Classifying disaster risk reduction strategies: conceptualizing and testing a novel integrated approach.

BACKGROUND: Although disaster risk reduction (DRR) addresses underlying causes and has been shown to be more cost-effective than other emergency management efforts, there is lack of systematized DRR categorization, leading to insufficient coherence in the terminology, planning, and implementation of DRR. The aim of this study was to conceptualize and test a novel integrated DRR framework that highlights the intersection between two existing classification systems. METHODS: Grounded theory was used to conceptualize a novel DRR framework. Next, deductive conceptual content analysis was used to categorize interventions from the 2019 Cities100 Report into the proposed DRR framework. The term "connection" indicates that an intervention can be categorized into a particular section of the novel integrated approach. A "connection" was determined to be present when the intervention description stated an explicit connection to health and to the concept within one of the categories from the novel approach. Further descriptive statistics were used to give insight into the distribution of DRR interventions across categories and into the application of the proposed framework. RESULTS: The resulting framework contains nine intersecting categories: "hazard, prospective", "hazard, corrective", "hazard, compensatory", "exposure, prospective", "exposure, corrective", "exposure, compensatory", "vulnerability, prospective", "vulnerability, corrective", and "vulnerability, compensatory". The thematic analysis elucidated trends and gaps in the types of interventions used within the 2019 Cities100 Report. For instance, exposure-prospective, exposure-compensatory, and vulnerability-compensatory were the most under-utilized strategies, accounting for only 3% of the total interventions. Further descriptive statistics showed that upper middle-income countries favored "hazard, corrective" strategies over other DRR categories while lower middle-income countries favored "exposure, corrective" over other DRR strategies. Finally, European cities had the highest percentage of DRR connections (51.39%) compared to the maximum possible DRR connections, while African cities had the lowest percentage of DRR connections (22.22%). CONCLUSIONS: The study suggests that the proposed DRR framework could potentially be used to systematically evaluate DRR interventions for missing elements, aiding in the design of more equitable and comprehensive DRR strategies.

Effects of telerehabilitation-based respiratory and corrective exercises among the elderly with thoracic hyper-kyphosis: a clinical trial.

BACKGROUND: Aging is associated with changes in the musculoskeletal system, including increased susceptibility to spine malalignments. Utilizing corrective exercises with a therapeutic emphasis can be beneficial in the elderly with thoracic spine hyperkyphosis. OBJECTIVE: This study aimed to investigate the effects of six weeks of telerehabilitation-based respiratory and corrective exercises on quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and chest expansion in the elderly with thoracic spine hyperkyphosis. METHODS: In this clinical trial, a total of 40 participants aged 60 and above with thoracic hyperkyphosis were randomly divided into the control (N = 20) and experimental (N = 20) groups. The experimental group performed the corrective exercises for six weeks (3 sessions per week). The control group performed general stretching exercises during the same time period. We measured the outcomes of quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and lung expansion before and after the intervention. Analysis of covariance (ANCOVA) was employed to analyze the data. A P-value ≤ 0.05 was considered statistically significant. RESULTS: Quality of life (P < 0.001, Effect Size (ES): 0.44), chest expansion (P < 0.001, ES: 0.56), thoracic kyphosis angle (P < 0.001, ES: 0.31), craniovertebral (P < 0.001, ES: 0.33), cranial (P < 0.001, ES: 0.38), and shoulder (P = 0.005, ES: 0.20) angles were significantly improved in the experimental group as compared with controls. However, no statistically significant difference was observed between the two groups in terms of physical ability (P = 0.251, ES: 0.04). CONCLUSION: It is therefore recommended that online corrective exercises be used in the rehabilitation protocol to improve the quality of life, posture, chest expansion, and disability in the elderly with thoracic kyphosis.

INDIVIDUAL ARTICLE: Real-World Patient Cases Using Botanical Serum-Containing Corrective Gel as an Adjunct to Aesthetic Facial Laser or Microneedling Radiofrequency (MRF) Treatment.

Integrated skin care is defined as the complementary use of topical treatments to nonsurgical facial rejuvenation procedures, such as lasers and radiofrequency microneedling devices, to produce pleasing aesthetic results. Real-world experience from expert dermatologists is invaluable in guiding patient treatment plans, as there are limited clinical trials on the efficacy of integrated skincare regimens. The SkinCeuticals (New York, NY) Phyto Corrective gel (botanical serum-containing corrective gel) contains a lightweight botanical serum that hydrates, calms, and soothes skin. It contains antioxidant and anti-inflammatory ingredients derived from plant and fruit extracts, making it an appealing option for adjunctive treatment of post-procedure erythema and swelling.  J Drugs Dermatol. 2024;23:3(Suppl 2):s3-s14.

Optimized Patient Outcomes With the Novel Modality of Corrective Chemical Peel and Neurotoxin on Same-Day Treatment.

BACKGROUND: This study was conducted to improve standards of care in the cosmetic treatment of sun damage, fine lines, and wrinkles. Chemical Peels and Neurotoxins have been traditionally used cosmetically as monotherapies. This study aimed to confirm that the same-day combination created no additional side effects while also improving outcomes. METHODS: The multi-generational study enrolled 30 patients with Fitzpatrick I-VI representation. The Roberts Skin Type Classification System was used to establish baseline patient information. Patients were treated with a VI Peel®, followed by Botox®. Objectively, photographic matching, Wrinkle Severity Scale, Uniformity of Pigment Scale, and Skin Tone Scales were used to evaluate skin improvement. Patient questionnaires were issued to assess satisfaction. RESULTS: Safety of the same-day combination was established with no adverse events reported. Improvements on the Wrinkle Severity Scale showed an average rating dropping from 1.46 to 0.59 representing a 60% improvement. Improvements on the Uniformity of Pigment Scale showed an average rating dropping from 2.27 to 0.92 representing a 59% improvement. Improvements on the Skin Tone Scale showed an average rating dropping from 2.35 to 0.71 representing a 70% improvement. Questionnaires correlated with objective findings with high satisfaction.  Conclusion: This study confirmed the safety of the same-day combination. The efficacy of VI Peel & Botox same-day treatment was clinically proven by the improvements to Wrinkle Severity, Uniformity of Pigment, and Skin Tone via photographic matching. While perception studies indicated strong patient satisfaction with the combination. J Drugs Dermatol. 2024;23(1):1349-1354.   doi:10.36849/JDD.7194R1.

Usefulness of the spectral shaping dual-source computed tomography imaging technique in posterior corrective fusion for adolescent idiopathic scoliosis.

PURPOSE: Since childhood exposure to radiation has been demonstrated to increase cancer risk with increase in radiation dose, reduced radiation exposure during computed tomography (CT) evaluation is desired for adolescent idiopathic scoliosis (AIS). Therefore, this retrospective study aimed to investigate the radiation dose of dual-source CT using a spectral shaping technique and the accuracy of the thoracic pedicle screw (TPS) placement for posterior spinal fusion (PSF) in patients with AIS. METHODS: Fifty-nine female patients with thoracic AIS who underwent PSF using CT-guided TPSs were included and divided into two groups comprised of 23 patients who underwent dual-source CT (DSCT) with a tin filter (DSCT group) and 36 who underwent conventional multislice CT (MSCT group). We assessed the CT radiation dose using the CT dose index (CTDIvol), effective dose (ED), and accuracy of TPS insertion according to the established Neo's classification. RESULTS: The DSCT and MSCT groups differed significantly (p < 0.001) in the mean CTDIvol (0.76 vs. 3.31 mGy, respectively) and ED (0.77 vs. 3.47 mSv, respectively). Although the correction rate of the main thoracic curve in the DSCT group was lower (65.7% vs. 71.2%) (p = 0.0126), the TPS accuracy (Grades 0-1) was similar in both groups (381 screws [88.8%] vs. 600 screws [88.4%], respectively) (p = 0.8133). No patient required replacement of malpositioned screws. CONCLUSION: Spectral shaping DSCT with a tube-based tin filter allowed a 75% radiation dose reduction while achieving TPS insertion accuracy similar to procedures based on conventional CT without spectral shaping.

Corrective mechanisms of motion extrapolation.

Transmission and processing of sensory information in the visual system takes time. For motion perception, our brain can overcome this intrinsic neural delay through extrapolation mechanisms and accurately predict the current position of a continuously moving object. But how does the system behave when the motion abruptly changes and the prediction becomes wrong? Here we address this question by studying the perceived position of a moving object with various abrupt motion changes by human observers. We developed a task in which a bar is monotonously moving horizontally, and then motion suddenly stops, reverses, or disappears-then-reverses around two vertical stationary reference lines. Our results showed that participants overestimated the position of the stopping bar but did not perceive an overshoot in the motion reversal condition. When a temporal gap was added at the reverse point, the perceptual overshoot of the end point scaled with the gap durations. Our model suggests that the overestimation of the object position when it disappears is not linear as a function of its speeds but gradually fades out. These results can thus be reconciled in a single process where there is an interplay of the cortical motion prediction mechanisms and the late sensory transient visual inputs.

Can We Control Lateral Shoulder Balance Through Proximal Thoracic Curve Correction in Lenke Type 2 Adolescent Idiopathic Scoliosis?

BACKGROUND: Proximal thoracic curve (PTC) correction has been considered to prevent lateral shoulder imbalance in Lenke Type 2 adolescent idiopathic scoliosis (AIS) patients; however, postoperative shoulder imbalance (PSI) commonly occurs despite these strategies with PTC correction. We investigated the hypothesis that PTC correction would not directly affect PSI in the majority of Lenke type 2 AIS cases. Furthermore, we investigated the risk factors for lateral PSI after corrective surgery. METHODS: This study examined the records for AIS patients with Lenke type 2 who underwent corrective surgery and followed up for >2 years. Patients were categorized into PSI (-); radiologic shoulder height (RSH)<15 mm, and PSI (+); RSH≥15 mm. Repeated measures analysis of variance was performed at preoperatively, postoperatively, 1 month, and final follow-up. Postoperative lateral shoulder imbalance was predicted by the identification of univariate analysis and multivariate analysis. RESULTS: Among the 151 patients reviewed, 29 (19.2%) showed PSI at final follow-up. Lateral shoulder balance parameters showed different directionalities between PSI (-) and (+) groups at postoperatively, 1 month, and final follow-up ( P <0.01 each). Preoperative PTC, middle thoracic curve (MTC) curve and MTC correction showed strong correlations with the RSH ( P =0.01, 0.03, and 0.04, respectively). However, PTC correction did not show a significant correlation with the RSH. Moreover, only a smaller MTC curve and larger MTC correction rate were related to lateral PSI in multivariate analysis. CONCLUSIONS: In Lenke type 2 AIS curves, the MTC curve and its correction predominantly influence lateral shoulder imbalance after corrective surgery, irrespective of the PTC correction extent. Consequently, overemphasizing the correction of the PTC curve may not necessarily lead to an improved lateral shoulder balance. When MTC curve is smaller, surgeons should be more careful for MCT overcorrection leading to a lateral shoulder imbalance. LEVEL OF EVIDENCE: Level III.

A violation of Fitts' Law occurs when a target range is presented before and during movement.

According to Fitts' Law, the time to reach a target (movement time, MT) increases with distance. A violation of Fitts' Law occurs when target positions are outlined before and during movement, as MTs are not different when reaching to the farthest and penultimate targets. One hypothesis posits that performers cognitively process the edges of a target array before the center, allowing for corrective movements to be completed more quickly when moving to edge targets compared to middle targets. The objective of this study was to test this hypothesis by displaying a target range rather than outlines of individual targets in an effort to identify the effects of array edges. Using a touch-screen laptop, participants (N = 24) were asked to reach to one of three targets which would appear within a presented range. Separately, targets were also presented without a range to determine if the display protocol could evoke Fitts' Law. Movements were assessed with the touch screen and optical position measurement. A main effect was found for relative position within a range (touch: F2,44 = 15.4, p < 0.001, η2p = 0.412; position: F2,40 = 15.6, p < 0.001, η2p = 0.439). As hypothesised, MT to the farthest target in a range was not significantly different than MT to the middle target (touch: p = 0.638, position: p = 0.449). No violation was found when a target range was not presented (touch: p = 0.003, position: p = 0.001). Thus, a target range reproduces the Fitts' Law violation previously documented with individually outlined targets, which supports and extends the discussed hypothesis.

Retrieval practice benefits for spelling performance in fifth-grade children.

Retrieval practice typically benefits learning in children, although little is known about the benefits of retrieval practice for learning spelling. We investigated this issue in three experiments with fifth-grade children from a low-income area of Brazil. In the experiments, children first read a list of words (study), and after a short interval wrote down the studied words after hearing and rereading them (copy) or after only hearing them (retrieval practice). After an interval of 4 days, spelling performance was greater for words from the retrieval practice condition than for words from the copy condition, but only when immediate corrective feedback was provided (Experiment 3). The current findings, therefore, suggest that retrieval practice followed by corrective feedback is an effective strategy to improve spelling performance of fifth-grade children.

The effect of a course of selected corrective exercises on posture, scapula-humeral rhythm and performance of adolescent volleyball players with upper cross syndrome.

BACKGROUND: This study aims to investigate the effect of a course of selected corrective exercises on posture, scapula-humeral rhythm and performance of adolescent volleyball players. METHODS: 30 adolescent volleyball players with upper cross syndrome were purposefully selected and assigned into 2 control and training groups. The degree of back curvature was evaluated using a flexible ruler, forward head and forward shoulder size by photographic method, scapula-humeral rhythm by Lateral Scapular Slide Test (LSST), and performance by closed kinetic chain test. The training group performed the exercises for 10 weeks. After the exercises, the post-test was administered. To analyze the data, analysis of co-variance tests and paired t-test at the level of 0.05 were employed. RESULTS: The research results showed that corrective exercises have a significant effect on abnormalities of forward head, forward shoulder, kyphosis, scapula-humeral rhythm and performance. CONCLUSIONS: Corrective exercises can be effective in reducing shoulder girdle and spine abnormalities and improving scapula- humeral rhythm and performance of volleyball players.

Analysis of health care professionals' incident reports on medical devices in Croatia.

AIM: To assess the quantity and quality of incident reports on medical devices by health care professionals from 2012 to 2021 and evaluate the effect of reporting on manufacturers' post-market surveillance. METHODS: Eighty-five incident reports were scored according to a self-developed evaluation system, and categorized as excellent, good, medium, qualified, and unqualified. The completeness of data in critical fields was assessed. For each report, the type and city of the reporter, and medical device risk class were extracted to calculate the frequency of report occurrence per risk class and outcomes for reportable reports. RESULTS: The number of reports received from health care professionals was low; the highest number of reports in a year was 17. The majority of reports were deemed as unqualified (61.18%) and only 4.71% as excellent. Still, 67.65% of incident reports importantly affected the manufacturer's post-market surveillance, either as added information that contributes to risk monitoring or directly triggering a field safety corrective action. CONCLUSION: The number of total reports and reports per year shows extensive underreporting in Croatia, and the quality of the provided reports is insufficient.

Minimally invasive corrective derotational osteotomy for proximal phalanx malrotation.

Fractures of the phalanges may result in a challenging complication known as malrotation, which can adversely affect the functionality of the fingers during flexion, leading to scissoring. The standard surgical approach for correcting this condition involves open corrective osteotomy and derotation, often at the level of the metacarpal, which includes the use of different techniques for osteotomy and fixation. However, postoperative complications such as finger stiffness and hardware irritation are common. To overcome these limitations, we present a novel and minimally invasive corrective osteotomy technique for malunited proximal phalanx fractures with rotational malalignment, which offers several advantages, such as accelerated rehabilitation and no prominent hardware.

[Improvement of quality characteristics of medical services based on patient satisfaction measurement results and QFD tools].

One of the directions to increase the effectiveness of medical organizations in the region is the development of managerial tools for improving the quality of medical services. The aim of the study is to develop an approach to improving the quality of medical services based on the results of measuring patient satisfaction with the quality of medical services, mapping satisfaction criteria to medical and technological characteristics of the quality of services, substantiation and selection of appropriate corrective measures. The method of measuring patient satisfaction with the quality of the provided medical service and the method of deploying quality functions ensuring transformation of patient needs and expectations into characteristics of service quality were used. The measurement of patients' satisfaction with the quality of medical services is carried out during medical and sociological research. The measurement results are obtained by statistical processing using a software set. To determine measures to improve the quality of cardiological services, the results of changing patient satisfaction were used in accordance with the method of deploying quality functions, which consists in implementing a number of steps that ensure the determination of a minimum set of additional requirements for medical services in order to meet the requirements of patients. This technique is supported by specialized software. Implementation of the proposed approach makes it possible to form tools aimed at creating an information model of medical services and ensure the change in the quality of such services demanded by patients.

Surgical sequence in anterior column realignment with posterior osteotomy is important for degree of adult spinal deformity correction: advantages and indications for posterior to anterior sequence.

BACKGROUND: We hypothesized that posterior osteotomy prior to ACR (Anterior column realignment) through P-A-P surgical sequence would permit a greater correction for deformity corrective surgery than the traditional A-P sequence without posterior osteotomy. This study aimed to determine the impact of the P-A-P sequence on the restoration of lumbar lordosis (LL) compared to the A-P sequence in deformity corrective surgery for adult spinal deformity (ASD) patients and to identify the characteristics of patients who require this sequence.  METHODS: Between 2017 and 2019, 260 ASD patients who had undergone combined corrective surgery were reviewed retrospectively. This study included 178 patients who underwent posterior osteotomy before the ACR (P-A group) and 82 patients who underwent the A-P sequence (A-P group). Sagittal spinopelvic parameters were determined from pre- and postoperative whole-spine radiographs and compared between the groups. To find better indications for the P-A-P sequence, we conducted additional analysis on postoperative outcomes of patients in the A-P group.  RESULTS: The P-A group showed a significantly higher change in LL (53.7° vs. 44.3°, p < 0.001), C7 sagittal vertical axis (C7 SVA: 197.4 mm vs. 146.1 mm, p = 0.021), segmental lordosis (SL) L2/3 (16.2° vs. 14.4°, p = 0.043), SL L3/4 (16.2° vs. 13.8°, p = 0.004), and SL L4/5 (15.1° vs. 11.3°, p = 0.001) compared to the A-P group. At the final follow-up, pelvic incidence (PI) minus LL mismatch (PI - LL mismatch) was significantly higher in the A-P group (13.4° vs. 2.9°, p < 0.001). Stepwise logistic regression analysis showed that age ≥ 75 years (odds ratio [OR] = 2.151; 95% confidence interval [CI], 1.414-3.272; p < 0.001), severe osteoporosis (OR = 2.824; 95% CI, 1.481-5.381; p = 0.002), rigid lumbar curve with dynamic changes in LL < 10° (OR = 5.150; 95% CI, 2.296-11.548; p < 0.001), and severe facet joint osteoarthritis (OR = 4.513; 95% CI, 1.958-10.402; p < 0.001) were independent risk factors for PI - LL mismatch ≥ 10° after A-P surgery. CONCLUSION: P-A-P sequence for deformity corrective surgery in ASD offers greater LL correction than the A-P sequence. Indications for the procedure include patients aged ≥ 75 years, severe osteoporosis, rigid lumbar curve with dynamic change in LL < 10°, or more than four facet joints of Pathria grade 3 in the lumbar region.

Dynamic Smoothing, Filtering and Differentiation of Signals Defining the Path of the UAV.

On the example of a control system for an unmanned aerial vehicle, we consider the problems of filtering, smoothing and restoring derivatives of reference action signals. These signals determine the desired spatial path of the plant at the first approximation. As a rule, researchers have considered these problems separately and have used different methods to solve each of them. The paper aims to develop a unified approach that provides a comprehensive solution to mentioned problems. We propose a dynamic admissible path generator. It is constructed as a copy of the canonical control plant model with smooth and bounded sigmoid corrective actions. For the deterministic case, a synthesis procedure has been developed, which ensures that the output variables of the generator track a non-smooth reference signal. Moreover, it considers the constraints on the velocity and acceleration of the plant. As a result, the generator variables produce a naturally smoothed spatial curve and its derivatives, which are realizable reference actions for the plant. The construction of the generator does not require exact knowledge of the plant parameters. Its dynamic order is less than that of the standard differentiators. We confirm the effectiveness of the approach by the results of numerical simulation.

Exudate - phenolphthalein pH test for evaluation of validity in seeds of Libidibia ferrea.

Seed companies are looking for promising, quick and effective alternatives to determine the physiological quality of seeds. The objective of the current work was to study the efficiency of the exudate - phenolphthalein pH test to evaluate the seeds of two lots of Libidibia ferrea (Mart. ex Tul.) L. P. Queiroz var. ferrea. The statistical design for the the exudate - phenolphthalein pH test was completely randomized with four replicates of 50 seeds in a factorial design (2 x 5), two seed lots and five soaking periods (30, 60, 90, 120, and 150 minutes), respectively, using two constant temperatures (25 and 30°C). The percentage of viability and germination of the seeds did not differ in the temperatures of 25 and 30°C and in the soaking periods by the exudate - phenolphthalein pH test. Thus, it is recommended that the test be conducted for at least 30 minutes in distilled and deionized water at the constant temperature of 25 or 30°C to evaluate the vigor of the Libidibia ferrea.

A reversible calix[4]arene armed phenolphthalein based fluorescent probe for the detection of Zn2+ and an application in living cells.

A reversible and easy assembled fluorescent sensor based on calix[4]arene and phenolphthalein (C4P) was developed for selective zinc ion (Zn2+ ) sensing in aqueous samples. The probe C4P demonstrated high selective and sensitive detection towards Zn2+ over other competitive metal ions. Interaction of Zn2+ with a solution of C4P resulted in a considerable increment in emission intensity at 440 nm (λex  = 365 nm) due to the suppression of photoinduced electron transfer (PET) process and the restriction of C=N isomerization. The binding constant (Ka ) of C4P with Zn2+ was calculated to be 4.50 × 1011  M-2 and also the limit of detection of C4P for Zn2+ was as low as 0.108 µM (at 10-7  M level). Moreover, the fluorescence imaging in the human colon cancer cells suggested that C4P had great potential to be used to examine Zn2+ in vivo.

Colorimetric detection of Staphylococcus aureus using gold nanorods labeled with yolk immunoglobulin and urease, magnetic beads, and a phenolphthalein impregnated test paper.

A colorimetric test is described for the rapid detection of Staphylococcus aureus (SA). Gold nanorods (AuNRs) are first labeled with urease and yolk immunoglobulin (IgY). This probe can specifically bind SA. In the next step, nonspecific magnetic beads and sample are added. This leads to the formation of the AuNR-IgY-SA-nMB immunocomplex which is then magnetically separated. Finally, a solution of urea is added to the supernatant. Ureases catalyzes the decomposition of urea which results in an increase in the pH value. The increase in the pH value is detected by using a phenolphthalein test paper which undergoes a color change from white to pink. The analytical process can be completed within 20 min. The method is highly specific and can detect as little as 476 cfu·mL-1. It was verified by analyzing contaminated Chinese cabbage and beef samples, and 1000 cfu·mL-1 of SA were accurately detected. Graphical abstract Schematic representation of a colorimetric method for the detection of Staphylococcus aureus based on the immunocomplex formed from dual-labeled gold nanorod (AuNR) probe, bacteria and non-specific magnetic bead (nMB). This method can be completed within 20 min.

Laxative-Induced Contact Dermatitis.

A 5-year-old female with Charcot-Marie-Tooth neuropathy and a history of constipation presented to the emergency department with a new blistering buttocks rash, which was initially concerning for nonaccidental burn. Upon further investigation, it was found that Ex-Lax had been given to the patient for constipation. This had resulted in a bowel movement, which led to an irritant dermatitis. The patient was eventually diagnosed with senna-induced erosive diaper dermatitis. This case report highlights the importance of a thorough history and physical examination to prevent an unnecessary child abuse work-up.

Colorimetric Detection of Thiophenol Based on a Phenolphthalein Derivative and Its Application as a Molecular Logic Gate.

A phenolphthalein-based colorimetric probe bearing a dinitrobenzene group is reported as a thiophenol (PhSH)-selective chemodosimeter. PhSH can react with chemodosimeter 1 to afford phenolphthalein. The addition of PhSH to the aqueous solution of 1 followed by a change in pH of the resulting solution to basic induces a selective color change from colorless to pink. Furthermore, using PhSH and base as inputs and color change of 1 by naked eye as an output, leads to the construction of an AND logic gate.
