RESUMO
Background: In human immunodeficiency virus (HIV)-infected patients on combination antiretroviral therapy (cART), lipodystrophy shares many similarities with metabolic syndrome, but only metabolic syndrome has objective classification criteria. We examined adipose tissue changes related to lipodystrophy and metabolic syndrome to clarify whether it may be acceptable to focus diagnosis on metabolic syndrome rather than lipodystrophy. Methods: This is a cross-sectional study of 60 HIV-infected men on cART and 15 healthy men. We evaluated lipodystrophy (clinical assessment) and metabolic syndrome (JIS-2009). We compared adipocyte size, leukocyte infiltration, and gene expression in abdominal subcutaneous adipose tissue biopsies of patients with and without lipodystrophy and with and without metabolic syndrome. Results: Lipodystrophy was only associated with increased macrophage infiltration (P = .04) and adiponectin messenger ribonucleic acid ([mRNA] P = .008), whereas metabolic syndrome was associated with larger adipocytes (P < .0001), decreased expression of genes related to adipogenesis and adipocyte function (P values between <.0001 and .08), increased leptin mRNA (P = .04), and a trend towards increased expression of inflammatory genes (P values between .08 and .6). Conclusions: Metabolic syndrome rather than lipodystrophy was associated with major unfavorable abdominal subcutaneous adipose tissue changes. In a clinical setting, it may be more relevant to focus on metabolic syndrome diagnosis in HIV-infected patients on cART with regards to adipose tissue dysfunction and risk of cardiometabolic complications.

INTRODUCTION: Video-assisted thoracoscopic surgery (VATS) is a minimally invasive procedure. Despite being less invasive than thoracotomy, post-operative pain remains a significant clinical problem. The aim of this study was to investigate if perioperative intravenous (IV) dexamethasone improves pain management in VATS. METHODS: Thirty-seven patients undergoing VATS with confirmed or suspected lung cancer were enrolled. The first 20 patients received standard care (Group 1) and the following 17 patients received standard care with addition of IV dexamethasone 8 mg (Group 2). The primary outcome was total opioid consumption during the first 24 hours after surgery. RESULTS: The baseline characteristics between groups were comparable. After adjusting for gender and duration of surgery, the median difference of total equianalgesic dose of opioid was 23 mg (p = 0.005). Group 2 had a significantly lower median pain score at rest. The first opioid dose was administered earlier in Group 1: 1.5 hours compared with to 6.9 hours in Group 2 (p = 0.020). Time to full mobilisation was longer in Group 1, with a mean of 12 hours (p = 0.018). CONCLUSION: This study suggests that addition of IV dexamethasone in VATS may reduce the need for opioids and facilitate early mobilisation. FUNDING: The study was funded by the Department of Clinical Medicine, Aalborg University, Aalborg, Denmark TRIAL REGISTRATION. The study is registered with ClinicalTrials.gov (NCT04633850). The study was conducted in accordance with the Declaration of Helsinki and all participants provided written consent.

Harlequin syndrome is a rare syndrome characterized by hemifacial flushing and altered facial sweating, with only a few case reports related to intercostal blockades. We present a case of Harlequin syndrome in a 65-year-old woman after intercostal blockade for video-assisted thoracoscopic lobectomy. One hour postoperatively, the patient became nauseated and presented with flushing of the right half of the face with a clear line of demarcation. Within 3 hours, the flushing disappeared. In this case report, we discuss Harlequin syndrome in relation to intercostal blockade and encourage clinicians to consider this syndrome in the differential diagnosis when encountering similar symptoms.

OBJECTIVES: The objective of this longitudinal cohort study was to investigate if preoperative pain mechanisms, anxiety, and depression increase risk of developing chronic post-thoracotomy pain (CPTP) after lung cancer surgery. METHODS: Patients with suspected or confirmed lung cancer undergoing surgery by either video-assisted thoracoscopic surgery or anterior thoracotomy were recruited consecutively. Preoperative assessments were conducted by: quantitative sensory testing (QST) (brush, pinprick, cuff pressure pain detection threshold, cuff pressure tolerance pain threshold, temporal summation and conditioned pain modulation), neuropathic pain symptom inventory (NPSI), and the Hospital Anxiety and Depression Scale (HADS). Clinical parameters in relation to surgery were also collected. Presence of CPTP was determined after six months and defined as pain of any intensity in relation to the operation area on a numeric rating scale form 0 (no pain) to 10 (worst pain imaginable). RESULTS: A total of 121 patients (60.2â¯%) completed follow-up and 56 patients (46.3â¯%) reported CPTP. Development of CPTP was associated with higher preoperative HADS score (p=0.025), higher preoperative NPSI score (p=0.009) and acute postoperative pain (p=0.042). No differences were observed in relation to preoperative QST assessment by cuff algometry and HADS anxiety and depression sub-scores. CONCLUSIONS: High preoperative HADS score preoperative pain, acute postoperative pain intensity, and preoperative neuropathic symptoms were was associated with CPTP after lung cancer surgery. No differences in values of preoperative QST assessments were found. Preoperative assessment and identification of patients at higher risk of postoperative pain will offer opportunity for further exploration and development of preventive measures and individualised pain management depending on patient risk profile.

AIM: To present the results from 16 years of nationwide cooperation between the Danish Airforce Search and Rescue Service and a Tertiary Heart Centre for the classification and treatment of accidental hypothermia. METHODS: A mobile extracorporeal membrane oxygenation (ECMO) retrieval team was developed and could be contacted for nationwide advice and if indicated retrieval and/or treatment of patients by means of ambulance and/or helicopter. Accidental hypothermia was classified as mild, moderate, and severe, corresponding to awake, unconscious, and lifeless. The exact temperature was not considered relevant in the primary assessment. The mild group was treated with blankets and minimal invasive with warm i.v. infusions. The moderate group was primarily treated with an ABC approach, and if circulation was unstable due to arrhythmias or bleeding, invasive warming was performed with pleural lavage under ECMO preparedness. The severe group was treated with CPR followed by ECMO. All patients were examined for underlying disorders. RESULTS: The team was involved in 204 patients, but for 47 patients treatment was stopped as they were considered beyond therapeutic reach, leaving 157 treated patients with 108 (69%) survivors. Among 54 ECMO patients, 21 (39%) survived to hospital discharge. CONCLUSIONS: We successfully implemented a simplified classification of accidental hypothermia and initiated a nationwide cooperation for retrieval and/or treatment of accidental hypothermic patients.

OBJECTIVE: Soluble CD163 (sCD163) is a new marker of obesity-related metabolic complications. sCD163 and CD163 mRNA were investigated in relation to the fat distribution at baseline and 12 months after Roux-en-Y gastric bypass (RYGB). METHODS: Thirty-one obese subjects (BMI: 42.3 ± 4.7 kg/m(2)) were enrolled. Subcutaneous (SAT) and visceral adipose tissue (VAT) volume were determined by MRI, intrahepatic lipid content (IHL) by MR-spectroscopy, and body composition by DXA. Fasting blood samples and adipose tissue samples were obtained, and ELISA and RT-PCR were performed. RESULTS: RYGB-induced weight loss (36 ± 11 kg) was accompanied by a significant reduction in sCD163 (2.1 ± 0.8 mg/l vs. 1.7 ± 0.7 mg/l), SAT, VAT, and IHL (all, P < 0.001). At baseline, sCD163 was associated with VAT (r = 0.40, P < 0.05) but not with SAT or IHL. Moreover, CD163 mRNA was significantly upregulated in VAT compared with SAT at baseline (P < 0.05) and significantly downregulated in SAT after RYGB (P < 0.001). ΔsCD163 was significantly associated with ΔIHL after RYGB compared with baseline (r = 0.40, P < 0.05). CONCLUSIONS: RYGB-induced weight loss results in a reduction of sCD163 and CD163 mRNA. The association between ΔsCD163 and ΔIHL may reflect a reduction in sCD163-producing Kupffer cells in the liver. Moreover, sCD163 may be a marker of "unhealthy" fat distribution in obese subjects.

INTRODUCTION: A positive interferon-gamma release assay (IGRA) is regarded as proof of latent Mycobacterium tuberculosis infection. We conducted an evaluation of the IGRA test "T-SPOT.TB" to test its performance during clinical routine use by analysing the positivity rate and odds, effect of season and sensitivity. MATERIAL AND METHODS: Data from T-SPOT.TB testing together with age and test indications (anti-tumour necrosis factor alpha (TNFα) candidate, contact investigation or suspicion of tuberculosis (TB)) were combined with mycobacteria culture results. RESULTS: A total of 1,809 patients were tested. Conclusive results were achieved for 1,780 patients (98.4%). Among these, 4.6% of anti-TNFα candidates, 19.3% of contacts and 24.4% of TB suspects tested positive. Compared with anti-TNFα candidates, the odds for a positive result were significantly higher for contact investigations (odds ratio (OR), mean (95% confidence interval): 4.93 (3.11-7.81)) and TB suspects (OR: 6.83 (4.33-10.77)). Elevated odds of an inconclusive test were found during autumn and winter periods (OR: 2.53 (1.58-4.05)) and for patients > 75 years of age (OR: 2.66 (1.43-4.94)) and < 6 years of age (OR: 3.35 (1.58-7.09)). In all, 41 of 43 culture-verified M. tuberculosis infections tested positive with one false negative. CONCLUSION: During routine testing, inconclusive tests were rare, but more frequent during autumn/winter periods and for patients < 6 and > 75 years of age. The T-SPOT.TB showed a high sensitivity in culture-verified TB, although false negative results did occur. FUNDING: not relevant. TRIAL REGISTRATION: not relevant.
