Recently, we observed that the specialized proresolving mediator (SPM) entity resolvin D1 activates lipoxin A/formyl peptide receptor 2 (ALX/FPR2), which facilitates cardiac healing and persistent inflammation is a hallmark of impaired cardiac repair in aging. Splenic leukocyte-directed SPMs are essential for the safe clearance of inflammation and cardiac repair after injury; however, the target of SPMs remains undefined in cardiac healing and repair.

Common anorectal conditions include hemorrhoids, perianal pruritus, anal fissures, functional rectal pain, perianal abscess, condyloma, rectal prolapse, and fecal incontinence. Although these are benign conditions, symptoms can be similar to those of cancer, so malignancy should be considered in the differential diagnosis. History and examination, including anoscopy, are usually sufficient for diagnosing these conditions, although additional testing is needed in some situations. The primary treatment for hemorrhoids is fiber supplementation. Patients who do not improve and those with large high-grade hemorrhoids should be referred for surgery. Acutely thrombosed external hemorrhoids should be excised. Perianal pruritus should be treated with hygienic measures, barrier emollients, and low-dose topical corticosteroids. Capsaicin cream and tacrolimus ointment are effective for recalcitrant cases. Treatment of acute anal fissures with pain and bleeding involves adequate fluid and fiber intake. Chronic anal fissures should be treated with topical nitrates or calcium channel blockers, with surgery for patients who do not respond to medical management. Patients with functional rectal pain should be treated with warm baths, fiber supplementation, and biofeedback. Patients with superficial perianal abscesses not involving the sphincter should undergo office-based drainage; patients with more extensive abscesses or possible fistulas should be referred for surgery. Condylomata can be managed with topical medicines, excision, or destruction. Patients with rectal prolapse should be referred for surgical evaluation. Biofeedback is a first-line treatment for fecal incontinence, but antidiarrheal agents are useful if diarrhea is involved, and fiber and laxatives may be used if impaction is present. Colostomy can help improve quality of life for patients with severe fecal incontinence.

Chronic pain is prevalent in adults with cerebral palsy. We aimed to explore associations between chronic pain and somatosensory, motor, cognitive, etiologic, and environmental factors in adults with cerebral palsy. This cross-sectional study enrolled 17 adult participants with cerebral palsy (mean age 31 years; 8 female; Gross Motor Functional Classification Status levels I-V) able to self-report and 10 neurotypical adult volunteers (mean age 34 years; 9 female). Participants reported pain characteristics, demographics, and affective factors. Physical examination included somatosensory and motor evaluation. Between-group comparisons used a ranksum test, and correlation analyses estimated effect size in terms of shared variance (ρ). Individuals with cerebral palsy reported greater pain intensity, neuropathic qualities, and nociceptive qualities than control participants. Higher pain intensity was associated with female gender (ρ = 16%), anxiety/depression symptoms (ρ = 10%), and lower household income (ρ = 19%). It was also associated with better communicative ability (ρ = 21%), spinothalamic (sharp/temperature) sensory abnormalities (ρ = 33%), and a greater degree of prematurity (ρ = 17%). This study highlights similarity of chronic pain associations in people with cerebral palsy with patterns seen in other populations with chronic pain. Spinothalamic sensory abnormalities suggest central pain mechanisms.

To evaluate the effects of analgesia by sacral surface electrical stimulation on lower abdominal pain in women with primary dysmenorrhoea.

Since 2000, over 413,000 US service members (SM) experienced at least one traumatic brain injury (TBI), and 40% of those with in-theater TBIs later screened positive for comorbid psychological health (PH) conditions, including post-traumatic stress disorder (PTSD), depression, and anxiety. Many SMs with these persistent symptoms fail to achieve a recovery that results in a desirable quality of life or return to full duty. Limited information exists though to guide treatment for SMs with a history of mild TBI (mTBI) and comorbid PH conditions. This report presents the methods and outcomes of an interdisciplinary intensive outpatient program (IOP) in the treatment of SMs with combat-related mTBI and PH comorbidities. The IOP combines conventional rehabilitation therapies and integrative medicine techniques with the goal of reducing morbidity in multiple neurological and behavioral health domains and enhancing military readiness. SMs ( = 1,456) with residual symptoms from mTBI and comorbid PH conditions were treated in a 4-week IOP at the National Intrepid Center of Excellence (NICoE) at Walter Reed National Military Medical Center (WRNMMC). The IOP uses an interdisciplinary, holistic, and patient-centric rehabilitative care model. Interdisciplinary teams provide a diagnostic workup of neurological, psychiatric, and existential injuries, and from these assessments, individualized care plans are developed. Treatment response was assessed using the Neurobehavioral Symptom Inventory (NSI), PTSD Checklist-Military Version (PCL-M), Satisfaction With Life Scale (SWLS), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Epworth Sleepiness Scale (ESS), and Headache Impact Test-6 (HIT-6) and administered at admission, discharge, and at 1, 3, and 6 months post-discharge. Following treatment in the IOP, the symptomatic patients had statistically significant and clinically meaningful improvements across all outcome measures. The largest effect size was seen with GAD-7 ( = 0.59), followed by PHQ-8 ( = 0.56), NSI ( = 0.55), PCL-M ( = 0.52), ESS ( = 0.50), SWLS ( = 0.49), and HIT-6 ( = 0.42). In cross-sectional follow ups, the significant improvements were sustained at 1, 3, and 6 months post-discharge. This report demonstrates that an interdisciplinary IOP achieves significant and sustainable symptom recovery in SMs with combat-related mTBI and comorbid PH conditions and supports the further study of this model of care in complex medical conditions.

The novel coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to a global pandemic, and resulted in high case-fatality rate in the elderly. In addition to typical respiratory responses, ~50% of clinical cases include gastrointestinal symptoms such as diarrhea, vomiting, abdominal pain, and persistent fecal shedding of the virus even after its clearance from the pulmonary system. In the present study, we assessed aging-associated gut transcriptomic responses considering the gastrointestinal symptoms contributing to COVID-19 severity. Intestinal expression of SARS-CoV-2 receptors and defense biomarkers decreased with increasing age. Moreover, aging-associated integrated stress responses (ISR) and mTOR-linked cell metabolic stress signals counteracted gut defense biomarkers. However, SARS-CoV-2 receptor expression was positively associated with gut barrier integrity potently via downregulation of the two stress-responsive signals. Gut transcriptome-based mechanistic prediction implicates that high susceptibility to COVID-19 in the elderly with low SARS-CoV-2 receptors is due to aging stress-associated defective gut defense, providing a new avenue for viral entry receptor-independent interventions.

Pineal cysts are common entities, with a reported prevalence between 10 and 54%. Management of pineal cysts has historically been expectant, with surgical treatment of these lesions usually reserved for patients with a symptomatic presentation secondary to mass effect. The appropriate management of pineal cysts in patients presenting with headache in the absence of hydrocephalus – often the most common clinical scenario – has been more ambiguous. Here, we report the results of a comprehensive systematic review of headache outcomes for surgically treated, non-hydrocephalic pineal cyst patients without signs of increased intracranial pressure (ICP).

This study set out to investigate the effect of massage on the Toll-like receptor 4 (TLR4) signalling pathway in the dorsal root ganglia of rats that had undergone spinal nerve ligation (SNL), with the hypothesis that massage could be used as an analgesic. Forty female SD rats were randomly divided into 5 groups: the control group, sham-operated group, model group, sham massage group, and massage group. There were 8 rats in each group. SNL rat models were established in the model group, sham massage group, and massage group. Rats in the sham-operated group underwent surgery to expose the vertebral nerves, but no further procedures were performed. The control group consisted of intact animals. The rats in the massage group underwent massage using a massage simulation machine once a day for 14 d in succession; the hind limbs of the rats in the sham massage group were gently touched with a cloth bag once a day for 14 continuous days. The rats in the control group, the sham-operated group, and the model group did not receive any intervention and were observed for 14 d. Paw withdrawal thermal latency (PWTL) and paw withdrawal mechanical threshold (PWMT) of rats in each group were detected 1 d before modelling and at 1, 3, 7, and 14 d after modelling. Fourteen days after modelling, the expression levels of TLR4, IRAK1, TRAF6, TNF-, and IL-6 were detected in all rats. The PWTL and PWMT of SNL rats were decreased, while these parameters were elevated after massage. SNL rats showed higher levels of TLR4, IRAK1, TRAF6, IL-6, and TNF-, and massage effectively lowered the expression levels of these molecules. Inhibiting activation of the TLR4 signalling pathway, which can reduce the release of inflammatory factors, may be one mechanism by which massage treats neuropathic pain.

Epidural anesthesia minimizes perioperative pain in dogs. It is considered that epidural solution dispersion in cadavers is similar to alive dogs. The objective of the anatomical study was to compare the dispersion of 0.2 mL/kg 0.25% bupivacaine and iohexol via lumbar epidural (L1-L2) under fluoroscopic guidance in 10 thawed cadavers (GC) and 13 female dogs (G0.25) (5-15 kg; body score 4/5). The objective of the clinical study was to evaluate postoperative analgesic consumption and sedation for 6 h after extubation of dogs submitted to ovariohysterectomy when using 0.25% (G0.25; = 10) bupivacaine with the intraoperative use of fentanyl (GF; = 10). Parametric data were compared by the -test and non-parametric data by the Mann Whitney test. Pain and sedation scores were evaluated over time by the Friedman test, followed by the Dunn test. Alive dogs presented greater epidural dispersion (17 ± 3 vertebrae) than thawed cadavers (11 ± 4 vertebrae; = 0.002). All dogs treated with fentanyl and only one dog treated with 0.25% epidural bupivacaine presented pain scores above the cut-off point of the Glasgow Composite Measure Pain Scale Short-Form (GCMPS-SF) and required postoperative rescue analgesia up to 6 h after extubation. The sedation score was higher at all postoperative moments compared to preoperative moments in the G0.25 and GF, except for evaluations performed at 5 and 6 h after extubation in the GF. Greater sedation was observed immediately after extubation in the GF compared to the G0.25, and there was greater sedation in the G0.25 compared to the GF from 3 to 6 h after extubation. The conclusion of the anatomical study was that L1-L2 epidural bupivacaine dispersion is lower in canine thawed cadavers than in alive dogs. Conclusion of the clinical study was that lumbar epidural anesthesia improved postoperative analgesia and produced longer postoperative sedation when compared to fentanyl.

Atypical headaches are uncommon and require special consideration by a primary care physician. We report the case of a 37-year-old male, who presented to the family medicine practice with persistent headaches which subsided postprandial and was later hospitalized for stroke-like symptoms. The lumbar puncture (LP) suggested viral etiology; however, cerebrospinal fluid (CSF) yielded no evidence of a specific virus. The patient computed tomography (CT) was non-diagnostic and magnetic resonance imaging (MRI) confirmed no acute intracranial abnormalities. Electroencephalogram (EEG) showed no definite epileptiform discharges, electrographic seizures, or evidence of non-convulsive status epilepticus. He was started empirically on intravenous (IV) acyclovir 800 mg Q6 for 10 days, followed by another 10 days of oral valacyclovir 500 mg twice a day (BID) antivirals leading to a complete resolution of his symptoms and confirming the diagnosis as viral encephalitis. This case is unique in its presentation due to the postprandial resolution of the patient's headache with no evidence of a specific virus in the CSF. In primary care setting, headaches are often referred routinely to neurologist for further management. However, more insidious causes for a headache, such as viral infections, should not be ruled out; and if the symptoms are acute and severe, an immediate inpatient work-up with empiric treatment for the most probable etiology may be warranted, despite unequivocal exam and laboratory findings.
