Background: Currently, there is conflicting clinimetric data on the patient-rated tennis elbow evaluation (PRTEE) and a paucity of evidence regarding the reliability, validity, and responsiveness of the numeric pain rating scale (NPRS), and tennis elbow function scale (TEFS) in patients with lateral elbow tendinopathy.

Objective: Perform a comprehensive clinimetric analysis of the NPRS, PRTEE, and TEFS in a sample of patients ( = 143) with lateral elbow tendinopathy.

Methods: Establish the reliability, construct validity, responsiveness, meaningful clinically important difference (MCID), and minimal detectable change (MDC) values for the NPRS, PRTEE, and TEFS at the 3-month follow-up.

High-density nerve cuffs have been successfully utilized to restore somatosensation in individuals with lower-limb loss by interfacing directly with the peripheral nervous system. Elicited sensations via these devices have improved various functional outcomes, including standing balance, walking symmetry, and navigating complex terrains. Deploying neural interfaces in the lower limbs of individuals with limb loss presents unique challenges, particularly due to repetitive muscle contractions and the natural range of motion in the knee and hip joints for transtibial and transfemoral amputees, respectively.

Background: The global mpox outbreak which started in May 2022 was caused by a novel clade IIb variant of the mpox virus (MPXV). It differed from the traditional Western and Central Africa disease in transmission patterns and clinical presentation.

Methods: To address the need for detailed clinical and virologic data, we conducted an observational cohort study (MOSAIC) during May 2022-July 2023 in individuals with confirmed MPXV infection enrolled in six European Countries.

The west Africa Ebola disease epidemic (2014-16) marked a historic change of course for patient care during emerging infectious disease outbreaks. The epidemic response was a failure in many ways-a slow, cumbersome, and disjointed effort by a global architecture that was not fit for purpose for a rapidly spreading outbreak. In the most affected countries, health-care workers and other responders felt helpless-dealing with an overwhelming number of patients but with few, if any, tools at their disposal to provide high-quality care.

A key lesson from the west Africa (2014-16) Ebola disease epidemic was that outbreak responses fail when they respond to patients through a narrow clinical lens without considering the broader community and social context of care. Here, in the second of two Series papers on the modern landscape of Ebola disease, we review progress made in the last decade to improve patient-centred care. Although the biosafety imperatives of treating Ebola disease remain, recent advances show how to mitigate these so that patients are cared for in a safe and dignified manner that encourages early treatment-seeking behaviour and provides support after the return of patients to their communities.

High-level isolation units (HLIUs) are facilities strategically outfitted to receive patients with suspected or confirmed high-consequence infectious diseases (HCIDs). Although most HCID outbreaks occur in low- and middle-income countries, global travel and migration and the deployment of healthcare workers to global outbreaks have led to the occurrence of HCIDs in high-income countries that requires the activation of an HLIU. Despite the existence of HLIUs worldwide, there has been little collaboration between units at the international level.

Nipah virus disease is a bat-borne zoonosis with person-to-person transmission, a case-fatality rate of 38-75%, and well recognised potential to cause a pandemic. The first reported outbreak of Nipah virus disease occurred in Malaysia and Singapore in 1998, which has since been followed by multiple outbreaks in Bangladesh and India. To date, no therapeutics or vaccines have been approved to treat Nipah virus disease, and only few such candidates are in development.

Humans become more selective with whom they spend their time, and as a result, the social networks of older humans are smaller than those of younger ones. In non-human animals, processes such as competition and opportunity can result in patterns of declining sociality with age. While there is support for declining sociality with age in mammals, evidence from wild bird populations is lacking.

There is increased recognition for solutions that address the social determinants of health (SDOHs)-the context in which families are raising children. Unfortunately, implementing solutions that address inequities in the SDOHs has proven to be difficult. Many child and family serving systems and communities do not know where to start or do not have the capacity to identify and implement upstream SDOH strategies.

Background: There is an increasing prevalence of durable mechanical circulatory supported patients in both the in-and-out of hospital communities. The scientific literature regarding the approach to patients supported by durable mechanical circulatory devices who suffer acutely impaired perfusion has not been well explored.

Methods: The International Liaison Committee on Resuscitation Advanced, Basic, and Pediatric Life Support Task Forces conducted a scoping review of the literature using a population, context, and concept framework.

Infectious disease physicians in England have been diagnosing and managing occasional cases of viral hemorrhagic fever since 1971, including the United Kingdom's first case of Ebola virus disease in 1976. Specialist isolation facilities to provide safe and effective care have been present since that time. Following the emergence of Middle East respiratory syndrome (MERS) in 2012, and the avian influenza A (H7N9) outbreak in 2013, and the 2014-2016 Ebola virus disease outbreak in West Africa, clinical and public health preparedness and response pathways in England have been strengthened for these types of diseases, now called high-consequence infectious diseases (HCIDs).

We sought to remedy the limited guidance that is available to support the resuscitation of patients with the Impella Cardiac Power (CP) and 5.0 devices during episodes of cardiac arrest or life-threatening events that can result in haemodynamic decompensation. In a specialist tertiary referral centre we developed, by iteration, a novel resuscitation algorithm for Impella emergencies, which we validated through simulation and assessment by our multi- disciplinary team.

Corticotropin-releasing factor (CRF, encoded by ) signaling is thought to play a critical role in the development of excessive alcohol drinking and the emotional and physical pain associated with alcohol withdrawal. Here, we investigated the parasubthalamic nucleus (PSTN) as a potential source of CRF relevant to the control of alcohol consumption, affect, and nociception in mice. We identified PSTN neurons as a neuronal subpopulation that exerts a potent and unique influence on behavior by promoting not only alcohol but also saccharin drinking, while PSTN neurons are otherwise known to suppress consummatory behaviors.

Objectives: Surgery through a single port may be less painful because access is supplied by 1 intercostal nerve or more painful because multiple instruments are used in 1 port. We analyzed data collected from the video-assisted thoracoscopic surgery group of a randomized controlled trial to compare differences in pain up to 1 year.

Methods: Groups were compared in a prespecified exploratory analysis using direct (regression) and indirect comparison (difference with respect to thoracotomy).

The parasubthalamic nucleus (PSTN) is activated by refeeding after food deprivation and several PSTN subpopulations have been shown to suppress feeding. However, no study to date directly addressed the role of PSTN neurons activated upon food access in the control of ensuing food consumption. Here we identify consumption latency as a sensitive behavioral indicator of PSTN activity, and show that, in hungry mice, the ensemble of refeeding-activated PSTN neurons drastically increases the latency to initiate refeeding with both familiar and a novel, familiar food, but does not control the amount of food consumed.

Article Synopsis
  • Pectus defects, which occur in about 1 in 250 people, include conditions where the sternum either sinks in (excavatum) or protrudes out (carinatum), impacting some individuals psychologically and physiologically.
  • Most cases are mild and don't hinder daily activities, but some patients experience lower self-esteem and depression, avoiding social situations due to physical appearance issues.
  • Treatment options vary from supportive care and psychological support to non-surgical methods like bracing, as well as surgical options like the Nuss and Ravitch procedures for severe cases, with many patients only needing supportive care.

In rodents with unilateral ablation of neurons supplying dopamine to the striatum, chronic treatment with the dopamine precursor L-DOPA induces a progressive increase of behavioral responses, a process known as behavioral sensitization. This sensitization is blunted in arrestin-3 knockout mice. Using virus-mediated gene delivery to the dopamine-depleted striatum of these mice, we find that the restoration of arrestin-3 fully rescues behavioral sensitization, whereas its mutant defective in c-Jun N-terminal kinase (JNK) activation does not.
