The acute effects of variations in the flour composition of crackers on the glycemic index and glycemic responses in healthy adults

BACKGROUND/OBJECTIVES

This study assessed the glycemic index (GI) and glycemic load (GL) of three crackers formulated with different flours: a control cracker (CC) made with conventional flour, one with 30% whole wheat flour substitution (WWC), and another with 30% sunflower seed flour substitution (SFC). This study aimed to explore the impact of these substitutions, which vary in protein and fiber content, on the glycemic responses compared to a reference glucose drink.

SUBJECTS/METHODS

In a randomized controlled, crossover design, 11 healthy participants (mean age 23.5 ± 1 years; 7 women; BMI 23 ± 1 kg/m2), consumed cracker meals (CC, WWC, and SFC) each providing 50 g of available carbohydrates, and a 50 g glucose reference in separate sessions.

RESULTS

The SFC crackers provided low GI and GL values (GI: 53 on the glucose scale, GL: 6 per serving), whereas the WWC and CC crackers provided high GI (GI: 77 and 90 on the glucose scale, respectively) and medium GL values (11 and 12 per serving, respectively). Compared with the glucose reference and CC crackers, only SFC induced lower postprandial glucose concentrations, lower glucose excursions, and lower peak glucose values. All crackers were rated as enjoyable and associated with increased satiety.

CONCLUSIONS

SFC moderated postprandial glycemic responses compared to CC and the reference (D-glucose), but not WWC. These effects may be attributed to the soluble fibers and protein content of the SFC. These findings suggest potential benefits for body weight management and glycemic control, warranting further investigation of the role of flour substitutions in healthy snack options.

Virtual rehabilitation for patients with osteoporosis or other musculoskeletal disorders: a systematic review

This study aims to identify effective ways to design virtual rehabilitation to obtain physical improvement (e.g. balance and gait) and support engagement (i.e. motivation) for people with osteoporosis or other musculoskeletal disorders. Osteoporosis is a systemic skeletal disorder and is among the most prevalent diseases globally, affecting 0.5 billion adults. Despite the fact that the number of people with osteoporosis is similar to, or greater than those diagnosed with cardiovascular disease and dementia, osteoporosis does not receive the same recognition. Worldwide, osteoporosis causes 8.9 million fractures annually; it is associated with substantial pain, suffering, disability and increased mortality. The importance of physical therapy as a rehabilitation strategy to avoid osteoporosis fracture cannot be over-emphasised. However, the main rehabilitation challenges relate to engagement and participation. The use of virtual rehabilitation to address such challenges in the delivery of physical improvement is gaining in popularity. As there currently is a paucity of literature applying virtual rehabilitation to patients with osteoporosis, the authors broadened the search parameters to include articles relating to the virtual rehabilitation of other skeletal disorders (e.g. Ankylosing spondylitis, spinal cord injury, motor rehabilitation, etc.). This systematic review initially identified 130 titles, from which 23 articles (involving 539 participants) met all eligibility and selection criteria. Four groups of devices supporting virtual rehabilitation were identified: a head-mounted display, a balance board, a camera and more specific devices. Each device supported physical improvement (i.e. balance, muscle strength and gait) post-training. This review has shown that: (a) each device allowed improvement with different degrees of immersion, (b) the technology choice is dependent on the care need and (c) virtual rehabilitation can be equivalent to and enhance conventional therapy and potentially increase the patient's engagement with physical therapy.

QTc Shortening on Electrocardiogram With Amitriptyline May Indicate No Effect on Pain Relief in Burning Mouth Syndrome

OBJECTIVE

Burning mouth syndrome (BMS) is an intractable chronic pain disorder characterized by a burning sensation without organic abnormalities in the oral mucosa. Amitriptyline may be effective for BMS or, conversely, may exacerbate pain. QTc is necessary for monitoring psychotropic adverse effects, but it is not known if it is a predictor of efficacy for BMS. We investigated the efficacy of amitriptyline in BMS and its effect on QTc.

METHODS

Visual analog scale and electrocardiogram were examined before and 1 month after treatment in 51 consecutive patients diagnosed with BMS according to the International Classification of Headache Disorders, Third Edition (ICHD-3), criteria and treated with amitriptyline.

RESULTS

There were 26 amitriptyline responders and 25 nonresponders, with no differences in age, sex, and amitriptyline dosage. Amitriptyline responders showed little change in QTc, whereas nonresponders showed a trend toward significantly shorter QTc. Changes in visual analog scale correlated statistically significantly with changes in QTc (Spearman rank correlation coefficient: 0384; P = 0.0054). The degree of pain tended to worsen with QTc shortening.

CONCLUSION

Amitriptyline provides analgesia in about half of BMS patients, but some BMS patients have worse pain with amitriptyline. Not only do changes in the QTc detect amitriptyline adverse effects with prolongation, but also, conversely, its shortening predicts amitriptyline ineffectiveness.

Shockwave therapy and fibromyalgia and its effect on pain, blood markers, imaging, and participant experience - a multidisciplinary randomized controlled trial

BACKGROUND

Patients with fibromyalgia experience chronic, widespread pain. It remains a misunderstood disorder with multimodal treatments providing mixed results.

OBJECTIVES

To examine the effects of radial shockwave therapy (RSWT) compared to placebo on pain, pain catastrophizing, psychological indices, blood markers, and neuroimaging. Study-related experiences were also explored qualitatively.

METHODS

Quantitative sensory testing (QST), Visual Analog Scale (VAS), Beighton Scoring Screen (BSS), Pain Catastrophizing Scale (PCS), blood biomarker (Interleukin (IL)-6 and IL-10), and brain fMRI were measured pre- and post-treatment along with a post-treatment survey. The RSWT group received five treatments (one week apart over five-week period) to the three most painful areas (500 shocks at 1.5 bar and 15 Hz, then 1000 shocks at 2 bar and 8 Hz, and finally 500 shocks at 1.5 bar and 15 Hz) versus sham treatment for the placebo group.

RESULTS

There were no statistically significant differences in the BSS for hypermobility (p = .21; d = .74), PCS (p = .70; d = .22), VAS (p = .17-.61; d = .20-.83) scores, QST for skin temperature and stimuli (p = .14-.65; d = .25-.88), and for the pressure pain threshold (p = .71-.93; d = .05-.21). The VAS scores had clinically significant changes (MCID greater than 13.90) with improved pain scores in the RSWT group. Neuroimaging scans revealed no cortical thickness changes. Post-treatment surveys revealed pain and symptom improvements and offered hope to individuals.

CONCLUSION

RSWT was implemented safely, without any negative treatment effects reported, and acted as a pain modulator to reduce sensitivity.

Self-Care Education on the Pain, Quality of Life, and Consequences of Disease in Patients with Knee Osteoarthritis

Introduction

Knee osteoarthritis (KOA) is one of the most common and prevalent debilitating chronic diseases across the world with various adverse effects such as pain and movement limitations which impact the health status and quality of life of the patients in the long run.

Objectives

This study aimed to investigate the effects of self-care education on pain, quality of life, and consequences of disease in patients with KOA in Southern Iran.

Methods

This is a randomized controlled clinical trial using a pretest-posttest design. Eighty patients with KOA were enrolled in this study and randomly allocated to a control and an intervention group. The data collection instruments included VAS: Visual Analog Scale, the SF-36 quality of life scale, and the Knee Injury and Osteoarthritis Outcome Score. The collected data were analyzed through SPSS v. 22, using descriptive tests, paired t-tests, independent t-tests, Chi-square, and ANOVA. A P level of <.05 was considered as the significant level.

Results

Before the self-care educational intervention, no statistically significant difference was found between the control and intervention groups in pain intensity, quality of life, and consequences of osteoarthritis. After the self-care educational intervention, the findings revealed a significant difference between the intervention group's mean ± standard deviation for pain intensity (41.25 ± 21.74), quality of life (49.87 ± 14.74), and consequences of KOA (39.06 ± 12.15), respectively (P < .05). However, in the control group, there was no significant difference.

Conclusion

Based on the results of this study, the positive effect of self-care education on patients with osteoarthritis was shown as to their pain intensity, quality of their lives, and reduction of the disease consequences. Thus, healthcare managers are recommended to apply this type of intervention for patients with osteoarthritis.

Accuracy and precision of responses to visual analog scales: Inter- and intra-individual variability

Visual analog scales (VASs) are gaining popularity for collecting responses in computer administration of psychometric tests and surveys. The VAS format consists of a line marked at its endpoints with the minimum and maximum positions that it covers for respondents to place a mark at their selected location. Creating the line with intermediate marks along its length was discouraged, but no empirical evidence has ever been produced to show that their absence does any good. We report a study that asked respondents to place marks at pre-selected locations on a 100-unit VAS line, first when it only had numerical labels (0 and 100) at its endpoints and then when intermediate locations (from 0 to 100 in steps of 20) were also labeled. The results show that settings are more accurate and more precise when the VAS line has intermediate tick marks: The average absolute error decreased from 3.02 units without intermediate marks to 0.82 units with them. Provision of intermediate tick marks also reduced substantially inter- and intra-individual variability in accuracy and precision: The standard deviation of absolute error decreased from 0.87 units without tick marks to 0.25 units with them and the standard deviation of signed distance to target decreased from 1.16 units without tick marks to 0.24 units with them. These results prompt the recommendation that the design of VASs includes intermediate tick marks along the length of the line.

Immediate and Long-Term Effects of Hyperbaric Oxygenation in Patients with Long COVID-19 Syndrome Using SF-36 Survey and VAS Score: A Clinical Pilot Study

(1) Background: Long COVID syndrome (LCS) is a heterogeneous long-standing condition following COVID-19 infection. Treatment options are limited to symptomatic measures, and no specific medication has been established. Hyperbaric oxygenation (HBO) has been found to have a positive impact on the treatment of COVID-19 infection. This study evaluates both the feasibility and outcome of supportive HBO in patients with LCS. (2) Methods: Within 17 months, 70 patients with proven LCS were prospectively included. Each patient underwent a cycle of 10 subsequent HBO treatment sessions administered for 75 min at 2.2 atmospheres. Evaluation of the patients was performed before the first and after the last HBO session and 3 months afterwards. Statistical evaluation was based on an intention-to-treat analysis using Fisher's exact test and Student's t-test for paired samples. (3) Results: In total, 59 patients (33 females, 26 males; mean age: 43.9 years; range: 23-74 years; median: 45.0) were evaluable. After HBO, a statistically significant improvement of physical functioning (p < 0.001), physical role (p = 0.01), energy (p < 0.001), emotional well-being (p < 0.001), social functioning (p < 0.001), pain (p = 0.01) and reduced limitation of activities (p < 0.001) was confirmed. (4) Conclusions: Physical functioning and both the physical and emotional role improved significantly and sustainably, suggesting HBO as a promising supportive therapeutic tool for the treatment of LCS.

Comparative study of pre- and postauricular flaps for external auditory canal defect reconstruction

BACKGROUND

Malignancies involving the external auditory canal deserve critical evaluation due to this area's aesthetic and functional importance. Flaps can be very useful for the restoration of the external auditory canal. A variety of flaps available for the surgical treatment of external acoustic meatus defects exist, depending on the precise location and size.

OBJECTIVES

Our study aimed to compare aesthetic and functional results in the postoncological reconstruction of external auditory canal defects using a preauricular flap and postauricular revolving door flap.

METHODS

Sixteen patients treated at our plastic surgery unit for defects involving the external auditory canal between January 2014 and December 2020 were included in the study. All defects were the result of a primary or secondary skin cancer excision. Patients were divided into two groups, one receiving the preauricular flap technique and the other the postauricular revolving door flap technique.

RESULTS

Three separate visual analog scales reported excellent scores for the two procedures, though the postauricular revolving door flap had slightly better results. Both preauricular flap and postauricular revolving door flap reconstructive techniques showed good options for external auditory canal reconstruction in postexcision skin cancer patients. From an aesthetic point of view, the revolving door flap appeared to be a more elegant surgical approach in this type of reconstruction because the scar was hidden in the postauricular sulcus.

CONCLUSIONS

Reconstruction with a postauricular revolving door flap allowed for a more natural movement with no external pedicle.

The simplified Chinese version of the Knee Injury and Osteoarthritis Outcomes Score (KOOS) in individuals with knee osteoarthritis for mainland China: the study of reliability and validity

BACKGROUND

The Knee Injury and Osteoarthritis Outcomes Score (KOOS) is a free clinical tool commonly used to evaluate the symptoms and functional status of patients with knee injury. For people who speak Chinese, the Hong Kong Chinese and Singapore Chinese versions are preferred. However, variations in the Chinese language and culture are influenced by the country's geography. KOOS for Mainland China has not been reported. Therefore, the current study was to cross-culturally translate the original English version into a simplified Chinese version and to investigate its psychometric properties.

METHODS

The simplified Chinese KOOS was obtained through forward-backward translation according to appropriate guidelines. A total of 158 individuals with knee osteoarthritis (KOA) were recruited from 13 hospitals in China to examine the psychometric properties. The test-retest questionnaire was performed at an interval of 5-7 days. Test-retest reliability and internal consistency were evaluated using the intraclass correlation coefficient (ICC) and Cronbach's alpha, respectively. The data of the first test were used to analyse the construct validity of the simplified Chinese KOOS and Chinese SF-36 through convergent and discriminant validity using Spearman's correlation coefficient.

RESULTS

Cross-cultural translation exhibited minor cultural differences, and the questionnaire was well understood by the patients. The data from 128 patients, used for the test-retest reliability study, showed good to excellent reliability, with an ICC of 0.808-0.976 for all KOOS subscales. The Cronbach's alpha for all subscales ranged from 0.757 to 0.970, indicating acceptable internal consistency. There was a low-to-high correlation between the five domains of the simplified Chinese version of the KOOS and all domains of the SF-36 in construct validity.

CONCLUSION

The simplified Chinese KOOS demonstrated acceptable reliability and validity. In clinical practice and research, this version can help provide valuable information on health-related quality of life for Chinese individuals with KOA in mainland China.

Short-Term Effects of Fruit Juice Enriched with Vitamin D3, n-3 PUFA, and Probiotics on Glycemic Responses: A Randomized Controlled Clinical Trial in Healthy Adults

This study aimed to determine the glycemic index (GI) of a commercial mixed fruit juice (apple, orange, grape, and pomegranate; FJ) fortified with vitamin D3 or n-3 polyunsaturated fatty acids (PUFA) or probiotics, and their combination, and their effects on glycemic responses and salivary insulin concentrations. In a randomized controlled, double-blind, crossover study, 11 healthy participants (25 ± 2 years; five women; body mass index = 23 ± 1 kg/m²) were randomly assigned to receive five types of FJs [vitD (with vitamin D3); n-3 (with n-3 PUFA); probiotics (with Lacticaseibacillus casei Shirota and Lacticaseibacillus rhamnosus GG); vitD-n-3-probiotics FJ (combination of vitD3-n-3-probiotics), control (regular FJ)], all containing 50 g available carbohydrate, and glucose as reference drink. All FJs provided low GI values (control: 54; vitD3: 52; n-3: 51; probiotics: 50; and vitD-n-3-probiotics combination: 52, on glucose scale). Compared to the FJ control, the enriched FJs produced different postprandial glycemic and insulinemic responses and affected satiety scores. All FJ types, regardless of the added biofunctional ingredients, attenuated postprandial glycemic responses, which may offer advantages to glycemic control.

The safety and efficacy of ultrasound versus fluoroscopic percutaneous nephrostomy: A prospective randomized study

Objective

The objective of this study is to compare the outcome of percutaneous nephrostomy by ultrasound (US) versus fluoroscopy including access time, volume of anesthesia required, success rate, and complications.

Methods

One hundred patients were enrolled in a prospective randomized study. Patients were divided into two groups, 50 cases each. Comparing the two groups was done regarding the need for dye, radiation effect, time taken, trial number, rate of complication, volume of anesthesia, and success rate.

Results

Patient demographics were comparable between both groups with no statistically significant difference. According to the modified Clavien-Dindo classification, the complications were Grade I (pain and mild hematuria) in each group. Procedural pain was present in 41 (82%) patients in Group I and in 48 (96%) patients in Group II. It was treated in both groups with a simple analgesic. Mild hematuria was present in 5 (10%) patients in the US group and 13 (26%) in the fluoroscopic group and treated by hemostatic drugs only. There was a statistically significant difference between both groups regarding the volume of required local anesthesia, the trial numbers, the puncture numbers, bleeding, extravasation, and change in the hemoglobin level.

Conclusion

US percutaneous renal access is a safe and effective modality with a high success rate, less operative time, and complication rate. However, a minimum of 50 cases with some pelvicalyceal system dilation may be preliminary requisites to achieve good orientation and competence in achieving safe US percutaneous renal access for future endourological procedures.

Dietary Behaviors, Serum 25(OH)D Levels and Quality of Life in Women with Osteoporotic Disorders

Data obtained in recent years clearly demonstrate the aging process of European populations. Consequently, the incidence of osteoporosis has been rising. The aim of this study is to assess the quality of life (QoL) of women with osteoporosis. A total of 260 women participated in this study. The patient group consisted of 170 women with osteoporotic disorders. The control group consisted of 90 healthy women. Participants' quality of life was measured with the Qualeffo-41 Questionnaire. The total 25(OH)D concentration level was assessed with an assay using the chemiluminescent immunoassay. To assess the pain level, the Visual Analogue Scale (VAS) was used. To assess dietary behaviors, data were obtained by a 13-item Food Frequency Questionnaire. To assess the nutrition knowledge of participants, the Beliefs and Eating Habits Questionnaire was used. Based on the frequency of food intake, participants were classified into three patterns of behavior, i.e., Prudent, Western, and Not Prudent-Not Western. The patients assessed their quality of life as average (36.6 ± 19.9 points). The most favorable scores were obtained in the domains of "Ability to do jobs around the house" and "Mobility". The worst rated domain among the respondents was "Mental function". There were significant differences identified in quality of life depending on diet, nutritional knowledge, comorbidities and occurrence of fractures in the subjects. The individuals in the "Prudent" group reported a significantly higher quality of life as compared to the "Not Prudent-Not Western" and "Western" groups and those with high nutritional knowledge as compared to those with moderate and low. Lower quality of life was also observed among women with comorbidities and with bone fractures. Depending on serum 25(OH)D levels, poorer quality of life was characterized women with vitamin D deficiency. Patient education, implementation of effective methods aimed at alleviating pain and maintaining the optimal concentration of vitamin D can help improve the quality of life in patients with osteoporotic disorders.

How should clinicians assess acute dental pain?: A review

Pain is the most common complaint in the dental field and may have a significant impact on the patients' quality of life. However, objective pain assessment is sometimes difficult, and medical and dental clinicians may encounter cases of pain in the head and neck region, making it difficult to establish differential diagnoses. This study aimed to review acute pain in clinical dentistry at each phase of dental procedures and discuss the current status and issues in the development of acute dental pain assessment methods in the future. Acute pain in clinical dentistry may differ in nature and modifying conditions of pain at each stage: before dental procedures, while visiting dentists, and during and after dental procedures. They are related to actual or potential tissue damage, and may be modified and aided by personal experiences, including psychological and social factors. With respect to the aging and multinational population and pandemic of infectious diseases, significant breakthroughs in the development of new pain scales without verbal descriptions are desirable. Furthermore, it is expected that a new pain scale that can be applied to acute pain in the head and neck regions, including the oral cavity, will be developed.
