Summary
Free and pedicled flaps show similar complication rates and functional outcomes for extremity soft tissue sarcoma (ESTS) reconstruction. Individualized selection of flap type is key for limb preservation and minimizing morbidity.
Area of Science:
- Orthopedic Surgery
- Surgical Oncology
- Reconstructive Surgery
Background:
- Flap reconstruction is crucial for limb preservation in extremity soft tissue sarcoma (ESTS).
- The comparative impact of free versus pedicled flaps on complications and function after ESTS reconstruction remains unclear.
Purpose of the Study:
- To directly compare postoperative complication rates and functional outcomes between free and pedicled flap reconstructions in ESTS patients.
Main Methods:
- A retrospective review of 266 patients undergoing flap reconstruction for ESTS.
- Logistic regression analysis to assess flap type and complication associations.
- Functional outcomes evaluated using TESS and MSTS scores.
Main Results:
- No significant difference in overall complication rates between pedicled (32%) and free flaps (38%).
- In the upper limb, pedicled flaps showed lower univariate complication rates, but this was not significant in multivariate analysis.
- Obesity (BMI ≥ 30 kg/m²) was a significant predictor of complications in the upper limb.
Conclusions:
- Free and pedicled flaps yield comparable postoperative complication rates and functional outcomes in ESTS reconstruction.
- The choice of flap should be individualized to optimize limb function and minimize complications.

01:24Role of Affect in Interpersonal Attraction
235
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

01:29The Influence of Affect on Cognition
301
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

01:29The Influence of Cognition on Affect
226
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.

Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.
