Cataract extraction combined with IOL implantation is the only effective method for the treatment of cataracts at present. Patients put forward higher requirements for the postoperative effect of cataracts to meet the needs and improve the quality of life. A previous studyTypically, doctors implanted monofocal IOL for patients during cataract surgery, which could provide good distance only. Thus, the patients required spectacles correction for intermediate and near vision postoperatively. The emergence of trifocal IOL makes it possible for patients to have spectacles independence after surgery. Trifocal IOL can converge parallel light into far, intermediate, and near focus and provide a good functional vision at all distances with high levels of spectacles independence and patient satisfaction. In the current study, group A (with 839MP) had better monocular UCVA in the distance, intermediate, and near vision, while BCVA had no difference.When different types of IOLs were implanted, statistically significant differences were detected in the area-of-focus metric between groups A and B in the distance area, intermediate area, and near area. The range from 0-4.34 mm diameter center is +1.66 D, +3.33 D, with additional medium and near vision trifocal design, and that for 4.34-6 mm is +3.33 D bifocal designed with additional near vision. This design results in wider and better vision after trifocal IOL implantation, which in turn, leads to better visual function, higher satisfaction, spectacles independence, and quality of life, especially in the intermediate and near distance. The study by Tarib et alAlthough the contrast sensitivity values of patients with scotopic and photopic vision after trifocal IOL implantation were within the normal range, Group B had significantly higher CSF under UCVA at 3 months after the operation in our study.Due to the diffraction design of this trifocal IOL, patients had more visual interference after implantation, especially glare and halos. However, no statistical difference was detected in the visual interference between the 2 groups. This may be related to the special design of the trifocal IOL, making it to have high light energy utilization. Interestingly, we found that 2 patients in group A had an abnormal color vision after implantation, and their vision was slightly bluish, while no patient reaction was noted in group B. This phenomenon could be attributed to the diffraction ring design of this trifocal IOL. The height of the diffraction step of IOL with different diopters determined the passage of specific diffracted light waves, while the wavelengths of light of different colors varied, resulting in abnormal color vision in some patients due to the diffraction of light waves after implantation. However, this part of the abnormality could be gradually alleviated after brain fusion and adaptation and did not affect the patient’s daily life. Nonetheless, this finding needs to be substantiated further. However, this study was limited by the sample size and the recruitment of patients from only one hospital.In conclusion, compared to monofocal intraocular lens, the trifocal intraocular lens provides a full range of clear vision for the majority of patients with simple cataracts and improves the rate of spectacle independence and patients’ satisfaction, but reduces the patients’ contrast sensitivity and cause visual impairment. However, the objective quality of vision did not show any difference and would not significantly affect the daily life of the patients. Despite visual interference, trifocal intraocular lenses are preferred by patients. By strictly controlling the indications of trifocal intraocular lenses implantation, such as spherical aberration, the total corneal irregular astigmatism in 4-mm area, and the kappa angle, this visual interference can be reduced to a minimum and would not affect the daily life of patients.

Study Design and Setting
This study reports women’s childbirth experiences 2 hr, 3 months, and 12 months after participation in the Room4Birth randomized controlled superiority trial (RCT) in Sweden (Randomization was undertaken between January 2019 and October 2020 at a labor ward located in western Sweden and with an annual birth rate of around 4,000 births (Photos of (A) one of the regular birthing rooms and (B) the new birthing room.New birthing room where the medico-technical devices were hidden behind wood-paneled walls (A) that could be rolled up if required (B).

Sample and Recruitment
RECRUITMENT
Eligible participants for randomization were women aged 18 or more, classified as Robson 1 (Participant recruitment was carried out by the midwives and assistant nurses at the labor ward. Eligible women were asked to participate after labor ward arrival and confirmed active stage of labor, if both a regular room and the new room were vacant. All women gave signed, written consent to participate, and the time interval from labor ward arrival to randomization was set to be as short as possible to ensure an early allocation to the randomized room. The randomly computer-generated allocation list was managed by an independent agency. Information about the allocated room was printed in sealed, opaque envelopes sequentially placed in a study box at the labor ward. The recruiting care provider was not aware of the randomization sequence, and the independent agency ensured that the allocation list was followed. The women were provided with a four-digit ID code, which was printed on the sealed envelope.

REGRESSION
To compare differences between the two randomized groups, χA linear mixed effects model was used to describe the group differences in childbirth experience over the three time points.

Methodological Considerations
The advantages of our study include its randomized design and the high response rates of the follow-up questionnaires. Another strength is that the participants were asked to report their childbirth experiences at three different time points during their first year after birth. This made it possible to study how the experience of birth changes over time. Unfortunately, this study had a limited sample size, which was not sufficient to detect an effect in the 12-month follow-up. The sample size estimation was based on the primary outcome of the Room4Birth RCT (To explore the multidimensional phenomenon of childbirth experience, we chose to include three different measurements (VAS-OCE, FOBS, and CEQ2). Nevertheless, it is challenging to measure experiences quantitatively, since aspects such as context, social support, interpersonal relationships, and physical and emotional senses need to be taken into consideration (The place and space for birth is not just created through the physical design but also through those who inhabit and interact within the room (
PMC9755691
Conclusion
The findings of this study show the benefit of acknowledging the physical design of hospital-based birthing rooms. Nulliparous women randomized to a birthing room designed with person-centered considerations aimed at supporting the physiology of birth reported more positive overall childbirth experiences 3 and 12 months after birth than women randomized to a regular birthing room. When designing interventions and environments in hospital settings, it is essential to understand the psychological and existential dimensions of childbirth, since the dynamics and changes in labor and birth experiences influence outcomes. It is also essential to understand how remnants of archaic nest-building behaviors and experiences are still present in birthing women of today. The findings of the study confirm that the physical design matters to women in their assessment of childbirth experience, but we were unable to show the actual effect of the new room on the variables explored. Therefore, additional research is needed that qualitatively explores the impact of the birth environment design on women’s long-term childbirth experiences.
PMC9755691
Implications for Practice
From a mental health perspective, it is essential to understand the importance of emotional well-being in the transition to parenthood.A birthing room designed with person-centered considerations, where women and companions can adapt features and functions in the room in accordance with personal needs and requirements, positively impacts women’s birth experiences 3 and 12 months after birth.When striving to optimize care during labor and birth, both the physical and the psychosocial environment need to be improved.To value emotions, birth physiology and person-centered perspectives in labor ward design may be one strategy to help reverse the rising trend of medical interventions in labor that is observed in many hospital settings.

BREAST CANCER
The active acupuncture regimen produced better outcomes than the sham control in improving sleep onset latency, total sleep time and sleep efficiency in breast cancer women with chemotherapy-associated insomnia, although there was no significant difference in reducing insomnia severity. Active acupuncture had significantly greater effects in improving anxiety, depression and quality of life. Participants of the active acupuncture group showed a markedly higher cessation rate of sleeping medications. Active acupuncture regimen could be considered as an effective option for chemotherapy-associated insomnia and a tapering approach to reduce and even replace use of sleeping medications in breast cancer patients.

Introduction
attention-deficit/hyperactivity disorder, ADHD
SPENCER, GROWTH SUPPRESSION
Methylphenidate (MPH) is a commonly prescribed medication for attention-deficit/hyperactivity disorder (ADHD) because of its efficacy for symptom reduction and overall favorable safety record. MPH is often prescribed for long-term use in patients with ADHD (Storebø et al. This formulation of SDX/d-MPH (Azstarys™; Corium, LLC, Boston, MA) was approved by the US Food and Drug Administration for patients aged 6 years and older with ADHD.In a pivotal, randomized, placebo-controlled, double-blind laboratory classroom study of children with ADHD, SDX/d-MPH treatment was shown to significantly improve ADHD symptoms compared with placebo (Kollins et al. A subsequent, 1-year, open-label safety study of SDX/d-MPH in children with ADHD showed that SDX/d-MPH was well tolerated and had sustained efficacy during the 1-year treatment period (Childress et al. Long-term treatment with stimulants, such as MPH for ADHD, in children has been associated with modest slowing of growth velocity and prescribing information for these treatments warns of long-term growth suppression, which can cause concern and limit their use (Spencer et al.

Study design
The study design included a 30-day screening phase, a 3-week DO phase, a 360-day treatment phase, and a follow-up visit. Only new subjects underwent screening and DO. During the DO phase, new subjects were titrated to their optimized dose based on the best dose response and individual tolerability to the treatment (Childress et al. New subjects started treatment with the 39.2/7.8 mg dose of SDX/d-MPH daily, which is a molar equivalent to 30 mg of total d-MPH HCl, for 7 days. If needed, dose adjustments were performed based on the investigator's assessment of the subject at weekly intervals. The SDX/d-MPH dose could be increased to 52.3/10.4 mg (40 mg molar equivalent of total d-MPH HCl), decreased to 26.1/5.2 mg (20 mg molar equivalent of total d-MPH HCl), or maintained at the same dose for the next week of dosing.The dose at the end of the third week was assigned as the optimized dose. Subjects who rolled over from the pivotal study remained on their optimized dose from that study. The optimized SDX/d-MPH dose was used during the treatment phase. All subjects were administered 1 capsule daily of their optimized dose of SDX/d-MPH. Weight and height analyses were conducted in the treatment phase safety population of enrolled subjects. This population included those who received at least 1 dose of study medication and had at least 1 postdose safety assessment in the treatment phase. Completers are those subjects that completed 12 months of treatment.

The percentage of subjects with clinically notable weight loss, defined as a weight decrease from baseline >7%, was 8.7% at 30 days. The percentage of subjects with weight loss increased over time, peaking at 14.5% of subjects at 4 months and then declining to 5.2% of subjects at the end of the study (360 days).

The safety and tolerability results from this 1-year open-label study of SDX/d-MPH in children with ADHD have been previously reported (Childress et al. Other studies of MPH in children with ADHD also observed similarly higher baseline weight and height than their reference samples (Swanson et al. A The mean weight changes as a percent from baseline-by-baseline BMI quartile groups showed that all four baseline BMI quartile groups had an initial weight decrease during the first to fourth months in the treatment phase, with a notable smaller and shorter weight decrease in baseline BMI quartile 1 compared with the other three baseline BMI quartile groups.The relative weight gain after the initial decline through the end of treatment was higher in subjects in the first and second baseline BMI quartile groups compared with subjects in the third and fourth baseline BMI quartile groups. This difference in weight gain indicates that subjects with a higher baseline BMI experienced a larger initial reduction in weight gain than subjects with a lower baseline BMI. Relative weight gain after ∼3 months of treatment appeared similar between all baseline BMI quartiles.With respect to height, the positive mean baseline height The change in height The effects of long-term treatment of stimulants on weight and height in pediatric patients are well documented (Spencer et al. However, that study was of a much shorter span than the current study, consisting of a 3-week dose optimization phase followed by a 2-week maintenance phase, and it is possible that study had not reached maximum effect on body weight that may have been measured later in treatment had the treatment continued.In a 21-month study with a dose-optimized long-acting MPH formulation in 407 children aged 6–13 years with ADHD (Spencer et al. In a more recent 12-month open-label safety study of extended-release MPH in children aged 4–5 years with ADHD, subjects entering the study were heavier and taller than the reference population (Childress et al. In the extended-release MPH study (Childress et al. The limitations of this study include the open-label nature of the study design and the lack of a control placebo arm or a comparator product. The analysis of a drug effect on body weight changes over time by itself is limited because children are expected to grow and gain weight as they age, even during SDX/d-MPH treatment. In addition, some of the subjects who entered this study were not stimulant naive, as some had been previously treated with SDX/d-MPH in the antecedent pivotal study. Thus, previous stimulant exposure may have impacted baseline height and weight measures, resulting in an underestimate of growth velocity changes.

Conclusion
In this study, we show that long-term treatment for up to 1 year with SDX/d-MPH was associated with modest reductions in expected weight and lower-than-expected increases in height, effects that plateaued or diminished later in treatment. Although both weight and height decreased compared with the reference population, the decrease was less than what is clinically significant.

Clinical Significance
This phase 3 clinical trial of SDX/d-MPH in children aged 6–12 years showed that the overall effects of SDX/d-MPH on growth velocity were minimal and changes were in a range considered not clinically significant.

Discussion
RESPIRATORY TRACT INFECTIONS, COMMUNITY-ACQUIRED PNEUMONIA
We observed a discrepancy in azithromycin susceptibility depending on whether using breakpoints from EUCAST or CLSI guidelines for interpretation. All 13 PNSP isolates harboring genetic determinants for macrolide resistance were correctly identified as resistant to erythromycin and azithromycin (all with MIC ≥ 4 µg/mL) regardless of which breakpoints were used (sensitivity 100%, 13/13). Using the EUCAST breakpoints appeared to overestimate azithromycin resistance, as all 13 erythromycin-susceptible PNSP without genetic determinants of macrolide resistance were interpreted as resistant to azithromycin (MIC-values from 0.5 to 2, specificity 0%, 0/13). Using CLSI breakpoints only misclassified two such isolates (MIC 2 µg/mL, specificity 85%, 11/13). Therefore, relying on current EUCAST guidelines appears to overestimate azithromycin resistance and could in the clinical perspective lead to unnecessary use of more broad-spectrum antibiotics. Our findings suggest that the EUCAST guidelines currently use a too low cutoff for MIC-values for azithromycin resistance in pneumococci.PNSP susceptibility to erythromycin, on the other hand, was similar using both EUCAST and CLSI breakpoints, and the phenotypic findings correlated well with the identified genotypic resistance markers. To avoid variations in interpretation, our findings call for AST guidelines to be harmonized. Both CLSI and EUCAST state that erythromycin susceptibility can predict susceptibility to clarithromycin, azithromycin, dirithromycin, and roxithromycin [In Tanzania, macrolides are commonly used to treat respiratory tract infections. In the treatment of community-acquired pneumonia, erythromycin and azithromycin are used as first and second line treatment, respectively [The most common phenotype was MLSPrevious studies have shown that tetracycline and macrolide resistance genes are carried on mobile genetic elements, composite conjugative transposons, Tn
