Impairment of respiratory function after open cholecystectomy may cause atelectasis and hypoxemia. Clinical experience shows evidence for easier recovery after laparoscopic operation. Postoperative respiratory function using spirometric tests was assessed in 50 patients with simple symptomatic cholecystolithiasis submitted either to open or laparoscopic cholecystectomy and revealed less impairment of respiratory function in the laparoscopic group.

Thick skin and thicker arteries: case report on a rare cause of hypertension.
Pediatr Nephrol

Department of Paediatric Nephrology, Christian Medical College, Vellore, India.
Renovascular hypertension is the second leading cause of hypertension. Twenty-seven genes have been attributed to monogenic renovascular hypertension at present. We present a 15-year-old boy with facial dysmorphism, thick skin and renovascular hypertension with a novel gain-of-function variant in SMAD4 gene suggesting Myhre syndrome.

The mechanisms that drive placental dysfunction in pregnancies complicated by hypoxia and fetal growth restriction remain poorly understood. Changes to mitochondrial respiration contribute to cellular dysfunction in conditions of hypoxia and have been implicated in the pathoaetiology of pregnancy complications, such as pre-eclampsia. We used bespoke isobaric hypoxic chambers and a combination of functional, molecular and imaging techniques to study cellular metabolism and mitochondrial dynamics in sheep undergoing hypoxic pregnancy.

Department of Pediatrics, Hasbro Children's Hospital, Providence, Rhode Island, USA.
Objectives: To examine the extent to which asthma symptom concordance (ASC) or discordance (ASD) is associated with sleep outcomes in children with persistent asthma. Also, to investigate whether the association between ASC and sleep outcomes varies as a function of children's level of asthma control and severity.
Methods: A retrospective data analysis of Project NAPS (Nocturnal Asthma and Performance in School), an observational study which examined asthma and sleep outcomes in children with persistent asthma.
Dendritic alterations precede age-related dysphagia and nucleus ambiguus motor neuron death.

Motor neurons (MNs) within the nucleus ambiguus innervate the skeletal muscles of the larynx, pharynx and oesophagus, which are essential for swallow. Disordered swallow (dysphagia) is a serious problem in elderly humans, increasing the risk of aspiration, a key contributor to mortality. Despite this importance, very little is known about the pathophysiology of ageing dysphagia and the relative importance of frank muscle weakness compared to timing/activation abnormalities.

Background: Photodynamic therapy (PDT) is a noninvasive cancer treatment that works by using light to stimulate the production of excessive cytotoxic reactive oxygen species (ROS), which effectively eliminates tumor cells. However, the therapeutic effects of PDT are often limited by tumor hypoxia, which prevents effective tumor cell elimination. The oxygen (O) consumption during PDT can further exacerbate hypoxia, leading to post-treatment adverse events.
