ETHNOPHARMACOLOGICAL RELEVANCE
Coptis chinensis Franch. polysaccharide (CCP) and berberine (BBR) are the primary active components of Coptis chinensis Franch. BBR is clinically used for the treatment of intestinal infections and gastroenteritis. CCP was also reported to be effective for the treatment of ulcerative colitis (UC). However, whether CCP combined with BBR shows a synergistic effect on the treatment of UC has not been elucidated yet.
AIM OF THE STUDY
This study aspired to investigate the therapeutic effect and the possible mechanisms of the combination of CCP with BBR on chronic UC.
MATERIALS AND METHODS
By periodic administration of dextran sulfate sodium (DSS) to C57BL/6J mice, chronic UC model mice were induced. CCP (15 mg/kg), BBR (50 mg/kg), and CCP.BBR (a combination of 15 mg/kg CCP and 50 mg/kg BBR) were orally administered to the model mice for 10 days. Changes of body weight, disease activity index, colon length, organ index, histopathological damage, expression of cytokines, and intestinal tight junction proteins were determined to evaluate the therapeutic effects. 16S rDNA sequencing, targeted short-chain fatty acid metabolomics, qPCR, and western blotting were performed to elucidate the potential mechanism.
RESULTS
Both CCP and BBR alleviated UC via improving colon pathological damage, inhibiting the inflammatory response, and regulating the expression of intestinal tight junction proteins. The combination of CCP with BBR showed a more substantial therapeutic effect via increasing the relative abundance of short-chain fatty acids (SCFAs) producing bacteria, thereby increasing the contents of SCFAs in vivo and activating AhR/IL-22 pathway.
CONCLUSION
The combination of CCP and BBR showed a synergistic effect on the therapy of chronic UC and the mechanism was associated with regulating gut microbiota and activating AhR/IL-22 pathway.

The symptoms of acute renal infarction (ARI) caused by atheroemboli are vague, making it rare. Early diagnosis of renal infarction can be made through contrast-enhanced CT of the abdomen. However, diagnosing atheroemboli is more challenging. Kidney biopsy is the most accurate method to determine the cause, but it may not always be available in clinical settings. In cases where a thrombectomy is performed, white substances in thrombus aspiration or the patient's blood can suggest a diagnosis. Intervention is an effective technique, but there is controversy due to a lack of data, particularly in lobular artery infarction. We successfully treated one case using thrombus aspiration, and the specimens suggested atherosclerosis as the cause.

PURPOSE
To understand the contextual and psychosocial factors associated with youth vaping in Colorado, the state with the highest youth vaping rates in 2019, and to propose strategies for prevention interventions.
DESIGN
Focus groups.
SETTING
In-person.
PARTICIPANTS
24 youth aged 11-17, including youth who had vaped (n = 11) and who had never vaped (n = 13).
METHOD
Qualitative responses using a semi-structured focus group guide were analyzed using a matrix approach with a mixed deductive/inductive content analysis.
RESULTS
Analysis revealed the highly social nature of vaping initiation and use; the use of vaping to control negative emotions; and the acquisition of vaping products through retail outlets, friends, family, and other youth who sell a variety of substances and devices to youth. Youth provided insight into how vaping is concealed from parents and teachers, and their attitudes about the health risks and benefits of vaping.
CONCLUSION
When considered with other studies, our findings suggest a universality in the youth vaping experience that is highly social. Interventions should include peer-to-peer messaging with an emphasis on changing social norms and highlighting undesirable outcomes of vaping such as negative reactions by friends and close adults, adverse effects on athletic success and future aspirations, expense, addiction, and punishment. Parent education is also recommended. Rigorous research is needed to test interventions to reverse the growing trend of youth vaping.

Self-stabbing and self-cutting represents an uncommon method of suicide. We present a case of a 30-year-old man who was found dead in the forest. The body was naked and showed multiple cut and stab wounds on different parts of the body (face, neck, chest, abdomen, and extremities). A single-edged kitchen knife was found approximately 20 m from the body. Parts of both ears, the fifth toe of the right foot, and the scrotum were cut off. At the autopsy, two of the severed body parts-the toe and the part of the left ear-were found in the stomach. The cause of death was asphyxiation due to blood aspiration resulting from a cut throat injury. A police investigation uncovered a history of substance abuse and two previous suicidal attempts using a knife. Upon complex analysis of all the evidence, the manner of death was ruled a suicide, which was preceded by actions of major self-mutilation and self-cannibalism, both considered rare behavioral patterns.

Review
BACKGROUND
Routine monitoring of gastric residuals in preterm infants on tube feeds is a common practice in neonatal intensive care units used to guide initiation and advancement of enteral feeding. There is a paucity of consensus on whether to re-feed or discard the aspirated gastric residuals. While re-feeding gastric residuals may aid in digestion and promote gastrointestinal motility and maturation by replacing partially digested milk, gastrointestinal enzymes, hormones, and trophic substances, abnormal residuals may result in vomiting, necrotising enterocolitis, or sepsis.
OBJECTIVES
To assess the efficacy and safety of re-feeding when compared to discarding gastric residuals in preterm infants. SEARCH METHODS: Searches were conducted in February 2022 in Cochrane CENTRAL via CRS, Ovid MEDLINE and Embase, and CINAHL. We also searched clinical trial databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs.
SELECTION CRITERIA
We selected RCTs that compared re-feeding versus discarding gastric residuals in preterm infants.
DATA COLLECTION AND ANALYSIS
Review authors assessed trial eligibility and risk of bias and extracted data, in duplicate. We analysed treatment effects in individual trials and reported the risk ratio (RR) for dichotomous data and the mean difference (MD) for continuous data, with respective 95% confidence intervals (CIs). We used the GRADE approach to assess the certainty of evidence.
MAIN RESULTS
We found one eligible trial that included 72 preterm infants. The trial was unmasked but was otherwise of good methodological quality. Re-feeding gastric residual may have little or no effect on time to regain birth weight (MD 0.40 days, 95% CI -2.89 to 3.69; 59 infants; low-certainty evidence), risk of necrotising enterocolitis stage ≥ 2 or spontaneous intestinal perforation (RR 0.71, 95% CI 0.25 to 2.04; 72 infants; low-certainty evidence), all-cause mortality before hospital discharge (RR 0.50, 95% CI 0.14 to 1.85; 72 infants; low-certainty evidence), time to establish enteral feeds ≥ 120 mL/kg/d (MD -1.30 days, 95% CI -2.93 to 0.33; 59 infants; low-certainty evidence), number of total parenteral nutrition days (MD -0.30 days, 95% CI -2.07 to 1.47; 59 infants; low-certainty evidence), and risk of extrauterine growth restriction at discharge (RR 1.29, 95% CI 0.38 to 4.34; 59 infants; low-certainty evidence). We are uncertain as to the effect of re-feeding gastric residual on number of episodes of feed interruption lasting for ≥ 12 hours (RR 0.80, 95% CI 0.42 to 1.52; 59 infants; very low-certainty evidence).
AUTHORS' CONCLUSIONS
We found only limited data from one small unmasked trial on the efficacy and safety of re-feeding gastric residuals in preterm infants. Low-certainty evidence suggests re-feeding gastric residual may have little or no effect on important clinical outcomes such as necrotising enterocolitis, all-cause mortality before hospital discharge, time to establish enteral feeds, number of total parenteral nutrition days, and in-hospital weight gain. A large RCT is needed to assess the efficacy and safety of re-feeding of gastric residuals in preterm infants with adequate certainty of evidence to inform policy and practice.

In reality, the lines between factitious disorder, functional disorder, and malingering are quite blurred. In factitious disorder and malingering, patients consciously and deliberately create false medical and/or psychiatric symptoms for self-gain, often approaching multiple healthcare facilities to evade detection. Although the factitious disorder is pervasive, and the literature lacks accurate and consistent information, comorbidity with nonepileptic seizure (NES, a component of functional disorder) is quite commonly documented. In our case, the patient feigned multiple symptoms including two seizures and a shoulder dislocation to gain access to opioids. The clinical picture was only significant for alcohol withdrawal, aspiration pneumonia (possibly intubation vs. NES-related), and self-induced shoulder dislocation. Generally, management of these disorders should involve multiple specialties, multiple approaches, and identifying the triggering and comorbid psychological disorders, such as abandonment issues, personality disorders, physical or emotional abuse, anxiety, depression, stress, and substance use. Blindly approaching patients with a factitious disorder or malingering will not lead to any productive outcomes. Perhaps, creating a patient database could help reduce futile efforts while providing patients with the required help. This case report describes the presentation, diagnosis, management, and outcomes related to a patient with NES, engaging the reader to decipher the most appropriate diagnosis.

Review
RATIONALE
Burns are one of the most debilitating injuries in the world and one of the major causes of accidental disability and death among children. Severe burns can result in irreversible brain damage, placing patients at high risk of brain failure and high mortality. Therefore, timely diagnosis and treatment of burn encephalopathy are crucial for improving prognosis. In recent years, extracorporeal membrane oxygenation (ECMO) has been increasingly used to improve the prognosis of patients with burns. Here, we report a case of ECMO treatment in a child with burns and review the relevant literature.
PATIENT CONCERNS
A 7-year-old boy with a modified Baux score of 24 presented with asphyxia, loss of consciousness, refractory hypoxemia, and malignant arrhythmia after smoke inhalation for 1 day. Fiberoptic bronchoscopy revealed a large amount of black carbon-like substances aspirated from the trachea.
DIAGNOSES
Considering that the boy inhaled a large amount of smoke, the clinical manifestation was unclear consciousness, laboratory examination revealed continuous low blood oxygen saturation, and bronchoscopy revealed a large amount of black carbon-like substances in the trachea, thereby leading to the diagnosis of asphyxia, inhalation pneumonia, burn encephalopathy, multiple organ dysfunction syndrome, and malignant arrhythmia. In addition, pulmonary edema and carbon monoxide poisoning are caused by chemical agents, gas fumes, and vapors.
INTERVENTIONS
The boy's blood oxygen saturation and blood circulation remained unstable despite various ventilation methods and medications, thus we decided to use ECMO. After 8 days of ECMO support, the patient was successfully weaned from the machine.
OUTCOMES
Under the application of ECMO, the respiratory and circulatory systems significantly improved. Nevertheless, due to the progressive brain injury caused by burns and the poor prognosis, the parents ceased all treatment and the boy passed away.
LESSONS
This case report demonstrates that brain edema and herniation can arise as phenotypes of burn encephalopathy, which is a challenge to treat in children. Children with confirmed or suspected burn encephalopathy should undergo diagnostic tests completed as soon as possible to confirm the diagnosis. After receiving ECMO treatment, the respiratory and circulatory systems of the burn victims reported significantly improved. Hence, ECMO is a viable alternative for supporting patients with burns.

Voluntary drug intoxication is mainly due to drug overdose or the interaction of several drugs. Coma and its associated complications such as hypoventilation, aspiration pneumopathy, and heart rhythm disorders are the main hallmarks of drug intoxication. Conventional detoxification treatments, including gastric lavage or vomiting, administration of ipecac or activated charcoal (CH), and the use of antidotes, have proven to be inefficient and are generally associated with severe adverse effects. To overcome these limitations, titanate nanotubes (TiNTs) are proposed as an efficient emerging detoxifying agent because of their tubular shape and high adsorption capacity. In the present study, the detoxifying ability of TiNTs was evaluated on paracetamol (PR)-intoxicated rats. Results indicate that the loading ability of PR into TiNTs (70%) was significantly higher than that recorded for CH (38.6%). In simulated intestinal medium, TiNTs showed a controlled drug release of less than 10% after 72 h of incubation. In PR-intoxicated rats, TiNTs treatment resulted in a 64% decrease of PR after 4 h of poisoning 40% for CH. Concomitantly, TiNTs efficiently reduced PR absorption by 90% after 24 h of poisoning, attenuated the elevated levels of biochemical markers (, alanine aminotransferase, aspartate aminotransferase, creatinine, and TNF-α) and mitigated oxidative stress by increasing the activity of superoxide dismutase and reducing the oxidized glutathione/total glutathione ratio, suggesting a histoprotective effect of TiNTs against paracetamol-induced toxicity in rats. In addition to their safety and high stability in the entire gastro-intestinal tract, biodistribution analysis revealed that TiNTs exhibited low intestinal absorption owing to their large cluster size of compact aggregate nanomaterials across the intestinal villi hindering the absorption of paracetamol. Collectively, these data provide a new and promising solution for detoxification. TiNTs are expected to have great potential for the treatment of voluntary and accidental intoxication in emergency care.

The modern era for mental health parity in the US began in 1996, when Congress enacted the Mental Health Parity Act (MHPA), which required equivalence in aggregate lifetime and annual dollar limits for mental health benefits and medical/surgical benefits. Mental health parity generally refers to the equal treatment of mental health conditions and physical health conditions in insurance plans, the substance of which extends far beyond equivalence in the dollar limits of benefits. Mental health parity is a foundational aspiration that has not yet been fulfilled in the US; this article describes details of subsequent legislation that has created new opportunity to finish the work that was started by MHPA, to achieve actual mental health parity, with particular reference to the needs of children.
