Noninvasive central hemodynamic monitoring in the primary care setting: improving prevention and management of cardiovascular diseases.

Background: Although cardiovascular disease (CVD) has markedly declined since the early 1960s due to medical advances and better management, this condition persists as the most critical and preventable cause of death in the US. For that reason, the identification and application of more sensitive, specific, validated, and noninvasive biomarkers of cardiovascular functioning in the primary care setting for the early identification of CVD risk at the subclinical level are warranted. Aim: The goal of the present review is twofold: first, to familiarize the primary care practitioner with noninvasive aortic hemodynamic parameters, including how these could be integrated into primary care services and patient management, and second, to propose a model for earlier detection of CVD based on the noninvasive hemodynamic parameters in the primary care setting. Relevance for Patients: Implementation of noninvasive hemodynamic monitoring in a primary care setting could help in the identification of heart disease risk at the early onset thus preventing the need for expensive treatment or death at later stages.

Effective Nasal Disinfection as an Overlooked Strategy in Our Fight against COVID-19.

Although the recent advent of a vaccine and other therapeutic aids in our fight against COVID-19 has brought us a step closer to controlling the pandemic, our fight is far from over. Handwashing, masks, and social distancing practices are considered reasonable measures to control the spread of the disease have been well accepted by government officials and public health officials despite scarce and conflicting scientific evidence. Taking into consideration the aforementioned measures, there is an additional perhaps overlooked practice that warrants our attention-nasal disinfection and hygiene.

The Incidence of Alcohol Use Disorders during the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic has introduced a myriad of challenges to healthcare systems and public health policies across the globe. Individuals with alcohol use disorders are at peaked risk due to mental, socio-demographic, and economic factors leading to hindered mental health service access, misinformation and adherence. METHODS: Keywords including "alcohol use", "death", "hand sanitizer", "overdose" and "COVID-19" were used to obtain 8 media reports for case analysis. A review of 34 manually extracted records were also conducted using PubMed, MEDLINE, Scopus, and the Embase database with no time and language restrictions. RESULTS: A total of 2,517 individuals with alcohol overdose across the United States, India, Canada, and Iran were presented. The majority of cases were male, ages 21-65. Common contributors were linked to socio-economic changes, disruption to mental health services, and physical isolation. CONCLUSION: While original studies are essential to evaluate the etiologies of alcohol use and misuse during pandemics, the dissemination of misinformation must be curbed by directing vulnerable individuals towards accurate information and access to mental health services.

Chlorpheniramine, an Old Drug with New Potential Clinical Applications: A Comprehensive Review of the Literature.

Chlorpheniramine Maleate (CPM), also known as chlorphenamine, is a potent alkylamine first-generation H1 antihistamine that has been around since the 1950s. CPM is a widely popular drug commonly used to treat allergic conditions, given its antihistamine properties. Although mainly used in over-the-counter treatment for cough and colds, various studies discuss a wide range of CPM's clinical uses, such as treating asthma, plasma cell gingivitis, chronic urticaria, depression, among others. This antihistamine is usually taken orally; however, intravenous, intramuscular, and subcutaneous routes have been documented. Intranasal routes have recently been explored, especially due to its antiviral properties against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Accordingly, given CPM's extensive medical and safety profile, the present review explores this versatile drug's current and potential clinical applications. Although it is widely used mainly for treating common colds and aforementioned allergic conditions, it can be concluded that CPM can be considered to be used for other clinical indications. The repurposing of CPM for other clinical indications such as COVID-19 needs to be further explored through more extensive studies.

Robot-Assisted Radical Prostatectomy After Prior Transurethral Resection of Prostate: An Analysis of Perioperative, Functional, Pathologic, and Oncologic Outcomes.

Background: We performed a retrospective comparison of surgical, oncologic, and functional outcomes after robot-assisted radical prostatectomy between patients who have undergone prior transurethral resection of prostate (TURP) to TURP-naive patients. Methods: Past robotic prostatectomy hospital data were scrutinized to form two matched groups of patients: those who have undergone prior TURP and TURP-naive patients. The perioperative and pathologic data along with functional and oncologic outcomes for a period of 3 years were compared between groups. Results: Compared with TURP-naive patients, prior TURP patients experienced longer robot-assisted laparoscopic prostatectomy times (p < 0.001), increased incidence of bladder neck reconstruction (p = 0.03), greater blood loss (p = 0.0001), and lesser nerve sparing (p < 0.01). Complication rates (p = 0.3), positive surgical margin (p = 0.4), extracapsular disease (p = 0.3), or seminal vesicle invasion (p = 0.1) were comparable between groups. Continence (p = 0.5) and potency (p = 0.1) at 1 year were not different between groups. Biochemical recurrence rates were not different at 3 years (p = 0.9). Diabetes slowed recovery of continence in patients with prior TURP compared with TURP-naive patients until 6 months after surgery. Conclusion: Although prior TURP makes subsequent robotic prostatectomy more technically demanding, it can be safely performed by experienced surgeons without compromising long-term functional or oncologic outcomes.

Serial Thoracic Transforaminal Epidural Steroid Injections for Post-herpetic Neuralgia: A Case Report.

The chronic neuropathic pain of post-herpetic neuralgia (PHN) often persists for months or years after the acute herpes zoster (shingles) episode, may be severe and intractable, and can severely impact the overall quality of life. Antivirals, analgesics, and nerve blocks can effectively shorten the course of shingles and may help to prevent PHN. Although vaccination effectively prevents shingles and PHN, current therapies may be ineffective, and pain management can be challenging when PHN occurs. A 78-year-old female with severe PHN pain in the right thoracolumbar spine, right flank, and right lower abdomen showed poor responses to treatment with amitriptyline, gabapentin, and oxycodone/acetaminophen. However, a series of three thoracic transforaminal epidural steroid injections (TFESIs) effectively treated the PHN and achieved near-complete pain resolution. TFESI can be considered an early and first-choice treatment for PHN, but several courses may be required to achieve adequate and prolonged symptom control.

Minimizing transrectal prostate biopsy-related infections; A prospective randomized trial of povidone-iodine intrarectal cleaning versus formalin needle disinfection.

INTRODUCTION: Transrectal prostate biopsies are associated with post biopsy infection and sepsis. We compared the efficacy of povidone-iodine rectal disinfection versus formalin needle disinfection in preventing post biopsy infection among patients undergoing transrectal ultrasound-guided prostate biopsy. METHODS: Patients scheduled to undergo ultrasound-guided transrectal prostate biopsy (n = 621) over 20 months were randomized into 2 groups to receive either povidone-iodine intrarectal disinfection or formalin disinfection of needle after each core. These were compared to assess which methodology better prevented postprocedure infection. Statistical analysis were used to identify independent factors promoting infections. RESULTS: Two hundred and ninety-eight patients from povidone-iodine intrarectal disinfection were compared with 300 from formalin needle disinfection group. Formalin needle disinfection was associated with significantly more infections (P = 0.02). Escherichia coli was the dominant pathogen, with >50% of cases being quinolone resistant. Type of disinfection (P = 0.002), BMI (P = 0.001), chronic prostatitis (P = 0.002), and diabetes mellitus (P = 0.01) were independent predictors of infections. BMI at 28.95 kg/m2 provided the best predictive cut-off point for infections, irrespective of method of disinfection. Area under the curve for all these parameters together was 0.91. CONCLUSIONS: We conclude that along with oral cephalosporin prophylaxis, povidone-iodine intrarectal disinfection is a superior to formalin needle disinfection alone in preventing post biopsy infection. Patients with BMI >28.95 kg/m2 should be considered at a higher risk for infections.

Effectiveness of Mavrilimumab in Viral Infections Including SARS-CoV-2 Infection - A Brief Review.

Hyperinflammation and cytokine storm has been noted as a poor prognostic factor in patients with severe pneumonia related to coronavirus disease 2019 (COVID-19). In COVID-19, pathogenic myeloid cell overactivation is found to be a vital mediator of damage to tissues, hypercoagulability, and the cytokine storm. These cytokines unselectively infiltrate various tissues, such as the lungs and heart, and nervous system. This cytokine storm can hence cause multi-organ dysfunction and life-threatening complications. Mavrilimumab is a monoclonal antibody (mAb) that may be helpful in some cases with COVID-19. During an inflammation, Granulocyte-macrophage colony-stimulating factor (GM-CSF) release is crucial to driving both innate and adaptive immune responses. The GM-CSF immune response is triggered when an antigen attaches to the host cell and induces the signaling pathway. Mavrilimumab antagonizes the action of GM-CSF and decreases the hyperinflammation associated with pneumonia in COVID-19, therefore strengthening the rationale that mavrilimumab when added to the standard protocol of treatment could improve the clinical outcomes in COVID-19 patients, specifically those patients with pneumonia. With this review paper, we aim to demonstrate the inhibitory effect of mavrilimumab on cytokine storms in patients with COVID-19 by reviewing published clinical trials and emphasize the importance of extensive future trials.

The Safety and Efficacy of Anakinra, an Interleukin-1 Antagonist in Severe Cases of COVID-19: A Systematic Review and Meta-Analysis.

This study aims to assess anakinra's safety and efficacy for treating severe coronavirus disease 2019 (COVID-19). Numerous electronic databases were searched and finally 15 studies with a total of 3,530 patients, 757 in the anakinra arm, 1,685 in the control arm were included. The pooled adjusted odds ratio (OR) for mortality in the treatment arm was 0.34 (95% confidence interval [CI], 0.21 - 0.54, I² = 48%), indicating a significant association between anakinra and mortality. A significant association was found regarding mechanical ventilation requirements in anakinra group compared to the control group OR, 0.68 (95% CI, 0.49 - 0.95, I² = 50%). For the safety of anakinra, we evaluated thromboembolism risk and liver transaminases elevation. Thromboembolism risk was OR, 1.59 (95% CI, 0.65 - 3.91, I² = 0%) and elevation in liver transaminases with OR was 1.35 (95% CI, 0.61 - 3.03, I² = 76%). Both were not statistically significant over the control group. Anakinra is beneficial in lowering mortality in COVID-19 patients. However, these non-significant differences in the safety profile between the anakinra and control groups may have been the result of baseline characteristics of the intervention group, and further studies are essential in evaluating anakinra's safety profile.

Variances in BCG protection against COVID-19 mortality: A global assessment.

The BCG vaccine is known to impart nonspecific immunological benefits alongside conferring protection to tuberculosis in endemic regions. It is also known to protect against bladder cancer and other respiratory tract infections. During the coronavirus disease 2019 (COVID-19) pandemic, the BCG vaccine has gained attention due to its role in conferring protective immunity. We demonstrate the potential immunological protective mechanisms that play a role against COVID-19. We conduct a global assessment of the countries that have the highest and lowest mortality rates determined by an a priori methodology. Lastly, we discuss the potential limitations of incorporating BCG vaccines as potential strategies against COVID-19 and provide recommendations regarding their use in ongoing and future epidemics.

Suicidal Behavior and Medication Adherence in Schizophrenic Patients.

Suicide is one of the potential complications in the Schizophrenic patient population. This review article deals with the significance of antipsychotic medication compliance in decreasing suicidal behavior and hospitalizations in Schizophrenic patients. The medication adherence with second-generation antipsychotics (SGA) like clozapine and long-acting injectables (LAIs) like paliperidone is associated with decrease suicidal behavior and all-cause mortality in Schizophrenic patients. Concomitant treatment of depression and substance abuse disorder in this patient population is also associated with decreasing all-cause mortality and hospitalizations. On the other hand, long-term benzodiazepine use is associated with increase mortality in Schizophrenic patients. We also discuss some important physician intervention strategies to improve medication adherence in Schizophrenic patients like motivational interviewing (MI), behavioral tailoring (BT), and psychosocial interventions like cognitive behavior therapy (CBT).

Forgiveness: protecting medical residents from the detrimental relationship between workplace bullying and wellness.

Bullying of medical residents is associated with numerous negative psychological and physiological outcomes. As bullying within this demographic grows, there is increased interest in identifying novel protective factors. Accordingly, this research investigated whether interpersonal forgiveness buffers the relationship between two forms of workplace bullying and indices of well-being. Medical residents (N = 134, 62% males) completed measures assessing person and work-related bullying victimization, dispositional forgiveness, and depressive symptoms and underwent a series of cardiovascular assessments during which cardiovascular reactivity was induced by a 3-min serial subtraction math task. It was hypothesized that the tendency to forgive would be negatively related to bullying victimization and that forgiveness would reduce the association of bullying with psychological distress (i.e. depressive symptoms), cognition errors (i.e. incorrect serial subtraction computations), and exaggerated cardiovascular reactivity and recovery. Findings show that forgiveness reduced the harmful relationship between the two forms of workplace bullying and depressive symptoms, serial subtraction errors, and cardiovascular reactivity and recovery for systolic blood pressure (SBP). Study results suggest that forgiveness may serve as an effective means for reducing the outcomes of bullying for medical residents. Implications for forgiveness interventions are discussed. Lay summary This research demonstrated that forgiveness reduced the harmful relationship between bullying victimization and negative outcomes (i.e. depressive symptoms, subtraction errors, and exaggerated cardiovascular reactivity and recovery for SBP) in medical residents. This study suggests that forgiveness may serve as a protective factor and provide an effective means for reducing the negative association between workplace bullying and negative outcomes.

Potential Role of Xylitol Plus Grapefruit Seed Extract Nasal Spray Solution in COVID-19: Case Series.

The SARS-CoV-2 virus has created an unprecedented impact on healthcare globally. Being a novel virus, several treatments have been explored against COVID-19. During the early stages of the disease, treatment is mainly supportive. While several studies have suggested different treatment modalities, there is still no definitive treatment against COVID-19. Re-purposing already established medications, with excellent safety profiles, is a possible approach for treating the disease in its early stage. Having a mode of transmission as a droplet mode, several studies have supported how the nose can contain the primary route of entry of SARS-CoV-2. Hence, we postulated that re-purposing a commercially available nasal spray containing xylitol and grapefruit seed extract (GSE), namely Xlear Nasal Spray® (Xlear, Inc., American Fork, USA) could be used as an adjunct treatment of COVID-19. With a well-established safety profile, the components of this nasal spray have been studied and have been shown to have potential efficacy against viral pathogens, including coronavirus, and may potentially regulate pathways important in the initial entry of infection, replication, and systemic response to SARS-CoV-2. We present a series of three mild-moderate risks, symptomatic, COVID-19 patients, treated with the intranasal combination, as an adjuvant to their ongoing treatment, with rapid clinical improvement and shorten time to negativization on repeat intranasal swab test via PCR. No safety issues were noted during the course of treatment. Xlear nasal spray, containing xylitol plus GSE, given its established safety profile and compelling clinical results described here, could be a potential adjunct treatment option in mild-moderate COVID-19 cases.

A Pathophysiological Perspective on COVID-19's Lethal Complication: From Viremia to Hypersensitivity Pneumonitis-like Immune Dysregulation.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the coronavirus responsible for our recent coronavirus disease 2019 pandemic, is driving a lung immunopathology that strongly resembles a severe form of hypersensitivity pneumonitis (HP). A review of recent Severe acute respiratory syndrome-related coronavirus (SARS-CoV) and SARS-CoV-2 medical reports, as well as described characteristics of HP, lead us to postulate a theory for SARS-CoV-2 severe disease. We propose that the novel SARS-CoV-2 can act as a trigger and substrate of an HP-like severe immune reaction especially in genetically vulnerable individuals in addition to those with immune senescence and dysregulation. Accordingly, the purpose of our letter is to shift the emphasis of concern surrounding immune activity from viral infection to an HP-like severe immune reaction. We review similarities in disease presentation between infection and allergy, relevant immunopathology, and outline phases of SARS-CoV-2 disease with perspectives on therapy and critical care. Altogether, the favored course is to begin treatments that address the disease at the earliest phase before immune dysregulation leading to uncontrolled pulmonary inflammation.

Retrospective Cohort Analysis from a High-Volume Center of Prognostic Factors Affecting Biochemical Relapse in Patients with Encapsulated, Margin-Negative, Isolated Seminal Vesicle Invasion After Robot-Assisted Laparoscopic Prostatectomy: A Novel Study.

Purpose: Specimen pathology findings collectively impact the long-term outcomes of robot-assisted laparoscopic prostatectomy. Since seminal vesicle invasion (SVI) is an important independent predictor of biochemical recurrence (BCR), this study was designed to evaluate the influence of isolated SVI in the absence of capsular/margin invasion on BCR. Material and Methods: Pathology reports of 2009 robot-assisted laparoscopic prostatectomy specimens were analyzed retrospectively excluding capsular breach and/or margin-positive cases to include 1409 patients in the study. Factors predicting SVI and BCR in this select group of patients were assessed and statistically analyzed. Survival analysis for PSA (prostate-specific antigen) failure probability and binomial regressions for variable predictability were performed. Results: The African American race was associated with SVI (p < 0.05). PSA had a directly proportional correlation with the occurrence of SVI and BCR. SVI was found to be an independent predictor of BCR, leading to higher odds of BCR at 5 years (odds ratio [OR] 8.2, 95% confidence interval [CI] 4.5-14.6, p < 0.0001). When the seminal vesicle was invaded, the specimen Gleason grade group (SGGG; OR 1.9, 95% CI 1.02-3.7, p = 0.04), PSA (OR 1.2, 95% CI 1.01-1.4, p = 0.03), and BMI (body mass index) (OR 1.2, 95% CI 1.04-1.5, p = 0.01) predicted BCR. Seminal vesicle involvement was not found in SGGG 1. Risk stratification of significant predictors of BCR with isolated SVI identified a subgroup with BMI ≤27.9 kg/m2, PSA ≤8.6 ng/mL, and SGGG 2, which had a significantly better prognosis (p = 0.029, log-rank test). Conclusions: Seminal vesicles are infrequently involved with SGGG 1. Select groups of patients with isolated SVI who have low-grade disease with relatively lower PSA and BMI do not have an aggressive biological behavior and are unlikely to have a BCR, thereby circumventing unnecessary adjuvant therapy with its attendant side effects. The BMI significantly predicted PSA failures and should be considered as an additional risk assessment tool.

Human Adaptations to Multiday Saturation on NASA NEEMO.

Human adaptation to extreme environments has been explored for over a century to understand human psychology, integrated physiology, comparative pathologies, and exploratory potential. It has been demonstrated that these environments can provide multiple external stimuli and stressors, which are sufficient to disrupt internal homeostasis and induce adaptation processes. Multiday hyperbaric and/or saturated (HBS) environments represent the most understudied of environmental extremes due to inherent experimental, analytical, technical, temporal, and safety limitations. National Aeronautic Space Agency (NASA) Extreme Environment Mission Operation (NEEMO) is a space-flight analog mission conducted within Florida International University's Aquarius Undersea Research Laboratory (AURL), the only existing operational and habitable undersea saturated environment. To investigate human objective and subjective adaptations to multiday HBS, we evaluated aquanauts living at saturation for 9-10 days via NASA NEEMO 22 and 23, across psychologic, cardiac, respiratory, autonomic, thermic, hemodynamic, sleep, and body composition parameters. We found that aquanauts exposed to saturation over 9-10 days experienced intrapersonal physical and mental burden, sustained good mood and work satisfaction, decreased heart and respiratory rates, increased parasympathetic and reduced sympathetic modulation, lower cerebral blood flow velocity, intact cerebral autoregulation and maintenance of baroreflex functionality, as well as losses in systemic bodyweight and adipose tissue. Together, these findings illustrate novel insights into human adaptation across multiple body systems in response to multiday hyperbaric saturation.

Abbreviated Screening Breast MRI in Women at Higher-than-Average Risk for Breast Cancer with Prior Normal Full Protocol MRI.

OBJECTIVE: To compare the performance of abbreviated screening breast MRI (ABMR) versus full protocol MRI (FPMR) in women at higher-than-average risk for breast cancer with a prior normal FPMR. METHODS: ABMR was performed on higher-than-average-risk women who had a prior normal FPMR. ABMR protocol consisted of short inversion time inversion recovery imaging, precontrast, and two early postcontrast sequences acquired in under 10 minutes. Retrospective review of ABMR examinations performed from July 2016 to July 2018 was compared with a control group who underwent routine screening with FPMR who had a prior normal FPMR performed from July 2014 to June 2016. Screening outcome metrics were calculated and compared, adjusting for differences in patient demographics. RESULTS: The study cohort included 481 ABMR examinations, while the control group included 440 FPMR studies. There was no significant difference in the abnormal interpretation rate (AIR) or cancer detection rate (CDR) for the ABMR versus the FPMR group (AIR 6.0% vs 6.8% respectively, odds ratio (OR) 0.91, 95% confidence interval (CI): 0.53-1.5, P = 0.73; CDR 8.3 vs 11 cancers detected per 1000 examinations respectively, OR 0.73, 95% CI: 0.20-2.7, P = 0.64). The PPV2 and PPV3 for the ABMR group was 19% and 21% versus 16% and 16% for the FPMR group, with no statistical difference. Sensitivity was 100% in each group with no interval cancers. There was no difference in specificity between the ABMR and FPMR groups, 93% versus 94%, respectively (P = 0.73). CONCLUSION: ABMR may be used to screen higher-than-average-risk women with a prior normal FPMR as outcome metrics are equivalent to FPMR.

Electronic Health Record Implementation: A Review of Resources and Tools.

Implementing an electronic health record (EHR) can be a difficult task to take on and planning the process is of utmost importance to minimize errors. Evaluating the selection criteria and implementation plan of an EHR system, intending interoperability, confidentiality, availability, and integrity of the patient health information data, while ensuring timely, accurate, and regulatory compliant generation of reports is a critical task. This article discusses the selection and implementation plan that will primarily consist of assessing existing institutional workflows for each department, and it outlines the necessities and inclinations of the institution to include in the EHR system for the organization to function properly. Resources and tools are included to assist in the selection of the product as well as ideas on how to train staff and evaluate staff readiness. Regulatory requirements are also included for consideration during the initial process. EHR increases the logistic productivity of workflows and offers a safer way to care for patients. To ensure efficiency, there is a series of steps the provider's staff must follow to ensure proper implementation and handling of the EHR system. Before using the implemented EHR, it is recommended to have a testing protocol in place to ensure areas of possible staff confusion are identified and controlled. Using a proper implementation strategy for a new EHR system can facilitate success, minimize delays, and increase health care worker's satisfaction and decrease the chances of usability being compromised.

Self-regulatory biofeedback training: an intervention to reduce school burnout and improve cardiac functioning in college students.

With the detrimental relationship between school burnout and physiological and cognitive functioning now well documented, interventions to ameliorate school burnout symptomology are needed. This study examined the effectiveness of a self-regulatory biofeedback intervention program (Heart Rate Variability Coherence Biofeedback Training [HRVCB]) in contrast to a protocol demonstrated to produce cognitive and physiological improvements (a high intensity interval training protocol [HIIT]) as well as a wait-list control condition at decreasing school burnout in an American collegiate sample (N = 90). Intervention training was conducted over a 4-week span (three sessions per week) with accompanying baseline and post-intervention assessments. In addition to measurements of school burnout and negative affect (depression and anxiety), intervention influences on cognition (via a serial subtraction task) and physiology (hemodynamics, electrocardiography, and a submaximal cardiorespiratory fitness test) were explored. Findings indicate HRVCB training significantly decreased school burnout and increased mathematical performance from pre- to post-intervention measurement. These changes did not occur for HIIT or waitlist participants. Brachial and aortic systolic blood pressure decreased pre to post-intervention for HRVCB but not HIIT or waitlist participants. Cardiovascular fitness (VO2max) improved pre to post-intervention for HIIT but not HRVCB or waitlist participants. Also, both HRVCB and HIIT training participants decreased heart rate from pre to post-intervention but not waitlist participants. Finally, all participants decreased cardiac sympathovagal tone from pre to post-intervention. These findings provide evidence that HRVCB training programs can decrease school burnout as well as improve components associated with cardiac health. Study limitations and directions for future research are discussed.
