Comparing the Effectiveness and Safety of Dexamethasone, Methylprednisolone and Betamethasone in Lumbar Transforaminal Epidural Steroid Injections.

BACKGROUND: Particulate steroids are thought to exert their effects for long durations at injection sites. However, these types of steroids carry higher risks when used in epidural steroid injections. Catastrophic spinal cord complications, including sudden-onset paraplegia, have been reported due to intravascular particulate steroid preparations that cause embolisms and occlusion of blood vessels, resulting in spinal cord infarctions. Clinicians, therefore, recommend nonparticulate steroids to mitigate these adverse events. To our knowledge, this is the first retrospective study that addresses the effectiveness and safety of methylprednisolone, dexamethasone, and betamethasone when used in transforaminal epidural steroid injections (TFESIs) for the treatment of lumbar radiculopathy. OBJECTIVES: The primary goal of this study was to compare the proportion of patients who received injections of particulate steroids and required zero repeat injections within 12 months of their initial injection to the proportion of patients who received injections of nonparticulate steroids and also required zero repeat injections, as well as to compare the number of patients in the particulate cohort who required one or more repeat injections within 12 months of their initial injection to the number of patients in the nonparticulate cohort who required the same. The secondary goal was to evaluate the proportion of patients ultimately requiring surgery. STUDY DESIGN: This is a single-center, IRB-approved, retrospective study evaluating the safety and effectiveness of nonparticulate as compared to particulate steroid medications when used in TFESIs as minimally invasive treatments for chronic lumbar radiculopathy. SETTING: This study captured data (n = 1717) over a 4-year time frame (01/15/2018 to 01/15/2022). METHODS: The following data were collected from each patient's chart: age, gender, BMI, race, date of initial injection, number of repeat injections at the same lumbosacral level and on the same side within 12 months of the initial injection, and lumbar surgery date (if applicable). Inclusion criteria included: 1) having chronic low back pain of radicular etiology; 2) being at least 18 years old; 3) having experienced the failure of conservative therapy after 12 weeks (including physical therapy and/or medications); 4) having positive physical exam findings supporting nerve impingement (straight leg raise, slump test); and 5) showing lumbar MRI evidence of nerve impingement from disc herniation. Exclusion criteria included: 1) having received prior lumbar surgery at any level (L1-S1); 2) having been given prior TFESIs fewer than 6 months prior to initial injection; 3) having contracted a systemic infection at the proposed injection site; 4) undergoing active cancer treatment; and 5) having gotten any other spine injections. RESULTS: A significantly greater proportion of patients in the nonparticulate steroid cohort received 0 repeat injections (87.5% vs 71.4%, P < 0.001). The particulate steroid cohort demonstrated a significantly greater proportion of patients who received repeat injections within 12 months after the initial injections (12.5% vs 29.6%, P < 0.001). There were no significant differences among patients requiring surgery between the 2 cohorts. Other outcome measures included the identification of risk factors significantly associated with repeat injections. There was a statistically significant weak positive correlation between age and repeat injections (Pearson corr = 0.102; P < 0.001) and a weak negative correlation between ethnicity/race and repeat injections (point-biserial corr = -0.093; P < 0.001).  No adverse events were reported. LIMITATIONS: Not all clinicians included in this study used each of the 3 steroid types, and all clinicians used either particulate or nonparticulate steroids exclusively. CONCLUSIONS: Our study demonstrates that the clinical outcomes associated with TFESIs of nonparticulate steroids are superior to those associated with TFESIs of particulate steroids when either variety of medication is used to treat lumbar radiculopathy. This is the first study to include a clinically useful predictive model using information on laterality, age, and steroid type.

Non-inferiority study assessing the utility of postcervical and lumbar radiofrequency ablation steroid use.

INTRODUCTION: Many physicians administer steroids after radiofrequency ablation (RFA) to mitigate postprocedural inflammation and decrease postprocedural pain. However, robust evidence supporting the benefits of steroids after RFA is lacking and steroids have risks. METHODS: This study was a single-center, prospective, observational study designed to assess whether RFA alone is inferior to RFA with steroids for postprocedure pain. Eligible patients were at least 18 years of age and scheduled to undergo cervical or lumbar RFA. The primary outcome measure was the average pain score on the numeric rating scale (NRS) 7 days after the RFA. The secondary outcome measures included anxiety, depression and physical function, measured via the Patient-Reported Outcomes Measurement Information System short forms. All outcome measures were completed prior to the procedure and at 7 and 60 days postprocedure. RESULTS: Out of the 365 participants who completed baseline assessments, 175 received steroids and 190 did not receive steroids. The pain intensity at 7 days postprocedure was similar between the steroid and non-steroid groups (mean difference (steroid-non-steroid): -0.23). The 95% CI of the estimate (-0.76 to 0.30) was within the prespecified non-inferiority margin of 1.5 NRS points. Similar results were obtained for pain at 60 days (mean difference: 0.09; 95% CI -0.48 to 0.65). No significant differences between groups were observed for anxiety, depression or physical function at either 7 or 60 days. CONCLUSION: This study suggests that the addition of steroids to the RFA procedure does not provide added benefits and is therefore not worth the additional risks that they pose.

Degree of fear of needles and preferred allergy immunotherapy treatment among children with allergic rhinitis: caregiver survey results.

Introduction: A child's fear of needles may impact the preferred route of allergy immunotherapy (AIT) when choosing between subcutaneous immunotherapy (allergy shots) or sublingual immunotherapy (SLIT). A survey was conducted to understand caregiver health-seeking behavior for children with allergic rhinitis with or without conjunctivitis (AR/C) and explore if fear of needles impacted AIT decisions. Methods: Caregivers of children ages 5-17 years with AR/C were recruited from the Dynata US research panel to participate in an online survey from May-June 2023. The survey received institutional review board exemption status. SLIT-tablets were described as "under-the-tongue tablets". Results: About a third (34%) of surveyed caregivers (n = 437) reported their child had a severe fear of needles and 47% reported moderate fear. Of surveyed caregivers, 53% and 43% reported they had discussed allergy shots and SLIT-tablets, respectively, with their child's physician. SLIT-tablets were preferred by 84% of caregivers; 6% preferred injections and 10% had no preference. Caregivers of children with a severe fear of needles had the highest preference for SLIT-tablets (95%) vs. injections (2%); 85% and 60% of caregivers of children with moderate and low fear, respectively, preferred SLIT-tablets. Among caregivers of children with a severe fear of needles, a higher percentage agreed that their child would welcome taking SLIT-tablets than that their child would accept taking an ongoing series of allergy shots (93% vs. 43%, respectively). Conclusions: Most caregivers preferred SLIT-tablets over allergy shots for their child with AR/C. Preference for SLIT-tablets corresponded with the child's degree of fear of needles. Fear of needles should be included in AIT shared decision-making conversations.

Comparing CIDR with progesterone injections and eCG with human recombinant FSH for synchronizing estrous cycle in ewes.

Background: It is desirable in estrus synchronization in sheep to avoid intravaginal devices and to shorten the program from 14 to 6 days. Moreover, replacement of eCG with safe, cheap, and efficient gonadotropin is in worldwide demand. Aims: This study investigates the possibility of replacing eCG with human recombinant FSH (hrFSH) and CIDR with progesterone injections for estrous synchronization in ewes. Methods: Assaf and Lacaune ewes (n=170) were divided into two groups and synchronized with either progesterone injections for 6 days or CIDR for 14 days. Ewes assigned in the injection group, received progesterone (37.5 mg; SC) and GnRH analogue (7.5 µg Alarelin acetate; IM) on day 0 of the experiment. On days 3 and 6, ewes received 25 and 12.5 mg progesterone (SC), respectively. On day 6, ewes in both groups received prostaglandin F2α (250 µg Cloprostenol; IM), and were divided into two subgroups to receive either hrFSH (75 IU Follitropin alfa; SC) or eCG (400 IU; IM). On day 7, fertile rams were introduced to ewes for 21 days. Data were analyzed using GLM and Glimmix. Results: There was no difference in the respective lambing rates, prolificacy, and fecundity between CIDR (71.1, 1.63, and 1.16%) and injections (66.7, 1.55, and 1.03%); between eCG (71.4, 1.60, and 1.14%), and hrFSH (66.3, 1.58, and 1.05%, P>0.05). Conclusion: In conclusion, 6-day progesterone injection-based protocol produced similar results to 14-day CIDR program and hrFSH could be an effective alternative for eCG during estrus synchronization in ewes.

Two-year outcomes of intravitreal aflibercept injection for neovascular age-related macular degeneration with 'observe before treat-and-extend' method.

Purpose: To evaluate two-year outcomes of intravitreal aflibercept injection for neovascular age-related macular degeneration (nAMD) treated with 'observe before treat-and-extend' (O-TAE) strategy in the real-world setting. Methods: This retrospective study included treatment-naïve nAMD patients treated with aflibercept using O-TAE regimen and followed up for more than 2 years. Patients were observed bimonthly to check recurrence after 3 monthly loading injections. In case of recurrence, treatment was resumed using the treat-and-extend (TAE) regimen starting from the 4th injection. In case of non-recurrence, observation was continued. Best-corrected visual acuity (BCVA), central macular thickness (CMT), number of injections, TAE intervals, and proportion of recurrence after dry-up following 3 loadings were analyzed. Results: 38 eyes of 34 patients were included. Follow-up period was 37.0 ± 11.0 months. BCVA by logMAR improved from 0.33 ± 0.29 at baseline to 0.24 ± 0.23 in the 1st year (p = 0.01), and 0.25 ± 0.22 in the 2nd year (p = 0.054). CMT decreased significantly from 357.4 ± 74.5 at baseline to 269.6 ± 48.1 in the 1st year (p < 0.001), and 279.1 ± 54.6 in the 2nd year (p < 0.001). Numbers of injections were 5.1 ± 1.7 in the first year and 3.8 ± 2.4 in the second year. The percentage of eyes with a TAE interval of ≥12 weeks was 37.0% in the first year and 34.4% in the second year. Of the 36 eyes that dried up after 3 loadings, 28 eyes (78%) recurred, and the average period of recurrence was 6.5 months. The remaining 8 eyes (22%) had no recurrence during the mean follow-up period of 29.7 months. Conclusion: This study showed that the newly suggested O-TAE strategy can reduce the treatment burden significantly reducing the number of injections while improving BCVA and CMT in the first and second year.

This report describes the case of a patient who presented to the Emergency Department (ED) with a one-week history of difficulty in breathing, generalized weakness, dysphagia, and difficulty in walking. She had self-administered 100 units of onabotulinumtoxin A (BoNT-A) by injection into her face two weeks prior for cosmetic purposes. This case study highlights the rare but potential complication of systemic botulism.

Association of continuous subcutaneous insulin therapy and diabetic retinopathy in type 1 diabetes: A national cohort study.

AIM: This study aimed to investigate the short-and long-term effect on diabetic retinopathy (DR) in individuals with type 1 diabetes treated with continuous subcutaneous insulin injections (CSII) compared to those using multiple daily injections (MDI). METHODS: We conducted a register-based matched cohort study utilizing data from the Danish Registry of Diabetic Retinopathy as well as several other national Danish health registers. Our cohort consisted of all individuals with type 1 diabetes who attended the Danish screening program for DR from 2013 to 2022. We included individuals registered with CSII treatment, and compared them to individuals using MDI, matched by age, sex, and DR level. Cox regression analysis was performed to evaluate the outcomes. RESULTS: The study included 674 individuals treated with CSII and 2006 matched MDI users. In our cohort 53.4 % were female and median age was 36 (IQR 27-47). Average follow-up risk-time was 4.8 years. There was no difference in the risk of DR worsening between the CSII group and MDI group (HR 1.05 [95%CI 0.91; 1.22], p = 0.49). However, an increased risk of focal photocoagulation was observed in the CSII group (HR 2.40 [95%CI 1.11; 5.19], p = 0.03). CONCLUSIONS: Our findings indicate that CSII treatment does not confer a significant difference in the overall short- and long-term risk of DR worsening or ocular intervention compared to MDI treatment. These results provide insights into the DR outcomes of CSII treatment in individuals with type 1 diabetes.

Ultrasound-guided arthrocentesis and intra-articular injection of the hip and shoulder joints in the dog.

OBJECTIVE: To provide a video tutorial on ultrasound-guided arthrocentesis and injection of the canine hip and shoulder joints. ANIMALS: Dogs undergoing arthrocentesis or intra-articular injection for diagnostic or therapeutic purposes. METHODS: The target joint is visualized in long axis with a 70% isopropyl alcohol medium and linear array probe with a frequency range of 2 to 14 MHz and footprint of 50 mm after clipping a window and preparing the region sterilely. The needle is inserted, bevel up, in long axis with the probe angled at the appropriate trajectory to enter the joint space. The needle is advanced until the tip is visualized entering the joint. Aspiration to obtain synovial fluid can further confirm needle placement or provide diagnostic sampling prior to injection. The aspirate syringe is exchanged for that containing the therapeutic agent, and injectate can then be visualized entering and/or expanding the joint upon injection. RESULTS: Ultrasound-guided arthrocentesis will help identify deep appendicular joints (hip and shoulder), avoid surrounding vasculature, confirm needle placement, and target joint fluid pocketing. Needle guidance into a joint can reduce iatrogenic tissue damage from inappropriate needle placement and/or by minimizing attempts. CLINICAL RELEVANCE: For arthrocentesis, ultrasound guidance can maximize joint fluid volume acquisition for diagnostic purposes (cytology, culture, and fluid analysis) while also avoiding blood contamination. For joint injections, ultrasound will help ensure real-time intra-articular delivery of the injectate (regardless of attaining synovial fluid feedback) to maximize the therapeutic effect. For either purpose, iatrogenic tissue damage and procedure time are minimized.

XueBiJing injection improves the symptoms of sepsis-induced acute lung injury by mitigating oxidative stress and ferroptosis.

ETHNOPHARMACOLOGICAL RELEVANCE: XBJ injection is approved by the China Food and Drug Administration for the adjunctive treatment of sepsis, and it is derived from the traditional Chinese medicine (TCM) prescription XuefuZhuyu Decoction. It consists of five Chinese herbal extracts: Carthamus tinctorius, Paeonia lactiflora, Salvia miltiorrhiza, Conioselinum anthriscoides 'Chuanxiong' and Angelica sinensis. AIM OF THE STUDY: The purpose of this study was to explore the relationship between ferroptosis and acute septic lung injury, and to evaluate the improvement effect of XBJ injection on acute lung injury in sepsis. MATERIALS AND METHODS: Acute lung injury was induced in rats by cecum ligation and puncture, and these rats were treated with XBJ injection. Oxidative stress and inflammation levels were assessed in serum and lung tissue, and tissue samples were collected for histological and protein analyses. To illustrate the mechanism of the improvement effect of XBJ on acute lung injury in sepsis, serum lipidomics was carried out to investigate whether XBJ prevents oxidative stress-induced lipid metabolism disorders. Furthermore, protein expression of ferroptosis-related genes was also examined. RESULTS: XBJ was shown to be effective in alleviating sepsis-induced ALI. XBJ also improves sepsis-induced acute lung injury by reducing lipid peroxidation and inflammation and modulating ferroptosis pathways. Specifically, compared with the sham group, XBJ downregulated the levels of Fe2+, MDA and GSSG, and reversed the decrease in the levels of GSH and GSH/GSSH in lung tissue. Metabolic pathways such as glycerophospholipid metabolism, phospholipid metabolism, and lipid metabolism associated with ferroptosis were obtained by lipidomic analysis of differential lipid metabolite enrichment, suggesting that ferroptosis occurs in septic rats, and that XBJ inhibits ferroptosis and thereby improves sepsis-induced ALI. Furthermore, XBJ optimises iron metabolism and lipid oxide metabolism by regulating the expression of a series of proteins that are closely related to ferroptosis, such as GPX4, ACSL4, x-CT, and FTH1. CONCLUSIONS: Our findings, initially, indicated that XBJ ameliorates sepsis-induced ALI by reducing oxidative stress and ferroptosis, revealing a previously unrecognised mechanism by which XBJ ameliorates sepsis-induced ALI.

Impact of the Nationwide Avastin Ban at a Tertiary Eye Care Hospital in Pakistan.

OBJECTIVE:  To report the impact of a 10-week-long nationwide ban on intra-vitreal bevacizumab (IVB) injection (Avastin®) at a tertiary care hospital in Pakistan. METHODS: This was a single-center, retrospective, cohort study. Patients scheduled for IVB injections from October 25, 2023 to October 29, 2023 who arrived in OPD between November 28, 2023 and December 15, 2023 for their assessment were included in this study. RESULTS: Among the identified 412 patients, only 103 met the inclusion criteria. The mean age was 59.35 ± 9.5 (mean ± SD). About 60.2% were male (n = 62). Diabetic macular edema (DME) was the most common indication (n = 71, 68.9%). The mean total duration of treatment delay was 81.67 ± 17.15 days. While the delay due to the Avastin® ban was 67.47 ± 4.8 days. Eyes that had not received any prior injections were 46 (44.7%) while others had received at least 1 (n = 43, 41.7%) or 2 injections (n = 14, 13.6%) before. Mean central macular thickness (CMT) before and after treatment delay was 362.7 ± 113.4 µm and 398.38 ± 124 µm (p < 0.05), respectively. Among 20 patients with vitreous hemorrhage (VH), 14 patients showed marked improvement (70%), 5 showed no change in severity (20%) and 1 (5%) had further worsening. CMT difference was strongly correlated with the total duration of treatment delay (p < 0.01) and with the number of injections (p < 0.01). CONCLUSION: The nationwide ban on Avastin® heightened the severity of disease in the patients highlighting the delicate balance between safety precautions and timely access to essential medical interventions.

Identification and quantification of micro-nano-plastics in polypropylene-bottled injections.

Micro-nano-plastic (MNP) particles (p) in the environment can enter the human body and pose a potential threat to human health. However, it is unknown whether these substances are present in polypropylene (PP) plastic-bottled injections, which are used as high-frequency intravenous infusions to treat diseases. Therefore, the objective of this study was to identify and quantify insoluble MNP particles in 16 batches of injectable formulations within the validity period. Primarily, ethylene-propylene copolymer or P(E-P) micro-plastic (MP) particles (2-10 µm, 216 p/mL) were identified by micro-Raman spectroscopy, and nano-particles (<50 nm, 2.1 × 104 p/mL) similar to PP containing only carbon were detected by scanning electron microscopy-energy-dispersive X-ray spectroscopy (photoelectron). Furthermore, P(E-P) MP particles (1 × 103 to 1 × 105 ng/L) from the injections were enriched on the GF-B filter, and PP or P(E-P) nano-plastic (NP) particles (1 × 103 to 4 × 104 ng/L) enriched on the alumina film were detected by pyrolysis-gas chromatography/mass spectrometry. Finally, the total insoluble particles in injections were 6 × 104 to 1 × 107 p/mL (0.02-100 µm). Our findings are the first to identify and quantify MNPs in PP-bottled injections. Considering that they can enter the blood circulation, so whether cause disease remains to be investigated.

Refining Insulin on Board with netIOB for Automated Insulin Delivery.

Automated insulin delivery (AID) systems enhance glucose management by lowering mean glucose level, reducing hyperglycemia, and minimizing hypoglycemia. One feature of most AID systems is that they allow the user to view "insulin on board" (IOB) to help confirm a recent bolus and limit insulin stacking. This metric, along with viewing glucose concentrations from a continuous glucose monitoring system, helps the user understand bolus insulin action and the future "threat" of hypoglycemia. However, the current presentation of IOB in AID systems can be misleading, as it does not reflect true insulin action or automatic, dynamic insulin adjustments. This commentary examines the evolution of IOB from a bolus-specific metric to its contemporary use in AID systems, highlighting its limitations in capturing real-time insulin modulation during varying physiological states.

Approved treatments for neovascular age-related macular degeneration: current safety and future directions.

INTRODUCTION: Age-related macular degeneration (AMD) is a progressive retinal degenerative disease that is implicated as one of the leading causes of visual impairment in the elderly population. Vascular endothelial growth factor (VEGF) has been identified as the main driver of AMD, and various therapeutics have revolutionized the treatment and management of neovascular AMD (nAMD) with favorable visual and anatomical outcomes. AREAS COVERED: Physicians have a variety of approved therapeutics in their arsenal for patients with varying disease progression and patient-specific needs, with the ultimate goal of achieving optimal visual and anatomic outcomes. The literature search was conducted using PubMed, Google Scholar, and sources from companies' websites, allowing us to locate findings recently presented at conferences. EXPERT OPINION: Scientific advancements in the field have led to newly approved therapeutics and devices, such as the port-delivery system with ranibizumab (PDS), and further investigation is ongoing in the realm of gene therapy for retinal diseases. In addition to efficacy and durability, newer agents must have comparable safety profiles to older agents in order to be used broadly. These options introduce a level of complexity in nAMD treatment; however, physicians to personalize treatment to improve vision in nAMD patients and reduce treatment burden overall.

Comparative analysis of contrast distribution in cervical epidural steroid injections utilizing a modified paramedian interlaminar approach with varied needle tip positions: A randomized controlled trial.

BACKGROUND: Recent advancements in cervical interlaminar epidural steroid injections have given rise to the modified paramedian interlaminar (mPIL) approach. The objective of this study was to perform an analysis of the contrast spread pattern within the cervical epidural space, taking into account different needle tip positions in the mPIL approach. METHODS: A total of 48 patients were included in the study and randomly assigned to either the medial or lateral group based on the needle tip's position in the anterior-posterior view. The primary outcome measured was the contrast flow under fluoroscopic visualization. As a secondary outcome, we analyzed the location of the needle tip position in both lateral and contralateral oblique views. Clinical effectiveness was assessed by measuring pain intensity and functional disability post-procedure. RESULTS: Significant disparities were noted in the ventral distribution of contrast between the medial and lateral groups. In the lateral images, needle tips in the lateral group were positioned more ventrally compared to those in the medial group. Both groups exhibited statistically significant improvements in neck and radicular pain, as well as functional status, 4 weeks after treatment, with no significant differences between them. CONCLUSIONS: Our results suggest that the ventral dispersion of contrast material during cervical interlaminar epidural steroid injections using the mPIL approach may vary depending on the needle tip location.

Intra-arterial PSMA injection using hepatic arterial infusion pump in intrahepatic cholangiocarcinoma: a proof-of-concept study.

Prostate-specific membrane antigen (PSMA) targeted tracers show increased uptake in several malignancies, indicating a potential for peptide radioligand therapy. Intra-arterial injection of radiotracers can increase the therapeutic window. This study aimed to evaluate the feasibility of intra-arterial injection of [68Ga]Ga-PSMA-11 for intrahepatic cholangiocarcinoma and compare tracer uptake after intrahepatic arterial injection and intravenous injection. Three patients with intrahepatic cholangiocarcinoma received [68Ga]Ga-PSMA-11 through a hepatic arterial infusion pump, followed by positron emission tomography/computed tomography (PET/CT). Two-three days later, patients underwent PET/CT after intravenous [68Ga]Ga-PSMA-11 injection. All tumours showed higher uptake on the intra-arterial scan compared with the intravenous scan: the intra-arterial / intravenous standardised uptake value normalised by lean body mass ratios were 1.40, 1.46, and 1.54. Local intra-arterial PSMA injection is possible in patients with intrahepatic cholangiocarcinoma. Local injection increases tumour-to-normal tissue ratios, increasing the therapeutic window for theranostic applications. RELEVANCE STATEMENT: Intra-arterial Prostate specific membrane antigen (PSMA) injection increases the therapeutic window for potential theranostic application in intrahepatic cholangiocarcinoma. KEY POINTS: Three patients with intrahepatic cholangiocarcinoma underwent PET/CT after intra-arterial and intravenous injection of [68Ga]Ga-PSMA-11. Intra-arterial injection showed higher uptake than intravenous injection. PSMA-targeted imaging could be valuable for a subset of intrahepatic cholangiocarcinoma patients.

Transcutaneous oxygen tension-guided hyperbaric oxygen therapy for preventing skin necrosis after hyaluronic acid filler injections.

Introduction: Hyaluronic acid (HA) fillers, popular for facial cosmetic enhancements, pose risks of vascular complications like skin necrosis due to arterial blockage, necessitating effective treatments such as hyperbaric oxygen therapy (HBOT). Methodology: This study presents a series of cases where measurements of transcutaneous oxygen pressure (TcPO2) informed the application of HBOT for skin necrosis induced by HA. Clinical presentation and outcomes: In cases 1 and 3, following the injection of HA, potential skin necrosis was observed. In addition to standard treatment, TcPO2 revealed values below 40 mmHg, indicating tissue hypoxia. Treatment with HBOT increased TcPO2 levels to above 200 mmHg, suggesting that HBOT could correct the hypoxia. Monitoring TcPO2 levels also aided in determining the optimal time to discontinue HBOT. In cases 2 and 4, patients received standard treatment, resulting in TcPO2 levels above 40 mmHg, indicating adequate tissue oxygenation, and no additional HBOT was administered. All four patients mentioned above showed good clinical recovery. Conclusion: This study investigates the application of TcPO2 measurement technology in aiding decisions on whether to utilize HBOT in the treatment of complications arising from HA fillers, as well as in optimizing HBOT protocols.

Comparative effects of insulin pump and injection on gestational diabetes mellitus pregnancy outcomes and serum biomarkers.

BACKGROUND: Insulin injection is the basic daily drug treatment for diabetic patients. AIM: To evaluate the comparative impacts of continuous subcutaneous insulin infusion (CSII). METHODS: Based on the treatment modality received, the patients were allocated into two cohorts: The CSII group and the multiple daily injections (MDI) group, with each cohort comprising 210 patients. Comparative assessments were made regarding serum levels of serum-secreted frizzled-related protein 5, homocysteine, and C1q/TNF-related protein 9. Furthermore, outcomes such as fasting plasma glucose, 2-hour postprandial glucose levels, pain assessment scores, and the incidence of complications were evaluated post-treatment. RESULTS: The CSII group displayed notably lower fasting plasma glucose and 2-h postprandial glucose levels in comparison to the MDI group (P < 0.05). Subsequent analysis post-treatment unveiled a significantly higher percentage of patients reporting no pain in the CSII group (60.00%) in contrast to the MDI group (36.19%) (P < 0.05). Additionally, the CSII group exhibited a markedly reduced occurrence of fetal distress and premature rupture of membranes compared to the MDI group (P < 0.05). However, there were no significant variances observed in other pregnancy outcomes between the two groups (P > 0.05). A statistical analysis revealed a significant difference in the incidence of complications between the groups (χ 2 = 11.631, P = 0.001). CONCLUSION: The utilization of CSII via an insulin pump, as opposed to MDI, can significantly enhance the management of insulin administration in patients with GDM by diversifying the sites of insulin delivery. This approach not only promotes optimal glycemic control but also regulates metabolic factors linked to blood sugar, reducing the likelihood of adverse pregnancy outcomes and complications. The clinical relevance and importance of CSII in GDM management highlight its wide-ranging clinical usefulness.

Lack of Clinical Evidence Regarding the Guidelines for Vitamin B12 Deficiency: An Analysis From Literature and Recommendations From Clinical Practice.

BACKGROUND: Vitamin B12 deficiency is a critical medical condition that, if left untreated, can lead to severe symptoms and potentially serious and life-threatening complications. Clinical guidelines are designed to provide a standardized approach to diagnosis and treatment, aiming for consistency and effectiveness. However, it is well-established that not all patients fit into general guidelines. OBJECTIVE: To investigate the clinical relevance of the submitted research to support these protocols for diagnosing and treating a B12 deficiency. APPROACH: Conducting a literature review of the references focused and used on diagnosing and treating vitamin B12 deficiency in adults and children. RESULTS: No robust clinical trial nor RCT has been found to back up the current protocols. The research used is primarily based on assumptions rather than solid clinical evidence. CONCLUSION: Existing guidelines for vitamin B12 deficiency need to be significantly revised and improved through clinical research, clinical experience by experts in the field with input from patient groups worldwide.

Plain language titleAnalyzing the Lack of Research on Vitamin B12 Deficiency Guidelines: Insights from Studies and Clinical AdvicePlain language summaryThis study dives into Vitamin B12 deficiency, stressing its serious health impacts and potential life-threatening complications when not treated. The study aims to investigate the scientific articles supporting these guidelines and their clinical relevance, conducting an in-depth analysis of literature references. The manuscript investigates and criticizes current guidelines for B12 deficiency, pointing out 4 key issues reported by patients and clinicians worldwide. The results are grouped into 4 sections: Maintenance Dose Protocol: The study questions the adequacy of maintenance doses every few months, highlighting a lack of clinical evidence and challenging the idea of sufficient liver stores. Oral Supplementation Protocol: The effectiveness of oral supplements is questioned due to inconclusive trials, focusing on raising blood values rather than assessing actual clinical outcomes. Diagnosing B12 Deficiency in Children: Guidelines neglect B12 deficiency in children despite significant differences in B12 levels between adults and healthy kids, potentially leading to underdiagnosis and unnecessary suffering. Delay in Diagnosis and Treatment: Factors like a lack of awareness and diverse symptoms contribute to delays, emphasizing the ongoing challenge of standardizing B12 assays. In the discussion, the manuscript argues that awareness of guidelines is low, and evidence-based guidelines may lack practical relevance. It suggests a significant revision of guidelines based on robust clinical evidence, advocating for personalized treatment, patient monitoring tools, controlled trials, and age-related healthy levels. Recognizing diverse patient needs and implementing individualized therapies are crucial for improving care for those with vitamin B12 deficiency, emphasizing the importance of early recognition and intervention.

Endophthalmitis following intravitreal injections administered by junior medical officers in rural Western Australia.

BACKGROUND: Patients in rural Australia have limited access to intravitreal treatments due to a maldistribution of the ophthalmology workforce. To improve access, a novel outreach service model was implemented whereby junior medical staff administered intravitreal injections under a supervising ophthalmology consultant. This model involves outreach visits in hospitals, mobile clinics and a remote hub with intravitreal injections administered by junior doctors overseen by an ophthalmologist. The article explores the safety of this approach with respect to the rate of post-injection endophthalmitis. METHODS: A retrospective audit was conducted by the Lions Outback Vision outreach ophthalmology service from 2017 to mid-2023. The number of injections, locations, diagnoses, intravitreal agents used, designation of administering doctor and cases of endophthalmitis were reviewed. RESULTS: A 12 632 intravitreal injections were administered across 32 locations throughout rural Western Australia in the 6.5-year period. Three cases of endophthalmitis occurred representing a rate of 0.0237%. CONCLUSION: The rate of endophthalmitis in the outreach service is comparable to other centres. The outreach model with supervising ophthalmology consultant support in person or via telehealth and administration of injections by junior medical staff has improved access for underserved or marginalised populations.
