BACKGROUND (RATIONALE/PURPOSE/OBJECTIVE): Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used to temporary control non-compressible truncal hemorrhage (NCTH) as bridge to definitive surgical treatment. The dependence on radiography for safe balloon positioning is one factor that limits the extended use of REBOA in civilian and military pre-hospital settings. We aimed to determine standardized sex and age-based variable-distance catheter insertion lengths for accurate REBOA placement without initial fluoroscopic confirmation.
METHODS: Contrast enhanced CT-scans from a representative sample of a Dutch non-trauma population were retrospectively analyzed. Intravascular distances were measured from the bilateral common femoral artery access points (FAAP) to the middle of the aortic occlusion zones and accompanying boundaries. Means and 95% confidence intervals for the distances from the FAAPs to the boundaries and mid-zone III were calculated for all (combined) sex and age-based subgroups. Optimal insertion lengths and potentially safe regions were determined for these groups. Bootstrap analysis was performed in combination with a 40-mm long balloon introduction simulation to determine error-rates and REBOA placement accuracy for the general population.
RESULTS: In total, 1354 non-trauma patients (694 females) were included. Vascular distances increased with age and were longer in males. The iliofemoral trajectory was 7 mm longer on the right side. The optimal zone I catheter insertion length would be 430 mm. Optimal zone III catheter insertion lengths showed up to 30 mm difference, ranging between 234 and 264 mm. Statistically significant and potentially clinically relevant differences were observed between the anatomical distances and necessary introduction depths for each subgroup.
CONCLUSION: This is the first study to compare aortic morphology and intravascular distances between combined sex and age-based subgroups. As zone III length was consistent, length variability and elongation seem to mainly originate in the iliofemoral trajectory and zone II. The optimal zone I catheter insertion length would be 430 mm. Optimal zone III catheter insertion ranged between 234 and 264 mm. These standardized variable-distance insertion lengths could facilitate safer fluoroscopy-free REBOA in austere, pre-hospital settings.
More than 4 million patients receive a blood transfusion each year in the United States, many of them suffer from congestive heart failure. The reported prevalence of anemia in CHF is unknown, ranges widely from 4% to 70%, due to a lack of an established, consistent definition of anemia in CHF.

Treating CHF patients with furosemide prior to blood transfusion became a common practice, even though no randomize clinical trial had examine this issue. Nand et al. measured the pulmonary capillary wedge pressures in 20 adults with chronic severe anemia (Hg \<6 mg/dl) and no systemic disease before and after transfusion of 700ml of whole blood. Ten of these patients were treated with furosemide (40 mg intra-venous) immediately prior the transfusion. The PCWP had increased significantly among patient who did not receive the furosemide and decreased by 3.75% among patients in the furosemide group, although this change was not was statistically significant. In another study, the same group of Nand et al. measured the PCWP among 40 chronic anemia patients receiving blood transfusion. None of the patients suffered from cardiopulmonary disease. The patients were randomly divided into 4 groups: the difference between the first 3 groups was the speed of the transfusion (2 ml/min, 5 ml/min and 10 ml/min). The fourth group patients were treated with 40 mg of furosemide before the transfusion was given in a rate of 5 ml/min. The PCWP increased significantly in the first 3 groups, with the rise being proportionately greater with faster transfusions (15.8, 20.9 and 32.2% in groups A, B and C, respectively). In the furosemide group, however, the PCWP decreased significantly by 21.7%.
AIM: Locally advanced rectal cancer (LARC) is commonly treated with neoadjuvant chemoradiotherapy (nCRT) and total mesorectal excision (TME) to reduce local recurrence (LR) and improve survival. However, LR, particularly associated with lateral lymph node (LLN) involvement, remains a concern. The aim of this study was to investigate preoperative factors associated with LLN involvement and their impact on LR rates in LARC patients undergoing nCRT and curative surgery.
METHOD: This multicentre retrospective study, including four academic high-volume institutions, involved 301 consecutive adult LARC patients treated with nCRT and curative surgery between January 2014 and December 2019 who did not undergo lateral lymph node dissection (LLND). Baseline and restaging pelvic MRIs were evaluated for suspicious LLNs based on institutional criteria. Patients were divided into two groups: cLLN+ (positive nodes) and cLLN- (no suspicious nodes). Primary outcome measures were LR and lateral local recurrence (LLR) rates at 3 years.
RESULTS: Among the cohort, 15.9% had suspicious LLNs on baseline MRI, and 9.3% had abnormal LLNs on restaging MRI. At 3 years, LR and LLR rates were 4.0% and 1.0%, respectively. Ten out of 12 (83.3%) patients with LR showed no suspicious LLNs at the baseline MRI. Abnormal LLNs on MRI were not independent risk factors for LR, distant recurrence or disease-free survival.
CONCLUSION: Abnormal LLNs on baseline and restaging MRI assessment did not impact LR and LLR rates in this cohort of patients with LARC submitted to nCRT and curative TME surgery.
A phase 3, multi-center, three-arm, randomized, open-label study was conducted in previously untreated patients with advanced renal cell carcinoma (clear cell and non-clear cell histologies). The objectives were to compare Overall Survival (OS), Progression-Free Survival (PFS), Objective Response Rate (ORR), and safety in patients receiving IFN-α to those receiving TORISEL or TORISEL plus IFN-α. Patients in this study had 3 or more of 6 pre-selected prognostic risk factors (less than one year from time of initial renal cell carcinoma diagnosis to randomization, Karnofsky performance status of 60 or 70, hemoglobin less than the lower limit of normal, corrected calcium of greater than 10 mg/dL, lactate dehydrogenase >1.5 times the upper limit of normal, more than one metastatic organ site). Patients were stratified for prior nephrectomy status within three geographic regions and were randomly assigned (1:1:1) to receive IFN-α alone (n = 207), TORISEL alone (25 mg weekly; n = 209), or the combination arm (n = 210).

The ITT population for this interim analysis included 626 patients. Demographics were comparable between the three treatment arms with regard to age, gender, and race. The mean age of all groups was 59 years (range 23–86). Sixty-nine percent were male and 31% were female. The racial distribution for all groups was 91% White, 4% Black, 2% Asian, and 3% other. Sixty-seven percent of patients had a history of prior nephrectomy.

The median duration of treatment in the TORISEL arm was 17 weeks (range 1–126 weeks). The median duration of treatment on the IFN arm was 8 weeks (range 1–124 weeks).

There was a statistically significant improvement in OS (time from randomization to death) in the TORISEL 25 mg arm compared to IFN-α. The combination of TORISEL 15 mg and IFN-α did not result in a significant increase in OS when compared with IFN-α alone. Figure 1 is a Kaplan-Meier plot of OS in this study. The evaluations of PFS (time from randomization to disease progression or death) and ORR, were based on blinded independent radiologic assessment of tumor response. Efficacy results are summarized in Table 4.

BACKGROUND AND AIMS: Why only half of the idiopathic peripheral neuropathy (IPN) patients develop neuropathic pain remains unknown. By conducting a proteomics analysis on IPN patients, we aimed to discover proteins and new pathways that are associated with neuropathic pain.
METHODS: We conducted unbiased mass-spectrometry proteomics analysis on blood plasma from 31 IPN patients with severe neuropathic pain and 29 IPN patients with no pain, to investigate protein biomarkers and protein-protein interactions associated with neuropathic pain. Univariate modeling was done with linear mixed modeling (LMM) and corrected for multiple testing. Multivariate modeling was performed using elastic net analysis and validated with internal cross-validation and bootstrapping.
RESULTS: In the univariate analysis, 73 proteins showed a p-value <.05 and 12 proteins showed a p-value <.01. None were significant after Benjamini-Hochberg adjustment for multiple testing. Elastic net analysis created a model containing 12 proteins with reasonable discriminatory power to differentiate between painful and painless IPN (false-negative rate 0.10, false-positive rate 0.18, and an area under the curve 0.75). Eight of these 12 proteins were clustered into one interaction network, significantly enriched for the complement and coagulation pathway (Benjamini-Hochberg adjusted p-value = .0057), with complement component 3 (C3) as the central node. Bootstrap validation identified insulin-like growth factor-binding protein 2 (IGFBP2), complement factor H-related protein 4 (CFHR4), and ferritin light chain (FTL), as the most discriminatory proteins of the original 12 identified.
INTERPRETATION: This proteomics analysis suggests a role for the complement system in neuropathic pain in IPN.
Aplastic anemia (AA) is a group of clinical syndromes caused by a significant decrease in bone marrow hematopoietic tissue from different etiologies, resulting in hematopoietic failure. The prevalence of AA in China is 7.4 per 1 million. It peaks in the 15-25 and 60+ age groups and is more common in men than women. Treatment options are very limited. The results of a previous clinical study showed good efficacy and a high safety profile of herombopag in improving thrombocytopenia, but this result needs to be supported by more data.

In our study, patients who were willing to participate in this study and were diagnosed with transfusion-dependent non-heavy aplastic anemia were randomized to the rhTPO combined with herombopag + cyclosporine group and given rhTPO (at a dose of 1500 U by subcutaneous injection once daily for 7 d, 28 d for 3 courses) +Herombopag(10 mg/day for 3 months) + cyclosporine (3-5 mg/kg/d for 3 months). -5 mg/kg/d for at least 6 months) and Herombopag + cyclosporine (10 mg/day for 3 months) + cyclosporine (3-5 mg/kg/d for at least 6 months) in the herombopag+ cyclosporine group to observe the efficacy and safety.
Spinal cord stimulation (SCS) is a treatment option for people suffering with chronic neuropathic back and leg pain. Conventionally, patients receiving SCS are provided with tonic stimulation parameters, where the frequency of electrical pulses is set at 40-60Hz. The major side effect of tonic SCS parameters is the onset of paraesthesia, a tingling or pins and needles sensation within the target region, which can cause discomfort for some patients. However, newer methods include high-frequency stimulation (HF) which is able to provide paraesthesia free stimulation, ultimately providing better patient tolerability. HF stimulation is widely offered to patients with SCS as part of routine clinical practice. However, the effect on pathways in the brain remains to be characterised. This study therefore aims to investigate the clinical response to three frequency parameters 40Hz, 4000Hz and 10000Hz and also explore the brain imaging changes using PET-CT scans. The response to these stimulator settings on health related quality of life will also be measured using validated questionnaires.

20 patients who are deemed suitable for SCS as part of NICE guidelines 159 pathway will be recruited for the study. All patients will have a baseline PET-CT scan and undergo first stage of SCS where they will be offered tonic 40Hz settings as part of trial stimulation. If successful (\>50% improvement in pain scores) patients will be offered second stage and continue to receive 40Hz stimulation for 4 weeks. After a second PET-CT scan they are randomised to receive either 4000Hz or 10000Hz stimulation for 4 more weeks, then cross-over treatment for another 4 weeks. PET-CT scans will be performed between each level of stimulation and at the end of the study (4 in total).

Testosterone gel was evaluated in a randomized, five-treatment, single-center, controlled, within-subject comparison study with healthy subjects using a cumulative irritation patch test design. Thirty-three (33) subjects completed the study involving testosterone gel, a comparator control product, vehicle, and positive and negative controls. All five treatments were applied to the skin separately with an occlusive patch. Each subject received a set of 5 patches, once daily for 21 consecutive days. Evaluation of dermal reactions at the application sites were assessed every day at the time of removal of each patch using an established ordinal (6-point) scoring system. Testosterone gel showed no evidence of significant irritation and was statistically significantly less irritating than the positive control (P<0.001).
The initial dose of fentanyl buccal tablet is always 100 mcg with the only exception being patients already using ACTIQ.

Patients on ACTIQ

  1. For patients being converted from ACTIQ, prescribers must use the Initial Dosing Recommendations for Patients on ACTIQ table below (Table 1). The doses of fentanyl buccal tablet in this table are starting doses and not intended to represent equianalgesic doses to ACTIQ. Patients must be instructed to stop the use of ACTIQ and dispose of any remaining units.
  2. For patients converting from ACTIQ doses equal to or greater than 600 mcg, titration should be initiated with the 200 mcg fentanyl buccal tablet and should proceed using multiples of this tablet strength.



Repeat Dosing

  1. In cases where the breakthrough pain episode is not relieved after 30 minutes, patients may take ONLY ONE additional dose using the same strength for that episode. Thus patients should take a maximum of two doses of fentanyl buccal tablet for any episode of breakthrough pain.
  2. Patients MUST wait at least 4 hours before treating another episode of breakthrough pain with fentanyl buccal tablet.
Term and healthy newborns on maternity wards in SAINT-ANTOINE hospital are checked everyday for jaundice with bilirubinometer JM-103®. If indicated (nomogram included in patient charts), a plasmatic bilirubin level is performed. If the baby is two days old or more with a bilirubin level indicating standard phototherapy (by opposition to intensive phototherapy), the parents are informed of the research protocol and after obtention of parental consent, the baby is included. The newborn is admitted in the neonatology unit and randomised in one of the three phototherapy devices group. Plasmatic bilirubin levels are checked at 6,12 and 24 and 48 hours of phototherapy. At 12 hours of phototherapy, a biological checking is performed to address the etiology of the jaundice. The next plasmatic bilirubin level is performed at 72h after inclusion. During phototherapy treatment the baby is continuously monitored. Phototherapy is stopped when bilirubin level is below 200µmol/l. If the bilirubin level is increasing under one of this ramps or does not decrease at H24, the baby will be immediately move on intensive phototherapy and participation at the research protocol interrupted. Twenty four hours after the end of phototherapy treatment, plasmatic bilirubin level is checked to confirm the end of jaundice and statement is made for jaundice origin. The total duration of participation of a baby at this study is 72 hours.
In group B, newborns received placebo. The protocol for dosing was (1) first dose of 1 mg/kg/dose within 30 minutes admission or within 12 hours of delivery (whichever earlier), (2) Dosing every six hours for a maximum of 8 doses.
Participants with Parasympathetic Nervous System (PNS) and Sympathetic Nervous System (SNS) Indexes values ''PNS\<-2, SNS\>2'' according to the results of heart rate variability measurements were included in this group. Then bilateral transcutaneous auricular vagus nerve stimulation was performed.
BACKGROUND: Vaccine breakthrough SARS-CoV-2 infections are common and of clinical and public health concern. However, little is known about the immunological characteristics of patients hospitalized due to these infections. We aimed to investigate and compare immune cell subpopulations and induced immune responses in vaccinated and non-vaccinated patients hospitalized with severe COVID-19.
METHODS: A nested case-control study on adults (≥ 18 years) who received at least two doses of a mRNA-COVID-19 vaccine and were hospitalized with SARS-CoV-2 breakthrough infections and severe COVID-19 between January 7, 2021, and February 1, 2022, were eligible for inclusion. Age- and sex-matched non-vaccinated controls were identified. Immunophenotyping was performed using a custom-designed 10-color flow cytometry prefabricated freeze-dried antibody panel (DuraClone, Beckman Coulter (BC), Brea, Calif). TruCulture (Myriad RBM, Austin, USA) was used to assess induced immune response in whole blood, revealing different critical signaling pathways as a proxy for immune function. All samples were obtained within 48 hours of admission.
RESULTS: In total, 20 hospitalized patients with severe COVID-19 and a breakthrough SARS-CoV-2 infection were included, ten vaccinated and ten non-vaccinated patients. Vaccinated patients had lower concentrations of CD19 B cells (p = 0.035), naïve CD4 T cells (p = 0.015), a higher proportion of γδ1 T cells (p = 0.019), and higher unstimulated immune cell release of IL-10 (p = 0.015).
CONCLUSION: We observed immunological differences between vaccinated and non-vaccinated patients hospitalized due to severe COVID-19 that indicate that vaccinated patients had lower B cell concentrations, lower concentrations of CD4 naïve T cells, a skewed gamma-delta V1/V2 ratio, and an exaggerated IL-10 response at admission. These results could indicate a suboptimal immune response involved in SARS-CoV-2 breakthrough infections that cause severe COVID-19 in vaccinated adults. However, the sample size was small, and further research is needed to confirm these results.
Antibiotic drug combination therapy is critical for the successful treatment of infections caused by multidrug resistant pathogens. We investigated the efficacy of β-lactam and β-lactam/β-lactamase inhibitor combinations with other antibiotics, against the hypervirulent, ceftazidime/avibactam resistant Pseudomonas aeruginosa Liverpool epidemic strain (LES) B58. Although minimum inhibitory concentrations in vitro differed by up to eighty-fold between standard and host-mimicking media, combinatorial effects only marginally changed between conditions for some combinations. Effective combinations in vitro were further tested in a chronic, high-density murine infection model. Colistin and azithromycin demonstrated combinatorial effects with ceftazidime and ceftazidime/avibactam both in vitro and in vivo. Conversely, while tobramycin and tigecycline exhibited strong synergy in vitro, this effect was not observed in vivo. Our approach of using host-mimicking conditions and a sophisticated animal model to evaluate drug synergy against bacterial pathogens represents a promising approach. This methodology may offer insights into the prediction of combination therapy outcomes and the identification of potential treatment failures.
BACKGROUND: Pain management following mastectomy is a significant challenge often requiring opioids. Nonopioid pain management utilizing nerve blocks has been shown in other fields to reduce postoperative opioid use and may be effective for postoperative pain in mastectomy patients. The primary purpose of this study was to compare postoperative opioid use, measured in morphine milligram equivalents (MME), between mastectomy patients who underwent interpectoral nerve block (IPNB) and a historical control group. Secondary outcomes included length of stay (LOS) and postoperative pain scores.
METHODS: This is a single-center, retrospective cohort study. The charts of women who underwent mastectomy for cancer without immediate reconstruction from 10/2017-12/2019 were reviewed. Wilcoxon rank sum test was used for unadjusted analysis and multiple linear regression for adjusted analysis.
RESULTS: There were 105 patients included in this study, of which 37 (35%) underwent IPNB. In unadjusted analysis, median MME use was significantly lower in patients that received IPNB compared to the control group (IPNB = 5, controls = 17, p = 0.03). Patients that received IPNB had an observed reduction in LOS and postoperative pain, though these results failed to reach statistical significance. There were no IPNB-related complications.
CONCLUSIONS: IPNB may be an effective strategy to decrease postoperative opioid use in mastectomy patients. Larger, prospective studies are needed to further investigate the effectiveness of IPNB.
Described herein is a method of dyeing the hair. The method includes applying to the hair a hair color composition including one or more direct dye compounds and rinsing the hair with water. The one or more direct dye compounds each include a chromophore, one or two permanent cations, one to four incipient cations, and one or more hydrophobic moieties. The incipient cations are pendant to the core structure and are neutral. The one or more direct dye compounds enter the hair shaft after the hair color composition is applied to the hair. The hair color composition has a pH of from about 7 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6. The rinsing of the hair causes one or more of the one to four incipient cations to change from neutral to positively charged inside of the hair shaft.
