO/OTA classification. The FEM showed that the stresses were similar for both GNF and DHS, with the medians ranging between 53-60 MPa and consistently lower for A1 than A3 fractures. Stresses also appeared in the fixation materials being about two-fold higher for GNF. Given similar bone stresses caused by both GNF and DHS but shorter surgery time, less extensive dissection, and faster patient mobilization, we submit that the GNF stabilization appears to be the most optimal system for pertrochanteric fractures. In silico FEM appears a viable perioperative method that helps predict the distribution of compressive stresses after osteosynthesis of pertrochanteric fractures. The promptness of modeling fits well into the rigid time framework of hip fracture surgery and may help optimize the fixation procedure for the best outcome. The study extends the use of FEM in complex orthopedic management. However, further datasets are required to firmly position the FEM in the treatment of pertrochanteric fractures.

Perception of Well-Being and Quality of Life in Obese Patients After Bariatric Surgery.

Bariatric surgery is the treatment of choice for effective weight reduction in patients with morbid obesity. The influence of the surgery, mostly consisting of laparoscopic sleeve gastrectomy, on mental health is less clear. This study aims to define the influence of bariatric surgery on the perception of well-being and the general quality of life in obese patients. This is a study in which 52 obese patients, 90% of whom are women, were surveyed for the long-term persistence of weight reduction, physical activity, mood, perception of self-confidence, self-worth, and other psycho-socio-emotional factors relating to the general quality of life before and after bariatric surgery. We confirmed persisting effectiveness of surgery for weight reduction. Further, we found that weight reduction was accompanied by enhanced physical activity and amelioration of obesity-related somatic and psycho-emotional maladies. Notably, the perception of self-confidence and self-esteem distinctly improved, resulting in better social interactions and communications. We conclude that psychological improvements resulting from bariatric surgery make the feeling of well-being and general quality of life better, which is liable to drive positive health outcomes.

Quantum Medicine: A Role of Extremely Low-Frequency Magnetic Fields in the Management of Chronic Pain.

Extremely low-frequency electromagnetic field (ELF-MF) therapy is a promising treatment for chronic pain, given its ability to interact with body homeostasis using water-mediated transmission mechanisms typical of quantum medicine. The present study aims to assess the effects of ELF-MF therapy on chronic pain in 49 patients suffering from various musculoskeletal disorders. The therapy was applied through a Quec Phisis setup generating the electromagnetic field as the ion cyclotronic resonance. Patients underwent eight therapy sessions of 45 min each performed every other day. The bioimpedance assessment was based on the comparison of the height-adjusted body resistance (R/h) and reactance (Xc/h) measured during the first and last sessions of eight-session treatment. Pain perception was quantified using the standard visual-analog scale. We found significant increases in both R/h and Xc/h parameters of body bioimpedance after electromagnetic therapy corresponding with reductions in pain perception. We conclude that the ELF-MF therapy can restore the body's state of health and thus seems a valid therapeutic approach for the treatment of musculoskeletal-derived pain.

Artificial Intelligence and Precision Medicine: A Perspective.

This article aims to present how the advanced solutions of artificial intelligence and precision medicine work together to refine medical management. Multi-omics seems the most suitable approach for biological analysis of data on precision medicine and artificial intelligence. We searched PubMed and Google Scholar databases to collect pertinent articles appearing up to 5 March 2021. Genetics, oncology, radiology, and the recent coronavirus disease (COVID-19) pandemic were chosen as representative fields addressing the cross-compliance of artificial intelligence (AI) and precision medicine based on the highest number of articles, topicality, and interconnectedness of the issue. Overall, we identified and perused 1572 articles. AI is a breakthrough that takes part in shaping the Fourth Industrial Revolution in medicine and health care, changing the long-time accepted diagnostic and treatment regimens and approaches. AI-based link prediction models may be outstandingly helpful in the literature search for drug repurposing or finding new therapeutical modalities in rapidly erupting wide-scale diseases such as the recent COVID-19.

Compliance with the Surgery Safety Checklist: An Update on the Status.

WHO has recommended the implementation of the Surgery Safety Checklist (SSC) to reign in often simple logistic errors that lead to numerous complications, some of them being fatal, in the perioperative period. This study aims to discuss doubts presented in the medical literature concerning the effectiveness of SSC in the currently existing form. The article is based on the literature search performed in PubMed using the command phrase "Surgery Safety Checklist". The search yielded 1,476 articles up to March 2021. Out of this group, we selected 811 articles for further detailed analysis. The selection was based on the meritorious SSC-related topicality and scrutinized content of the articles. Out of these articles, we identified 59 studies that specifically raised the issue of the effectiveness of SSC use in its current form, which we discussed herein in detail. The review distinctly indicates that the SSC reduces perioperative complications including fatalities. However, there are issues reported with the itemized content of the checklist that hardly correspond to the diverseness of patients' conditions and operating room settings. Further, it is unclear if a reduction in the complications stems from the use of SSC or the algorithms for performing procedures it contains. The consensus arises that SSC should be periodically updated so that it would catch up with the advances in medical knowledge and the emerging technologies, which would safeguard the SSC from becoming just another paperwork nuisance for the operating room staff.

Activation of Astrocytes in the Persistence of Post-hypoxic Respiratory Augmentation.

Acute hypoxia increases ventilation. After cessation of hypoxia loading, ventilation decreases but remains above the pre-exposure baseline level for a time. However, the mechanism of this post-hypoxic persistent respiratory augmentation (PHRA), which is a short-term potentiation of breathing, has not been elucidated. We aimed to test the hypothesis that astrocytes are involved in PHRA. To this end, we investigated hypoxic ventilatory responses by whole-body plethysmography in unanesthetized adult mice. The animals breathed room air, hypoxic gas mixture (7% O2, 93% N2) for 2min, and again room air for 10min before and after i.p. administration of low (100mg/kg) and high (300mg/kg) doses of arundic acid (AA), an astrocyte inhibitor. AA suppressed PHRA, with the high dose decreasing ventilation below the pre-hypoxic level. Further, we investigated the role of the astrocytic TRPA1 channel, a putative ventilatory hypoxia sensor, in PHRA using astrocyte-specific Trpa1 knockout (asTrpa1 -/-) and floxed Trpa1 (Trpa1 f/f) mice. In both Trpa1 f/f and asTrpa1 -/- mice, PHRA was noticeable, indicating that the astrocyte TRPA1 channel was not directly involved in PHRA. Taken together, these results indicate that astrocytes mediate the PHRA by mechanisms other than TRPA1 channels that are engaged in hypoxia sensing.

Volatile organic compounds (VOCs) in exhaled breath as a marker of hypoxia in multiple chemical sensitivity.

In the history of diagnostics, breath analysis was one of the first method used until the breakthrough of biochemical testing technology. Today, breath analysis has made a comeback with the development of gas analyzers and e-noses, demonstrating its power in its applicability for diagnosing a wide range of diseases. The physical basis of multiple chemical sensitivity (MCS), an emerging environmental disease, is difficult to understand because it is based on the scenario of chronic hypoxia, with a complex of chemical compounds that trigger the syndrome and result in multiple symptoms. The aim of this study was to investigate MCS by analyzing exhaled volatile organic compounds (VOCs). The volatile, metabolic picture could be a putative gold standard for understanding and diagnosing the disease. The study was based on recording in resting condition using the noninvasive passive e-nose contactless breath test, the Olfactory Real-Time Volatile Organic Compounds (ORT-VOC) test in MCS, and control samples. The VOCs profile distinguished between disease and health. It also distinguished the gender-related volatile profile with significant robustness. The results trace a putative compensatory physiological pathway elicited by increased lactate, leading to acidosis, and hyperventilation, resulting in the production of specific VOCs. We conclude that breath testing is a valuable tool to investigate the hypoxia-related VOC profile, facilitating MCS diagnosis.

Causes and Effects of Introducing Surgery Safety Checklist: A Review.

The medical treatment process, particularly surgery, is inescapably bound to potential complications or undesirable adverse events. This narrative review aims to present the causes and effects of the introduction of the WHO Surgery Safety Checklist (SSC), the use of which is expected to reduce the number of perioperative errors, complications, and mortality. To achieve this objective, we performed a bibliometric analysis of medical citations indexed in the PubMed database using the SSC subject heading. Findings revealed a total of 1441 articles meeting inclusion status, with 1171 published during the last decade. After the screening of titles and abstracts, the members of the research team selected 75 articles, deemed most relevant for inclusion in the review, which were then thoroughly analyzed. All in all, the findings were that the use of SSC appreciably reduced the number of simple logistic errors in the perioperative period decreasing the frequency of resulting complications and mortality.

Artificial Intelligence in the Healthcare System: An Overview.

This chapter aims to present insights into the influence of artificial intelligence (AI) on medicine, public health, and the economy. PubMed and Google Scholar databases were used for the identification and collection of articles with search commands of "artificial intelligence" AND "public health" and "artificial intelligence" AND "medicine". A total of 273 articles specifically handling the issue of artificial intelligence, dating ten years back, in three major medical journals: Science, The Lancet, and The New England Journal of Medicine, were analyzed. Computational power gets stronger by the day, giving us new solutions and possibilities. Current medicine problems like personalized medicine, storage of data, and documentation overload will likely be replaced by AI shortly. The application of AI may also bring substantial benefits to other areas of medicine like the diagnostic and therapeutic processes. The development and spread of AI are inescapable as it lowers healthcare and administrative costs, improves medical efficiency, and predicts and prevents major disease complications. The use of AI in medicine seems destined to carry the day.

Manual Pressure Release and Low-Grade Electrical Peripheral Receptor Stimulation in Nonspecific Low Back Pain: A Randomized Controlled Trial.

Chronic nonspecific low back pain is a frequent clinical condition affecting the general population and influencing disability level and quality of life. We performed a single-blinded, randomized, and controlled study to compare the effectiveness of manual pressure release (MPR) and electrical neuromodulation (ENM) treatments in the management of chronic low back pain. There were 20 patients with chronic low back pain randomly assigned to 6 treatment sessions with either technique. Both groups were treated for 2 days a week for 3 weeks. Myofascial trigger points (MTrPs) were identified and skin conductance, pressure-pain threshold, postural changes, and the Oswestry Disability Index were assessed before and after each treatment session, along with the protocol-end data compared against the baseline data in each group. We found an outstanding and about equal deactivation of MTrPs from pre- to post-treatment in both groups, reducing disability in patients with chronic low back pain. The study highlights the ENM as a reliable tool for the evaluation of MTrPs, given a high agreement with the MPR. The effect on the neuromuscular condition of treating the "key trigger points" found in this study advances the knowledge of medical rehabilitation.

Overload of Medical Documentation: A Disincentive for Healthcare Professionals.

This review addresses the theories concerning the development and functioning of medical bureaucracy creating an excess of the patient records. An ever-growing number of medical files comply with the typical development of the bureaucratic management of an entrepreneurial organization, an essential feature of which is the life cycle of documentation. When the life cycle ends, an update is created with a multiplication of forms and items to be filled out, resembling that of what happens with the outdated computer program. Yet medical records should have a logical and well-functioning structure using the language of computer science in the form of a cascade or evolutionary model. Further, we believe that mass computerization, in contradistinction to the primary predestination purpose, increases the number of time-consuming medical records, with the evidence that it enhances the occupational burnout among physicians. Clear and concise medical documentation is necessary to handle economic and legal issues in medicine. However, the creation of medical records sits at the crux between a health-conscious provision of the best evidence-driven treatment and the continuum of care and a potential health detriment caused by taking away the time and care devoted to the patient by healthcare professionals. We submit that the hitherto pattern of creating medical records requires a turnabout to attain the intended reasons and user-friendliness for practical ends.
