Magnesium disorders are common in clinical practice and when present can manifest clinically as cardiovascular, neuromuscular, or other organ dysfunction. Hypomagnesemia is far more common than hypermagnesemia, which is largely seen in patients with reduced glomerular filtration rates receiving magnesium-containing medications. In addition to inherited disorders of magnesium handling, hypomagnesemia is also seen with excessive gastrointestinal or renal losses and due to medications such as amphotericin B, aminoglycosides, and cisplatin. ⋯ Replacement of magnesium can be challenging, with oral replacement strategies being generally more effective at slowly replacing body stores but intravenous replacement being more effective at treating the more life-threatening and severe cases of hypomagnesemia. We conducted a thorough review of the literature using PubMed (1970-2022) and the search terms magnesium, hypomagnesemia, drugs, medications, treatment, and therapy. In the absence of clear data on optimal management of hypomagnesemia, we have made recommendations on magnesium replacement based on our clinical experience.

Utilization of Wearable Pedometer Devices in the Perioperative Period: A Qualitative Systematic Review.
Functional capacity assessment is important for perioperative risk stratification; however, there are currently limited options for objective and economical functional capacity evaluation. Pedometer functions are now widely available in mobile devices and offer a nonintrusive and objective approach to measuring patient activity level over time. Therefore, we conducted this systematic review to assess the value of pedometer readings in predicting perioperative outcomes. ⋯ In addition, in-hospital postoperative pedometer readings correlated with postdischarge complications and readmissions. Perioperative pedometer data demonstrated consistent and biologically plausible association with perioperative outcomes. Further studies are needed to validate the use of pedometer in the perioperative period and to identify the optimal approach for its use to potentially improve patient outcomes.

In the past decade, the medical management of people with cystic fibrosis (pwCF) has changed with the development of small molecules that partially restore the function of the defective CF transmembrane conductance regulator (CFTR) protein and are called CFTR modulators. Ivacaftor (IVA), a CFTR potentiator with a large effect on epithelial ion transport, was the first modulator approved in pwCF carrying gating mutations. Because IVA was unable to restore sufficient CFTR function in pwCF with other mutations, two CFTR correctors (lumacaftor and tezacaftor) were developed and used in combination with IVA in pwCF homozygous for F508del, the most common CFTR variant. ⋯ Recent clinical trials and real-world studies suggest that benefits of HEMT could even prove greater when used earlier in life (i.e., in younger children and infants). This article shortly reviews the past 10 years of development and use of CFTR modulators. Effects of HEMT on extrapulmonary manifestations and on CF demographics are also discussed.

Poor family functioning has been reported to be associated with the severity of chronic pain in outpatients, but the association has not been fully addressed in general populations. The present study aimed to examine the association between family dysfunction levels and the presence of chronic pain in a community-dwelling Japanese population. ⋯ A biopsychosocial burden due to family relationships could worsen the clinical presentation of pain. Social support or family therapy for dysfunctional families would be a potential initiative for the prevention or management of chronic pain.

It remains unknown why some people with diabetes develop painful neuropathies while others experience no pain. This study aimed to validate a novel method for assessing the function of small sensory nerves in diabetes to further elucidate this phenomenon. The function of large and small nerves was assessed using a novel perception threshold tracking technique in 3 well-characterized groups (n = 60) with type 1 diabetes, namely, (1) painful diabetic peripheral neuropathy (T1DM + PDPN), (2) painless diabetic peripheral neuropathy (T1DM + DPN), and (3) no neuropathy (T1DM - DPN), and healthy controls (n = 20). ⋯ The accommodation properties of stimulated fibers were different between the 2 electrodes ( P < 0.05) apart from in the group with T1DM + PDPN, where both electrodes stimulated nerves displaying properties similar to large fibers. Perception threshold tracking reveals differences in large and small nerve fiber function between the groups with and without diabetes, DPN, and pain. This indicates that the methods have potential applications in screening DPN and explore further the features differentiating painful from nonpainful DPN.
