Assistive technologies for pain management in people with amputation: a literature review

Investigation of the impact of copper nanoparticles coated with ocimum bassilicum at chemoradiotherapy of colon carcinoma

Background

Colon carcinoma poses a significant health challenge globally, particularly in developed nations where sedentary lifestyles, poor dietary choices, and genetic factors play a crucial role in its prevalence. Chemotherapy, the primary treatment method, carries severe side effects that can jeopardize patients' lives. Herbal extracts such as Ocimum Basillicum extract have shown effectiveness against cancer cells. Additionally, nanoparticles can significantly enhance drug delivery efficacy in these scenarios.

Aim

This article aims to investigate the impact of copper nanoparticles coated with Ocimum Bassilicum at chemoradiotherapy of Colon Carcinoma to hopefully create new treatment options with fewer side effects for patients.

Methodology

CuO bio-NPs were produced by the addition of 15 mL of extract dropwise to 80 mL of a 5 mM Cu (OAc)2 aqueous solution, which was then refluxed for 2 h at 100 °C. The mixture gradually became darker brown in color as a result of the heating procedure. The production of CuO NPs and the hydrogen-donating activity of antioxidant phenols within the plant are signaled by surface plasmon resonance excitation, which is the cause of this. In the cell culture, LS174t colon cancer cells were treated with OB extract, CuNPs, and OB-coated CuNPs with and without different radiation levels in order to assess cell viability, through the MTT assay, and the pro-apoptotic BAX and anti-apoptotic BCL2 expressions, through qPCR assay.

Results

The results demonstrate a decrease in cell viability and the expression of BCL2 and an increase in the expression of BAX especially when treated with OB-coated CuNPs and even furthermore when paired with radiation therapy.

Conclusions

After doing the clinical trial studies, the recent nanoparticles can be used for the treatment of Colorectal carcinoma.

Pain, Balance-Confidence, Functional Mobility, and Reach Are Associated With Risk of Recurrent Falls Among Adults With Lower-Limb Amputation

Objective

The study evaluated whether pain intensity and extent, balance-confidence, functional mobility, and balance (eg, functional reach) are potential risk factors for recurrent falls among adults with a lower-limb amputation.

Design

Cross-sectional study.

Setting

Research laboratory.

Participants

Eighty-three adults with unilateral lower-limb amputation that occurred >1 year prior (26 transfemoral- and 57 transtibial-level amputation; 44.6% women; 51.8% traumatic cause of amputation; N=83).

Intervention

Not applicable.

Main Outcome Measures

Participants reported on the number of falls in the past year, as well as pain intensity in the low back, residual, and sound limbs. Balance-confidence (per the Activities-Specific Balance-Confidence Scale [ABC]), functional mobility (per the Prosthetic Limb Users Survey of Mobility ([PLUS-M]), and balance (per the Functional Reach and modified Four Square Step Tests) were obtained.

Results

After considering non-modifiable covariates, greater extent of pain, less balance-confidence, worse self-reported mobility, and reduced prosthetic-side reach were factors associated with recurrent fall risk. Adults reporting pain in the low back and both lower-limbs had 6.5 times the odds of reporting recurrent falls as compared with peers without pain. A 1-point increase in ABC score or PLUS-M T score, or 1-cm increase in prosthetic-side reaching distance, was associated with a 7.3%, 9.4%, and 7.1% decrease in odds of reporting recurrent falls in the past year, respectively.

Conclusions

Of the 83 adults, 36% reported recurrent falls in the past year. Presence of pain in the low back and both lower-limbs, less balance-confidence, worse PLUS-M score, and less prosthetic-side reaching distance were identified as modifiable factors associated with an increased odd of recurrent falls.

Study of Epidemiological Characteristics of Fatal Injuries Using Death Registry Data in Georgia

Objective

This study aimed to evaluate epidemiological aspects of fatal injuries in Georgia.

Methods

This was a retrospective, descriptive study that included all traumatic injury deaths in Georgia from January 1 to December 31, 2018. The National Center for Disease Control and Public Health of Georgia's Electronic Death Register database was utilized in this research.

Results

Of the study fatal injuries, 74% (n=1489) were males. 74% (n=1480) of all fatal injuries were caused by unintentional injuries. Road traffic accidents (25%, n=511) and falls (16%, n=322) were the primary causes of mortality. During the research year, the number of Years of life lost (YLL) was associated with injuries and was increased to 58172 for both sexes (rate per 1000 population: 15.6). Most of the years were lost in the age group of 25-29 years (7515.37). Road traffic deaths accounted for 30% (17613.50) of YLL.

Conclusion

Injuries are still a major public health problem in Georgia. In 2018, 2012 individuals died from injuries across the country. However, mortality and YLL rates of injury varied by age and cause of injury. To prevent injury-related mortality, it is crucial to conduct ongoing research on high-risk populations.

Landslide disasters in eastern Uganda: post-traumatic stress disorder and its correlates among survivors in Bududa district

BACKGROUND

Post-traumatic stress disorder is the commonly reported psychiatric morbidity among the survivors of natural disasters. However, its prevalence particularly in Bududa, Eastern Uganda is largely unknown.

AIMS AND OBJECTIVES

To assess the prevalence and correlates of post-traumatic stress disorder among Bududa landslide survivors.

METHODS

A community-based cross-sectional study was conducted on a sample of 587 participants. The study setting was the Bududa district, with a multistage sampling method. Pre-tested, administered interviewer PTSD Checklist-civilian version was used as screening tools between 4th and April 29th 2022. Data were analyzed using descriptive and binary logistic approaches at a 5% level of significance.

RESULTS

Of the study participants, 276 (46.8%) had PTSD symptoms. Among the respondents, 250 (42.6%) were in the age range of 40 and above, 396 (67.3%) were female, 284 (48.4%) had no formal education, and 333 (56.7%) were married. Results showed that male gender (AOR: 0.47; 95% CI 0.31-0.73; p = 0.001), widowhood (AOR: 0.44; 95% CI 0.21-0.94; p = 0.034), lack of counseling (AOR: 0.44; 95% CI 0.21-0.94; p = 0.001), and duration since the landslide (AOR: 0.35; 95% CI 0.23-0.52; p = 0.001) were associated with an increased likelihood of screening for PTSD in landslide survivors.

CONCLUSION

Landslides pose significant effects on the mental health of survivors. In the present study, the extent of PTSD among survivors is substantially high. male gender,, widowhood, lack of counselling, low social support, and duration since the landslide were significantly associated with PTSD. Effective screening and awareness programs among survivors should be strengthened for the prevention and treatment of psychiatric morbidity among the survivors of landslides.

Feedforward Control Combined with 4F Management on Postoperative Nursing Effects and Motor Function of Meniscus Sports Injuries: Based on a Prospective Case Analysis

Background

Because active functional training and management after knee cartilage sports injury is the key to treatment, care of patients after an operation with knee cartilage sports injury is critical.

Aims

To explore the effect of feedforward control combined with 4F management and after an operation nursing effect on patients with knee cartilage sports injury.

Materials and Methods

According to the random number table method, 100 patients with knee cartilage sports injury who were nursed in our hospital from June 2019 to June 2021 were selected as the research objects and divided into the control group and the instance of watching, noticing, or making a statement group with 50 cases in each group according to the different nursing order. Among them, the control group adopted 4F management combined with feedforward control nursing mode: all-weather, whole-process, whole-system, and all-around services for patients. On this basis, the instance of watching, noticing, or making a statement group cooperated with early healing/repairing training to compare fear and stress-related self-test of the two groups of patients after an operation. Knee function and quality of care are scored using tables.

Results

After nursing, the knee joint function score of the instance of watching, noticing, or making a statement group was higher than that of the control group, while the pain after the operation, sleep quality, fear, and stress self-rating scale scores were significantly lower than the control group (P < 0.05). The whole-process management, body position placement, risk evaluation, repairing training, all-weather service, whole-system management, and comprehensive service of the two groups of patients were very much improved. The nursing quality of watching, noticing, or making a statement group was significantly higher than the control group (P < 0.05).

Conclusion

Feedforward control combined with 4F management combined with early repairing training can effectively reduce the fear and stress after an operation pain and sleep quality of knee cartilage sports injury and help increase the recovery of knee combined function in a good way.

Antimicrobial Coating Efficacy for Prevention of Pseudomonas aeruginosa Biofilm Growth on ISS Water System Materials

Biofilms can lead to biofouling, microbially induced corrosion, physical impediment and eventual loss in function of water systems, and other engineered systems. The remoteness and closed environment of the International Space Station (ISS) make it vulnerable to unchecked biofilm growth; thus, biofilm mitigation strategies are crucial for current ISS operation and future long duration and deep-space crewed missions. In this study, a space flown bacterial strain of Pseudomonas aeruginosa (PA14) was used as a model organism for its ability to form biofilms. Additionally, a novel antimicrobial coating’s ability to reduce biofilm accumulation on stainless steel, Teflon, titanium, and Inconel (all used in the ISS water treatment and handling systems) was analyzed. Coated materials demonstrated reductions of P. aeruginosa biofilm across all materials when tested in a continuous flow system with tryptic soy broth medium. However, the coating lost efficacy in potato dextrose broth medium. These findings were corroborated via scanning electron microscopy. This study illustrates the fundamental importance of using multiple approaches to test antibiofilm strategies, as well as the specificity in which conditions such strategies can be implemented.

Psychiatric comorbidities among COVID-19 survivors in North India: A cross-sectional study

BACKGROUND

The coronavirus disease-19 (COVID-19) emerged from China and rapidly spread to many other countries all over the world. This study aimed to assess the prevalence of anxiety, depression, posttraumatic stress disorder, and obsessive-compulsive (OC) symptoms among COVID-19 survivors after their discharge from the COVID-19 treatment center.

MATERIALS AND METHODS

This was a cross-sectional, hospital-based study performed among 119 COVID-19 survivors. The Hospital Anxiety and Depression Scale (HADS) was used to measure anxiety and depression. Posttraumatic Stress Disorder (PTSD)-Checklist (PCL) and Brief OC Scale were used to measure PTSD and OC symptoms. Data were analyzed by descriptive and inferential statistics using the SPSS (IBM Corp. Released 2015 version 23.0).

RESULTS

The mean anxiety, depression, and PTSD scores were, 7.12 ± 0.68, 8.08 ± 0.22, and 19.78 ± 0.88, respectively. Based on cutoff scores, the prevalence of anxiety, depression, and PTSD among COVID-19 survivors was n = 53, 44.54%; n = 73, 61.34%; and n = 30, 25.21%, respectively. Older COVID-19 survivors (≥50 years) were more likely to show symptoms of depression and anxiety (P < 0.001) compared to younger ones. Furthermore, COVID-19 survivors who were ≥50 years of age experienced a greater level of PTSD compared to younger ones; similar trends were seen in those experiencing OC symptoms. In the present study, n = 98 (82.4%) were obsessed with fears of contamination and an equal number had compulsive handwashing.

CONCLUSION

Anxiety, depression, PTSD, and OC symptoms are common among the COVID-19 survivors and that underscores the need to diagnose and manage mental health morbidities among these survivors long after their recovery from COVID-19.

An Intrafascicular Neural Interface With Enhanced Interconnection for Recording of Peripheral Nerve Signals

For implantable devices, Parylene C (hereafter referred to as Parylene) has shown promising properties such as flexibility, biocompatibility, biostability, and good barrier properties. Parylene-based flexible interconnection cable (FIC) was previously developed to connect a flexible penetrating microelectrode array (FPMA) with a recording system. However, Parylene-based FIC was difficult to handle and prone to damage during the implantation surgery because of its low mechanical strength. To improve the mechanical properties of the FIC, we suggest a mechanically enhanced flexible interconnection cable (enhanced FIC) obtained using a combination of Parylene and polyimide. To investigate the long-term stability of the enhanced FIC, Parylene-only FIC, and enhanced FIC were tested and their mechanical properties were compared under an accelerated aging condition. During the course of six months of soaking, the maximum strength of the enhanced FIC remained twice as high as that of the Parylene-only FIC throughout the experiment, although the mechanical strength of both FICs decreased over time. To show the capability of the enhanced FIC in the context of nerve signal recording as a part of a neural interfacing device, it was assembled together with the FPMA and custom-made wireless recording electronics. We demonstrated the feasibility of the enhanced FIC in an in vivo application by recording acute nerve signals from canine sciatic nerves.
