In this paper gold nanorings (NRs) are applied as particularly well-suited sensing elements for mapping the radially symmetric electric fields in the high numerical aperture focus of cylindrical vector beams. The optical properties of gold nanorings are analyzed by a combination of extinction and single particle dark field spectroscopy as well as confocal photoluminescence (PL) imaging. The results are compared to numerical calculations. The in-plane components in the focus of the cylindrical vector beams are estimated through the PL intensity distributions of the NRs...

Meralgia paresthetica (MP) is a rare lateral femoral cutaneous nerve-(LFCN)-mononeuropathy. Treatment for this disorder includes conservative and operative approaches; the latter is considered if conservative therapy fails. The most commonly used surgical approaches are decompression/neurolysis and avulsion/neurectomy. However, there are no definitive guidelines on the optimal surgical approach to be used. The purpose of this study was to evaluate the outcome of surgical decompression of the LFCN for the treatment of persistent MP with preservation of sensation along the distribution of the LFCN...

Nuclear receptors (NRs) are a family of transcription factors that regulate numerous physiological processes, such as metabolism, reproduction, inflammation, as well as the circadian rhythm. NRs sense changes in lipid metabolite levels to drive differential gene expression, producing distinct physiologic effects. This is an allosteric process whereby binding a cognate ligand and specific DNA sequences drives the recruitment of diverse transcriptional coregulators at chromatin and ultimately transactivation or transrepression of target genes...

The incidence of chronic postoperative abdominal pain (CPAP) after abdominal surgery is substantial and decreases overall quality of life. One in three patients report to have pain-related interference with mood, sleep and enjoyment of life and 12% visit the emergency department for pain related symptoms. Previous studies lack data on preoperative health and pain status, or are limited by small patient samples. The aim of this study is to assess risk factors for CPAP and gastrointestinal complaints six months after surgery...

BACKGROUND: The intensity of postoperative pain is characterized by large interindividual variability. Furthermore, strong postoperative pain is known to influence physical recovery after surgery. High (preoperative) pain expectation and pre-existing pain, which are associated with pain-related disability (impairing pain) are risk factors for strong postoperative pain. They can be determined with the Lübeck Pain Risk Questionnaire used for the first time in this study. The aim of this study was to explore the hypothesis that patients with a combination of the characteristics (1) preoperative impairing pain and (2) high pain expectation are more likely to have strong postoperative pain...

Background and Aims: Adductor canal block (ACB) is now an established component of multimodal analgesia for knee replacement surgery and is slowly replacing femoral nerve block (FNB). It is also gaining popularity for providing pain relief in knee arthroscopies including anterior cruciate ligament reconstruction surgery (ACLR). Data is lacking from the Indian subcontinent on comparing ACB to the traditional FNB for ACLR. Hence, we conducted the present study to compare ACB and FNB in ACLR under general anesthesia...

BACKGROUND: The Nutritional Risk Screening 2002 (NRS-2002) is a widely recommended nutrition risk indicator. Two cut-offs have been proposed for intensive care unit (ICU) patients to classify nutrition risk: ≥3-<5, at risk and ≥5, high risk. To date, no study has directly compared these cut-offs. The aim of this study is to compare the NRS-2002 ICU nutrition risk cut-offs as predictors of clinical outcomes including infections, ICU and hospital mortality, length of stay (LOS), duration of mechanical ventilation (MVd), weaning failure, tracheotomy for prolonged MVd, and chronic critical illness (CCI)...

The postoperative pain management in open thoracotomy is very crucial as the effective analgesia can prevent respiratory and thrombotic complications and lead to early mobilization and discharge. The thoracic epidural analgesia is the gold standard in such surgeries; however, there are few adverse effects such as hypotension, dural puncture, and contralateral block that always warrants safer alternative. Recently, with the advent of ultrasound, the regional anesthetic techniques are getting more popular to avoid such complications...

Approaches are needed for the tailored assembly of plasmonic building blocks on the surface of substrates to synergistically enhance their properties. Here we demonstrate selective immobilization and assembly of gold nanorods (NRs) on substrates modified and patterned with end-grafted poly(ethylene glycol) (PEG) layers. The ligand exchange from the initial cetyltrimethylammonium bromide to sodium citrate was necessary for the immobilization of gold NRs onto PEG grafted substrates. Linear nanopatterns of PEG were fabricated using electrospun nanofibers as masks in oxygen plasma etching...
