Background Isoelectric focusing (IEF) is a method with an exquisite resolution, and coupled with affinity immunoblotting (AIB), it can provide superior sensitivity to detect monoclonal free light chains (FLC). Methods We tested the hypothesis that IEF/AIB is more sensitive and specific for monoclonal FLC detection in serum and urine samples than conventional methods, that is, electrophoresis (ELP), immunofixation (IF) and serum FLC ratio assessment. Investigation included 107 samples of 68 patients, among which 21 multiple myeloma patients were recently tested for minimal residual disease and 18 patients with AL amyloidosis. Results Monoclonal FLC were detected by IEF/AIB in 37% of serum samples negative for monoclonal FLC on ELP/IF. As for urine samples, significant advantage of the IEF/AIB over ELP/IF was not demonstrated. Considering both serum and urine results, IEF/AIB definitely revealed monoclonal FLC in 20/83 (24%) of ELP/IF-negative samples. FLC ratio was abnormally high (>1.65) in all 11 patients definitely positive for monoclonal FLC kappa by IEF/AIB but also in 16/47 (34%) IEF/AIB-negative samples. Abnormally low values (<0.26) were found only in 10/28 samples (36%) positive for monoclonal FLC lambda. Appropriate use of renal FLC ratio reference range reduced the number of presumably false positives (6/47, i.e. 13%) but not false negatives (17/28, i.e. 61%). Conclusions The IEF/AIB method is more sensitive than IF and might be used in patients with negative IF results before deciding whether to proceed to minimal residual disease testing.

Background There is limited understanding of alteration of gut microbiota and metabolome in children with sepsis/septic shock. Methods In this prospective observational study carried out in a pediatric intensive care unit of a tertiary care center from 2020 to 2022, patients aged <17 years with sepsis/septic shock and healthy children (HC) were enrolled. We characterized the gut bacterial compositions by metagenome sequencing and metabolomes by untargeted gas chromatography-mass spectrometry. The primary outcome was to compare the gut microbiota and metabolome of children with sepsis/septic shock with that of HC. The Firmicutes/ Bacteroidetes (F/B) ratio was compared between children with sepsis/septic shock and HC. Key secondary outcomes were to evaluate association of factors associated with a low F/B ratio in children with sepsis/septic shock. Results A total of 40 children (63% boys) (15 children with sepsis and septic shock and 10 healthy children) with a median (IQR) age of 5.5 (1.5, 10) years were enrolled. In the fecal microbiota, the α-diversity index including Shannon and Simpson indices of the sepsis/septic shock groups was significantly lower than that of the HC. The samples lacked beneﬁcial Biﬁdobacterium spp. and were dominated by Bacteroides, Enterobacteriaceae, and Enterococcaceae. There was reduction in short-chain fatty acids (SCFAs) in patients with sepsis/septic shock as compared to healthy children. A lower F/B ratio (≤1.57) of the gut microbiota discriminated well between children with sepsis/septic shock and HC. Factors associated with lower F/B ratio were male gender, clinical GI dysfunction, elevated inflammatory markers, and higher organ failure scores. Conclusion There were significant alterations in the gut microbiota and metabolome in children with sepsis/septic shock as compared to healthy children. Larger study is needed to confirm these exploratory findings and develop potential therapeutic targets that will improve outcomes in children with sepsis/septic shock.

Background While sudden cardiac arrest (CA) survivors are at risk for developing psychiatric disorders, little is known about the impact of preexisting mental health conditions on long-term survival or postacute healthcare utilization. We examined the prevalence of preexisting psychiatric conditions in CA patients who survived hospital discharge, characterized incidence and reason for inpatient psychiatry consultation during these patients’ acute hospitalizations, and determined the association of pre-CA depression and anxiety with hospital readmission rates and long-term survival. We hypothesized that prior depression or anxiety would be associated with higher hospital readmission rates and lower long-term survival. Methods We conducted a retrospective cohort study including patients resuscitated from in- and out-of-hospital CA who survived both admission and discharge from a single hospital between January 1, 2010, and December 31, 2017. We identified patients from our prospective registry, then performed a structured chart review to abstract past psychiatric history, prescription medications for psychiatric conditions, and identify inpatient psychiatric consultations. We used administrative data to identify readmissions within 1 year and vital status through December 31, 2020. We used multivariable Cox regressions controlling for patient demographics, medical comorbidities, discharge Cerebral Performance Category and disposition, depression, and anxiety history to predict long-term survival and hospital readmission. Results We included 684 subjects. Past depression or anxiety was noted in 24% ( n = 162) and 19% ( n = 129) of subjects. A minority of subjects ( n = 139, 20%) received a psychiatry consultation during the index hospitalization. Overall, 262 (39%) subjects had at least 1 readmission within 1 year. Past depression was associated with an increased hazard of hospital readmission (hazard ratio 1.50, 95% CI 1.11–2.04), while past anxiety was not associated with readmission. Neither depression nor anxiety were independently associated with long-term survival. Conclusions Depression is an independent risk factor for hospital readmission in CA survivors.

Authors: Sujon Hasnat , Khatun Rakiba , Mumin Jubayer 
Published: December 2023

Introduction: Non-puerperal adoptive lactation sometimes requires long preparation and substantial expense for pharmacological intervention to be successful, which are not feasible in refugee camps. Here we report two case studies of non-puerperal adoptive breastfeeding of two infants in the Rohingya Refugee Camp of Cox’s Bazar, Bangladesh. Main Issue: Two non-pregnant, non-breastfeeding caregivers with previous experience of breastfeeding brought two adopted infants—one a 12-day-old female with severe acute malnutrition, and the other a 2-day-old male with normal anthropometric measurements—to a nutritional stabilization center for feeding. After counseling, both families opted for adoptive lactation. Management: Both infants were treated with a modified Action Against Hunger protocol of in-patient management of severe acute malnutrition using the supplementary suckling technique, a procedure to feed the baby with supplementary feed. Diluted F100 was used as the supplementary feed; the energy and protein gained from it were just enough to maintain body physiology and were not responsible for any weight gain. When the infants gained weight, indicating that the caregivers were producing milk, we reduced the supplementary feed as per protocol guidelines. The caregivers were prescribed domperidone and counseled on their ability to breastfeed the infants. The cases required 35 days and 20 days, respectively, for the full establishment of breastfeeding. Conclusion: This is the first report of successful adoptive breastfeeding in a refugee camp. With proper counseling and motivation of the caregiver, induced lactation can be started without a preparatory period and with very low-cost intervention.

Objective: The goal of minimally invasive surgery is to reduce trauma to patients and improve their postoperative outcomes. In this context, the utilization of robot-assisted thoracic surgery (RATS) in the treatment of lung cancer has increased worldwide. The feasibility of single-incision major pulmonary resections by RATS was recently reported, with the objective of minimizing the surgical trauma of the traditional multiportal RATS approach. However, both techniques require intercostal incisions, potentially causing immediate and chronic pain resulting from intercostal nerve injury. To reduce postoperative pain resulting from intercostal approaches, we developed a nonintercostal, outside the thoracic cage (OTC) approach for RATS lobectomy, avoiding intercostal instrumentation. This report aims to describe the results of the first reported series of OTC subcostal RATS lobectomies. Methods: Retrospective analysis of a series of the first consecutive patients operated on using the novel OTC subcostal RATS lobectomy technique. Results: Between August and December 2022, a total of 10 consecutive cases were analyzed. The median age was 63 (55 to 84) years, the mean body mass index was 29 (24 to 45) kg/m2, and the median American Society of Anesthesiologists score was III (II to IV). No serious adverse events were observed, and there was no conversion of the surgical technique. The mean operative time was 132.6 (98 to 223) min. The median length of stay was 2 days. No pain-related complications, readmissions, or 30-day mortality were observed. Conclusions: This series demonstrates that OTC RATS lobectomy is feasible and safe. A phase I clinical trial is currently underway to prospectively assess the safety of the technique as well as its clinical relevance.

Introduction Treatment of basilar apex aneurysms will remain challenging regarding the nobility of the parent vessel and their often wide-necked configuration. With endovascular techniques being the treatment approach of choice, novel intrasaccular flow-disruption devices constitute an endovascular embolization option. In this research, we report our experiences in embolizing basilar tip aneurysms with the novel Contour device. Material and methods Retrospective analysis of eight patients after Contour implantation into a basilar apex aneurysm. Periprocedural data on intervention times, radiation dose, procedural success and complications were gathered. All patients received follow-up digital subtraction angiography after six months. Further follow-up examination results were analysed given their availability. Results Contour implantation was successful in all patients. The mean device instrumentation time was 18.8 ± 7.7 min with a mean full intervention time of 100 ± 65.8 min. The mean full procedure radiation dose was 1917 (421–5107) cGy/cm2. After six months, six aneurysms were occluded (Raymond Roy Scale (RRS) 1/2), one showed perfusion inside the device (RRS 3a) and one patient had undergone reintervention due to progression. The aneurysm with constant perfusion at six months was seen to be occluded after 24 months. Conclusion Contour device implantation is a promising feasible alternative endovascular method for embolization of intracranial aneurysms located in the basilar tip with short intervention times and low radiation dosages. Short- and medium-term follow-ups show promising results concerning aneurysm occlusion and reinterventions, however further research is needed to show long-term stability.

Published: December 2023

Background: Pregnancy-related lumbopelvic pain is a frequently reported musculoskeletal disorder, but few studies have compared data between countries. Objectives: Examine prevalence, severity, and sick leave and explore potential risk factors associated with pregnancy-related lumbopelvic pain in Italian women and compare the results to a similar study in Norway, utilizing the same questionnaire. Design: Cross-sectional Methods: Italian ( n = 481) and Norwegian women ( n = 435) were allocated from two public hospitals in Rome (Fatebenefratelli San Giovanni Calibita-Isola Tiberina) and Oslo (Oslo University Hospital), as well as four antenatal clinics in Modena (Italy). The questionnaire was completed between gestation weeks 32 and 36, addressing women’s experiences of pregnancy-related lumbopelvic pain and sick leave in current week, and retrospectively for prepregnancy, first and second trimesters. Results: In Italy and Norway, 39% and 57% of pregnant women reported pregnancy-related lumbopelvic pain, respectively, with 11% and 25% experiencing severe pregnancy-related lumbopelvic pain. Pregnancy-related lumbopelvic pain was associated with sick leave in Norway ( p < 0.01), but not in Italy ( p = 0.66) at late gestation. In both countries, women with pregnancy-related lumbopelvic pain versus those with no pregnancy-related lumbopelvic pain were more likely to be multiparous (Italy: 40% versus 31%, p = 0.06 and Norway: 53% versus 38%, p < 0.01), and have gestational weight gain above guidelines (Italy: 21% versus 13%, p = 0.02% and Norway: 27% versus 14%, p < 0.01) and previous experience of pregnancy-related lumbopelvic pain (Italy: 15% versus 2%, p < 0.01 and Norway: 31% versus 4%, p < 0.01). Maternal exercise (⩾2 times weekly) was associated with less pregnancy-related lumbopelvic pain (Italy: odds ratio = 0.33, 95% confidence interval = 0.11–1.0, p = 0.05 and Norway: odds ratio = 0.55, 95% confidence interval = 0.29–1.0, p = 0.06). Conclusion: We observed high rates of pregnancy-related lumbopelvic pain in Italy and Norway, with Norwegian women reporting the highest prevalence and severity level. While both countries had similar rates of sick leave in late gestation, an association between pregnancy-related lumbopelvic pain and sick leave was observed among Norwegian women only. Health care providers should be proactive in addressing pregnancy-related lumbopelvic pain through open communication and seeking input from pregnant individuals. However, it is essential to acknowledge that the current evidence on effective treatments remains limited and inconclusive, highlighting the need for further research in this field.

Authors: Foglietta Federica , Serpe Loredana , Canaparo Roberto 
Published: December 2023

AbstractReactive species refers to a group of chemicals, mainly reactive oxygen species (ROS) and reactive nitrogen species (RNS), that are naturally formed by cells as a byproduct of cell metabolism and regulated by various internal and external factors. Due to their highly chemical reactivity, ROS play a crucial role in physiological and pathological processes which is why studies on ROS regulation for disease treatment show attracted increasing interest. Notably, ROS are now studied as a powerful therapeutic weapon in ROS-regulating therapies such as ROS-based cytotoxic therapies mediated by ROS-increasing agents for cancer treatment. Thanks to the significant progress in nanotechnology, innovative nanoplatforms with ROS-regulating activities have been developed to look for effective ROS-related nanomedicines. In this review, studies on ROS-based cytotoxic therapies against cancer as photodynamic therapy (PDT), sonodynamic therapy (SDT), radiation therapy (RT) and chemodynamic therapy (CDT) are discussed, with a focus on the stimuli-responsive ROS-generating nanoplatforms developed for breaking the current therapeutic limits of ROS-based cytotoxic therapies. Finally, we suppose that our review on this developing field will be valuable for promoting the progress of ROS-based cytotoxic therapies not only in basic research but overall, in translational research and clinical application.

Abstract
Background
The functional roles of the Wall Associated Kinase (WAK) and Wall Associated Kinase Like (WAKL) families in cellular expansion and developmental processes have been well-established. However, the molecular regulation of these kinases in maize development is limited due to the absence of comprehensive genome-wide studies.

Results
Through an in-depth analysis, we identified 58 maize WAKL genes, and classified them into three distinct phylogenetic clusters. Moreover, structural prediction analysis showed functional conservation among WAKLs across maize. Promoter analysis uncovered the existence of cis-acting elements associated with the transcriptional regulation of ZmWAKL genes by Gibberellic acid (GA). To further elucidate the role of WAKL genes in maize kernels, we focused on three highly expressed genes, viz ZmWAKL38, ZmWAKL42 and ZmWAKL52. Co-expression analyses revealed that their expression patterns exhibited a remarkable correlation with GA-responsive transcription factors (TF) TF5, TF6, and TF8, which displayed preferential expression in kernels. RT-qPCR analysis validated the upregulation of ZmWAKL38, ZmWAKL42, ZmWAKL52, TF5, TF6, and TF8 following GA treatment. Additionally, ZmWAKL52 showed significant increase of transcription in the present of TF8, with ZmWAKL52 localizing in both the plasma membrane and cell wall. TF5 positively regulated ZmWAKL38, while TF6 positively regulated ZmWAKL42.

Conclusions
Collectively, these findings provide novel insights into the characterization and regulatory mechanisms of specific ZmWAKL genes involved in maize kernel development, offering prospects for their utilization in maize breeding programs.

Published: December 2023

Abstract
Background
Capparis spinosa L. is a typical desert plant that is resistant to high temperatures and drought, and at the same time is rich in medicinal and food values. The objective of this study is to explore the variations in nutrient composition, morphological characteristics, and SDS-PAGE patterns of caper seeds from different provenances, aiming to provide insights for the selection of superior seed provenances.

Results
In this experiment, there were significant differences in the morphological characteristics and major nutritional components of caper seeds from different provenances. Seeds from the YKL (Karayagaqi Township, Yining County) and YKG (G218, KashiTown, Yining County) regions were larger in size compared to seeds from other regions. Among the four measured nutritional components, crude fat had the highest content, especially in the YKL and YKG region. The results of correlation analysis showed that crude fat was negatively correlated with soluble sugar and soluble protein but significantly positively correlated with starch content. As longitude increased from east to west, the morphological characteristics gradually increased. Based on the principal component analysis of all the parameters of the seeds, the eight provenances could be classified into three groups. HM (Hami), TGS (S202, Gaochang District, Turpan), HYW (Wubao Town, Yizhou District, Hami), TQQ (Qiquanhu Town, Turpan), and TLF (Turpan) were a group with higher soluble protein, soluble sugar, and water content. YKL and YKG were in one group, which had larger seed grains with high crude fat and starch content. AKS (Aksu) was in a separate group. The protein fractions from seeds of eight regions were extracted using Osborne fractionation method, it was found that glutelin content was the highest, while albumin content was the lowest. After these proteins were analyzed by SDS-PAGE, the electrophoretic patterns showed that the protein molecular weights were relatively small, and there were differences in protein bands among different provenances.

Conclusion
According to the PCA results, the eight seed provenances could be divided into three groups. There were both geographically distant ones clustered into one group, and those close to each other were also divided into one group. There were differences in seed morphology, nutrient content and SDS-PAGE profiles among the different seed sources. This difference might be caused by a combination of geographic and climatic factors. In addition, YKL and YKG were roughly selected as good seed provenances, which provided a theoretical basis for the development of C. spinosa L. germplasm resources.
