Review
The surgical treatment of lymphedema can be conducted alone or in combination with microsurgical autologous breast reconstruction. We performed a systematic review of the literature at PubMed database regarding autologous breast reconstruction for deep inferior epigastric perforators (DIEP) or muscle-sparing transverse rectus abdominis myocutaneous (ms-TRAM) and vascularized lymph node transfer (VLNT) in patients with lymphedema following breast cancer surgery. We hypothesized that autologous breast reconstruction combined with VLNT has positive outcomes. Eligibility criteria included investigations reporting data studies evaluating female patients with lymphedema in an upper extremity after breast cancer who underwent autologous breast reconstruction combined with VLNT. The search resulted in 93 potential papers, but only 6 studies fulfilled the study eligibility criteria. The total number of patients was 103. Most of the studies evaluated the outcomes in patients treated with DIEP or ms-TRAM combined with VLNT. The studies described groin lymph node transfer as treatment for lymphedema. In most of the studies, all patients reported a reduction of arm circumference, volume, and symptoms of the upper extremity with lymphedema comparing the preoperative to the postoperative period. Overall, patients experienced successful breast reconstruction. All authors reported reduction of the circumferential size of the affected upper limb, as well as a decrease in cellulitis, in addition to favorable breast reconstruction results.

Meta-Analysis Review
BACKGROUND
Numerous studies have evaluated the use of autologous abdominal tissue for breast reconstruction; nevertheless, complications and donor site morbidity rates vary significantly. The study aims to compare the literature regarding morbidity of the donor site and complication rates of breast reconstruction with autologous abdominal flaps.
METHODS
The databases of MEDLINE, EBSCO, Scopus, Wiley Library, and Web of Sciences were searched for studies that compared different flaps in terms of complications and donor site morbidity. The procedures studied included pedicled transverse rectus abdominis myocutaneous flap (pTRAM), free TRAM (fTRAM), deep inferior epigastric perforator (DIEP), and superficial inferior epigastric artery perforator (SIEA) flaps. A total of 34 studies were included. Of these, 28 were retrospective studies and 9 were prospective cohort studies.
RESULTS
When compared to DIEP, fTRAM flaps were found to have a decreased incidence of flap fat necrosis, hematoma, and total thrombotic events, yet a higher risk of donor site hernia/bulging. pTRAM flaps were also associated with an increased risk of hernia/bulging at the donor site, as well as wound infection, yet flap hematoma was less common. On the other hand, SIEA flaps showed the lowest risk of donor site hernia/bulging while still having a high risk of wound infection.
CONCLUSION
fTRAM procedures comparatively had the least complications. However, regarding flap choice, patients would benefit most from a case-by-case analysis, taking into consideration individual risk factors and preferences.

Review
PURPOSE
Muscle ultrasound has emerged as a promising method in the diagnostic work-up of sarcopenia. The objective of this scoping review was to explore the validity of muscle ultrasound against the latest sarcopenia definitions among older adults.
METHODS
We adhered to the PRISMA guidelines for scoping reviews. A systematic search of databases was performed by two independent reviewers. All articles comparing the performance of ultrasound to an internationally acknowledged sarcopenia definition among older adults (≥60 years) and published between 2019/01/01 (the year updated sarcopenia definitions were introduced) and 2023/11/15 were included. Data were extracted and collated by muscle and muscle parameters.
RESULTS
Out of 2290 articles screened, six studies comprising 24 validity tests among a total of 1619 older adults (mean age 74.1 years, 52.2% female) were included. The validity tests investigated the rectus femoris (n = 7), biceps brachii (n = 5), gastrocnemius medialis (n = 4), tibialis anterior (n = 4), soleus (n = 3), and rectus abdominis (n = 1). The parameter muscle thickness (MT) (n = 14) was most commonly measured. The latest European and Asian sarcopenia definitions (EWGSOP2, AWGS2) were applied as reference standards in four validity tests each. None of the studies used the Sarcopenia Definition and Outcome Consortium (SDOC) criteria. The highest area under the curve AUC (0.92, 95% confidence interval [CI] 0.89-0.94) was found for the muscle thickness of the rectus femoris muscle. Due to substantial heterogeneity among the studies, pooling of data using a meta-analytic approach was not feasible.
CONCLUSION
Limited number of studies have examined the validity of muscle ultrasound for diagnosing sarcopenia based on recent definitions among older adults. Thereby, muscle thickness of the rectus femoris showed promising results regarding validity. Further studies are needed to investigate the validity of key muscles and to validate muscle ultrasound among older hospitalized patients.

Review
Low back pain represents the leading cause of disability since 1990. In 90% of cases, it is classified as non-specific low back pain, being chronic in 10% of subjects. Ultrasound has proven to be an effective measurement tool to observe changes in the activity and morphology of the abdominal muscles. This article reviews which core synergies are studied with ultrasound in healthy subjects and with chronic non-specific low back pain. A systematic review was conducted on studies analyzing synergies between two or more core muscles. Publications from 2005 until July 2021 were identified by performing structured searched in Pubmed/MEDLINE, PEDro and WOS. Fifteen studies were eligible for the final systematic review. A total of 56% of the studies established synergies between the core muscles and 44% between the homo and contralateral sides of the core muscles. The most studied core synergies were transversus abdominis, internal oblique and external oblique followed by the rectus abdominis and the lumbar multifidus. No studies establishing synergies with diaphragm and pelvic floor were found. Eight studies were conducted in healthy subjects, five studies in subjects with chronic non-specific low back pain compared to healthy subjects and two studies in subjects with chronic non-specific low back pain.

Review
The effect of electromyographic (EMG) activity on agonist muscles during exercises performed on stable and unstable surfaces remains uncertain. We aimed to review the literature regarding the comparison of the EMG activity of the agonist muscles of exercises performed on stable and unstable surfaces. Eighty-six studies that evaluated the EMG activity of 1783 individuals during exercises for the lower limbs, upper limbs, and core were included. The EMG activities of the pectoralis major (SMD = 0.28 [95% CI 0.09, 0.47]) and triceps brachii muscles (SMD = 0.45 [95% CI 0.25, 0.66]) were significantly increased when the unstable device was added to the exercise. Likewise, the EMG activity of all core muscles showed a significant increase with the unstable surface during the exercises, such as the rectus abdominis (SMD = 0.51 [95% CI 0.37, 0.66]), external oblique (SMD = 0.44 [95% CI 0.28, 0.61]), internal oblique (SMD = 1.04 [95% CI 0.02, 2.07]), erector spinae (SMD = 0.37 [95% CI 0.04, 0.71]), and lumbar multifidus (SMD = 0.35 [95% CI 0.08, 0.61]). However, the lower limb muscles did not show greater EMG activity during the exercise with unstable surfaces compared to the stable surface. In conclusion, unstable conditions increase the EMG activity of some upper limb and core muscles compared to a stable surface.

Meta-Analysis
BACKGROUND
Anticipatory postural adjustments (APAs) are a feedforward mechanism triggered in advance to a predictable perturbation, to help the individual counteract mechanical effects that the disturbance may cause. Whether or not this strategy is compromised in the elderly is not a consensus in the literature.
METHODS
In this systematic review with meta-analysis, we investigated aging effects on postural control, based on anticipatory postural adjustments (APAs). We selected 11 eligible articles of the following databases: Lilacs, SciELO, PubMed, Cochrane Central, Embase, and CINAHL, involving 324 research participants, assessing their methodological quality and extracting electromyographic, posturographic, and kinematic measurements. We included studies that investigated the occurrence of APAs in healthy younger and older adults, published before 10th August 2022, in English. Studies involving participant with conditions that may affect balance or that did not report measures of onset or amplitude of electromyography (EMG), COP, or kinematics were excluded. To analyze the aggregated results from these studies, we performed the analysis based on the outcome measures (EMG, COP, or kinematic measures) used in individual studies. We calculated differences between younger and older adult groups as the mean differences between the groups and the estimated effect. Egger's test was conducted to evaluate whether this meta-analysis had publication bias.
RESULTS
Through this review, older adults showed no significant difference in the velocity to perform a movement compared to the younger adults (MD 0.95, 95% CI -0.86, 2.76, I = 82%), but both muscle onset and center of pressure (COP) onset were significantly more delayed in older than in younger adults: erector spinae (MD -31.44, 95% CI -61.79, -1.09, I = 95%); rectus abdominis (RA) (MD -31.51, 95% CI -70.58, -3.57, I = 85%); tibialis anterior (TA) (MD -44.70, 95% CI -94.30, 4.91, I = 63%); soleus (SOL) (MD -37.74, 95% CI -65.43, -10.05, I = 91%); gastrocnemius (GAS) (MD -120.59, 95% CI -206.70, -34.49, I = 94%); quadriceps (Q) (MD -17.42, 95% CI -34.73, -0.12, I = 0%); biceps femoris (BF) (MD -117.47, 95% CI -192.55, -42.70, I = 97%); COP onset (MD -45.28, 95% CI -89.57, -0.98, I = 93%), and COP apa (COPapa) (MD 2.35, 95% CI -0.09, 4.79, I = 64%). These changes did not seem to be linked to the speed of movement but possibly to age-related physiological changes that indicated decreased motor control during APAs in older adults.
CONCLUSIONS
Older adults use different postural strategies that aim to increase the safety margin and stabilize the body to perform the movement, according to the requirements imposed, and this should be considered in rehabilitation protocols.

Meta-Analysis
BACKGROUND
Different regional anesthesia (RA) techniques have been used for laparoscopic cholecystectomy (LC), but there is no consensus on their comparative effectiveness. Our objective was to evaluate the effect of RA techniques on patients undergoing LC using a network meta-analysis approach.
METHODS
We conducted a systematic review and network meta-analysis. We searched PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and Web of Science (Science and Social Science Citation Index) using the following PICOS criteria: (P) adult patients undergoing LC; (I) any RA single-shot technique with injection of local anesthetics; (C) placebo or no intervention; (O) postoperative opioid consumption expressed as morphine milligram equivalents (MME), rest pain at 12 h and 24 h post-operation, postoperative nausea and vomiting (PONV), length of stay; and (S) randomized controlled trials.
RESULTS
A total of 84 studies were included. With the exception of the rectus sheath block (P = 0.301), the RA techniques were superior to placebo at reducing opioid consumption. Regarding postoperative pain, the transversus abdominis plane (TAP) block (-1.80 on an 11-point pain scale) and erector spinae plane (ESP) block (-1.33 on an 11-point pain scale) were the most effective at 12 and 24 h. The TAP block was also associated with the greatest reduction in PONV.
CONCLUSIONS
RA techniques are effective at reducing intraoperative opioid use, postoperative pain, and PONV in patients undergoing LC. Patients benefit the most from the bilateral paravertebral, ESP, quadratus lumborum, and TAP blocks.

Review
Many ultrasound-guided procedures are available for administering analgesia via peripheral nerve blockade. This systematic review aims to compare different ultrasound-guided procedures to determine which procedure is better suited for pediatric abdominal surgeries. The objective is to understand the efficacy of ultrasound-guided procedures for postoperative pain management in children undergoing abdominal surgeries and to identify which procedure takes less time and is better suited for a particular surgery. A systematic literature search was performed in PubMed, SCOPUS, Central Cochrane Registry of Controlled Trials (The Cochrane Library), and ScienceDirect databases for pediatric abdominal surgeries conducted with ultrasound-guided procedures for administering analgesia. We included studies involving randomized controlled trials (RCTs). Quasi-randomized controlled studies, prospective, retrospective observational studies, case series, case reports, letters, editorials, comments, animal studies, and studies from non-English literature were excluded. We reviewed 13 articles with 910 patients included. Age groups varied from 6 months to 21 years. The most common block used was the transversus abdominis block (47.76%), and the most common surgery performed was hernia and hydrocele (52.10%). Quadratus lumborum block was used in 26.92%, erector spinae block in 8.97%, modified transversus abdominus block and rectus sheath block in 9.62%, and ilioinguinal block in 6.73% of the patients. No complications were reported in any of the studies. Transversus abdominus block is less effective in two of the studies. Each procedure for pediatric postoperative analgesia has specific advantages and limitations, highlighting the complexity of tailoring interventions. Our review focuses on the advancements in ultrasound-guided analgesia for lower abdominal surgeries in pediatric patients while also emphasizing the need for future randomized controlled trials (RCTs) to compare efficacy, standardize practices, and improve patient outcomes.

Meta-Analysis
BACKGROUND
Single-injection regional analgesia techniques can provide effective analgesia for abdominal hysterectomy. However, few randomized controlled trials (RCTs) have directly compared these techniques for total abdominal hysterectomy (TAH), and the best strategy remains unknown.
OBJECTIVES
In this network meta-analysis, we compared the analgesic efficacy of single-injection regional analgesia techniques in patients who underwent TAH.
STUDY DESIGN
A systematic review and network meta-analysis.
METHODS
We searched the PubMed, Embase, Cochrane, and CINAHL databases for relevant trials from inception until April 2022. RCTs that examined single-injection regional analgesia techniques for TAH were included. Random-effects network meta-analyses were performed using the frequentist approach. The primary outcome was 24-hour cumulative morphine equivalent consumption. The secondary outcomes were pain scores, time to first request for rescue analgesia, and rates of postoperative nausea and vomiting (PONV).
RESULTS
In total, 36 RCTs were included. Network meta-analyses indicated that the erector spinae plane block provided superior analgesia in terms of reduced morphine consumption, low PONV incidence, and longer time to first analgesia request. Moreover, compared with control (i.e., sham or placebo), the quadratus lumborum block provided superior analgesia in terms of time to first analgesia request and resting pain scores.
LIMITATIONS
(1) Few studies have examined single-injection regional analgesia techniques other than the transversus abdominis plane block (TAPB) and wound infiltration, leading to a few indirect effect estimates. (2) Heterogeneity existed due to analgesic type/dose, plane block timing, and injection site. (3) Objective outcomes, such as length of hospital stay, were lacking; most studies only included the patient-reported subjective pain score.
CONCLUSION
Single-injection blocks are effective analgesic techniques for TAH. Among them, the erector spinae plane block and quadratus lumborum block seem to have superior effects. Further studies should evaluate techniques other than TAPB and wound infiltration to draw definitive conclusions.

Prior abdominal liposuction can be viewed as a relative or absolute contraindication to abdominally based autologous breast reconstruction given concerns for damaged perforators and scarring complicating intraoperative dissection. This systematic review aims to explore the outcomes of abdominally based breast reconstruction in patients with a history of abdominal liposuction. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-guided literature search was conducted using PubMed, Scopus, and Web of Science from the earliest available date through June 2020. Deep inferior epigastric perforator, muscle-sparing transverse rectus abdominis musculocutaneous (TRAM), superficial inferior epigastric artery, and pedicled TRAM flaps were included for evaluation. Complications included total or partial flap loss, fat necrosis, seroma, delayed wound healing, and donor site complications. After inclusion criteria were applied, 336 nonduplicate articles were screened, yielding 11 for final review, representing 55 flaps in 43 patients. There was no instance of total flap loss, eight (14.5%) flaps developed partial loss or fat necrosis, three (5.4%) flaps had delayed wound healing, and two (4.6%) patients had donor site complications. Most authors (8/11) utilized some type of preoperative imaging. Doppler ultrasonography was the most used modality, and these patients had the lowest rate of partial flap loss or flap fat necrosis (8%), followed by those without any preoperative imaging (10%). In conclusion, this review supports that patients undergoing abdominally based autologous breast reconstruction with a history of abdominal liposuction are not at an increased risk of flap or donor site complications. Although preoperative imaging was common, it did not reliably decrease complications. Further prospective studies are needed to address the role of imaging in improving outcomes.
